Operating Instructions

Using an effects processor

IMPORTANT: When using an effects processor, determine and use the proper connection

method (serial or parallel) for your application. Some effects MUST be hooked up in serial.

With the serial method, the complete signal is routed directly into one or more effects

processors. Serially connected effects processors are connected in a chain and the signal is

processed sequentially. Nearly all "stomp boxes" for guitars work this way, such as, an

overdrive followed by a reverb.

In a serial effect hookup, the order in which effects are connected together matters. For

example, it makes a big difference whether you run first through the overdrive and then the

reverb, or first through the reverb and then through the overdrive.

Note: Always connect electronic equalizers, compressors, and limiters in serial.

The parallel method is mainly implemented in conventional mixers through "aux" or "effect"

send/return connections and controls. Effects processors get the original

(unprocessed) signal as an input. The output of effects processors is then added together

and summed with the original clean signal. There is a component of the original signal

present in the output, such as reverb and delay, which are used for vocals.

Note: The parallel method mixes the original signal with the processed version. In the case of an

equalizer, this generates highly undesirable interference and potential phase cancellation. Many

digital effects processors have an internal processing delay, which is applied to the signal, even

if no effect setting is applied. Mixing this delayed output with the original signal can result in

unintended comb filtering.
