Mitsubishi M-T01 cassette deck

In designing the cassette tape deck for our microcomponent series we have not been too concerned with reducing the size; instead, while maintaining the same attractive, warm champagne gold hairline finish we have designed it to the same dimensions as the M-A01 power amplifier

Front Loading Format

Rather than adopt the horizontal insert type of cassette loading often used on compact cassette formats ,  inconvenient for tape head cleaning and subject to tape snarl-ups, the M-T01 features frontal loading, with full tape visibility and a hinged tape head cover that protects the head assembly from dust and higes down for easy access.

Feather-Touch Microswitch Controls

For smooth and rapid switching between different operatingirectly. To go from fast rewind into the play mode  just press the appropriate feather touch microswitches; the changeover is almost instantaneous, with no tape spillage. All operations are just as simple and foolproof.

ASPS

Mitsubishi's automatic spacing pause system ASPS puts a few seconds of silent spacing between different music selections without having to alter recording levels or go out of the recording mode.

Closed-Loop Dual-capstan Drive

For the last word in stable tape drive, greatly reducing drop-outs and changes in level due to variations in tape tension over the heads the tape is held between two capstans and their corresponding pinch rollers on the take-up and supply sides, unlike the normal single-capstan plus pinch roller combination. The mechanism itself is mounted on a high precision die-cast metal base, and is highly resistant to vibration and other harmful influences. This, and a phase locked loop (PLL) with a quartz-crystal oscillator as the standard for controlling the speed of the DC servomotor, bring wow and flutter down to a completely negligible 0,05% WRMS. The recording/playback head is of sendust, with excellent magnetic and wear-resistant properties, and is largely responsible for the good frequency response.

Peak level Meters

The fast-response peak reading meters on the M-T01 make it easy to achieve recordings with the maximum of Signal-to-Noise ratio and the minimum of distortion by giving accurate indication of critical peak signal levels.
