It looks awesome, but what is it?
The Manley VOXBOX features an all-tube signal path that brings every instrument and overdub to life. Primarily, it is a voice processor which in itself is not a novel idea, but the time had come to pull out all the stops and make a truly professional high-end statement. One that covered the needs of the project songwriters and big-time major studios alike.
One that, plain and simple, sounded unquestionably better than the rest, provided flexibility, simplicity, and well thought-out ergonomics. Full of features, timeless style, robust build quality, and that world-famous "Manley Sound", we present to you the MANLEY VOXBOX®
That's Nice. What's It Good For?
While we were designing the VOXBOX we 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? You know we couldn't resist planning 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 Section:
The preamplifier is a clone of a highly regarded and popular mic pre: the Manley Mono Microphone Preamplifier! The mic input transformer is our 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. We provide both 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, +31dBu capable. This is 5 to 10 dB better than almost all other pro gear. The music passes through only our super-clean pure Class A vacuum tube circuitry. There are obvious advantages to our purist approach and foremost is the un-electronic final sound that carries emotion into the digital realm.
This cool compressor design takes our opto-isolator approach of the Manley ELOP Limiter to the max. We adjusted the Ratio down to 3:1 to turn our 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! We 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. We call the approach "Parametric Compression". We developed optimum settings or presets based our favorite Vactrols that we use in our 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 dynam
