Loop Effects. (Also referred to as Send and Return Effects)
A loop effect uses an auxiliary bus to split a signal off from a channel to send a selectable
amount of signal into an effects processor. The effected signal is then returned from the
effects processor's output and summed with the original signal. This will give you a
combination of "dry" signal and "wet" (effected) signal. The amount of "wet" signal is
determined by a channel's effects send. The higher the send the more effected the sound
will become. A send can be a prefade or postfade send.
A prefade signal as it applies it to an aux bus is unaffected the amount of "dry" signal. If
an aux bus is set to be prefade it gets its signal before the channel's fader. That means
that the only its send level determines the amount of signal being sent and not the
channel's fader. The fader will only control the "dry" signal. For example if the fader is
all of the way down and a prefade send is going to an effect then you will only hear the
effect and not hear the dry signal. This would not be very desirable in most situations.
Prefade busses are most useful for setting up headphone or monitor mixes and not for
using as effects sends on mixers.
A postfade bus gets its signal after the fader on a channel. You can still control the
amount of send level but it will change proportionately to the amount of the channel's
fader level or "dry" level. In other words the send level is set in relation to the dry level
but the amount being sent to the effect will increase as the channel's volume increases
and it will decrease as the channel's volume decreases. A post fade send is what you
would typically use for sending signals to effects processors.
The individual sends for the LOOP EFFECTS on the BR-1180 are post fade sends.
To apply Reverb to the MIC 1 input, use the following procedure:
1) Press REVERB.
2) CURSOR to the left to highlight IN.
3) Use the TIME/VALUE wheel to increase or decrease the amount of reverb being
applied to the mic input.
You can CURSOR to each individual track to enable you to adjust the reverb amount
for your recorded tracks or you can simply press the status button for the track that
you want to affect and the turn the VALUE/WHEEL.
