This exciting new guitar amplifier design offers dynamic versatility from its user friendly analog topol-

ogy. The focal point of the most sought after tone in guitar amplification is the character and warmth

of the 12AX7 tube. Our INTERGRATED VALVE AUGMENTED CIRCUITRY utilizes the tube (valve)

as the center point in the design and enhances its tone with unique circuits that shape the tonality,

gain and saturation. The result is a highly versa- tile guitar amplifier with traditional analog knobs that

allow the performer to use the amp as an extension of the instrument.

The 5 gain stages in the preamp are coupled to our high-output 65 waft solid-state amplifier design

that features true high-fidelity audio reproduction and include complete short circuit, VI limiting over-

load curves and precise thermal tracking protection. A patented “SPIKE" thermal management sys-

tem is built into the power transistor, providing an elegant form of management and protection of all

vital amplifier parameters.

This amplifier is rated at a “real world” 65 watts RMS @ 4 ohms but with dynamic headroom in ex-

cess of I 00 watts! The complete design and features combine to make the IVAC an uncompromising

guitar amplification system.

FEATURES AND OPERATION OVERVIEW:

INPUT - The IVAC-65 is equipped with a standard 1/4” input. The input impedance is approximately

500k ohms, which we determined provides the best response from all pickups currently available. An

added benefit of this 500k impedance is the smoothness of the tonal response, consistency of sus-

tain and an overall reduction of noise. Additionally, the precision input scaling preamp contains a 40

Hz, 12 dB/octave high pass filter (more effective and less intrusive than the more common 6 dB fil-

ters) and an “RFI” filter (radio frequency interference) to eliminate bleed-through from those pesky

DJ's and truckers.

CLEAN CHANNEL -The IVAC-65's clean channel is constructed using a monolithic FET amplifier for

a clean, sweet, non-distorted sound. The tone is natural and open, lending itself readily to any musi-

cal style. The CLEAN GAIN control uses “loop feedback" style circuitry for wide dynamic range and

an exceptionally low noise floor. Whether playing soft or hard, the responsiveness of the clean pre-

amp is punchy and articulate, with a big bottom end that is not muddy or overpowering. Mixing this

signal with the overdrive channel will give the player endless possibilities.
