Topaz D202. Unfortunately, I almost do not know anything
about this recorder, who ordered this development, and
who really used it. He probably did not have any
purpose, and could use it anywhere, in editorial
offices, libraries, police, the KGB, and other
organizations. For example, Alexey Afonasov, who gave me
this recorder as the leading engineer of NIKIET, used it
as a computer drive . For such purposes, it is really
well suited, since the management of modes is completely
electronic. The presence of an adapter for recording
from the telephone line provides other additional
possibilities for its use.
The recorder has a good set of functions. In the
microphone there is a switch of the main modes -
recording, stop, playback, rollback. The microphone can
also be used as a speaker, although there is a normal
0.25 W speaker in the recorder. Recording is performed
from a microphone, telephone adapter, or from a line
input. Playback is made to the line-out,
microphone-speaker, standard speaker, or earphone TM-2.
Also on the microphone there is a LED indicator for
recording and discharging the batteries. It is possible
to control from the foot controller.
The recorder has volume, tone, rollback, and slow
playback speed controls. When the tape ends or breaks, a
beep sounds, but there is no hitchhiking. The recorder
is powered by 6 batteries type C, or from the power
supply unit BP12 / 5 through the matching unit.
The device is really very convenient and functional, but
for all this in 1985 it was necessary to give 590
rubles. The circuit of electronics is rather
complicated, and in general the recorder does not look
like an outspoken Soviet consumer goods, it is made from
fairly neat. My voice recorder and now it's working
fine, repair was not needed. In kinematics, 2 engines
are used, one of which controls the mechanics of
switching modes, and here, too, everything is working
fine.
