8. Standby
This switch enables the operation of the speaker output. For silent recording or
practice this switch should be put in the standby position. This will disable the
speaker output, but the emulated output will continue to work.
9. Power
This switch is used to turn the amplifier on and off. You should always turn this
switch on before turning on the Standby switch (8).
Rear Panel
1. Mains Fuse
The value of the Mains Fuse is specified on the rear panel. Never use a fuse of the
incorrect value or attempt to bypass it.
2. Mains Input
The supplied detachable mains lead is connected here. The lead should only
be connected to a power outlet that is compatible with the voltage, power and
frequency requirements stated on the rear panel. If in doubt get advice from a
qualified technician.
3. H.T. Fuse
The value of the H.T. Fuse is specified on the rear panel. Never use a fuse of the
incorrect value or attempt to bypass it.
4. Speaker Outputs
The output marked '1x16 Ohm' is for the connection of a single 16 Ohm extension
speaker cabinet (or the internal loudspeaker of the Series One 10 AE combo).
The outputs marked '1x8 Ohm or 2x16 Ohm' are for the connection of either a single
8 Ohm extension cabinet or two 16 Ohm cabinets. Also, the internal loudspeaker
of the Series One 10 AE combo can be plugged in here if it is used with a 16 Ohm
extension cabinet. See table below.
Internal 16 Ohm combo speaker
Internal 16 Ohm combo speaker
plus one 16 Ohm extension cab
One 16 Ohm extension cabinet
Two 16 Ohm extension cabinets
Single 8 Ohm extension cabinet
WARNING: The output marked '1x16 Ohm' should never be used at the same
time as any of the outputs marked '1x8 Ohm or 2x16 Ohm'. Failure to correctly
match the impedance of the amplifier and speakers will damage the amplifier.
