OPERATING GUIDE
The new Peavey Mark III Musician represents the fourth generation of this series which has proven to be one of the most popular ever
introduced to the musical market. The Mark III Series brings our many years of manufacturing and playing experience together in a
totally
redesigned electronics chassis and package. Much engineering time has been devoted to all the minute details that combine to create an
effective instrument amplifier capable of producing the various dynamics, harmonics and tonal textures so vital in contemporary music.
Particular care has been exercised in the design of our preamp and equalization circuitry. The Musician preamp features Peavey's exclusive
pre and post gain controls enabling total control over the dynamics and gain of each input preamplifier. The pre gain control functions as the
normal gain control, w/hile the post gain control operates as individual "master controls" for each channel. This feature is.tremendously
important when using the Musician in the AUTOMIX mode. The relatively weak guitar pickups of ten years ago have given way to the new
generation pickups that feature extremely high output and require absolute maximum performance from the amplifier's signal processing
circuitry. Our efforts to satisfy the demand for the proper "texture" and overload characteristics have made it necessary for Peavey to
completely and totally redesign the electronic circuitry from the input jack through to the output jack.
To further complement this "all new" unit, we have designed a totally new series of color-coded knobs that not only provide function
identification by color, but also feature greatly improved visibility and "touch indexing" capability.
The Mark III Musician utilizes the latest BI-FET and CMOS devices to enable signal processing and features that would have been
totally "out of reach" for all but the most sophisticated recording studios just a short time ago. Totally new circuitry utilizing the latest
advances In semiconductors and design techniques provide the versatility built into the new Musician. Our exclusive AUTOMIX function has
been made considerably simpler and more efficient using LED indicators, combined with active CMOS analog switches. Each channel of the
Musician is voiced slightly differently, with Channel A having active equalization, while Channel B offers passive equalization. Each channel
features an equalizer assign switch to enable "pre-programming", either through or around the six-band graphic equalizer. These equalizer
assign switches are extremely effective when using the AUTOMIX feature of the amplifier since they allow one channel to be routed through
the graphic, with the other channel routed around the graphic, thus yielding a tremendous tonal variation when switching from channel to
channel. Our new phasor circuit utilizes new engineering techniques that avoid the many problems associated with the older FET-based
designs and the phasing effect and the timing oscillator circuitry combine to form what we feel is the most effective phasing unit ever
incorporated into a musical instrument amplification system. The reverberation unit is driven by a fully complementary circuit that uses the
reverb coil Itself in the feedback loop to electronically maximize the performance of the Hammond Type IV delay line. The Musician also
features a complete and versatile patching facility capabie of driving any known power amplifier or line level effects device. This patch panel
includes stereo capability with the outputs from Channel A and B brought out separately, as well as a specially compensated line output that
delivers a signal that closely matches what is heard from the amplifier's speaker system, making effective direct patching into mixers, etc.,
practical for the first time.. Each output is capable of driving 600-Ohm loads to better than 2-Volt levels.
The power output section of the Mark III Musician is based on eight high-voltage, ultra-fast output devices bolted to a massive aluminum
heatsink. This power section also includes a built-in matching transformer to allow optimum performance with either 8- or 4-Ohm loads and
includes adequate capabilities to effectively drive loads as low as 2 Ohms. Reduced damping factor assures tube-type overload qualities
and tonal color.
Overall, the Musician represents one of the most sophisticated musical instrument amplifiers ever made and represents what we feel is
a quantum jump in musical instrument amplifier technology. Experimentation with the many features of this new unit and comparison with
other units will illustrate the many advantages of this new Mark III Series amplifier.
