The two audio adaptors have 3.5mm stereo inputs and are designed to connect MP3 players, laptops, etc., to house sound systems - model 318 provides mic level output via an XLR connector, and model 319 provides line level output via a 3-way terminal block. Both products feature level controls and ground lift switches, and transformer isolation provides immunity from hum and buzz caused by ground loops and RF interference.
The impedance matching transformers have XLR to BNC connections and adapt 110 ohm to 75 ohm for AES/EBU, etc.
The range can be used as stand-alone adaptors, rear mounted into modular rack panels or permanently installed into any number of custom racks and wall plates.
