Nakamichi RX-303 cassette deck

 

Unidirectional Auto Reverse Cassette Deck

A 2-head , Closed-Loop Dual-Capstan record/playback auto reverse deck rivalling the RX-505 in top performance quality.


 

The RX-303 is designed with the same Unidirectional Auto reverse mechanism and high-precision transport employed in the RX-505, for exceptionally high reproduction quality. The RX-303 incorporates a triple laminated core Sendust record/playback head instead, yet provides wide, flat frequency response and extremely low distortion rivalling that of the Discrete Three-Head System. Low-noise, low-distortion amplifiers, the same as those used in the RX-505, ensure the finest possible reproduction performance, and the same Closed-Loop Dual-Capstan Transport silent mechanism guarantees incredibly accurate, stable tape travel characteristics. Extra operating control and convenience is provided with automatic fade-out and fade-in prior to and after the reverse operation, for smooth musical transistors between sides of a tape. A host of other features, combined with the outstanding reproduction quality of the Rx-303, make this deck a strong rival to the RX-505 in all-around performance.
