Additional Details


The PRO-1000 was a semi-professional deck from Akai, seemingly only made for the US, Canadian & Japanese markets between 1977 and 1982. None of Akai’s European catalogues from the late 1970’s make any reference to it and no mention of it in any British or Australian literature.
It had separate transport and electronics units which were joined by three cables, enabling them to be placed side by side or with the transport atop of the electronics unit. It had three speeds, half track recording/quarter track playback  functionality, four-in, two-out mixer with panning and many other features, even a pink noise generator plus connections for optional external noise-reduction units.
This was Akai’s only serious venture into the semi-professional market.

I've owned two of these over the years and was very surprised that it really doesn't record or playback with sound that is any better than your average higher end Japanese machine. It sells for big money because it's quite rare so might be a good item for a serious collector of rarities but if you're looking for performance, best to look elsewhere.
