Peavey Classic VT Series

1. GENERAL DESCRfPTION
Our new VT Series Classic is the latest version of the ever-popuiar tube type Peavey Ciassic, This new
unit has been totaiiy redesigned from input to output, using the iatest circuitry and utiiizing the many design
innovations incorporated into our larger and more powerfui amps. The Aulomix function has been greatiy
simpiified and made even more versatile than the previous system. Newpreamps with tremendously Improved
response and dynamic range have been designed into the new Classic. These preamps are comprised of the
latest high speed integrated circuits which utilize transient protected field effect transistor front ends to
optimize matching to guitar pickups and input dynamic range. Each of the two built-in preamps is voiced
differently with the bright channel having somewhat more high frequency response than the normal channel.
The bright channel features a single input, while the normal channel has both a high gain (A) and a low gain
(B) input. The Automix jack serves asaspeclal inputbetween both channels and includes signal processing of
the bright channel signal which is fed into the normal channel's input through the internal AutomIx
connections. This effectively creates a kind of parrallel/serles arrangement enabling the bright channel to
overdrive the normal channel, the gain control of the bright channel only moderately affecting the overdrive
signal to the normal channel. This arrangement allows both a straight signal from the normal bright channel
and a smooth overdrive signal from the normal channel, with selection being accomplished by use of the
Automix remote footswitch (supplied).
The advanced circuitry features three bands of equalization with a very wide range of variation, thus
enabling the performer to achieve almost any tonality desired. Our extremely effective middle control is able
to create tone colorations to match the sound of most competing units veryclosely. The equalization circuitry
is considerably more effective than that offered by most other manufacturers.
jqe new Classic features a new type of phase circuit that has been bull! into this unit. Because of our
unique phase circuitry, we are able to achieve an extremely wide range of phasing effects, from extremely
subtle colorations to very deep 'swooshing ' characteristic phasing sounds We have designed a new and
versatile oscillator circuit that is capable of modulating the phase effect from very slow and barely perceptible
rates through the normal rates associated with conventional phasors and additionally, up through rates
normally associated with traditional tremolo/vibrato circuits extending to the range normally associated with
some rotating speaker systems. The tremendous range of the phase color and rale controls interact to yield
what we think is the best phase circuit available either as an accessory or built into any amp to date.
The reverb follows the phasor circuitry and is control fable from the remote footswitch. Our new design
utilizes an entirely different type of reverb unit and associated drlvecircuitry and produces an extremely deep
reverb sound. The reverb return circuit has more than adequate gain to allow for various effects. Interesting
sounds can be produced by using a touch of reverb In conjunclion with the built-in phasor which can
approximate the sound of certain rotating speaker systems.
We have included a master gain control to allow overall loudness/gain adjustment as well as to provide
control of the dynamics of the preamp circuit.
2. FRONT PANEL _
2.1. INPUTS
The input consists of four standard phone jacks located at the extreme left-hand side of the front panel,
The bright input jack Is thesingle Input forthe bright channel. Thisjack works in the conventional manner and
connects the signal from your instrument to the input stage of the bright channel The normal channel inputs
consist of a high gam (A) as well as a low gain (B) input to allow fora reduced gain input for handling signals
that tend to overload the high gain (A) input. These two inputs will also permit two instruments to be
connected to the normal channel. The Automix input is connected to the Input of the bright channel whose
output is connected through a signal processing circuit to the input of the normal channel, thus yielding our
unique series/paradel arrangement.
2.2. BRIGHT GAIN CONTROL
The bright gain control determines the sensitivity of the bright channel and in the Automix mode,
determines the amount of clean signal sent to control circuits. It should be noted that the bright channel gain
control can be used to set the overall level from that channel, both in normal operation and when used in the
Automix mode.
2.3. NORMAL GAIN CONTROL
Normal gain control sets the sensitivity of the normal channel and determines how much of the smooth
distortion effed is mixed with the clean signal when in the Automix mode.
It should be noted that the bright and normal gain controls have a definite interplay relationship when in
the Automix mode. Experimentation will illustrate the many subtle changes In dynamics that can be achieved
through manipuialion of these controls.
2.4. EQUALIZATION CONTROLS
The type of equalization used in the VT Series has been researched very thoroughly and we have
designed circuitry that Is extremely versatile. You will find that our equalization settings wifi be somewhat
different than those found on units made by other manufacturers although with proper adjustment, the VT's
tonal circuitry can duplicate the tonality of most any amplifier.
