This input allows the connection of backing tracks etc. to be mixed in post the FX loop.
5. FX LOOP
a. FX RETURN
A 1/4" mono jack socket for the connection of the output of an external FX unit. This can
also be used as a slave in for the power amp. As the FX Loop is an insert type, the preamp
signal will be muted.
The FX LOOP SWITCH selects the FX Loop mode of operation:
• Bypass - Removes the FX Loop from the signal path.
•
0dBu - For connection of FX units with a 0dBu nominal output level.
•
-10dBu - For connection of FX units with a -10dBu nominal output level. As this is
intended for devices with a lower output level, this switch increases the gain of the
FX Loop by 10dB.
b. FX SEND
A 1/4" mono jack socket for connection to the input of an external FX unit. This can also
be used as a line out for connection to another power amp slave input or for recording.
6. FOOTSWITCH REMOTE
Connect the included FS4 FOOTSWITCH using the supplied 5 pin DIN cable. This will
provide the user with remote operation of the following functions: CHANNEL, CLEAN,
REVERB, AND BOOST.
7. SPEAKER OUTPUTS
The BCC-IRT30-112 is equipped with a 12" HH Acoustics H1280 8Ω loudspeaker which
should always be connected to the 8Ω socket, with the impedance selector switch set to
8Ω, when used without an extension cabinet. When using an extension cabinet (the
GS112FE / GS212FE / GS412IA or GS412IS are recommended), or any other 8Ω cabinet
in conjunction with the internal speaker, use the 8-16Ω socket with the impedance
selector switch set to 4Ω. Mismatching your speaker impedance will reduce the
performance of your amplifier, and in extreme cases may damage the unit Always operate
this amplifier with a load connected. Failure to do so could result in serious irreparable
damage to the unit!
8. SAFETY WARNINGS Take note of the safety information on the rear panel.
