Hear Technologies Hear Back PRO Mixer (Single)

This is the Hear Back PRO Mixer sold on its own, for a shop that needs to add a position to an existing Hub or replace a single unit rather than buy a full four-pack. On firmware V6 and later it 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. Power and audio arrive together over a single Cat6 cable from the Hub's Network Card.

The PRO Digital Overlay variant ships with the ultra-thin OLED faceplate already installed. It replaces the standard scribble strip with high-contrast graphical channel and mixer-function labeling, updated remotely from a computer, and adds less than 3mm to the Mixer's thickness. Either version has a side-mounted expansion slot for future accessories.
