ENGLISH
7. BYPASS SWITCH
Engage/disengage the power amp insert/serial
loop. This switch cannot be programmed.
6. EMULATED LINE OUT
This output sends signal to external equipment.
The signal is taken pre-master volume,
processed through a 4x12 speaker cabinet
emulator and electronically balanced.
Note:
using the line out does not omit the need
for a load to be connected (unless the amp is in
silent recording mode).
5. FOOTSWITCH
Connect the supplied footswitch using any
standard ¼” jack instrument lead.
Note:
using any other type of footswitch rather
than the one supplied will have no effect and
will be ignored by the amp.
14. SPEAKER OUTPUTS
1/4” jack speaker outputs. They are labelled
according to the corresponding cabinet setups:
•
1 x 16 Ohm: connect a 16Ω speaker cab..
•
1 x 8 Ohm / 2 x 16 Ohm: connect a single
8Ω guitar cabinet or two 16Ω cabinets.
•
1 x 4 Ohm / 2 x 8 Ohm: connect a single 4Ω
guitar cabinet or two 8Ω guitar cabinets.
Warning:
although the amplifier has five
speaker outputs, never attempt to connect
more speakers than rated. The safe
combinations are listed above. Any other
speaker configuration may stress or damage
the amp.
