AVALON VT-747 SP TWIN SIGNAL PATH OPTO-COMPRESSOR-EQUALIZER

The Avalon VT-747SP combines a creative STEREO tube-discrete Class A
spectral-opto-compressor with a musical six band program equalizer, L-R
output level and gain reduction metering and internal regulated power supplies
in a 2U space. Ideal for high performance DAW input signal conditioning, stereo
buss compression-EQ, stereo keyboards and analog mastering applications.

SPECTRAL-OPTO-COMPRESSION
The opto-compressor features a minimum signal path design utilizing sealed
silver relays for all signal routing and by pass functions. The optical attenuator
acts as a passive level controller with a Class A, variable gain make-up amplifier.
Full dynamic control from soft compression to hard-knee limiting can be achieved
with master threshold, ratio-compression, attack and release controls. Gain
reduction indication is a large analog VU meter. Low frequency and high frequency
contour parametric spectral controls can be routed into the side-chain path for
enhanced frequency dependent compression with variable frequency and threshold
levels. SC listen provides side-chain listen mode for monitoring.
SIX BAND PROGRAM EQUALIZER
The VT-747SP equalizer utilizes 100% discrete, Class A high-voltage transistors
for optimum sonic performance. The six band STEREO program EQ incorporates
the smooth characteristics of an all passive design. The frequency turnover, Q
and amplitude ranges have been carefully chosen for each band to provide the most
natural harmonic balance and lowest phase change while offering simple and
effective tone control. The EQ can be placed pre or post the opto-compressor for
enhanced effects.
TSP - TWIN SIGNAL PATH
The VT-747SP features TSP which gives you the choice of either tube tone
or the classic, Class A discrete transistor sound by exchanging, three (3)
high-voltage dual triode tubes with discrete amplifiers in the opto-compressor
and primary output stages.
INPUT-OUTPUT and METERING
Fully balanced DC coupled, Class A discrete amplifiers are utilized for the
input and output drive interface with+36dB input headroom. A high quality
analog VU meter indicates accurate gain reduction. Twin 60dB range LED
meters provide fast L-R output status of all levels.
