Peavey Triple XXX Operating Manual page 7

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.
(23) CABINET IMPEDANCE SWITCH
This three-position switch allows appropriate selection of speaker cabinet impedance. If two
enclosures of equal impedance are used, the switch should be set to half the individual value.
For example, two 16-Ohm enclosures necessitate an 8-Ohm setting, while two 8-Ohm
enclosures would require a 4-Ohm setting. Minimum speaker impedance is 4 Ohms.
(24) SPEAKER OUTPUTS
These paralleled 1/4" mono (TS) jacks are provided for the connection of speaker
enclosure(s). Again, minimum speaker impedance is 4 Ohms. The CABINET IMPEDANCE
SWITCH (23) should be set to match the load of the speaker cabinet(s).
(25) LINE OUT LEVEL
This control sets the level of signal being sent out of the LINE OUT (26) jack. It may be used
to balance the level of slave power amp/speaker systems driven from the LINE OUT (26) to
the level of cabinets driven from the SPEAKER OUTPUTS (24).
(26) LINE OUT
This 1/4" mono (TS) jack provides a post-power amp signal to drive another power
amp/speaker system while maintaining the amplifier's tone.
(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) IEC MAINS CONNECTOR
This is a standard IEC power connector. An AC mains cord having the appropriate AC plug
and ratings for the intended operating voltage is included in the carton. The mains cord
should be connected to the amplifier before connecting to a suitable AC outlet.
U.S DOMESTIC AC MAINS CORD
The mains cord supplied with the unit is a heavy-duty, 3-conductor type with a conventional
120 VAC plug with ground pin. If the outlet used does not have a ground pin, a suitable
grounding adapter should be used, and the third wire should be grounded properly.
Never break off the ground pin on any equipment. It is provided for your safety.
