Q. UNBALANCED LINE OUT—
Provides unbalanced preamp
output for an auxiliary amplifier or sound equipment that
includes the effects loop signal. Output level is controlled
by MASTER Volume {C}. DIRECT/LINE and PAD {S} also
affect this output.
R. TUNER OUT—
Plug in your bass guitar tuner here to
enable inline tuning. Use MUTE {B} to disable audio out-
put while tuning.
S. BALANCED (XLR) OUTPUT—
A true electronically bal-
anced output, suitable for studio and “front-of-house”
(live) mixing consoles. The function of each of the three
BALANCED OUTPUT switches are described below. Wiring
for this jack is the "American Standard."
DIRECT /
LINE—
Connects the BALANCED OUTPUT
and UNBALANCED LINE OUT jacks to the signal path
before (DIRECT) or after (LINE) the onboard tone shap-
ing and MASTER volume circuits.
GROUND /
LIFT—
Disconnects the BALANCED
OUTPUT ground connection (LIFT) which may reduce
hum noise due to a ground loop (non-standard XLR
wiring). Normally leave this switch out (GROUND).
NOTE: Lifting the ground connection will not solve
hum noise due to bad cables, poor connections,
miswired A/C outlets, nearby fluorescent lighting
(especially with single-coil pickups) or a cell phone in
your pocket.
0dB /
–10dB—
Reduces the BALANCED OUTPUT
and UNBALANCED LINE OUT levels by –10dB. Normally
leave this switch out (0dB).
