You've heard us carelessly toss around the terms "serial" and "parallel." Here's what we mean by them: "Serial" means that the entire signal leaves the mixer (INSERT send), is routed through the effects device, and returns to the mixer (INSERT return). Examples: compressor, limiter, graphic equalizer. Line-level sources can also be patched through a serial effects device before or after the mixer. "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 (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. AUX RETURN INPUTS This is where you connect the outputs of your parallel effects devices (or extra audio sources). They'll accept just about any pro or semipro effects device on the market. See page 26 for details of the AUX RETURN level controls. Mono: If you have an effects device with a mono output (one cord), plug that into L input of an AUX RETURN and leave the right input unplugged. That way, the signal will be sent to both sides, magically appearing in the center as a mono signal. SUB OUTS These 1/4" jacks are usually patched to the inputs of a multitrack deck, or to secondary amplifiers in a complex installation. See page 22 for details of the SUBGROUP FADERS . Double Busing How on earth do you get four buses to feed eight tracks? Double busing! • Bus 1 feeds SUB OUT 1 and SUB OUT 5, which in turn feed tracks 1 and 5 • Bus 2 feeds SUB OUT 2 and SUB OUT 6, which in turn feed tracks 2 and 6 • Bus 3 feeds SUB OUT 3 and SUB OUT 7, which in turn feed tracks 3 and 7 • Bus 4 feeds SUB OUT 4 and SUB OUT 8, which in turn feed tracks 4 and 8 Tracks in record mode will accept the signal, and tracks in safe mode will ignore the signal.
