SVP-PRO Bass Preamp
The Rear Panel
21. AC LINE IN: Firmly insert the female
end of the AC power cord into this socket.
The grounded power cord should only be
plugged into a grounded power outlet that
meets all applicable electrical codes and is
compatible with the voltage, power and fre-
quency requirements stated on the rear
panel. Do not attempt to defeat the safe-
ty ground connection.
22. AC LINE SELECTOR: Use this switch
to match the unit to the AC line voltage.
23. FOOTSWITCH: Use this jack to con-
nect a two-button footswitch to the preamp
for remote control of the Mute and Graphic
EQ. (Tip controls Mute, ring controls the
Graphic EQ.) The front panel switches
remain active when a footswitch is con-
nected. The front panel Graphic EQ switch
(#13) must be depressed for the footswitch
to control the Graphic EQ.
24. PREAMP OUTS: Use these jacks to
connect the signal from the preamp to your
power amplifier, mixing console or house
PA system.
25. EFFECTS LOOP RETURN: Use this
jack to connect the signal from an external
effects processor to the preamp by means
of a shielded signal cable.
26. EFFECTS LOOP SEND: Use this jack
to connect the signal from the preamp to
the input of an external effects processor
by means of a shielded signal cable.
27. TUNER OUT: Use this jack to connect
the preamp to an external tuner. The signal
at this jack is a direct output from the instru-
ment. This is the only signal which remains
active when the Mute switch (#2) is
depressed.
28. PRE/POST: Use this switch to deter-
mine whether the signal at the Transformer
Balanced Out jack (#29) is pre-EQ (switch
in the out position) or post-EQ (switch
depressed).
29.TRANSFORMER BALANCED OUT:
Use this XLR jack to connect the preamp to
an external power amplifier, mixing console
or house PA system. The signal at this jack
is pre- or post-EQ depending on the setting
of the Pre/Post switch (#28).
