PRODUCT OVERVIEW
When only the best will do, call on TASCAM's
122mkIII. The 122mkIII is the de-facto
standard for cassette mastering and playback
in studios, broadcast, and live applications,

aspect of the production. The advanced
direct drive motor, Cobalt Amorphous heads,
built in test tones and front panel bias and
gear/clutch coupled record level controls
combine to make the 122mkIII the industry
standard recorder that professionals depend on.

Cassettes produced on the 122mkIII will absolutely be reference
quality. The advanced FG servo direct drive capstan motor provides
very stable recordings, with almost no wow and flutter effects. The
three head design allows the user to listen to the recording from
tape. You won't have to listen to the tape in another pass to make
sure the tape didn't oversaturate. The built in tone generators and
front panel bias controls make adjusting the machine to suit the
specific tape a breeze.

Sound quality is important, but in live productions, there is no take
two. Everything has to work right the first time. TASCAM's
legendary reputation didn't develop overnight; it was the result of
consistent delivery of robust products that never let the user down.
Broadcast Applications - Radio Studios
Let's face it, we aren't always polite when we press PLAY. Radio
stations work 24 hours a day. Three seconds of dead air can cost
you a substantial listener base, with ten seconds losing almost all
of it. The 122mkIII is designed to withstand the beating given by
engineers under pressure. Solid controls with status LEDs offer
immediate intuitive readout of exactly what is going on. Plus, the
parallel in control enables the user to directly interface the
122mkIII with broadcast consoles for event starts or "recording"
warning lights outside the studio.

Parallel Control Notes:
All command controls are labeled as "in" on
the chart at left. The commands are active
when brought to ground for more than 50
milliseconds or longer.
FADER START pin (22) operates as a latched
function. Playback begins when the pin is
brought to ground for more than 50 msec,
and stops when the ground is released for
more than 50 msec.
Tally outputs indicates the corresponding
transport function when the pin is brought
to ground.
