The Hear Technologies Hear Back PRO 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 PRO Hub, four Hear Back PRO Mixers, four 50’ Cat6 cables, and two DB25 to 1/4" TRS analog breakout cables. 24-bit A/D and D/A converters deliver detailed audio with extended dynamic range and resolution up to 192 kHz. The low system latency of less than 0.25 milliseconds ensures there will be no monitoring delay.

Artists can make their own headphone mixes from up to 16 analog inputs and a mono mic or stereo aux input, blending levels and pans as they please. Each mixer offers a 3.5mm and 1/4" TRS headphone output to accommodate different headphones. Per-channel input metering on the Hear Back PRO Hub provides clear indication of signal presence and peaking status. Each channel offers a -10 dB pad to minimize distortion for hot signals. If mixing stations are needed for more than four artists, the system is easily expandable via additional Hear Back PRO Mixers (available separately) and other interface cards.
