NEW : "VARISTAGE" (tm) STEREO boom remote control
  • Allow to control two separate ouput channels separately or with one knob only (LINK)
  • ideal for stereo MS booming with only one knob on the boom !
  • Also, allow to control two groups of microphones : 2x 2 mics, or 1x 1 mic + 1x 3 mics, or 1x 1 mic + 1x 2 mics, or 1x 4 mics in two independants groups.
  • Internal limiters of the 4Mix can still operate to provide a total modulation security
  • provision for remote visual control of the remote volume action (Led or meter in the field of view of the boom operator)
  • outstanding 38dB volume control range

NEW 4Mix V2 FEATURES available DECEMBER 2005
  • VARISTAGE remote control
  • MS matrix decoding on phone monitor selector
  • TAPE / MUTE / DIRECT selector in front
  • PHASE revert switch on input 2 (in place of Mic / line Pad)
  • LINK switch to control a stereo pair on input 2 knob
  • LIMITER LED in front to control the limiter action
  • NEW PAN control knobs for better operation

KEY FEATURES
  • ultra high-efficiency circuitry allows the mixer to run for at least 22 hours with 48V powered microphones and up to 32 hours with dynamic or 12V powered microphone with a single set of alkaline batteries. This means nearly a week of work where the other well known mixers start hissing after a few hours with new batteries.
  • battery cost per hour 2 to 5 times lower than competitors
  • discret transistor ultra low noise input stage (zero horrible SSM2017/2019 !!)
  • all controls accessible on the 3 faces. No hidden controls inside nor on top or on bottom side
  • Easy access to all control even with gloves on. Large rotary faders, well separated from each other made for the adult hand
  • 23 switchs allow more than 550.000 different settings.
  • individual phantom power choice 12/0/48 V per channel
  • individual peak LED per channel
  • big 36mm Vumeters with permanent light control for a perfect visibility in all lighting conditions from bright sunlight to dark
  • optical output limiters studio quality (zero VCA ....)
  • true PANPOT potentiometer per channel
  • sturdy aluminum and steel chassis : passes under car's tires with no problem
  • easy maintenance : ZERO surface mount devices (SMD)


Developed with input from the industry's top audio engineers, the 4MIX Field Mixer encompasses the audio performance, feature set, and mechanical construction demanded by those who rely on audio gear for their livehood.

4MIX is designed to withstand the physical and environmental extremes of field production. Its compact mechanic construction strikes the perfect balance between access to all fonctions (even wearing gloves), uncluttered design, and durability. All controls are located on the front and side panels and are ergonomically laid out for operator convenience.

Far from the mad-science of compurerized today's jewels (and tomorrow from the past), 4MIX mixer has been designed for ease of operation, reliability, and outstanding audio quality.
4MIX is dedicated to:

the ones who are fed up with the clumsy sound of professional mixers (portable or not ...)
the ones who are fed up to replace batteries one or two times a day (...)
the ones who are fed up to program a computer to get some sound (Sound Devices, Sony, ...)
the ones who are fed up with plastic switches (Rolls, Cooper, Sound Devices, Shure, ...)
the ones who are fed up to set up the mixer with a screwdriver (Shure, Rolls, Sound Devices, Cooper, SQN,...)
the ones who are fed up to put the mixer out of its brace to access to some controls (SQN, ...)
the ones who are fed up to adjust bargraph luminosity each minute (Sound Devices, Went, ....)
the ones who prefer serviceable products (!!! ....)
to the ones who prefer to spare and buy better microphones (DPA, Shoeps, AKG, Sennheiser MKH, Neumann ...)
to the ones who have something between the ears (;-)
to all the ones that sound, voices and music can move ....

TECHNOLOGY TO SERVE TRANSPARENCY
  • All internal sound pollution sources have been avoild :
    • zero CMOS logic switches
    • zero switching transistor on the signal path
    • zero poor sounding SSM2017/2019 input stage
    • zero switching power supply ( DC/DC converter)
    • zero computer onboard (CPU)
    • zero screen
    • zero LED bargraph
    • zero voltage controled amplifier (VCA)
    • zero digital converter (AD & DAC)
    • zero internal wiring with their connectors
    • zero surface mount component : poor linearity and hardly serviceable
    • zero multilayer circuit board : non serviceable at all !
    • zero hard to find or dedicated components
    • etc...
  • extensive use of mylar capacitor, much more expensive and reliable and also much better for the sound.
  • All connectors, switches and components are in direct contact : where is no wire nor internal connector on the signal path. This is to preserve the sound purety.
  • ALPS and VISHAY SPECTROL high quality potentiometers
  • NEUTRIK gold plated connectors
  • All professional metal toggle switches (Nagra style)

This makes the 4MIX an absolutely unique product for transparency compared to all its competitors.

DON'T BELIEVE, JUST LISTEN !!
