The TH-03 is an advanced digital hybrid that comes with 2 telephone lines, and either analog or AES/EBU digital inputs and outputs. The TH-03 has built-in signal level metering for each hybrid line. Feedback is automatically mitigated by the digital hybrid, and no adjustments or calibration required.
It includes a mix-minus bus for multiplex communication while on-air or on-hold in the studio: Pressing the MPX button automatically establishes a conference between the two telephone lines, so only a single audio feed to and from the hybrid to the mixing console is needed.
