TEAC A-7030


Teac A-7030U Stereo Tape Deck.
An all-solid-state. Single-direction, 2-track record/playback7erase, plus ¼-track playback stereo tape deck. The A-7030 is designed for the demanding professional or the discriminating
audiophile. This superb deck has a capacity up to the 10½" NAB reel size and operates at 15 or 7½ ips, with performance comparable to that of the finest professional sound studio equipment.
Wow and flutter are an exceptionally low 0,05%, frequency response is 30 to 20,000 Hz and the
signal-to-noise ratio is a high 58 dB. The unique TEAC Proline ™ hyperbolic heads, a massive inertial flywheel for tape travel stabilization and the rugged, precise TEAC 3-motor transport ensure the utmost in sound quality. Operation is fast and always under your control with our symmetrical touchbutton control system and solenoid/reley actuators. The A-7030 includes

instant off-the-tape monitoring, mic-line mixing, pushbutton high speeed cueing and automatic rewind and shut-off. Options such as a full remote control and floor-standing wooden console make it even more versatile.
