Who Sells The Cheapest Avalon VT-737sp Class A Mono Tube Channel Strip Limited Edition
Avalon was one of the highest quality brand in market.

In honor of the 10th anniversary of the release of the renowned VT-737sp Class A Mono Tube Channel Strip, Avalon has produced a special "Blackface" model. The VT-737SP features a combination of TUBE preamplifiers, opto-compressor, sweep equalizer, output level and VU metering in a 2U space. The VT737SP Anniversary is identical in terms of circuitry, the only difference being cosmetic; the front panel is matte-black and the original orange LEDs have been replaced with cool blue ones.PREAMPLIFIERThe VT-737SP has three input selections:1. The VT-737SP features a higher-performance microphone input transformer with +48v phantom selection.2. Instrument DI high source input with jack located on front panel.3. Balanced line input, discrete high-level Class A.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 hardwire relay bypass completes the input signal conditioning. The phase reverse relay is available on all three inputs.OPTO-COMPRESSONThe 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 sidechain switch. The 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.SWEEP-EQUALIZER AND OUTPUT LEVELCl
