Peavey Classic VTX Series User Manual

BACK PANEL
FUSE (R)
The Classics® fuse Is located within the cap of the fuseholder at the extreme left of the rear panel. If the fuse should fail, IT MUST BE
REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGETO THE EQUIPMENT AND TO PREVENT VOIDING
THE WARRANTY. If your Classic® repeatedly blows fuses, It should be taken to a qualified service center for repair.
NOTE
THE FUSE SHOULD ONLY 3E REPLACED WHEN THE CLASSIC’S® POWER CORD HAS BEEN DISCONNECTED FROM
ITS POWER SOURCE.
LINE CORD (S)
For your safety, we have incorporated a three-wire line (mains) cable on the bottom of the chassis with proper grounding facilities. It
is not advisable to remove the ground pin under any circumstances. If it is necessary to use the amp without proper grounding facilities,
suitable grounding adaptors should be used. Much less noise and greatly reduced shock hazard exist when the unit is operated with the
proper grounded receptacles.
GROUND LIFT SWITCH (T)
This switch is the three-position typo with the center (O) position completely removing the internal grounding capacitor from the
circuit. This position is normally recommended for situations where the AC power receptacle is known to contain a properly grounded
third wire. If properly grounded AC mains supply is not available, a suitable ground lift adaptor should be used. The ( ♦ and -) positionsare
used to ground the amplifier properly when only two-wire services are available. One of these positions will yield the lowest amount of
residual hum or '‘popping’' when the instrument is touched
SPEAKER JACKS (U)
A special output transformer allows the Classic® to deliver its full 65 watt RMS output into either a four ohm or a two ohm speaker
load. The internal speaker load from the factory is four ohms and should be plugged into the four ohm jack.
When a four ohm extension cabinet is employed in addition to the internal fourohm load, it should be plupged into the two ohm jack.
The two ohm jack is a switching jack which activates the two ohm tap on the output transformer allowing full power output into both
speaker systems.
When it is desired to use an extension cabinet with an impedance greater than four ohms, it should a Iso be plugged into the two ohm
jack. Power output will be slightly decreased in this mismatched configuration.
SPECIAL NOTE
WE DO NOT RECOMMEND OPERATING THE CLASSIC® INTO LESS THAN A TWO OHM TOTAL LOAD. NO VACUUM
TUBE AMP SHOULD EVER BE OPERATED WITHOUT A LOAD (SPEAKER) ON THE OUTPUT JACKS.
AUTOMIX ™
AUTOMIX ,M is Peavey’s unique control system which allows channel selection and effects £
remote footswitch. NOTE - STANDARD USE OF THE AUTOMIX ™ CIRCUITRY IS TO SELECT
THE LEAD CHANNEL AND A CLEAN SOUND IN THE NORMAL CHANNEL.
AUTOMIX ™ REMOTE SWITCH SOCKET (V)
The remote switch socket is the standard ‘DIN" type and serves as the amp connection for the AUTOMIX ™ remote footswitch. Please
note that the DIN plug hasan indentation that must be mated with the matching indentation in the footswitch receptacle on the rear panel.
This keying action allows the footswitch to be connected only in the proper manner. If the plug is forced or undue pressure is exerted on
the shell or pins, damage could result to the plug or the socket. As with any precision device, reasonable care should be exercised.
PREAMP OUT <X)/POWER AMP IN (W)
To allow "in line’’ patching of various accessories, we have included a system of preamp out'power amp in jacks on the rear panel.
The preamp out is tho straight preamp signal which is the sum cf the outputs of the two channels plus reverb. The output level is
approximately 1 volt RMS and is relatively low (600ohms) impedance The preamp out signal is connected through a switching contact to
the power amp input jack, and normally the preamp out is internally connected to the power amp’s input. This circuit allows basically two
modes of operation When signal is taken from the preamp output, signal is also delivered to the internal power amplifier. If access to the
internal power amplifier is needed or if some accessory device such as a noise gate, delay line, effects device, etc., is to be patched "in
line." then the preamp output signal must be connected to the auxiliary unit's Input, while the auxiliary unit’s output must be connected to
the power amp input with shielded cables, thereby placing the auxiliary unit in series or "in line” with the normal signal path. Additional
booster amp/speaker combinations should be patched using the preamp output. With this unique patching facility, many interesting
effects can be accomplished.
Please note that the power amp input has a sensitivity of 1 volt RMS at an input impedance of 20K ohms. Any device capable of
interface with this impedance and/or lovel should function satisfactorily.
