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.
