Description
The Jabra AT3M Plug-Prong Amplifier with Mute (01-0437) is an in-line telephone amplifier that inserts between the telephone handset and the headset cord to boost audio volume and add a hardware mute control. It is designed for corded headset setups where the phone's native output level is insufficient or where a dedicated mute button is needed.
The Telecom Spot Take
Some older analog business phones and certain PBX configurations don't provide enough headset output volume for comfortable listening, especially in noisy environments. The AT3M amplifies the signal inline without requiring any rewiring or phone modification — it simply plugs into the phone handset port and accepts the headset cord on the output side. The built-in mute button is a practical addition for users whose phone doesn't have a reachable mute control on the desk surface.
Key Features
- Inline audio amplification — Boosts phone audio output for clear hearing in high-volume environments.
- Hardware mute button — Adds convenient mute control where the phone doesn't provide one within reach.
- No phone modification needed — Plug-prong installation — inserts into standard handset port.
- Corded headset compatible — Works with any headset connecting through the standard handset port path.
