Description

The GX635 and 636 were very similar, all having a symmetrical 6-head design (Glass Crystal) which permitted both playback and recording in both directions.
The GX-635D was the first unit in the series (1979) and was very likely Akai’s first recorder with IC logic controlled tape function controls. It had a pitch control function, recording mute and a programmable record
timer. Line and mic mixing was also possible with separate microphone and line-in level controls. These controls were fitted with a “memory ring” which rotated when the level was increased but remained in
position when decreased, giving a ‘memory’ of the setting. The direct drive, AC servo capstan motor is frequency-controlled.

Akai also marketed a GX-635DB with Dolby B which did not have the timer switch. Both models were also available with a flat black finish but were sold in smaller quantities as silver was still holding greater popularity for audio equipment of the time.
