An often overlooked but rewarding source of readily available program material is radio. Cyrus, being based in a country where radio broadcast quality is of the highest order, designed a tuner to enhance the pleasure attainable from live concerts, plays and other programmes available over the airwaves. The Cyrus tuner is a microprocessor-controlled, digitally-synthesised design employing a high quality phase-locked-loop circuit which ensured tuning precision and low distortion.
Engineered to the same high standards as its stablemates, the Cyrus One and Two the Cyrus tuner featured separate regulated power supplies for the digital, RF and audio sections and a powerful toroidal transformer to enhance the sonic performance of the audio output section. The Cyrus tuner had a unique automatic setup facility that, when accessed, scans the entire waveband, entering into its memory all stations with adequate signal strength. Other details incorporated to make the Cyrus tuner a truly functional design included full-function remote control, a 10-digit keypad for instant access to frequency and preset selection, facilities to store 59 FM and 59 AM stations, display on/off for interference-free reception, remote power on/off, remote volume operation and a host of other convenience features.
