Chapter 7 Using Internal Effects (VS8F-2)
Loop Effects
With loop effects, the original sound and the effected sound 
are mixed together. Effects such as reverbs and delays are 
typically connected using a loop.
fig.05-07
In a loop effect, the original signal is copied and sent to the 
effect. Later in the signal flow, the output of the effect 
processor is mixed back in with the original signal. A loop 
effect provides independent control of the original signal 
(using the channel fader) and the Effect Return Level. All 28 
channels of the VS-1824s mixer can be routed to a single 
effect using a loop effect. For example, you can have up to 28 
different mixer channels routed to the same reverb, with 
different send levels on each channel.
A mixer channel can be connected to a loop effect using 
either of two different switch positions. These are referred to 
as “pre-fader” and “post-fader.”
Pre Fader
With the effect switch set to Pre Fader, the signal is sent to 
the effect before it passes through its channel fader. The 
position of the channel fader has no affect on the amount of 
signal going to the effect. The signal is sent to the effect at the 
level set with the Effect Send Level value.
Post Fader
With the effect switch set to Post Fader, the signal is sent to 
the effect after it passes through the channel fader. The 
position of the channel fader has a direct bearing on the 
amount of signal going to the effect. As the channel fader is 
lowered, the amount of signal going to the effect is lowered. 
As the channel fader is raised, the amount of signal going to 
the effect is raised. As a result, the direct signal and the 
effected signal always stay in proportion.
Making the Effect Connection
The VS-1824 Channel Mixer display provides two different 
areas for connecting effects. One area is used for connecting 
insert effects only, and is labeled “FXIns.” The other area is 
used for connecting loop effects. This area appears at the 
bottom of the Mixer screen, and is labeled “FX1”, “FX2”, 
“FX3”, and “FX4.” To find out if an effect should be 
connected as an insert or as a loop, see “Preset Patch List” 
(Appendices p. 20). Look under “Type.” The Type of effect 
determines which area of the Mixer display should be used 
to connect it.
Procedure for Using Effects
To use an effect in the VS-1824, follow these three general 
steps: 
1. Select the Effect Patch to use.
2. Determine whether the effect should be used as an insert 
effect or in a loop effect. 
3. Connect the effect within the mixer. The exact methods 
for each of these three steps are explained below.
