PSA-1
The History of Tech 21's SansAmpTM Tech 21, Inc., introduced SansAmp "Classic" (the original pedal design) in 1989. Our proprietary F.E.T. hybrid-based circuitry pioneered Tube Amplifier Emulation for professional applications. Engineered for direct recording and live performances, SansAmp delivers consistent quality sound --studio to studio, club to club, arena to arena. Players, engineers, and producers can now obtain a wide spectrum of warm, natural tube amplifier sounds from one convenient unit. Available in various formats, each SansAmp is suitable for any music style, from jazz to metal, and can be used with a variety of instruments --guitar, bass, keyboards, samplers, even sax and vocals. The SansAmp Classic was conceived and developed by a guitarist who possesses the unusual combination of a trained ear and electronics expertise. The technology is designed in the true tradition of tube amplifiers in their totality--with a pre-amp stage and an output stage. It incorporates the harmonics and sweet overdrive characteristics unique to tube amplifiers-- largely caused by what is referred to as "push-pull" symmetrical clipping. (A single tube is physically incapable of accomplishing the same results.) SansAmp captures these characteristics, and does so even at low volume levels. SansAmp gives you the most coveted trademarked sounds and the flexibility to refine and redefine your own. Each model responds to and interacts with the dynamics of your individual playing style, your individual musical style, and your instrument's individual tonality. All of these factors play an important role in the resulting sound, which will ultimately be yours alone. Designed & Manufactured in the U.S.A. TECH 21, INC.

instrument. For live performances, it can be used as a pre-amp direct into a power amp with guitar or bass speaker cabinets, as a "monster direct box" to a P.A. system, (or both simultaneously), and as an outboard processor. The SansAmp PSA-1 features MIDI capability for calling up programs and storing program data. There are 49 factory presets and 49 memory locations to store your own custom sounds, plus two bypass programs. When you switch between programs, there is no lag time, or "cutting out." The controls on the SansAmp PSA-1 work very much like those found on a sophisticated amp. You don't need special training or a degree in physics to operate your unit. Storing and recalling programs is simple: set your tones and push the Save button. Like the SansAmp Rackmount, you just turn a knob and hear the difference immediately --in real time. There are 256 incremental steps in the rotation of each control, so increases and decreases occur in a smooth, gradual, linear fashion. The SansAmp PSA-1 is designed to provide you with the flexibility to find almost any conceivable tonal personality within the tube amplifier sound spectrum.

QUICK START INSTRUCTIONS
Here's how you can get your PSA-1 up and running before you read the entire manual. 1. Plug your instrument into the front-panel Input jack (on the left side). 2. Plug one end of a cord into the rear panel's left Output jack, and plug the other end into the input of a mixer or an amp or power amp. 3. Plug the AC cord into a wall socket. The SansAmp PSA-1 is now on. 4. Turn on your amp or mixer. (If the mixer is patched into a monitor or recorder setup, make sure the power amp and speakers are turned on, too.) 5. Turn up the input level on your amp or mixer. If the signal is too "hot," resulting in unwanted distortion, or too weak, check the amp's or mixer's input control as well as the Output Level Switch on the back of the SansAmp PSA-1. 6. Play your favorite riff or chord changes, and you should hear a sound coming through your system. If not, recheck your connections, and make sure your guitar's volume control is turned up. 7. Select programs by pushing either the Up or Down buttons. The first 49 presets (01-49) are factory settings (refer to the list on page 22), and the second 49 programs (51-99) are storage locations for you to keep your settings. Note that the unit is shipped with programs 51-99 as duplicates of presets 01-49, and that 00 and 50 are bypass settings. If you need further guidance in setting up your SansAmp PSA-1, check out the diagrams and information on pages 12 through 14.

