PRODUCT HISTORY

THE 122mkIII ADVANTAGE

The 122mkIII has long been revered as the standard for cassette mastering, with few changes made to the original product design.

The original 122 cassette deck was introduced in 1980. The 122 was TASCAM's first professional, rack mounted, 3 head cassette deck with 2 speeds (1 7/8 and 3 3/4). A year after the product was first introduced, NBC standardized their entire operation using the TASCAM 122. The reason NBC made the change was because the 122 had all the capabilities for adjustments, and spectacular performance characteristics. Aided by NBC's practical endorsement of the TASCAM 122, ABC and CBS followed, and before long the 122 became the industry standard.

In 1987 the 122MKII continued TASCAM's leadership in the professional cassette market. The new features included Dolby HX PRO, the ability to find locate points, a zero return function, and pitch control.

The 122mkIII was introduced in 1993 incorporating a new and improved transport assembly utilizing the Hysteresis Tension Servo Control System, further improving the reliability and stability of the legendary 122 heritage.

Not all cassette decks are created equal. While most cassette decks offer Dolby Noise Reduction of some sort, here are some features you won't find on most run-of-the-mill cassette decks:

Balanced, Unbalanced, and Front Panel Line Connectors - Integrate into any studio, anytime. The rear panel I/O accepts both balanced and unbalanced signals, and a front panel Line In provides simple patching of ancillary gear for reference copies, submixes, or spontaneous dubs.

2 Locate Points and Return To Zero - Locate points can be used for comparing multiple mixes in quick sequential order, or for marking cues. Return To Zero is always handy when recording multiple passes.

Dolby HX Pro - HX Pro algorithms help maintain true printing of high frequency content. HX Pro recordings do not require any decoding on playback, so the user can freely apply this system to their recordings.

MPX Filter - When recording from FM broadcast, Dolby Noise Reduction can sometimes be compromised by information around the pilot tone at 19kHz, or the sub carrier note at 38kHz. The MPX Filter removes these troublesome frequencies.

Oscillators, Front Panel Bias & Recording Level Controls - Each brand of tape responds to recordings differently. Adjusting the bias controls on the recorder can help compensate for this. The 122mkIII's three head design allows for real time monitoring of the test tones as they are adjusted. For additional convenience, the test tone oscillators are built right in, so there's no extra test equipment to track down. Front panel bias and recording level controls make biasing the 122mkIII effortless. Proper bias settings will result in more reliable sonic characteristics in most situations.

ARCHITECT'S SPECIFICATIONS

The cassette player/recorder shall utilize a three head cassette mechanism, using separate heads for erase, record, and reproduce. The transport shall be a direct drive mechanism and employ the Hysteresis Tension Servo Control System for increased stability.

Inputs and outputs shall be provided on unbalanced RCA and balanced XLR plugs on the rear panel. An additional pair of 1/4" inputs shall be located on the front panel.

Levels shall be displayed on large VU meters with peak LEDs for accurate display of levels. The input level shall be controlled by large gear/clutched controls on the front panel. Stereo output level shall also be provided on the front panel for convenience. Headphone output with level control shall be provided on the front panel.

Monitor selection switch shall be provided on the front panel for selection between input monitor mode and automatic monitor mode. Dolby™ B and C noise reduction shall be implemented and switched from the front panel. An MPX filter shall be switchable from the front panel.

A pitch control will provide approximately ±12% range of pitch control, with a dedicated on/off control.

Individual bias and level fine tune controls shall be accessible on the front panel, as well as 400Hz and 10kHz oscillators for convenient biasing of the machine.

The cassette deck shall have dedicated buttons to access the RTZ function (Return to Zero) and two locate points. An additional separate button shall trigger the repeat function which will loop between locate 1 and locate 2.

A digital counter shall be used to display precise tape location with a readout displaying minutes and seconds.

A parallel control shall be provided which can be used for remote control and tallies, and it shall be compatible with the TASCAM RC-134 remote control.

The cassette deck shall mount in a standard 19" rack mount form, taking three rack spaces. The cassette mechanism shall have dimensions of 19" x 5 1/4" x 14" (W x H x D).
