Avalon VT-737sp Preamp Class A Mono Tube Channel Strip
Avalon VT-737sp Preamp - Class A Mono Tube Channel Strip. Circuit topology Four dual triode vacuum tubes (Sovtek 6922), high-voltage discrete Class A. Gain Range Microphone: Transformer balanced 850/2500 ohm, 0dB to +58dB Instrument.

Maximum output level +30dB balanced 600 ohms, DC coupled, discrete Class A. Instrument+30dB unbalanced front panel jack socket. The Avalon VT-737sp Class A Mono Tube Channel Strip features a combination of TUBE preamplifiers, opto-compressor, sweep equalizer, output level and VU metering in a 2U space.

Instrument DI high source input with jack located on front panel. Balanced line input, discrete high-level Class A. 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 hardwire relay bypass completes the input signal conditioning. The phase reverse relay is available on all three inputs. OPTO-COMPRESSON 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.