INTRODUCTION
SansAmp PSA-1 maintains its superior tone with our exclusive, 100% analog circuitry. Only the programming and memory sections are digital. The results are easy to hear: punchy, responsive, powerful sounds that bring out the best in an instrument--the kind of tones that characterize the original SansAmp Classic, SansAmp Bass DI, SansAmp GT2, and SansAmp Rackmount. The SansAmp PSA-1 can be used for a variety of applications. In the studio, you can record direct to tape, enhance existing tracks in mixdowns, as well as add interesting touches to any

INSTALLATION POWERING THE SANSAMP PSA-1
The SansAmp PSA-1 is powered by potentially hazardous voltage. Therefore, observe the following safety precautions. WARNING: To avoid the risk of shock or fire, do not expose this unit to moisture. Do not remove the chassis from its cabinet, or remove metal covers from chassis parts. Removing the chassis from its cabinet exposes extremely dangerous high voltages. There are no user-serviceable parts inside. Hazardous voltages are present inside the chassis. Refer all servicing to qualified personnel. CAUTION: Never modify the AC power cord. If the original AC power cord becomes damaged, refer your SansAmp PSA-1 for servicing. WARNING: Attempting to repair this unit is not recommended and will void its warranty. NOTE: In the U.S. and Canada, servicing of SansAmp PSA-1 is performed at factory only. In other countries, please refer repairs to the local Tech 21 authorized distributor.

PSA-1
Because the SansAmp PSA-1 is fully programmable, everything you do is monitored by the SansAmp PSA-1's internal computer. Whenever you turn a knob from the setting stored in memory, one of the two dots in the upper left corners of the LED Dots numerical display blinks.
Blink

This feature is useful when you want to know the position of each knob's setting in the memory. Here's how to use it:: Assume that the preset point for a particular knob is 12 o'clock. When you turn that knob, it "unlocks." One of the two dots above the digits in the LED numerical display will blink. The arrows above the LED display tell you which direction you need to turn the knob to find the preset point. The up arrow tells you to increase the setting; the down arrow tells you to decrease. If you are far below the preset point, the left dot blinks slowly. Follow the direction of the arrow (up) and increase the setting. As you get closer to the preset point,

FRONT PANEL
The SansAmp PSA-1 gives you access to specific tone-shaping characteristics within the tube amplifier sound spectrum. Controls of this nature are traditionally inaccessible on stock amps, and adjustments like these can ordinarily be achieved only by permanent professional modification. Tonality, for instance, can be adjusted in a variety of ways. The individual Character Controls, labeled Buzz, Punch, Crunch, and Drive, offer different results than the post EQ section (the controls labeled Low and High). The gain structure can be adjusted via the Pre-Amp control, which results in a different kind of overdrive than the Drive control. Additionally, Buzz, Punch, and Crunch each affect the gain structure within specific frequency bands. As you experiment and become familiar with the controls' interrelationships, you'll be able to customize your own sounds and store them in the SansAmp PSA-1's memory. the dot blinks faster. If you turn the knob past the preset point, the right dot will first blink fast and then slow as you turn farther clockwise away from the preset point. When you reach the preset point, both dots stop blinking and go dark.

INPUT JACK
This 1/4" Input features an impedance buffer so that the tone from a guitar's or bass' pickups, or the signal from other instruments, reaches the SansAmp PSA-1 without degradation. A second input jack is located on the rear panel. Note: plugging into the front-panel Input jack overrides and disconnects the rear-panel jack. This lets you set up your SansAmp PSA-1 as a permanent part of a rack or patch-bay setup, with its usual input source plugged into the rear-panel jack. Then, if you want to plug straight into the SansAmp PSA-1, bypassing other parts of the system, you can use the SansAmp PSA-1's front Input.

PSA-1
This is the input sensitivity control. The Pre-Amp control adjusts the signal level going into the input section of the SansAmp PSA-1. The arrows in the surrounding circle symbolize the unityINPUT PRE - AMP gain point (that is, no boost or cut). When clean sounds are desired with the use of a hot-output instrument, decrease from the unity-gain point. Increasing the position of the Pre-Amp control produces an effect similar to putting a clean booster pedal into the input of a tube amp. To achieve the least amount of noise, keep the Pre-Amp knob at unity gain or higher. Experiment with the interplay between your instrument and the SansAmp PSA-1. Note: For best results, do not set the Pre-Amp level lower than unity gain when the Drive knob is at 9 o'clock or higher. However, if you want a crystal-clear sound and the Drive control is already near minimum and there's still too much overdrive, decrease the Pre-Amp's level as needed. Pre-Amp also influences different types of overdrive. For instance, a high setting emphasizes pre-amp distortion (see Boogie® Lead-style setting), as opposed to when Drive is in a high setting, which emphasizes power amp distortion (see Vintage Marshall®-style setting).
Arrows indicate unity-gain point

