The Avalon VT-737sp features a combination

of TUBE preamplifiers, opto-compressor,

sweep equalizer, output level and VU

metering in a 2U space. The Avalon VT-737sp

preamplifier has three input selections:

1. Transformer balanced microphone input,

+48v phantom selection. 2. Instrument DI

high source input with jack located on front

panel. 3. Balanced line input, discrete highlevel

Class A. The high-performance

preamplifier utilizes two cascaded, dual

vacuum tube triodes configured with

minimum negative feedback. A high gain

switch boosts the overall gain of the

preamplifier. The four high quality tubes are

configured as singled ended anode coupled

followers. A passive-variable high pass filter

and hard-wire relay bypass completes the

input signal conditioning. The phase reverse

relay is available on all three inputs


The opto-compressor features a minimum

signal path design with twin Class A vacuum

tube triodes for gain matching. The optical

attenuator acts as a simple passive level

controller. Full dynamic control from soft

compression to hard-knee limiting can be

achieved with threshold, ratio-compression,

attack and release controls plus gain reduction

selection on the large VU meter.

Special spectral control including de-ess is

available with the dual sweep mid EQ to

sidechain switch. The EQ section can be

flipped pre or post the opto-compressor via a

front panel switch for alternate effects and

tone shaping. Two VT-737 SP’s can be linked

via a rear panel link cable for stereo tracking.

The compressor bypass is a sealed silver relay

for the most direct signal path


The Avalon VT-737sp equalizer utilizes 100%

discrete, Class A-high-voltage transistors for

optimum sonic performance. The high and

low frequency bands provide the smooth

characteristics of an all passive design, while

the dual mid bands include variable frequency

and switched Q-width selection. The

enhanced range of the mid bands is extended

into the high and low bands by the use of X10

frequency multipliers. The bypass switch

incorporates a sealed silver relay for the most

direct signal path. When the EQ to sidechain

is engaged, the high-low EQ remains in the

audio path for tone enhancement. The output

level control provides a variable control of the

overall signal path. The output amplifier

utilizes another dual triode vacuum tube

driving a 100% discrete, Class A, highcurrent,

balanced and DC coupled low noise

output amplifier.
