21.AC LINE IN: Firmly insert the supplied AC
power cord into this socket until it is fully seated.
Plug the male end of the cord into a grounded AC
outlet. DO NOT DEFEAT THE GROUND PRONG
OF THE AC PLUG!
22.AC LINE SELECTOR: This switch selects the
proper AC line voltage to match the preamp to the
available AC mains. Make sure it is in the proper
position.
23.FOOTSWITCH: This is a stereo jack which
will operate with a standard dual footswitch. The tip
of the plug controls the Mute operation, the ring
controls the Graphic EQ operation, and the sleeve
acts as a ground common to both. With the
footswitch inserted, both the front panel and the
footswitch Mute switches are active. The front
panel Graphic EQ switch (13) must be depressed
for the Graphic EQ foot-switch to operate.24.PREAMPOUTS: These jacks carry the post-
Master (18) signal. This signal is the main output
which can be used to feed an external power
amplifier, mixing console, or house PAsystem.
25.EFFECTS LOOPRETURN: This is a pre-
Master (18) patch point return jack. It breaks the
path through the preamp. When using an external
signal processor, connect this jack to the OUTPUT
of the processor by means of a shielded instru-
ment cable.
26.EFFECTS LOOPSEND: This is a post-EQ,
pre-Master (18) patch point send jack. It does not
break the path through the preamp. When using an
external signal processor, connect this jack to the
INPUTof the processor by means of a shielded
instrument cable.27.LEVEL: This control adjusts the level of the
signal at the Balanced Out jack (29).
28.PRE/POST:This switch selects a direct out
from the bass (Pre) in the OUTposition and the
preamp signal just before the Master (18) (Post) in
the depressed position. The selected signal is sent
to the Balanced Out jack (29).
29.TRANSFORMER BALANCED OUT: T h i s
XLR-type jack is the output for the signal selected
by the Pre/Post switch (28). This signal can be
used to feed an external power amplifier, mixing
console, or house PAsystem.
30.TUNER OUT:This jack is a direct output from
the instrument. It is the only output that stays
active when the Mute switch is depressed.16
