Description
The X300 was the first recorder from Akai to accommodate 10½ ” reels as standard. Earlier models could take the larger reels but needed special outrigger adaptor kits. As the name suggests, the cross-field bias system was employed and in addition, the X-300 had separate record and playback heads.
Other features included: three independent motors, hysteresis synchronous capstan drive, fast forward and reverse at 45 seconds for 1200ft of tape. Large, positive feel metal piano-key button for transport function and an excellent frequency response.
The X-300 was a professional deck and priced accordingly.
