They can be used with just about any professional or semipro instrument, effect or tape player. To learn how signals are routed from these inputs: . To wire your own cables: . In the stereo audio world, an odd-numbered channel usually receives the "left signal." For example, you would feed the MS1202-VLZ's line inputs 5-6 a stereo signal by inserting the device's left output plug into the channel 5 jack, and its right output plug into the channel 6 jack. When connecting a mono device (just one cord), always use the LEFT (MONO) input (LINE IN jacks 5, 7, 9 or 11) and plug nothing into the RIGHT input (LINE IN jacks 6, 8, 10 or 12)- this way the signal will appear on both sides. This trick is called "jack normalling" . EFFECTS: SERIAL OR PARALLEL? The next two sections toss the terms "serial" and "parallel" around like hacky sacks. Here's what we mean by them. "Serial" means that the entire signal is routed through the effects device. Examples: compressor/limiters, graphic equalizers. Linelevel sources can be patched through a serial effects device before or after the mixer, or preferably through the insert jacks located on the rear panel (CHANNEL INSERT send/return). "Parallel" means that a portion of the signal in the mixer is tapped off to the device (AUX SEND), processed and returned to the mixer (STEREO AUX RETURN) to be mixed with the original "dry" signal. This way, multiple channels can all make use of the same effects device. Examples: reverb, digital delay. (See diagrams below.)
