the avalon vt-737sp features a combination of tube pre-amplifiers, opto-compressor, sweep e, output level and vu metering in a 2u space.
preamplifier
the vt-737sp has three input selections: 1. the vt-737sp
features a higher-performance microphone input transformer with
+48v phantom selection. 2. instrument di high source input with
jack located on front panel. 3. balanced line input, discrete
high-level class a. the class a 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 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.
opto-compressor
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 side-chain switch. the e can be
flipped pre or post the opto-compressor via a front panel switch
for alternate effects and tone shaping. two vt-737sps 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.
sweep-e and output level
the vt-737sp e utilizes 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 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 e 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
discrete, class a, high-current, balanced and dc coupled low noise
output amplifier.
avalon vt-737sp features
vacuum tube triode signal path, transformer balanced microphone
input, high-voltage circuits for maximum headroom to +30db, low
noise -92db, internal discrete power supply with toroidal
transformer, soft-start tube life extender, stereo link for
compressors, all discrete class a e with musical passive
filter design, sealed silver relays for signal routing, large
control knobs with professional conductive plastic potentiometers,
vu meter for output level monitoring and compressor gain
reduction.
