The Avalon Design VT-737sp is a premium channel strip that brings together a Class A vacuum tube microphone preamplifier, opto-compressor, sweepable EQ, and output level control, all within a single 2U rackmount unit. Designed to deliver pristine signal path integrity and musical character, the Avalon Design VT-737sp is widely respected in professional studios for both vocal and instrument recording.
At the input stage, the Avalon Design VT-737sp features a high-performance Class A tube preamp using hand-selected dual triode valves for low-noise, high-gain operation. It accommodates microphone, line, and instrument-level signals, and includes a dedicated DI input on the front panel with high impedance for optimal instrument matching.
The optical compressor offers smooth dynamic control with attack and release timing options, while maintaining the transparency and warmth that opto compression is known for. The EQ section is equally versatile, providing four bands of fully sweepable frequency control with the option to reconfigure the signal path, placing the EQ before or after the compressor.
Built to meticulous standards, the Avalon Design VT-737sp combines discrete electronics, silver-plated circuit boards, custom-toroidal transformers, and high-quality components throughout. It has earned its reputation in top-tier studios worldwide, with many engineers and producers favouring it for its rich tonal shaping, clarity, and versatility across a wide range of sources.
