Back Panel - Control knobs
•
Edge
The Edge control is global; it affects both channels.
Adjusting this clockwise will add high mid/treble to the sound.
•
Fat
The Fat control is also global; it affects both channels.
Adjusting this clockwise will add low mid/bass to the sound.
•
Mix
Mix control for the F/X loop. When set full counter clockwise at the 10% mark,
the loop is in parallel. Only a small amount of the connected effect pedal/rack
unit in the send/return jack sockets will be mixed in the dry signal.
By turning the Mix knob more towards the 100% mark the F/X loop becomes
more serial. When turned fully clockwise, to the 100% mark, the F/X loop is in
serial mode.
The F/X loop is designed to suit both stomp boxes and rack units and operates
at -10 dB level. The F/X loop is active on both channels.
Foot switch jack sockets
Connect the foot switch plugs marked 1 and 2 to the jack sockets respectively.
The foot switch jack sockets can also be operated from a Patch bay/ MIDI switcher.
This allows all the foot switch functions to be managed by a MIDI operated unit.
Mains input
Always connect the mains to an earthed outlet with a 3 pole CE approved mains cord.
Fuse
Replace broken fuse only with the same type of slow blow fuse - voltage/current.
Note:
Never operate the amplifier without a connected speaker
since this can cause severe damage to the amplifier.
