9. EQ+EFX FOOTSWITCH – Connect a two-button footswitch, terminating to a ¼”
TRS connector (Tip = EQ, Ring = EFX) to this jack to control the GEQ and EFX select
switches. The front panel switch is disengaged when the footswitch is plugged in.
10. EFFECTS RETURN LEFT/MONO – Use this ¼” unbalanced jack to return low im-
pedance (600 ohm) signals to the left side amplier from a professional outboard
eects processor. When the amplier is in Mono Bridge mode, this jack feeds the
power amplier input.
11. EFFECTS RETURN RIGHT – Use this ¼” unbalanced jack to return low impedance
(600 ohm) signals to the right side amplier from a professional outboard eects
processor. When the amplier is in Mono Bridge mode, this jack is inactive.
12. EFFECTS SEND MONO – Use this ¼” unbalanced jack to send low impedance (100
ohm) signal, to a professional outboard eects processor such as a reverb, echo,
chorus, anger, or harmonizer device. Output level is approximately 0 dB to +4 dB,
and is post-EQ and post-compression, but is unaected by the master VOLUME
control. You can also use the EFFECTS SEND jack to route signal to an external mix-
ing console or amplier with an input sensitivity of +4 dB.
13. PREAMP OUT LEFT – This output jack is fed from the left preamp (after the eects
return), and may be used with an external power amplier, to connect to a mix-
ing console, or to any other line level device. Use a standard ¼” instrument cable
when connecting to external devices.
14. PREAMP OUT RIGHT – This output jack is fed from the right preamp (after the
eects return), and may be used with an external power amplier, to connect to
a mixing console, or to any other line level device. Use a standard ¼” instrument
cable when connecting to external devices.
15. POWER AMP IN LEFT – This line level input connects directly to the left internal
power amp, and can be used with external preamps, or to connect a CD/MP3
player. Use a standard ¼” instrument cable when connecting devices to this input.
The internal signal path is interrupted when a cable is connected to the POWER
AMP IN jack. When the amplier is in Mono Bridge mode, the POWER AMP IN LEFT
and POWER AMP IN RIGHT jacks mix together for a mono feed to the power ampli-
er input.
16. POWER AMP IN RIGHT – This line level input connects directly to the right inter-
nal power amp and can be used with external preamps, or to connect a CD/MP3
player. Use a standard ¼” instrument cable when connecting devices to this input.
The internal signal path is interrupted when a cable is connected to the POWER
AMP IN jack. When the amplier is in Mono Bridge mode, the POWER AMP IN LEFT
and POWER AMP IN RIGHT jacks mix together for a mono feed to the power ampli-
er input.
17. DIRECT OUT GROUND LIFT Switch – When pressed in (the “GND LIFT” position),
pin 1 is removed from the chassis. This should be used only when a ground loop
hum or buzz is heard. Otherwise, leave it in the out (“NORMAL”) position.
