Akai GX-747

1 9 8 2 january 1982
1 9 8 5 1985

One of the most remembered and sought-after reel-to-reel recorder although, arguably, not the "best" - we could name the Technics RS-1500U series or the Sony TC-880-2 to name but two masterpieces.

But what lavish looks the 747 was graced with ! And it sold extremely well, too ! But it couldn't spin at 38cm/s.

The GX-747 wasn't an all-new design : it was much too late in 1981 to develop for an already weakening market.
The 747 is thus mainly an updated GX-646 which itself was an updated GX-635...

An anything dbx-equipped, the sonic results are amazing (a m a z i n g) but whether to give credit to the recorder or the dbx system is an open debate.
Oh, well - it mainly is the dbx.

There were six versions in total :
GX-747 with LED meters (silver or black)
GX-747 with VU meters (silver or black)
GX-747dbx (silver or black)
The dbx version was only available with VU meters...

Until the japanese catalog I have is translated from japanese to english, you can read more about the GX-646 at Frank Oomen's website.
