MITSUBISHI micro 01 (1979) - High Performance, Small Package

MITSUBISHI micro hifi

Mitsubishi (Diatone in Japan) has put big audio performance into a series of precise little audio components - microcomponents. Stereo components that are compact, but can hardly be called compacts. They have the same high-performance characteristics as full size components. The Micro FM tuner is using a quartz-PLL synthesizer tuning system that has absolutely no drift. The Micro Cassette Deck has a Dual Capstan Drive mechanism mounted in a precise die-cast chassis, 2 head configuration, separate Bias and EQ settings, Feather Touch Logic Control and Dolby noise reduction system. For power, the Micro power-amplifier was unbeatable at this size. The little "direct coupled" powerhouse puts out 70 watts per channel. Total harmonic distortion is only 0.01% for 30 watts per channel. The Micro Preamp is made to complement the power amplifier and faithfully conduct any signal source that goes through it. It has a built-in moving-coil head amplifier and a signal-to-noise ratio of 77dB and 0.005% THD. The final touch was to finish them with Champagne Gold faceplates. The MITSUBISHI micro 01 (DIATONE µ in Japan) cosnsists of  M-F01 tuner, M-P01 pre-amp, M-A01 power-amp and M-T01 cassette deck.

PCM Adapter - Old Digital Audio Format

Before the introduction of a standardized format to record digital audio to a tape (the DAT recorder) the practice was  to use a PCM adapter (pulse code modulation) connected to a video recorder to record the digital audio signal to tape. The PCM adapter was connected to a video recorder using the video in/out of the unit in order to record the PCM coded audio digital signal where normally the video signal is recorded. The reason to do this was that a linear tape recorder did not have sufficient bandwidth to record large volumes of PCM data while video recorders were available both for studio and home use and the rotary video heads used in a video recorder had sufficient bandwidth to do this. Most video-based PCM adaptors record audio at 14 bits quantization, and a sampling frequency of 44.056 kHz.
