Its tailored response keeps on-hold audio clear for callers across a wide range of handsets and phone lines.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/tx-1w.jpg\" alt=\"RDL TX-1W - 1 W Music-on-Hold Amplifier for Phone Systems\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eConventional amplifiers often produce annoying artifacts at the caller's earpiece, and simple high-frequency rolloff tends to sound muffled. The TX-1W uses a spectral response characterized for telephone audio distribution, producing a lively, crisp sound without the resonances and distortion that cause listener fatigue. It accepts a -10 dBV source on a phono jack, offers -10 dB to +25 dB of adjustable gain, and provides a balanced 600 Ω transformer-driver output plus an unbalanced output up to 1 W.
