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, and with good reason. Few products receive this much attention to detail during every 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.

   Duplicating System:
Duplicating System
Model: DM-DC
$Call
This duplicator is a modular system which provides for efficient, safe copying to standard cassette format original evidence tapes from Micro-Cassettes, stereo Sony NT-2 and MZ-N1 digital recorders, Nagra SNST and JBR. Because the original recordings are often longer than the tape being copied onto, the system provides for automatic, unattended operation without the need to program the system for the length of the original or copy.

The T-202/DC is a special proprietary version of the Tascam 202MkIII recorder. It is a two speed dual well machine which will produce two simultaneous copies and provides all the necessary control circuits to automatically start and stop the source playback machine. The T-202/DC can also make additional copies from cassette-to-cassette at double speed.

   Marantz Modification - Recorder Enhancements:
marantz recorder
Model: MRC/SS
$Call
The MRC/SS circuit provides three functions in one package.

First, an efficient (low power drain) remote control allows the recorders to be started and stopped by computer logic, relay contacts, or a simple switch. In remote control stand-by the MRC/SS draws about 150 µAmps, less power than the self-discharge of most batteries (about ten years) and in operation imposes a burden of less than one percent of normal battery life. A standard Marantz PMD-201 in remote stand-by will drain a fresh set of batteries in less than one day and a PMD-430 has no remote control facility at all.

The second function is a "Silent Stop" at the end of tape. A standard Marantz recorder has a solenoid which makes noise when it disengages the "Play" and "Record" keys at the end of a tape. In the event that the recorder is located near the subject of an investigation this noise could be heard.

Finally, the MRC/SS provides power to the type of electret microphones which are widely used by law enforcement agencies. It is especially useful with model LV-7 microphones when used in motor vehicles, aircraft, or boats.
