16 AC Socket
Connect an AC cord here.
CAUTION: Ensure you use an intact AC cord with an insulated plug only!
Before you power the amp up, ensure the voltage value printed beside the
AC socket corresponds to the available current.
17 AC Fuse Box
Contains mains fuse (rear chamber) and spare fuse (front chamber).
NOTE: Ensure replacement fuses bear identical ratings (refer to the table)!
18 Footswitch Ultra Gain; Master A - B
Stereo jack designed to take a dual footswitch for the following functions:
1. To switch back and forth between Normal Gain and Ultra Gain modes (mono terminal).
2. To switch back and forth between the master A and B knobs (stereo terminal)
Note that when you connect a footswitch to this jack, the master A/B switching option is reassigned to
the footswitch, allowing you to activate the volume level of each knob irrespective of mode (Normal or
Ultra Gain).
19 F.X. Loop Send
Signal output for the Effects loop. Connect this output to a signal processor’s
input/return jack via a shielded cable with 1/4" plugs.
20 F.X. Loop Return
Signal input for the Effects loop. Connect this input to a signal processor’s
output/send jack via a shielded cable with 1/4" plugs.
21 Balance
FX mix control for the Effects loop: Rotate the knob to the "DRY" position for the pure
amp signal, i.e. no effect on the signal. Turn clockwise to blend in an effect connected to the loop
to the dry signal (parallel/passive). At the "EFFECT" position, only the wet signal, i.e. the signal
sent from the FX device is fed to the power amp (serial/passive).
NOTE: If no effects processor is connected to this loop, leave this control in the "DRY" position!
22, 23 Poweramp Output 8 ohms parallel:
Parallel 8-ohm speaker outs, connected internally in parallel. Connect an 8-ohm cabinet here.
Alternatively, two 16-ohm cabinets can also be connected to these two outputs.
24 Poweramp Output 16 ohms serial:
16-ohm speaker out, connected internally in series with Jack 25. Connect a 16-ohm cabinet here. Two
8-ohm speakers are connected to Jacks 24 and 25.
CAUTION: If you intend to use a 16-ohm cabinet only, make absolutely certain you
connect it to Jack 24. Jack 25 is only enabled when a speaker is connected to jack 24.
25 Poweramp Output 16 ohms serial:
16 ohms serial. This is an auxiliary output connected in series with Jack 24. This jack is designed for one
application for only—when you are driving a combination of two 8-ohm cabinets/speakers. This output
may only be used when an 8-ohm speaker is connected to Jack 24. (See the example for Item 24)
NOTE: Never operate the amplifier without a sufficient load, otherwise you may damage or destroy
the power amp! Ensure your cabinet’s specifications match the respective output’s specs.
Possible speaker combinations:
1 x 8 ohms or 2 x 16 ohms (Jacks 22 and 23) or
1 x 16 ohms (Jack 24!) or 2 x 8 ohms (Jacks 24 and 25).
