Description

AEQ TH-03

The AEQ TH-03 is an advanced digital hybrid that comes in the version of 1 or 2 telephone lines, and either analogue 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 are 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 receiver line. This additional 2 ½ octave 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 is capable of operating with single or dual lines. Independent outputs line level, or multiplexed output provided by its unique multiplexing capabilities. Working with dual lines permits telephone multi-conference, allowing the On-Air personality and two callers to talk and listen to each other simultaneously.

Feedback is eliminated by the digital hybrid. No adjustments are required to operate.
