7. Impedance Selector
This control matches the amplifier's impedance to that of the connected speakers.
Always ensure that the selected impedance matches that of the speaker cabinets
connected. See table below.
Cabinets Connected Impedance Selected
1 x 16 Ohm cabinet 16 Ohms
2 x 16 Ohm cabinets 8 Ohms
1 x 8 Ohm cabinet 8 Ohms
2 x 8 Ohm cabinets 4 Ohms
1 x 4 Ohm cabinet 4 Ohms
A speaker cabinet of less than 4 Ohms, or 2 x 4 Ohm cabinets, should not be used
together with this amplifier.
WARNING: The amplifier must always be completely powered down before
adjusting the setting of the Impedance Selector. Failure to do this, or to correctly
match the impedance of the amplifier and speakers, will damage the amplifier.
8. Speaker Outputs
There are two parallel speaker outputs for connecting external speaker cabinets.
When connecting speakers always ensure that the Impedance Selector (7) is set
correctly.
9. Speaker Emulated Output
This output emulates the tonal characteristics of a guitar speaker cabinet and
provides a natural valve overdrive tone for connection to a recording device or mixing
desk. Always use a good quality screened lead. There is both a jack and a balanced
XLR output.
NOTE: To 'silently' record, turn the amp to standby mode. You may also record from
this output while in standby mode without a loudspeaker connected, but ensure that
no loudspeaker leads are connected to either of the loudspeaker output jack sockets
of the amplifier, as this will defeat the load protection circuit and cause damage to
the amplifier.
10. Effects Loop Level
The Effects Loop Level switch sets the effects loop to either +4dBV/-10dBV, which
enables you to use it with either professional equipment (+4dBV setting), or with
guitar level effects such as effects pedals (-10dBV setting).
11. Effects Loop Return
Connect the (mono) output of an external effects unit here.
12. Effects Loop Send
Connect the (mono) input of an external effects unit here.
