T-1200 DDS FM Stereo Tuner

Using a blend of latest RF circuit design with sophisticated digital signal processing, most major
functions after the intermediate frequency stage such as the variable bandwidth IF filter, multipath
reduction, digital FM demodulator and DS-DC stereo demodulation have been moved to software on
the DSP chip. Manual tuning using the pulse tuning method, plus 20-station memory tuning. A digital
output provides further flexibility. Realizing impeccable sound quality and outstanding performance in
an easy to use format, this FM tuner has been developed for demanding audio and music connoisseurs.

  • Double-tuned front end easily handles high signal levels
  • Revolutionary DDS principle for local oscillator
  • Variable bandwidth IF filter prevents interference
  • Multipath reduction function
  • Digital FM demodulator keeps distortion and noise to a minimum
  • DS-DC achieves ideal stereo demodulation with DSP technology
  • MDS type D/A converter
  • Memory buttons give quick access to 20 stations

Remarks

  •  An FM antenna is required to use the T-1200. Please consult your dealer regarding antenna installation.
  • In residences with shared antenna systems, confirm that the antenna outlet carries FM signals.
  • Use a 75-ohm coaxial cable with F type plug for the antenna connection.
  • This product is available in versions for 120/220/230V AC. Make sure that the voltage shown on the rear panel matches the AC line voltage in your area.
  • 230V version has an Eco Mode that switches power off after 120 minutes of inactivity.
  • The shape of the AC inlet and plug of the supplied power cord depends on the voltage rating and destination country.
  • The reception frequency range, number of display digits, and tuning frequency steps differ in models for different countries. The antenna connector may also be an IEC type or F type connector. Please verify that you have the correct model for your area
