Description
The Top of the consumer line Teac A-7300, was similar to the A-7300RX and 25-2 both semi-pro machines. Essentially the same as its more sophisticated brothers but without the separate amplifier unit with the dBx noise reduction system. Specifications were very similar to the A-7300RX when not in dBx mode.
Available in quarter-track stereo (A-7300) and half -track stereo (A-7300-2T) versions, prices when new (in the UK) were £849 and £862 respectively. Unlike previous Teac models, the A-7300 has all logic circuitry in the transport for more efficient movement through the functions.
Quarter-track stereo (A-7300) 3 3/4 – 7 1/2ips features a uniform wind which is a slow rewind for storing your tapes.
Half -track stereo (A-7300-2T) 7 1/2 – 15ips did not have uniform wind but substituted with an edit function and memory rewind.
The A-7300 has a direct-drive capstan motor, delivering great performance and has proven pretty reliable, but some reports suggest that it has the potential to develop difficulties, so you will need to find a replacement somewhere, not likely from Teac. Eddy current induction reel motors for high efficiency and accurate tape tensioning.
With a built in mixer you can record from 4 microphones or 4 lines, or 2 mics and 2 line inputs. Great for live recording.
Separate master input level control for all mic/line inputs.
Edit switch deactivates the take up reel motor allowing you to edit out unwanted sections of tape.
Cue function – so you can easily locate musical passage in either wind mode or play mode.
Tape-source and tape only outputs for added flexibility to create special effects like echo, cross echo or sound on sound.
Comparing at the electronics of the 7300 to later Teac high end models, it’s a shame the company started cost cutting in this area as an X-2000 shows far less investment in the electronics.
