21. FOOTSWITCH: Use this jack to connect a two button footswitch for
remote Mute and EQ On/Off control. (Tip = Mute, ring = EQ On/Off.) When
a footswitch is connected, the Mute switch (#3) remains active; however,
the Graphic EQ switch (#12) is disabled.
22. PREAMP OUTPUT: This jack is a direct preamp output for use with
external power amplifiers, mixing boards, external effects, etc. Connect the
external unit’s input to this jack by means of a shielded signal cable.
23. POWER AMP INPUT: This jack connects directly to the power amp for
use with an external preamp. When using an external source, connect its
output to this jack by means of a shielded signal cable to feed the signal
into the power amp section. The amplifier’s input signal is disconnected
when a plug is inserted into this jack.
24. SPEAKER OUTPUTS: The 1/4” jacks offer a convenient method of
connecting to speaker cabinets using cables terminated with 1/4” plugs.
However, when using the amplifier at or near its full output power, using the
Speakon
®
jacks is recommended. (Pin 1+ = hot, pin 1- = return.)
NOTE: This amp is internally hard wired for bridge mode operation. Do not
remove the insulating washers from the 1/4” Speaker Output jacks.
Removing the insulating washers will damage the amplifier and void your
warranty.
25. TUNER OUT: Use this jack to connect the amplifier to an electronic
tuner. The signal at this jack is always “live,” even when the Mute switch
(#3) is engaged, allowing for “silent tuning” as well as a monitor feed which
remains active when the house mix is muted.
26. EFFECTS LOOP SEND: Use this jack to sent a signal to the input of
an external effect by means of a shielded signal cable.
27. EFFECTS LOOP RETURN: Use this jack to connect the output signal
from an external effect to the amplifier by means of a shielded signal cable.
28. LINE OUT UNBALANCED: Use this 1/4” jack to send an unbalanced
line level signal to a house mixing board, recording console, or external
amplifier. The signal level at this jack is controlled by the Line Out Level
control (#32) and may be Pre or Post-EQ depending on the setting of the
Line Out Pre/Post switch (#31).
29. LINE OUT BALANCED: Use this XLR jack to send a balanced line
level signal to a house mixing board, recording console, or external ampli-
fier. The signal level at this jack is controlled by the Line Out Level control
(#32) and may be Pre or Post-EQ depending on the setting of the Line Out
Pre/Post switch (#31).
30. LINE OUT GROUND LIFT: This switch, when depressed, disconnects
the ground connection at the Balanced Line Out jack (#29). This may help
reduce residual hum and buzz sometimes picked up in line out signal
cables.
31. LINE OUT PRE/POST: This switch, when depressed, sends a Post-
EQ signal to the Line Out jacks (#28,29). The Post-EQ signal is modified
by the settings of the tone controls, Graphic Eq and effects loop. With the
switch in the out position, the signal sent to the Line Out jacks is Pre-EQ.
The Pre-EQ signal is a direct output and is not affected by any of the pre-
amp settings.
32. LINE OUT LEVEL: Use this control to adjust the signal level at the Line
Out jacks (#28,29). This control works independently from the Master con-
trol (#14).
33. AC LINE IN: Firmly insert the supplied AC power cord into this socket
until it is fully seated. This grounded power cord is to be plugged into a
grounded power outlet, wired to current electric codes and compatible with
voltage, power, and frequency requirements stated on the rear panel. Do
no attempt to defeat the safety ground connection.
34. CIRCUIT BREAKER: The SVT1000 employs an AC line circuit break-
er to help protect against damage due to excessive current demands. If the
amplifier stops working, check the circuit breaker. If it has opened, the but-
ton will be protruding and showing a contrasting color. You can reset the
circuit breaker by pushing it in until it latches. The breaker must cool down
for a short time before the button will latch. If the circuit breaker opens
repeatedly, have the amplifier checked by a qualified service person.
IMPORTANT NOTE: This unit employs forced air cooling by
means of an internal fan system. The front and rear ventilation
slots must remain unobstructed when operating this amplifier.
