EFFECTS: SERIAL OR PARALLEL?

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, lim- iter, 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. To learn how sig- nals are routed from these inputs: . To wire your own cables: .

Mono: If you have an effects device with a mono output (one cord), plug that into L in- put 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 in- puts of a multitrack deck, or to secondary amplifiers in a complex installation. To learn how signals are routed to these outputs: .

To wire your own cables: .

Double Busing

How on earth do you get four jacks to feed eight tracks? To feed an 8-track deck with only four SUB OUTS, simply use four Y-cords:

•SUB OUT 1 feeds tracks 1 and 5

•SUB OUT 2 feeds tracks 2 and 6

•SUB OUT 3 feeds tracks 3 and 7

•SUB OUT 4 feeds tracks 4 and 8

Tracks in record mode will accept the signal, and tracks in safe mode will ignore the signal. It’s that easy.