PSA-1
PUNCH
The Punch control sets the amount of midrange break-up and overdrive. Boost or cut from the center point indicated by the arrows. Decreasing from the center point produces a softer, Fender®-style break-up. Increasing its setting creates a harder, heavier distortion. At maximum, it produces a sound similar to a wah pedal at mid-boost position placed in front of a Marshall® amp.

PRE-AMP

CRUNCH
The Crunch control brings out the upper harmonic content and pick attack. For a smoother high end and for clean settings, decrease to taste.

DRIVE
Like the volume control on a non-master-volume tube amp, Drive increases the amount of power amp distortion. In live applications, we recommend using less Drive than when direct recording. This compensates for the natural sustain of high volumes.

LOW
This active low-end tone control is specially tuned for maximum musicality when used to EQ instruments. Boost or cut by ±12dB by turning from its center point indicated by the arrows.

HIGH CHARACTER CONTROLS
BUZZ PUNCH CRUNCH DRIVE

This active high-end tone control is specially tuned for maximum musicality when used to EQ instruments. Boost or cut by ±12dB by turning from its center point indicated by the arrows.

LEVEL
This one control simultaneously adjusts the output level of the rear-panel XLR and 1/4" outputs.

2-DIGIT LED DISPLAY
Continuously variable Character Controls offer tremendous flexibility in adjusting tonality, gain structure, and harmonic content. Everything you need to know is in SAVE DOWN UP these two digits. This display is readPUSH 2X able from any angle, in daylight or darkness. It tells you which program is active, whether any knob's setting has been changed, when a program is stored, and when MIDI functions have been activated. Refer to the sections on programming your SansAmp PSA-1 and using MIDI for specific information regarding the display's functions.

BUZZ
The knob labeled Buzz controls the low-end break-up and overdrive. You can boost the effect by turning clockwise from the center point indicated by the arrows, and cut by turning counterclockwise. When you turn towards maximum, the sound becomes (you guessed it) buzzy. For a clean setting, increase the setting in small increments. For increased definition when using distortion, position the knob at its midpoint or towards minimum.

SAVE SWITCH
The Save switch stores your custom settings in the memory of the SansAmp PSA-1. It also gives you access to the Special Page function menu. It is purposely recessed into the front panel to make it difficult to inadvertently push. You can use a guitar pick, a pen tip, or a wellplaced fingernail to push it.

DOWN SWITCH
Pushing this switch once counts down through the programs one at a time. Holding it down moves quickly through them.

UP SWITCH
Pushing this switch once counts up through the programs one at a time. Holding it down advances quickly through them.

SAVING A PROGRAM
When you've created a sound you like and want to save the setting, follow this procedure: 1. Push the Save switch once. Both digits of the display blink on and off. 2. Use the Up or Down switches to select a program number (51-99*) where you want to save the program. 3. Push the Save switch a second time. The display will "run around" three times and then show the selected program number (it will stop blinking). That's it. You've stored a program. *Programs 00 - 50 are permanent factory presets and cannot be overwritten. Additionally, 00 and 50 are
permanent bypass programs for the instrument signal to pass straight through the SansAmp PSA-1.

Plugging into Input 2 lets you match the SansAmp PSA-1's input circuitry to the signal level being fed into it, thereby assuring the best signal-to-noise ratio and least distortion. This input is ideal for rack and patch-bay applications, especially if you use other signal processors or multi-track recorders before the SansAmp PSA-1. Note: Whenever you plug into the front panel's Input, the rear panel Input 2 is disconnected. Also, you can set the Input level selector switch to its 0dB position when you plug in extra-hot signals, such as the output from active bass guitars.

