Class A Circuitry for Superior Sound Quality
The Avalon VT-737 SP features high-level Class A circuitry with minimal negative feedback, ensuring a pristine and pure sound by reducing distortions and enhancing audio clarity.
The Avalon VT-737 SP is a single-channel valve channel strip with Class A Circuitry, Opto compressor and sweepable four-band EQ.
The Avalon VT-737 has been the channel strip of choice on countless classics for its ability to add warmth, sweetness and vibrancy to even the dullest of microphones.
The preamp section includes high-level Class A circuitry with two cascaded dual vacuum tube triodes designed to provide minimal negative feedback and retains a purer sound. Three inputs can be selected from Mic level input, Line level input and DI instrument input. The preamp section also includes a passive and variable high-pass filter, phase polarity and bypass.
This is followed by an opto-compressor with a ratio control ranging from 1:1 to 20:1, Threshold, attack and release controls. The Opto compressor uses an optical cell for passive attenuation and twin Class A vacuum tubes for gain matching, all in a minimal signal path to keep the signal as pure as possible. The compressor can be set to pre- or post-eq via a dedicated switch on the front panel. The EQ can also be employed to shape the side-chain path offering dynamic spectral shaping capabilities such as De-essing. The large VU meter can be made to display input, output or gain reduction. A link Jack input can be used to link two vt737-SP together for stereo tracking.
Finally, a four-band EQ is provided including Low- and high-shelf and two parametric bands. Both Low and high-shelves use passive designs offering a smooth sound with selectable frequencies. The two mid-bands include variable frequencies with a switched Q-width selection. Both mid-bands can also affect low and high bands thanks to the X10 frequency multipliers. The EQ is ideal for quick and tone enhancement. while in Sidechain mode, both Low and high shelves remain in the audio path to offer broad sound shaping.
The final output stage uses another dual triode valve to drive the discrete Class-A output amplifier.

PRODUCT VIDEOS
“My signal chain is normally a Neumann 87 or 67 going into an Avalon 737. I love the way the Avalon preamp sounds with his (Jay-Z) voice. It’s a perfect match. I use the 737 compressor as well as the preamp.”
