Manley VOXBOX
Compressor & Limiter
The Manley VOXBOX is primarily a voice processor, carrying the world famous "Manley Sound" heritage, which also works well on other instruments besides voice. There are some great settings for drums, bass, guitar, and keys and the two separate sections can be used together or independently. There are Stereo Links for the compressor and the De-Ess/Limiter sections, special compression settings and super-sweet EQ frequencies for your mix or pre-mastering. So don't just use it for voice. The name VOXBOX represents only the beginning.
MICROPHONE PREAMPLIFIER SECTION:
The mic input transformer is a hand-made design at the Manley Labs factory. A simple and effective passive BASS CUT switch kills rumble and reduces popping. The INPUT ATTENUATOR is a variable pad control situated before the first tube stage allowing the preamplifier to accommodate +4 line level signals via the balanced LINE INPUT and instruments via the front panel 1/4" DIRECT INPUT. Headroom is a strong point in this circuit, +31dBu capable. This is 5 to 10dB better than almost all other pro gear!
COMPRESSOR SECTION
The importance here is how the signal is compressed before it hits the tubes with no detrimental effect on distortion or frequency response. This way, it can prevent mic-pre clipping and eliminate whole stages of electronics. This cuts the typical path of mic to tape in half!
EQ SECTION
The equalizer has been extended to 33 frequencies in 3 bands with 6 new frequencies from 20Hz to 150Hz and 6 more in the highs from 6.4kHz to 20kHz. The EQ INPUT switch patches in the Line Input, Preamp Output, or the INSERT return. This switch serves double-duty acting as a bypass switch for the preamp and/or external processors or for processing two different tracks
DE-ESSER & LIMITER SECTION
It has an added passive LC network to handle the de-essing four carefully chosen notch frequencies from 3kHz to 12kHz. The fifth position gives you a limiter which totally mimics the famous LA-2A. This means you can both compress pre-EQ then limit here post-EQ. Another cool feature is the ability to insert this de-esser silently and smoothly as the music plays, using it as needed.
THE METER
It's a full size illuminated Sifam VU meter. A five-position switch shows three audio levels: the line input, the preamp output and the final output. It also shows compressor gain reduction and the de-esser/limiter action. Other clever innovations incorporated into the VOXBOX combo include warm-up muting circuitry, extensive magnetic field containment, "smart - grounding", and silent switching.
