The sky is full of radio signals which carry an enormous variety of sounds. A high-quality tuner will allow you to make the most of these signals, whether they be music, news, discussions, plays, or live broadcasts which may never be repeated.
The TAG McLaren Audio tuner T20 will bring into your home all of these programmes with minimal distortion or coloration, and complements the most sophisticated audio systems.
Tuner T20
The tuner T20 receives stations broadcasting in FM in hi-fi quality. It also features dedicated AM circuitry for optimum reception of MW and LW broadcasts, without compromising the excellence of TAG McLaren Audio's proprietary FM input circuitry.
Although limited in sound quality compared to FM, AM broadcasts (often from abroad) offer their own unique blend of programmes.
Digitally-synthesized tuning, automatic and manual station selection, 39 user-programmable pre-set stations (including all settings), calibrated signal strenght meter, mono, stereo and high-blend modes, and weak signal enhancement are just a few of the many features built in to this precision instrument.
Without a TAG McLaren Audio tuner T20, any high-specification audio system is simply incomplete.
