The TBP-I/O module is an optional 1ch-wide module which can be placed anywhere on the surface, to add a convenient Talkback Input and an Headphone Output to your Quasar.

It comes with its own headphone amp board that must be plugged into the Quasar Rear I/O module, to let the console receive any line signal and turn it into a high-quality, hi-power headphone output.

The HP Amp board is powered by the console and offers direct analog connections to/from Axia xNodes via RJ-45 connectors. TB in: XLR-F, HP out: 1/4"(6.3mm) TRS jack.
