(HTSC) system. This high-tech servo control system maintains consistent back tension on the tape all through the reel, combatting inconsistencies brought on by tape shift & extreme temperatures and humidity. Front-Access Bias & Level Calibration Controls For full control of bias levels when recording material with critical high frequency components, the 122 MKIII offers Bias and Level fine tuning for each channel. These fine tuners can be used in conjunction with the 400 Hz/10 kHz calibration oscillator button (OSC) to get proper VU calibration before or during each record- ing session. Proper bias type is automatically selected when a tape is placed in the deck; then, with a few turns from the front panel, even more precise bias and level tuning can be dialed in for both the left and right channels. Stereo VU Meters and Input/Output Dials Ensure Optimal Sound Levels The input dials are gear-interdependent, allowing you to dial in stereo VU calibration with one dial. Or, for channel-specific calibration, hold one dial while adjust- ing the other. Either way, you get consistent, optimal recording levels without distortion. Dolby HX Pro Headroom Extension For maximum high-range clarity and reproduction pre- cision, the 122 MKIII is equipped with the Dolby HX Pro 122 MKIII 3-HEAD STEREO CASSETTE DECK page 1 of 4 The Sound Choice For Sound Production Facilities The TASCAM 122 MKIII is the flagship of the quality TASCAM tape deck line. Extremely high standards of reproduction quality and overall performance earmark this system: Cobalt Amorphous record and play heads, independent head azimuth adjustment, precision FG servo direct drive capstan motor and uncompromised electronics. All this in a studio-ready, 19, 2-unit rackmountable package that immediately finds a home in any sound production environment: from cassette mastering recorded material to radio broadcast production to masters of audio/visual and multimedia soundtracks. Smooth, Faultless Tape Handling Mechanisms The 122 MKIII features a three-head transport with separate high-performance record and playback heads, manufactured from resilient Cobalt Amorphous materials. The three independently-oper- ating heads, combined with precision FG servo direct- drive capstan motors, combine to provide the highest standards of reproduction quality and performance — frequency response as great as 25 Hz to 20 kHz, and less than 1% total harmonic distortion. To virtually eliminate wow and flutter, the 122 MKIII is equipped with the Hysteresis Tension Servo Control 13 (330 mm) 1 (20.5 mm)1/4 (5.8 mm)19 (482 mm) 5 3/16 (132 mm)

Additionally, Return-to-Zero (RTZ) quickly spools the tape back to 000 on the real-time Tape Counter. Easy Integration Into Project & Production Studios The 122 MKIII features balanced and unbalanced inputs and outputs, selectable with the flip of a back-panel switch. On the front panel, 1/4 inputs allow simple, direct plug-in of line-level gear. Parallel Port For External Control For hands-off mastering in professional recording environments, you’ll find a 25-pin D sub connector on the 122 MKIII back panel. This connects the tape deck to optional RC-134 remote control unit or for fader start from an external mixer that also uses the 25-pin D sub protocol. headroom extension system. HX pro is an active biasing system that minimizes the effect of high frequency music signals on the deck’s bias signal, achieving up to 6 dB greater headroom at the higher music frequencies. What’s more, HX Pro is a record- only process, so tapes recorded with HX Pro can be played back on any other cassette deck. The 122 MKIII also engages your choice of popular Dolby B or C noise reduction when recording, to further position your tape for best results from other playback decks. 3-Point Memory Features Speed Editing/Review When editing program material or engaging in critical listening, the 122 MKIII offers two Autolocator buttons (LOC 1 and LOC 2) and a MEMO IN control. These intuitive controls allow editors to select two points on any tape for one button forward/reverse to wherever the action is.
