Additional Details


One of Brenell’s last semi-professional
recorders before they moved exclusively into the 1″ professional
multi-track market. This was a two-speed, 3-motor machine with a 10½ inch reel capacity.
Capstan drive was provided by a hysteresis synchronous outer rotor motor
with a high starting torque. This and the dynamically balanced flywheel
were mounted in heavy duty bearings.
Adjustable band brakes were fitted and operated by solenoids to ensure
for smooth and efficient braking on the large hubs.
All transport functions were operated by solenoid feather-touch push
buttons. The machine could be biased for specific tapes without internal
adjustment. Individual channel bias pre-sets were mounted above the VU
meters on the front panel
