Should You Use One Or Two Inputs To Effects - Alesis Studio 32 Reference Manual

Effects and Signal Processing

Should you use one or two inputs to effects?

If your effect unit has two inputs, in most cases you only need to connect from ONE
Aux Send to the LEFT (mono) INPUT of the effect unit, but you will still connect
both the LEFT and RIGHT OUTPUTS of the effect to the Stereo Aux Return.
You may not need to connect anything to the right input of the effect, since many
effect units use it only if the effect is connected directly between an instrument and
an amplifier. In most mixing applications, you will set the effect's wet/dry balance
all the way to wet. The effect device will generate an artificial stereo output from
the signal input. Check the manual for your effect device for more information.
On the other hand, true dual-channel effects processors (such as the Alesis Wedge
and QuadraVerb 2) should be connected to two different sends to take advantage of
the dual processing capability.
Using MONITOR 1/2 as effects sends
Note that Mon 1 and 2 can also be used as extra effect sends while mixing.
Although Mon 1 and 2 are pre-fader, and normally used for monitoring while
recording, they are perfectly suitable as effect sends, especially during mixdown,
when you will want to maximize your ability to add effects to independent
channels. Just remember that when you move a FADER up or down you won't be
changing the level going to the effect via MON 1/2, since "pre-fader" means that
they are independent of fader movement (the signal is not affected by the
