Information

FM Front End with a Cascade-connected Junction-type Field Effect Transistor (FET) The TX-6700 adopts a high-frequency amplification one-stage front end which employs a 3-gang variable capacitor and a cascade-connected junction-type FET featuring high gain and low noise. These parts enhance the ability of the Tuner to eliminate image interference ratio, spurious radiation and other interference, and they provide a sufficiently high practical sensitivity of (mono). Furthermore, they ensure stable FM reception even in fringe areas and locations close to the transmitter. Low-distortion, High-S/N FM IF Section The FM IF section incorporates two sets of dual-element ceramic filters with superb phase characteristics. Between the filters there is a buffer Amplifier for ample selectivity and high sensitivity. Furthermore, the combination of these features guarantees stable reception even in locations affected by strong input interference signals adjacent to the station which has been tuned in. Distortion and the signal-to-noise ratio are improved by the 3-stage differential Amplifier, 5-stage limiter and newly developed ICs which integrate a discriminator offering top detection efficiency. MPX Section which uses a new PLL IC with a Built-in Pilot Signal Auto-canceller and Low-distortion Design The newly developed PLL 1C contains a canceller circuit which automatically cancels out the pilot signal. Without affecting the frequency response at the high-end, this feature suppresses the leak carrier and permits a broad range. In addition, the demodulator has a built-in NFB circuit which enhances the signal-to-noise ratio and helps to realize a low distortion rate. IC-based AM Tuner The AM Tuner section integrates the high-frequency and intermediate frequency amplification circuits as well as the discriminator onto newly developed IC’s, and this configuration improves both the frequency response and the elimination of interference. Another attraction is the fully-fledged AGC circuit which enables AM broadcasts to be received stably and with extremely low levels of distortion even when the Tuner is located in the vicinity of the transmitter. Easy-to-tune Front Panel Design The panel is designed for easy operation: the tuning scale is a long 250 mm to facilitate tuning, the tuning meter and signal meter are large for easy read out and they are located in the center. The overall design harmonizes with that of other Pioneer hi-fi Components for increased visual appeal.
