15. AC LINE IN: Firmly insert the
female end of the supplied 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 freqency requirements
stated on the rear panel.
16. FOOTSWITCH: Use this jack to
connect the mono plug of a single but-
ton footswitch for remote control of the
Mute function.
17. PREAMP OUTPUT: Use these
jacks to send the output signal to the
input jacks of your power amplifier.
18. PRE/POST: Use this switch to
select either a Pre or Post EQ signal at
the Line Output jack (#20). When this
switch is depressed, the signal is Post
EQ and is affected by the settings of
the front panel tone controls. With this
switch in the out position the signal is
Pre EQ, taken directly after the first
tube stage.
19. GND LIFT/GND: When this switch
is in the out position, the chassis
ground at the Line Output jack (#20) is
electronically disconnected. This helps
reduce hum in the Line Output signal.
20. TRANSFORMER BALANCED LINE
OUTPUT: Use this jack to send a line
level signal from the preamp to a
house mixing board, recording con-
sole, or external amplifier.
21. TUNER OUTPUT: Use this jack to
send a signal to an electronic tuner.
When the Mute function is engaged
(#3, #16), the signal at this jack is unaf-
fected and remains present, allowing
for silent tuning during a performance.
