    The SixMix is designed for live broadcasting as well as recording, editing, and other production tasks. There is a stereo programme mixing bus, a mix-minus output, a cue bus with internal cue speaker, and comprehensive headphones and monitor systems. Other features include a talkback system, guest headphone facilities, and accurate audio level metering. SixMix is ideally suited for use in a broadcast studio, news room, radio automation system, remote broadcast facility, emergency studio, internet broadcast station, or editing suite. With a footprint about the size of a laptop computer, it is a compact yet versatile and powerful audio production tool that is intuitive and easy to use.
  • SixMix accommodates 10 inputs with 6 mixing channels. Channels 1 & 2 are for dynamic microphones. Each Mic channel includes an on/off switch and a cough button. 

    Channels 3 through 6 are for line-level sources like CD players. Each line channel accepts two stereo line sources: the ‘A’ input is for professional equipment and the ‘B’ input is for consumer units. 
    Input 6A is the built-in digital audio codec for recording and playback using a computer. Any O/S and software that supports USB 1.1 (or higher) can be used - no special software or drivers are needed.  The PC-Direct SPDIF digital output permits feeding digital PC-playback audio (only) to a transmitter or web-streaming interface.
    SixMix also includes a mix-minus output for use with a telephone hybrid. And a cue system with a built-in cue speaker.  Two headphone facilities are provided, the second using a Henry Engineering MultiPhones Guest Pod.
    Mic logic tally outputs are provided to interface with a Henry Engineering Superelay for control of on the air tally lights. Other features include accurate LED VU meters that conform to ANSI standards for VU meter ballistic response, and a front panel 3.5mm stereo input jack for quick connections.
    SixMix offers the best of both worlds: the reliability of an analogue console with the efficiency of digital audio.
