Introducing the AVALON VT-737SP: A Premium Single-Channel Valve Channel Strip

The AVALON VT-737 SP is an exceptional single-channel valve channel strip renowned for its Class A Circuitry, Opto compressor, and versatile four-band EQ. This high-quality audio equipment has been the go-to choice for countless timeless classics, capable of infusing warmth, sweetness, and vibrancy into even the most lackluster microphones.

One of the standout features of the AVALON VT-737 is its preamp section, which boasts top-tier Class A circuitry. With two cascaded dual vacuum tube triodes meticulously designed to minimize negative feedback and preserve the purity of sound, this preamp guarantees an unparalleled audio experience. It offers three selectable inputs, including Mic level input, Line level input, and DI instrument input. Moreover, the preamp section includes a passive and adjustable high-pass filter, phase polarity control, and a bypass option for added flexibility.

Following the preamp section is the opto-compressor, featuring a ratio control that ranges from 1:1 to 20:1, along with Threshold, attack, and release controls. This opto-compressor utilizes an optical cell for passive attenuation and twin Class A vacuum tubes for precise gain matching. Its minimal signal path ensures pristine signal integrity. Additionally, the compressor can be set to pre- or post-eq using a dedicated switch on the front panel. Notably, the EQ can also be utilized to shape the side-chain path, enabling dynamic spectral shaping techniques such as De-essing. The large VU meter provides the option to display input, output, or gain reduction, while the link Jack input allows for seamless stereo tracking by linking two vt737-SP units together.

The AVALON VT-737SP also incorporates a comprehensive four-band EQ, offering extensive tonal control. This EQ includes Low- and high-shelf filters, as well as two parametric bands. The passive design of the low and high shelves imparts a smooth and pleasing sound, with selectable frequencies for tailored adjustments. The two mid-bands feature variable frequencies and switched Q-width selection for precise sculpting. Additionally, both mid-bands can impact the low and high bands using the X10 frequency multipliers. This EQ is perfect for quick and effective tone enhancement. When in Sidechain mode, the low and high shelves remain in the audio path, allowing for broad sound shaping capabilities.

To ensure an exceptional final output, the AVALON VT-737SP utilizes another dual triode valve to drive the discrete Class-A output amplifier. This meticulous design guarantees exceptional audio quality and faithful reproduction of your recordings.

Experience unparalleled audio performance with the AVALON VT-737SP, the ultimate single-channel valve channel strip that brings your sound to life with warmth, clarity, and sonic richness.
