AEQ TH-03 – Compact Digital Telephone Hybrid

Product Overview

AEQ TH-03 telephone hybrid is a compact digital unit designed to bring clean, reliable phone calls into professional broadcast studios. The AEQ TH-03 telephone hybrid is available in single or dual-line versions and offers both analog and AES/EBU digital audio I/O, so it integrates easily with modern consoles and routers. Automatic digital hybrid processing delivers high return loss and stable line matching, reducing feedback and echo without constant manual tweaking.

Main Features

• Compact 19″ 1U AEQ TH-03 telephone hybrid with versions for one or two PSTN telephone lines.
• Balanced analog and optional AES/EBU digital inputs and outputs for flexible console integration.
• Automatic echo cancellation and hybrid nulling in the digital domain for clearer, more intelligible caller audio.
• Simple front-panel controls for Off-Hook, On-Air, level trim and frequency extender, plus status LEDs for line and audio activity.
• Integrated mix-minus function on dual-line models, allowing easy conferencing of two callers with the presenter on a single bus.
• Remote GPIO for call control and tally, making it easy to interface the AEQ TH-03 telephone hybrid with consoles, cough buttons and studio signalling systems.

Frequency Extender and Applications

The built-in frequency extender shifts the audio spectrum to partially overcome the limited bandwidth of standard telephone lines, adding warmth and presence to callers’ voices. AEQ TH-03 telephone hybrid is ideal for live phone-ins, talk shows, news contributions and any production where dependable, good-sounding phone calls are required. Its small footprint and straightforward controls suit both main on-air studios and secondary or OB racks.
