Contacta con nosotrosManley Voxbox is a 3U all-valve channel strip combining a microphone preamplifier, an ELOP optical compressor, a passive Pultec style equaliser, a de-esser and a limiter. The whole path is valve based, with no op-amps in the signal chain.
A vocal that is finished on the way in
Tracking a vocal through an ordinary preamp leaves you with a take that has to be rescued later with plugins: sibilance, level jumps, no bottom end. The Voxbox does all of that on the way to the converter, while the signal still has full headroom. The de-esser and compressor sit ahead of the equaliser, so lifting the top does not sharpen the sibilance you have just tamed. Compression runs at 3:1 with up to 16 dB of reduction, and switching to limiting turns that into 10:1 and 32 dB when a level jump has to be caught without riding a fader.
Passive equalisation with valve make-up gain
The equaliser section uses genuine inductors and the passive Pultec topology, with gain recovered by a Class-A valve stage. The trick that defines this circuit, boosting and cutting the same low band at once, produces a curve you cannot build on a parametric equaliser. The inputs handle microphone, line and instrument at 2000, 4000 and 100,000 Ohms respectively, so an electric guitar or a synth enters the same path as the microphone.
