The Manley VOXBOX Preamp and Voice Processor Offers a Wide Array of Audio Processing with Amazing Audio Quality It looks awesome, but what is it? Primarily, the Manley VOXBOX® is a voice processor- which in itself is not a novel idea, but the time had come to pull out all the stops and introduce a truly professional high-end statement. One that covered the needs of the project songwriters and big-time major studios alike. One whose all-tube signal path could bring every instrument and overdub to life. One that, plain and simple, sounded unquestionably better than the rest, provided flexibility, simplicity, and well thought-out ergonomics. The VOXBOX® is full of features, timeless style, robust build quality, and that world-famous "Manley Sound". That's nice. What's it good for? While still in the designing stages, Manley couldn't help but notice how well it works 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. Stereo using two VOXBOXes? Manley planned for that as well. There are Stereo Links for both 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 The preamplifier is a clone of a highly regarded and popular mic pre: the Manley Mono Microphone Preamplifier! The mic input transformer is Manley's own design wound in-house at the Manley Labs factory. High current 48V Phantom power is switchable from the front panel. 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. These inputs are selected in the middle position of the dual-function phase invert switch. The VOXBOX provides both a transformer balanced XLR output as well as a transformerless "audiophile" 1/4" phone jack output. The Gain switch is actually a clever variable feedback control that changes not only the gain but the slew rate and flavor of the circuit. With it you can choose how laid back and mellow or how up-front and aggressive you want it to get. See "Notes on Variable Feedback" for more info. Headroom is a strong point in this circuit, +31 dBu capable. This is 5 to 10 dB better than almost all other pro gear. The music passes through only the super-clean pure Class A vacuum tube circuitry. There are obvious advantages to this purist approach and foremost is the un-electronic final sound that carries emotion into the digital realm. Compressor This cool compressor design takes our opto-isolator approach of the Manley ELOP® Limiter to the max. Manley adjusted the Ratio down to 3:1 to turn their ELOP into a compressor and added ATTACK and RELEASE controls for more versatility. What is clever 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! Manley also pioneered new thinking in the sidechain by using up to four different time constants simultaneously and controlling them with familiar simple attack, release and threshold controls. They call the approach "Parametric Compression". The optimum settings or presets are developed based on Manley's preferred Vactrols that are used in their own fast ELOP® Limiter, the quick LA-2A's T-4 module, the slower LA-3A and then created more complex special settings. This extended range and method of timing delivers fresh sounds from powerhouse punching drums to super-solid bass yet can also emulate the way good engineers delicately ride a fader while recording. It is transparent and liquid-smooth on vocals, easy to use and accurate. Also rare for an opto-based dynamic processor, this compressor works great on mixes. Of course, you'll be needing two VOXBOXes linked in stereo. EQ The Pultec Mid Frequency Equalizer is included in the VOXBOX®, by popular demand, and it has been extended to span 33 frequencies in 3 bands with 6 new frequencies from 20 Hz to 150 Hz, and 6 more in the highs from 6.4 KHz to 20 KHz. Ever notice that only EQs with real inductors have the bottom end magic or that only Class A circuitry can keep the top end sweet? This is for you. 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 and Limiter Designed by folks with admittedly large gaps between their two front teeth, the VOXBOX® combo also includes a de-esser and peak limiter based on our original ELOP® Limiter design but with an added passive LC network to handle the de-essing four carefully chosen notch frequencies from 3KHz to 12KHz. (That 3 kHz setting really tames those annoying frequencies!) 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 The METER is 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. The sum-total is more than the separate parts: consider the reduced patching, the short path to tape and you having this much immediate control. Manley engineers choose what they use not based entirely on features and functions - but rather they strive for a sound, a certain texture - and the VOXBOX® combo puts the 'Manley Sound' together with 'Your Sound'. Manley Power The MANLEY POWER® power supply is an innovative design developed specifically for Manley Labs, specifically for High Voltage vacuum tubes, and specifically for audio by the world expert team in this technology led by Bruno Putzeys. Proven reliable and sonically superior in the Manley CORE, this power supply provides 300 Volt DC rails to run the vacuum tubes, beefy 6 Volt lines to power them up, along with several other voltage rails for the phantom power and various solid-state control voltages. High Voltage = High Headroom, folks. You will not get near this sonic performance with in any 500-series design. This is Massive audio excellence which starts with this superior power supply. All lines are importantly regulated, low impedance, efficient, and super-quiet in this low radiating high frequency design. The universal mains input accepts any voltage or frequency from anywhere in the world making travel with the VOXBOX a breeze.
