The TRX-20 is a compact lightweight adapter that interfaces with any single or multi line analog telephone with a wired handset and either a digital recorder, tape recorder or transcribing machine. It's the perfect tool for recording both sides of a telephone conversation.
Small enough to fit in the palm of your hand, the TRX-20 features a modular receiver plug at one end and a coiled connector cord at the other end. The unit easily connects between your phone base and the handset. And there's no need for hardwiring a telephone adapter. Simply disconnect your hand set and plug in the TRX-20 coiled connector cord. Then take the handset cord that is connected to your phone base and plug it into your TRX-20 modular receiver plug. It's that easy! A separate audio cord from your TRX-20 plugs into the microphone jack of your digital recorder, tape recorder of transcriber with a 3.5mm plug.
