Additional Details

Description

Selling right up until 1984 and still one of the most popular Akai recorders today on the 2nd hand
market, the GX-4000D was an improved version of the 4000DS MKII, using Akai’s GX heads (with a guaranteed 150,000 hours use and a higher frequency response).
Improvements/modification included: re-location of the track selector switch (now next to the head cover instead of on top of it). an extra output level control on the front panel. the capstan speed change sleeve
was hidden under the head cover when not in use. and 50% LESS wow and flutter than the earlier 4000DS mk II.
The DB version was equipped with Dolby Noise reduction, the Dolby switch replacing the Sound On Sound switch on the GX-4000D. The GX-4000DB, however, still retained the SOS function via a pull-switch on the left line-in knob.
This unit was also available with a matt-black panel.
