Hear Technologies Hear Back PRO Personal Monitor System, Four Pack
Hear Back PRO is a modular personal monitoring platform built around a rack Hub and a set of desktop Mixers linked over Gigabit Ethernet on standard Cat6, with power and audio on the same cable and runs up to 500 feet. Each four pack contains four Mixers, one Hub frame, a Network card, four 50 foot Cat6 cables, an input card, and a tote bag; analog packs add two DA-88 style cables.
The Hub frame takes four cards, so the input format is a choice rather than a fixed design: analog, Dante, ADAT, AES/EBU, Waves SoundGrid, or MADI on the input side, plus word clock, virtual mixer, network, or analog output cards. One Hub carries up to 32 input channels and hubs daisy chain from there. On firmware V6 and later a Mixer gives the player local control of up to 138 channels, that is 128 channels plus a stereo AUX input and up to four stereo intercom inputs, driven by a headphone amp rated 2.2 watts into 25 ohms. Each part number above is the same four pack supplied with a different input card.
