Additional Details


The GX-400D- SS utilized the GX 400D PRO tape deck, featuring a dual capstan drive system with a self-lubricating AC servo motor and eddy current reel motors. It had three tape-speeds: 3¾ , 7½ and 15 ips, auto shut off capability and a tape cueing function.

A four channel / two channel mode selector switch converted the recorder from 4-channel surround sound to two channel stereo and in addition, ‘Quadra-Sync’ allowed instant monitoring of any existing track whilst recording on any other track (similar to the TEAC simulsync system).
Auto-reverse was selectable in two channel stereo mode with an auto-repeat function being available when the recorder was operating in four-channel mode. Normal and low noise tapes could be selected via a switch. The unit came in a silver or black finish (the latter having blue VU meters similar to the GX 260D).
