Multi-featured unit with tube microphone\/instrument preamplifier, opto-compressor, and sweep equalizer.\u003c\/p\u003e\n\u003cp\u003eThe\u003cstrong\u003e Avalon VT-737SP\u003c\/strong\u003e features a combination of tube preamplifiers,  opto-compressor, sweep equalizer, output level and VU metering in a 2U  space.\u003cbr\u003e\u003cbr\u003ePREAMPLIFIER \u003cbr\u003eThe 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 hard-wire relay  bypass completes the input signal conditioning. The phase reverse relay  is available on all three inputs.\u003cbr\u003e\u003cbr\u003eOPTO-COMPRESSOR \u003cbr\u003eThe  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  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.\u003cbr\u003e\u003cbr\u003eSWEEP-EQUALIZER AND OUTPUT LEVEL \u003cbr\u003eThe 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 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.\u003cbr\u003e \u003cbr\u003eAVALON VT-737SP FEATURES\u003cbr\u003e\u003cbr\u003eVacuum  tube triode signal path, transformer balanced microphone input,  high-voltage circuits for maximum headroom to +30dB, low noise -92dB,  internal discrete power supply with toroidal transformer, soft-start  tube life extender, stereo link for compressors, all discrete Class A  equalizer with musical passive filter design, sealed silver relays for  signal routing, large control knobs with professional conductive plastic  potentiometers, VU meter for output level monitoring and compressor  gain reduction.\u003c\/p\u003e","brand":"Avalon Design","offers":[{"title":"Default Title","offer_id":44449472184423,"sku":"27450","price":1595.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_27450_1_5905ccfb-5125-4fed-884f-d24e32b8183f.jpg?v=1787089084","url":"https:\/\/vintageking.mom\/products\/avalon-vt-737-sp-mercenary-edition-used","provider":"Vintage King","version":"1.0","type":"link"}
