Support Documentation:

The TH-03 is an advanced digital hybrid that comes in versions for 1 or 2 telephone lines, and either analog or AES/EBU digital inputs and outputs.

Each model has built-in signal level metering for each hybrid line. Feedback is automatically mitigated by the digital hybrid, and no adjustments or calibration required. The two line models include 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. The TH-03 takes care of simultaneously getting both in-bound calls to the console, and provides audio from the console back to each individual telephone line, with both console audio and the other callers audio. The TH-03 also has AEQ's exclusive built-in frequency extender. When activated, it moves all frequencies 250 Hz upwards on the send line and 250 Hz downwards on the receive line.

This additional 2 ½ octaves results in enhanced bass frequencies. To use the frequency extender functionality, another AEQ hybrid must be used at the far end. Each telephone line incorporates a SET port which is disabled when the hybrid is on-air. Each of the TH-03's telephone lines Off-Hook, Frequency Extender, and On-Air functions can be controlled locally via the front panel, or remotely using a console or a remote control panel. The TH-03 also has outputs for remote signaling of RING, WAIT, ON-AIR and EXTENDED MODE.
