One Heavenly Tube Preamp!

Ever since this "Class A Mic Processor" was introduced in the late 1990s, studios large and small have relied on its platinum-sounding tube preamplification, world-class optical compressor, and musical four-band equalization controls. A gleaming, glowing VT-737SP in your rack tells clients you've been in this game for more than little while, and that you're ready for anything they've got. Let's take a closer look at this modern classic:

One Classy Front End

Technically speaking, the VT-737SP's Class A preamplification section is arranged as two cascaded, dual vacuum tube triodes, configured with minimum negative feedback as single-ended, anode-coupled followers. What matters, however, is the sound that this circuit produces. The Avalon sound is one that's beautifully transparent and smooth. It takes whatever instrument, electronic audio, or human voice you feed into it, and gets it ready for international stardom, all without changing the central character of the signal. And the VT-737SP is ready for any input: it supplies 48 volts of phantom power for use with highly detailed vocal microphones, sports a high-gain switch for extended headroom (great for loud sources like amplified guitar), and a direct hi-z input for tracking warm, shimmering electric bass.

A Tube Compressor That's Opto-Smooth

From the preamp stage, your signal then travels to Avalon's opto-compressor. While it can be used on any signal, the VT-737SP's compression profile works best on instruments with a long decay. Optical compressors respond to changes in dynamics by presenting a photo-resistor with a light source that dims as the volume gets lower--this non-linear decay can't be matched by solid-state compression circuits, and makes sources like voice, guitar, bass, string ensembles, and piano really sing and breathe. Also handy: if you're tracking a stereo source like drum overheads or a choir and you've got two VT-737SPs, you can link their compression circuits together for perfectly synchronized dynamics processing.
