The RC-11 deck was a professional studio recorder available in rack, console or portable version. It had three heads, three motors and a 10½ inch reel capacity. A dual-speed capstan motor provided playing speeds of 15 and 7½ ips.
Features included push-button solenoid operation allowing remote control, dynamic braking, rheostat-adjustable fast forward and rewind and a simplified threading path with easy editing access.
The RC-11 was of unitised construction. The capstan drive unit was self-contained with motor, flywheel capstan shaft, pressure pulley and solenoid all pre-mounted on a cast aluminium assembly which was quickly removable for service or replacement. The remainder of the components were mounted on a heavy, ribbed, cast aluminium panel which could be rack, case or console mounted.
