(OVERRIDES INTERNAL EFX)
The
EFFECTS SEND
jack is a 1/4" connector
that produces an unbalanced line-level signal.
This signal is fed from the internal EFX bus,
just after the
EFX DRIVE LEVEL
control.
Use a cable with 1/4" TS plugs to connect the
EFFECTS SEND
jack to the input of an external
effects processor. Use a similar cable (or cables)
to return the external effects processor’s signal
to the
EFFECTS RETURN
jack(s).
The mono versions (406M, 408M, 808M)
have one
EFFECTS RETURN
jack and the stereo
versions (408S, 808S) have two
RETURN
jacks.
These are 1/4" connectors that accept an un-
balanced line-level signal.
The
EFFECTS SEND
and
RETURN
are
normalling jacks, so with nothing plugged into
the
SEND
or
RETURN
jacks, the internal ef-
fects signal from the
EMAC
is routed to the
EFX TO MON
and
EFX TO MAIN
controls. If
you plug a 1/4" TS plug into the
EFFECTS RE-
TURN
jack(s), the effects signal from the
EMAC
is disconnected from the signal path.
Instead, the external effects signal is routed to
the
EFX TO MON
and
EFX TO MAIN
controls.
Note:
If you want to use the internal
EMAC
and an external effects processor at the same
time, you have two options.
Serial effects device:
The
EFFECTS SEND
jack is wired the same as the channel
INSERT
jacks, so you can use it to insert a processor in
series with the
EMAC
effects. Refer to the
“Channel Inserts” section
to see how to
make this connection.
Parallel effects device:
Plug a TS plug half-
way into the
EFFECTS SEND
jack (to the first
click). This allows you to use the
EFFECTS
SEND
jack as a direct out without affecting the
signal going to the
EMAC
. However, you must
use one of the
LINE
inputs (or one of the stereo
channel’s stereo line inputs if it’s a stereo pro-
cessor) to return the signal from the external
effects processor. If you plug into the
EFFECTS
RETURN
jack, the signal from the
EMAC
is dis-
connected from the signal path.
EFX FOOT SWITCH
You can connect a normally-open foot
switch to this connector to duplicate the
function of the
EFX BYPASS
switch. Closing
the switch connection causes the
EFX BYPASS
indicator to light and mutes the effects signal.
This affects both the internal
EMAC
and an
external effects processor (if connected) using
the
EFFECTS SEND
and
RETURN
jacks.
Note:
When a foot switch is plugged into the
FOOT SWITCH
jack, the
EFX BYPASS
switch
is disabled.
POWER AMP IN 1 and 2
This is a 1/4" connector that accepts an un-
balanced line-level signal. Whatever signal you
plug into these jacks is routed to the power
amplifier inputs. This provides the ability to in-
sert a processor in the signal path between the
MIXER OUT
and the
POWER AMP IN
.
