Additional Details


A four-track stereo, four speed semi-professional recorder with the world’s
first cross-field bias system and a single, hysteresis-synchronous two-speed
motor.   A removable capstan sleeve plus the two motor speeds gave playing speeds of 1, 3¾ , 7½ &
15 ips and even at the slowest speed the wow and flutter were negligible.
Quite similar to it’s predecessor, the M6.
From a 1964 equipment review… Appearance and styling are severely functional but all the controls are well placed and does its job efficiently.  The recorder can be played in any position, on it’s back, upright or at an angle and is transportable, rather than portable.
Standard ¼” jack-plugs are used for all input and output connections which include head output, and pre-amplifier output as well as microphone and speaker connections….A recorder for the real enthusiast or semi-professional rather than the domestic user…”
