(27) Fuse
A fuse is located within the cap of the fuse holder. This fuse must be replaced with one of the same type and value
to avoid damaging the amplifier and voiding the warranty. If the amp repeatedly blows the fuse, it should be taken
to a qualified service center for repair.
Warning: The fuse should only be replaced after the power cord has been disconnected.
(28) Ground Polarity Switch
This three-position, rocker-type switch should normally be placed in the center (0) position. If hum or noise is
noticed coming from the speaker enclosure(s), the switch may be placed in the “+” or “-” position to minimize
hum/noise. If changing the polarity does not alleviate the problem, consult your authorized Peavey dealer, the
Peavey factory or a qualified service technician.
(29) Remote Switch (Triple XXX
®
40 only)
This 1/4" connector is provided for the connection of the remote footswitch. The footswitch cable should be
connected before the amp is powered up. See the FOOTSWITCH section of this manual for explanation of switch
operation.
(30) Speaker Output
This 1/4" mono (TS) jacks is provided for the connection of speaker enclosure(s). Minimum speaker impedance is 16 ohms.
(31) Damping Switch
This 3-position switch allows adjustment of the amplifier’s damping factor. Damping is the ability of an amplifier to
control speaker cone motion after a signal disappears. A high damping factor (TIGHT) reduces cone vibration
quicker than a low (LOOSE) factor. This switch works much like the resonance and presence controls on other
Peavey amps, if those controls were turned simultaneously. If the DAMPING SWITCH is changed, the volume of
the amp will also change and require re-adjustment.
(32/33) Effects Send/Return
These
1
⁄4" mono (TS) jacks allow signal to be sent to‚ and returned from‚ external effects and/or signal processors.
Using shielded cables with
1
⁄4" mono (TS) phone plugs, patch from EFFECTS SEND to the input of the external
device and from the output of the external device to EFFECTS RETURN. Only devices that do not increase signal
gain should be used in this effects loop (chorus, delay, reverb, etc.).
(34) Remote Switch (Triple XXX
®
40 EFX only)
This seven-pin DIN connector is provided for the connection of the remote footswitch. The footswitch cable
should be connected before the amp is powered up. See the FOOTSWITCH section of this manual for explanation
of switch operation.
