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. | Input: | Unbalanced via standard phono jack | | Input Level: | -10 dBV nominal | | Gain: | -10 dB to +25 dB (adjustable) | | Frequency Response: | Tailored to phone systems within 20 Hz to 20 kHz spectrum | | THD+N: | < 0.5% (1 kHz @ Maximum Output 1 W)
