1 RCA BA-6A LIMITERS Operation: Apply power to the limiters and allow them to warm up during your setup. The meters will light up. If not, check that the power switch on the chassis of each limiter is on. A balance check will not normally be needed. See balance instructions. Turn the input and output controls to the marks, (unity gain). Turn the BAL-LIM switch to Limit - Single. Turn the METER switch to GR, (gain reduction). Switch, stereo, fast, and slow switches down, (off), on the panel between the limiters. The units are now ready to be used. Mono: Apply a 600 ohm balanced line source from a pre-amp, an EQ, or console buss out, to the input of the limiter. Connect the output of the limiter/s to the Line In of the recording device, the A to D converters, or the console. Observing the limiter meters, adjust the controls of the source to obtain the desired amount of limiting. Monitor and adjust the console or recording device on the output of the limiter for normal levels. Normally it should not be necessary to move the limiters input and output controls off the marks. Typically 5 db of limiting is desired, though very dynamic instruments or singers may cause up to 20 db of limiting. If in that circumstance the Pre or EQ feeding the limiter starts to distort, raise the input control 6 db. Three clicks at 2 db per click, and lower the pre-amp or source gain. Stereo: Does not apply to unmodified unit. Start with the stereo switch off. Connect the limiter to left and right inputs and outputs as above. Adjust the pre-amp gain or console output until limiting begins. When the meters are showing equal limiting on both sides, left and right, switch to stereo (up). See notes. Fast slow switches: Does not apply to unmodified unit. Start with these off, (down). Monitor and study the effect of these switches as you try them. Raising the fast or slow switches will quicken or slow the release time respectively. Using one switch in stereo mode will give half the effect. Using both slow and fast at the same time will slow the attack time, possibly improving the attack of drums. Limit single/double: Turning the BAL/LIM switch to "double", will introduce an element of compression as well as limiting, since the gain reduction will not completely release for several seconds. It's intended to adapt to a section of program that is louder than normal without excessive pumping of the limiter. Notes: This is about the modification. The 1/4" phone plugs from the panel between the limiters must be plugged in to each limiter for the panel switches to work. When they are all down it is electronically the same as not having them plugged in. This is the factory normal. In the stereo mode, left and right program material will both contribute to total limiting. The limiting is kept equal to prevent drift of any center channel information. This is needed when limiting a mix with center channel elements. This might be a finished project or a stereo mix of drums. The snare or vo
