The output/s of mono or stereo effects processors would be connected here. If an effects
processor is mono, plug its output into the L/Mono Aux Return jack or use a 'Y' cable to the
Efx 2 Return jacks. If it's stereo, use both jacks. Signals coming into the Efx 2 and/or Aux
Return jacks are routed to the Efx 2 and Aux Return masters so that their mix levels to both
Mon 1 and Mon 2 channels and the L/R main P.A. channel can be regulated precisely.
These jacks may alternately be used to connect another audio source, e.g. digital
audio players, CD-player, tape decks, instrument amp line out, keyboard or even
another mixer. The Efx 2 and Aux Return Masters regulate their mix levels to the main
and monitor systems. The EFX2 and Aux Return jacks are balanced, but will work
with either balanced or unbalanced cables. For optimum, quiet performance, use bal-
anced patch cords whenever possible.
24. Return Levels Masters, Solos and Clip LEDs
Efx 1 is the internal effects processor bus. The Efx 1 Return masters are between its
output and the internal inputs to the Mon 1, Mon 2 and L/R (main) busses. The Efx
2 and Aux Return masters are between their respective Return jacks and the internal
inputs to the Mon 1, Mon 2 and L/R (main) busses. Solos can be PFL or AFL as per the
Solo Mode button setting. In mono effects mode Efx 2 gets signal from intenal-Efx 2.
Efx 1 Return features a Defeat LED to indicate that the effect has been muted by the
Internal Efx Defeat Footswitch.
These Masters permit mixing internal and/or external effects or other input signals to
the Mon 1 and Mon 2 monitor channels and the L/R main channel. The Solo buttons let
you preview through headphones whatever signals are coming into each Return Levels
channel before turning up these masters (Solo Mode button set for PFL) or after they
are turned up (Solo Mode at AFL). The Solo LED stays on to indicate that Solo is active.
Remember to depress the button again when you are finished soloing.
Aux Clip and Efx 2 Clip/Defeat indicate excessive signal levels coming in via the Aux
Return. This can mean that the Efx 2 Send fader or the Aux Master Send levels are set
too high causing the effects units to put out too much signal. Turn them down. Trying to
reduce clipping at this stage by turning down the Return Levels masters will not work.
Clipping is more likely to
happen when a high-output
audio source, possibly
another mixer or an instru-
ment amp's line output, has
been connected to one or
both of the Return jacks. In
this case lower that mixer's
(or whatever's) master level
or other volume controls
until the Clip LED goes out.
Again, do not try to rem-
edy the problem by turning
down the Return levels. Efx
2 Clip/Defeat LED indicates
that the effect has been
muted by the Internal Efx
Defeat Footswitch. This
footswitch mutes only the
internal effects. An external
device should have its own
footswitch.
