Rear Panel Facilities
PEACEMAKER 20, 40, 60 COMBO & PEACEMAKER 60 HEAD
MAINS INLET SOCKET
This is the mains power inlet to the amplifier. Make sure that this is connected to the correct voltage
supply.
This also carries the power inlet FUSE. If this should ever need replacing be sure to use the correct rating
and type as marked on the rear panel of the unit.
MASTER FOOT-SWITCH SOCKET (Peacemaker 40 & 60 ONLY)
This is a jack socket for connecting a suitable foot-switch to allow switching between the MASTER 1 &
MASTER 2 volume controls.
CHANNEL 1, 2 & 3 FOOT-SWITCH SOCKET
This is a stereo jack socket for connecting a double foot-switch to allow switching between Channel 1 &
Channel 2 and also for switching in the gain boost for Channel 3.
EFFECTS MIX CONTROL
The EFFECTS LOOP on these amplifiers is a parallel loop that allows a degree of effects signal to be mixed in
with the main guitar signal.This control is used to set the level of effects signal returned to the signal path.
EFFECTS SEND
This is the jack connection to your effects device from the amplifier.
EFFECTS RETURN
This is the jack connection from your effects device back into the amplifier.
EXTERNAL SPEAKER 8 OHMS (Peacemaker 40 & 60 ONLY)
This is an external speaker socket for connecting to an 8 Ohm speaker such as a 2x12 cabinet (normally 8
Ohms).This socket is in parallel with the internal speaker socket.
INTERNAL SPEAKER 8 OHMS (Peacemaker 40 & 60 ONLY)
This is the socket for connection to the internal 8 Ohm speaker.
IMPEDANCE SELECT SWITCH (Peacemaker 40 & 60 ONLY)
This is used to select the desired output impedance of the amplifier.
DEDICATED EXTERNAL 16 OHM SPEAKER SOCKET
This socket can be used for plugging the amplifier into any 16 Ohm speaker, such as a 4x12 cabinet.
IMPEDANCE SELECTION ADVICE
It is important to ensure the correct impedance is selected for the load presented to
the amplifier. Failure to do so could cause damage to the amplifier.
Never run the amplifier without a speaker connected as this will damage the output
transformer.
PEACEMAKER 20 COMBO
If you wish to run the combo into an external cabinet, you must use a 16 Ohm cabinet. Please note that
plugging a speaker into this socket will automatically disengage the internal speaker.
PEACEMAKER 40 / 60 COMBO
The interal speakers on both combos present a load of 8 Ohms.When used without an extension speaker,
leave the impedance selector at 8 Ohms.
If you wish to use an 8 Ohm extension speaker cabinet, plug it into the 8 Ohm external speaker socket
and switch the impedance selector to 4 Ohms.
If you wish to use a 16 Ohm extension speaker (e.g. a 4x12 cabinet) you should plug this into the
dedicated 16 Ohm external speaker socket. Using this socket does not affect the matching of the internal
speaker, so you should leave the impedance selector at 8 Ohms.
If you wish to use both an 8 Ohm and a 16 Ohm external speaker cabinet, connect each cabinet to its
appropriate socket and set the impedance selector at 4 Ohms.
PEACEMAKER 60 HEAD
For use with one 8 Ohm cabinet, plug it into either of the 8 Ohm sockets and set the selector to 8 Ohms.
For use with two 8 Ohm cabinets, plug them into the 8 Ohm sockets and set the selector to 4 Ohms.
For use with a 16 Ohm cabinet, plug it into the 16 Ohm dedicated external speaker socket. It does not
matter how you set the impedance selector, unless you are also using one or two 8 Ohm cabinets, in
which case you should set the selector as described above.
