ˇ Set Normal/LFE Switch to LFE. ˇ Set Normal/LFE Switch to Normal. NOTE: In this case, you do not need to use a Y connector. Simply connect the LFE output on your receiver/processor to either the left or right input on the subwoofer. NOTE: Some receivers have a single subwoofer output (do not confuse this with a single LFE output as described to the left). In that case, it is recommended that you use a Y connector (not included) to maximize performance.

The Cascade Model Twelve also includes a set of line outputs.These outputs allow you to "daisy-chain" one Model Twelve to multiple Model Twelve subwoofers. Simply connect the first subwoofer as described above and then run a subwoofer cable from the line output(s) to the line input(s) on the next sub. NOTE:This line output is before the R.A.B.O.S. circuit. Each subwoofer's R.A.B.O.S. controls must be individually adjusted during the R.A.B.O.S. setup.

OPERATION
Power On
Plug your subwoofer's AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Initially set the Subwoofer Level (Volume) Control § to the "min" position. Turn on your sub by pressing the Power Switch Ą on the rear panel.

Crossover Adjustments
NOTE: This control will have no effect if the Normal/LFE Selector Switch ś is set to "LFE." If you have a Dolby Digital or DTS processor/receiver, the Crossover Frequency is set by the processor/receiver. Consult your owner's manual to learn how to view or change this setting. The Crossover Adjustment Control determines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz.This will concentrate the subwoofer's efforts on the ultradeep bass sounds required by today's films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment Control to a higher setting, between 120Hz and 150Hz.

Auto On/Standby
With the Power Switch Ą in the ON position, the Power Indicator LED ˘ will remain backlit in red or green to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected, Amp Off) GREEN = ON (Signal detected, Amp On) The subwoofer will automatically enter the Standby mode after approximately 10 minutes when no signal is detected from your system.The subwoofer will then power ON instantly when a signal is detected. During periods of normal use, the Power Switch Ą can be left on.You may turn off the Power Switch Ą for extended periods of nonoperation, e.g., when you are away on vacation.

Phase Control
The Phase Switch ˇ determines whether the subwoofer speaker's piston-like action moves in and out with the main speakers, 0,° or opposite the main speakers, 180°. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.

Adjust Gain
Turn on your entire audio system and start a CD or movie soundtrack at a moderate level.Turn up the Subwoofer Level (Volume) Control § about half way. If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact? Is the AC plug connected to a "live" receptacle? Has the Power Switch Ą been pressed to the "On" position? Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information. Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the Subwoofer Level (Volume) Control § until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass.This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive.

Cascade Model Twelve TEST PROCEDURE

The operation of the Cascade Model Twelve subwoofer, and the proper settings for the Room Adaptive Bass Optimization System, or R.A.B.O.S., is thoroughly covered in the Owner's guide, part# 406-000-05338-E. For service purposes, the R.A.B.O.S. system is canceled when all three front panel controls (F) (L) (W) are turned fully CW (Clockwise), or if the R.A.B.O.S. On/Off switch is OFF. The only other control of concern is the Main Level Control on the front panel, which operates like a traditional potentiometer.

Equipment needed: ˇ Function/signal generator/sweep generator ˇ Integrated Amplifier ˇ Multimeter ˇ RCA cables; Speaker cables General Unit Function (UUT = Unit Under Test) Switch/Controls: MAIN LEVEL control full Counterclockwise (Min) CROSSOVER (Hz) Full Clockwise (150) R.A.B.O.S. On/Off switch OFF PHASE switch - either position (3) R.A.B.O.S. controls do not matter 1) From the signal generator, connect one line level (RCA) cable to the Line In jacks (L/R) on the UUT. Use a Ycable from a mono source if necessary to connect to both inputs. 2) Turn on generator; adjust to 150mV, 50 Hz. 3) Plug AC power cord in UUT, turn power switch ON. 4) LED should be ON (faceplate). Turn up LEVEL control to full Clockwise (Max). 5) LED should be Green; Bass response should be heard and felt from woofer at bottom of cabinet. 6) Turn LEVEL control full Counterclockwise (Min). Turn power switch OFF. Sweep Function 1) Follow steps 1-5 above, using a sweep generator as a signal source adjust the generator to 100mV, 50 Hz. 2) Sweep generator from 20Hz to 300Hz. Listen for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, test woofer according to the instructions below. Driver Function 1) Remove woofer from the enclosure. Check DC resistance of woofer; it should be 3.4 ą10%, 2) Connect a pair of speaker cables to woofer terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 6.0V. 3) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
