The Hear Technologies Hear Back 4-Pack is a personal mixing system offering independent multi-channel mixing for up to four performers in the studio or on stage. It includes one Hear Back Hub, four Hear Back Mixers, four 50’ Cat5e cables, and a DB25 analog cable. 24-bit A/D and D/A converters deliver detailed audio with extended dynamic range. After choosing a digital or analog input source on the Hear Back Hub, artists can make their own headphone mixes, blending levels as they please. Built-in DSP limiters prevent clipping and keep the analog outputs free of distortion. Per-channel input metering on the Hear Back Hub and multiple status LEDs on the Hear Back Mixers provide clear indication of vital information. If mixing stations are needed for more than four artists, the system is easily expandable via additional Hear Back Mixers (available separately).

  • Hear Back Hub 1 RU Signal Distribution System for Hear Back Mixers

    The Hear Technologies Hear Back Hub is a 1 RU signal distribution system designed to provide low-latency, long-distance audio transmission for musicians, vocalists, and various performers using Hear Back Mixers in recording studios, rehearsal spaces, and live stage applications. Select between three different 8-channel sources—ADAT optical, DB25 balanced analog, or RJ45 HearBus. Per-channel input metering indicates signal levels at -32/-10/+4/+16 dBu.

    Eight RJ45 mixer outputs send power and eight channels of audio via Cat5e connections to Hear Back Mixers (available separately). An additional RJ45 output jack allows daisy-chaining to another Hear Back Hub. 24-bit A/D converters ensure proper conversion of the analog input signal. An internal temperature-controlled fan keeps the unit cool and operationally stable.
