Reviews[edit]
- A premium stereo tuner from Pioneer with automatic noise reduction.
- The advanced hi-fi technology in this unit of the time, especially with the rec level check, makes it a very valuable tuner for anyone making recordings from the radio. This uses a signal generator to send a 440Hz signal to the output of a highly stable IC every 1.6 seconds - at the level of a 50% FM modulation.
