The Rear Panel
17. IEC POWER INPUT CONNECTOR:
This is where you connect the supplied
AC power cord. Connect it to an AC
mains power supply that has the cor
-
rect voltage and current suitable for
your BA300.
18. EFFECTS LOOP SEND JACK: Use
this ¼" TS unbalanced output to send
a line-level output to an external effects
processor (for example). Use the loop
return jack to feed the returned pro
-
cessed signals back into the BA300.
19. EFFECTS LOOP RETURN JACK: Use
this ¼" TS unbalanced input to return
the processed line-level output of an
external effects processor (for exam
-
ple). Note: Anything plugged in here will
break the internal signal path of your
guitar to the internal power amplifier.
20. LINE OUT LEVEL CONTROL: Use this
to adjust the output level of the ¼" TS
and XLR line outputs.
21. LINE OUT ¼" TS JACK: You can con
-
nect this unbalanced line-level output to
an effects unit, or another power ampli
-
fier (for example). Usually, these would
be nearby components, connected with
short cable runs.
22. LINE OUT XLR JACK: Typically, you
would connect this balanced output
to the balanced input of an external
mixer, or a recorder. In this way, you
do not have to mic the BA300 in order
to add it to the main mix, or to record.
It can also connect to external power
amplifiers, or powered loudspeakers.
Balanced connections allow long cable
runs to be used, as hum and noise
pickup in the line is minimized.
23. LINE OUT PRE/POST: Using this
switch, the line outputs can be either:
Pre (pre–EQ/compressor/preamp/
effects-loop)
Post (post–EQ/compressor/preamp/
effects-loop)
The line outputs are not affected by
adjustments to the master level [15].
24. GROUND LIFT: Use this to lift the
ground connection of the XLR output.
25. TUNER OUTPUT JACK: This ¼" TS
unbalanced output is pre-EQ, pre-com
-
pression, and pre-mute. It is typically
used to feed an external tuner.
26. HORN LEVEL CONTROL: Use this
L-Pad control to adjust the level of the
high-frequency horn compared to the
woofer level. Adjust it to suit your pref
-
erence.
The horn can be completely turned off
by rotating this control fully counter-
clockwise. (The woofer output level and
frequency range are not affected by this
control.)