Be careful not to overwrite a program that you wanted to keep, since the new program will entirely wipe out the old one that was in the same memory location. Accidents can happen, so it's a good idea to keep track of what's in each of your programs. Make photocopies of the

This switch lets you connect the SansAmp PSA-1 to a wide variety of equipment with a variety of signal levels. It has two positions: 0dB position. This engages the input pad. Set the switch in this position when sending a line-level signal into the SansAmp PSA-1. When the switch is in this position, the signal coming into the unit is padded down by 10dB. -10dB position. When the input pad switch is disengaged (at its -10dB setting), the rear panel Input 2 is optimized to receive an instrument level signal. In this position, Input 2's sensitivity is exactly the same as the front panel's Input.

blank diagrams on pages 24-25. Each time you save a program, write in the knob settings and give each program a name (song title, description of the tone, etc.) for easy reference later. Remember that you can't overwrite the factory presets. If you try to save over a factory preset, you will get a flashing letter "E" that tells you you're making an error. Note: You can also off-load your custom presets to a computer, sequencer, etc., using a Custom Preset Data Dump. For more on this, see page 16.

EFFECTS LOOP EFFECTS SEND
This jack sends the SansAmp PSA-1's signal to processors. When nothing is plugged into the Effects Loop, the signal passes through from the SansAmp PSA-1 to the Output jacks, with

both the left and right Output jacks receiving the same signal. Note: The Effects Loop Send is muted in bypass programs.

PSA-1
XLR OUTPUT JACKS
The SansAmp PSA-1's two XLR Outputs are designed without transformers to provide a low-impedance output of extremely high quality for recording or interface with professionalquality signal processors. (It includes any effects that are placed in the Effects Loop.) XLR and 1/4" Outputs may be used simultaneously. Minimum output impedance is 600 ohms.

MIX 50/50 SWITCH
The 1/4" Send routes 100% of the SansAmp PSA-1's signal through your effects processor when the 50/50 switch is disengaged. If you engage the 50/50 switch, then 50% of the SansAmp PSA-1 signal goes through your effects processor, and the other 50% passes directly to the 1/4" and XLR Outputs. To preserve the signal integrity of the SansAmp PSA-1, use the Effects Loop with the 50/50 switch engaged. When the SansAmp PSA-1 is in this mode, the effects processor's mix control should be set at 100% wet. Your relative wet/dry mixture can then be controlled by increasing or decreasing the effects processor's output level.

XLR OUTPUT LEVEL SWITCH
This switch sets the range of the signal level sent out of the XLR Output jacks. When the switch is in 0dB position (engaged), the Output is in the line level range. When the switch is in its -10dB position (disengaged), the Output is in the instrument level range. Note: The standard output level range of the SansAmp PSA-1 is 0dB due to the wide availability of digital recorders, which are unforgiving to excessive input levels. This prevents overloading the input of a digital recorder.

RIGHT RETURN
When using a mono effects processor, plug the processor's output into the SansAmp PSA-1's Right Return. This will route the signal to both pairs of left and right Outputs.

FOOTSWITCH
Any momentary footswitch can be used to step through SansAmp PSA-1's programs. Refer to the section on page 14, "Using MIDI And Remote Footswitch," for details on using a footswitch with the SansAmp PSA-1. Optional factory footswitch, with LED status indicator, is available through your local Tech 21 authorized dealer.

LEFT RETURN
This is one of two stereo returns for the Effects Loop. If your signal processor has only one output (mono), then plug it into the Right Return.

UNIVERSAL OUTPUT SECTION
Another aspect of the technological advancement of the SansAmp PSA-1 is that its output sections are physically compatible with any application. The outputs can be used for full range (multi-track recorders, studio monitors, P.A. systems) as well as limited range systems (guitar or bass speaker cabinets). Note: You can compensate for different frequency responses of speaker enclosures by using the High control.

MIDI MIDI IN
This jack receives MIDI signals, including Program Change commands and MIDI data dumps.

