The TX‑1W is the ideal choice in on‑site installations where the central telephone switching unit needs to be fed with music, voice or combined music/voice signals.
There is a wide variety of telephone instruments in use. When a caller is placed on hold, the audio quality perceived is affected by the caller's own telephone, as well as the telephone lines, central switch and on‑site equipment. Due to these variations, conventional audio amplifiers used as music‑on‑hold drivers frequently produce annoying artifacts at the caller's earpiece. Attempts to reduce listener fatigue through high‑frequency rolloff alone tend to produce a muffled, tired sound. The TX‑1W features a spectral response specifically characterized to match the broadest variations in telephone audio distribution, producing a lively, crisp, interesting sound without the annoying resonances and distortions prone to creating listener fatigue.
