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.