MIDI THRU/OUT
This jack normally functions as a MIDI Thru, which lets MIDI data entering the SansAmp PSA-1 pass through to other MIDI-controlled gear. This is useful when you employ a MIDI footcontroller to control the SansAmp PSA-1 and an effects processor. You can disengage the MIDI Thru by using Special Page Function 9 (see page 21). When you off-load custom preset data or MIDI map data , this jack operates as a MIDI Out. (See Special Page Functions 1 and 7, pages 16 and 21.) Always use good-quality MIDI cables for connecting the SansAmp PSA-1 with other gear.

1/4" OUTPUT LEVEL SWITCH
This switch selects the Output level's range. When this switch is in its 0dB position (engaged), the Output is at line level. When the switch is in its -10dB position (disengaged), the Output is at instrument level.

1/4" OUTPUT JACKS
These left and right 1/4" jacks carry the signal from the SansAmp PSA-1. This includes any effects that are placed in the Effects Loop. The Output level switch (0dB/-10dB) lets you interface the SansAmp PSA-1 with a variety of line and instrument level inputs, including recorders and mixers requiring low-level signals, signal processors, and power amps.

SUGGESTED SETUPS
The following three pages show you how to interface your SansAmp PSA-1 with other gear, including MIDI equipment.

The front-panel Input jack is designed to accept signals from guitars, basses, keyboards, etc. You can set up your SansAmp PSA-1 as a permanent part of a rack or patch-bay setup, with its usual input source plugged into the rear-panel jack. Then, if you want to plug straight into the SansAmp PSA-1, use the front-panel Input, which overrides the rear-panel Input 2.

The Effects Loop lets you patch in reverbs, delays, and other signal processors. If your signal processor has only one output (mono), then plug it into the Right Return. Note: If you engage the 50/50 switch, then 50% of the SansAmp PSA-1 signal goes through your effects processor, and the other 50% passes directly to the 1/4" and XLR Outputs.

SPECIAL PAGE FUNCTION 2: MIDI MAPPING
This function defines internal MIDI mapping. That is, it tells your SansAmp PSA-1 which program to call up when a MIDI Program Change command comes in. For example, if your MIDI footcontroller sends out a Program Change command that says Program 26, and you want your SansAmp PSA-1 to respond to that Program 26 message by calling up preset number 15, you can set the SansAmp PSA-1 to map that message to the appropriate location. The SansAmp PSA-1 comes from the factory with its MIDI map set by default to map incoming programs to the displayed programs. That is, MIDI 01 calls up program 01, etc. The SansAmp PSA-1 has 100 program locations; therefore, any Program Change messages with values greater than 99 are automatically remapped. So, incoming Program Change numbers 100 through 128 are automatically remapped so that 100 calls up 00, 101 calls up 01, and so

Now, if you program the SansAmp PSA-1 to step through only two presets, you can set up rhythm and lead programs for individual songs, and select the grouping with your MIDI footcontroller. For example, you can set up rhythm and lead sounds in Programs 22 and 23 for one song, and rhythm and lead sounds for another song in Programs 24 and 25. Then when you play the first song, select Program 22 using the MIDI footcontroller and step on the momentary switch to go back and forth between Programs 22 and 23. When it's time for the next song, use the MIDI footcontroller to call up Program 24, and then use the momentary switch to toggle between Programs 24 and 25. Set up two, three, or as many presets per song or style you want, according to your needs. You can set up blues groupings, ballad groupings, grunge groupings, metal groupings, etc., and have them all ready to call up at any time.

USEFUL FOOTSWITCH TRICK
If you are using a MIDI footcontroller to call up the programs in your SansAmp PSA-1, you can use still use your momentary footswitch to cycle through a group. For instance, if you select a loop of four programs, as shown in the previous example, then you can step through four programs beginning on any program number, if you use a MIDI footcontroller. Here's how: Use your MIDI footcontroller to call up, say, Program 25, and have your SansAmp PSA-1 set to loop through four programs. Instead of the first program being 00 when you step on the momentary switch, it's 25. The sequence, then as you step on the footswitch, is 25, 26, 27, 28, 25, 26, 27, 28, etc.
