Accuphase T-1200 DDS FM Stereo Tuner

The Accuphase T-1200 is a successor model to the highly praised T-1100 and T-1000. Thanks to a blend of the latest RF circuit design, with sophisticated digital signal processing implemented by a high speed, high precision DSP chip. It has become possible to move most major functions of the tuner into the digital domain without sacrificing performance or sound quality. Audiophiles and music lovers can now enjoy FM stereo at its best.

The newly developed front end features a double tuned circuit that optimizes sensitivity and selectivity, as well as the revolutionary DDS (Direct Digital Synthesis) principle for the local oscillator. All functions after the intermediate frequency (IF) stage are implemented using digital signal processing in completely new and innovative ways. This comprises the variable bandwidth IF filter, multipath reduction function, digital FM detector and DS-DC stereo demodulator. The result is an FM tuner unlike any other, offering further enhanced performance and sound quality.

Other attractive features include a 20 station memory, a coaxial output for digital signal connection, two sets of line and balanced analog outputs, and a supplied Remote Commander for operation convenience. In summary, this is a lavishly designed FM tuner that will meet and surpass even the highest expectation
