The VT-737 will energize your recordings!

Avalon VT-737sp Channel Strip at a Glance:
  • Class A preamp design with three input selections
  • Opto-compressor with minimum signal path
  • Sweepable EQ and hardwired bypass

Class A preamp design with three input selections
The VT-737sp has three input selections: First, it features a higher-performance microphone input transformer with 48-volt phantom selection. Second, the VT-737sp offers an instrument DI high-source input with a jack located on front panel. Finally, the VT-737sp includes a balanced line input with discrete high-level Class A circuitry. 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-quality tubes are configured as singled-ended anode coupled followers. A passive/variable high-pass filter and hardwired relay bypass completes the VT-737sp's input signal conditioning. A phase reverse relay is available on all three inputs.

Opto-compressor with minimum signal path
The VT-737sp's 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 VT-737sp's EQ section 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.

Sweepable EQ and hardwired bypass
The 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 VT-737sp's 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, high-current, balanced and DC coupled low noise output amplifier.


Avalon VT-737sp Channel Strip Features:
  • Vacuum tube and discrete design
  • Ideal for DAW and digital recording
  • Wide range of tube tone and control
  • Excellent value for performance
  • Rugged Avalon construction

 Unbelievable Sound on Vocals especially  
by Larry Epstein from Big Apple, January 27, 2008
Music Background:  Engineer- Studio and Live.


“The Vacuum Tube 737 is a great Channel Strip. It's tremendous on Vocals and everything else. I give it an A+. It's built like a tank and built to last. It's undoubtedly the best of all the channel strips and pre's I've tried.”
