Tascam 112mkII User manual

Rugged, Cost-Effective 2-Head
Transport For Smooth, Faultless
Tape Handling
The 112 MKII is equipped with TASCAM’s rugged,
conventional 2-head design. The reliability of this
system is well-documented among recording pro-
fessionals, who vouch for its superior stability and
reliability.
Automatic Tape Bias Selection
For Error-Free, Optimal High
Frequency Response
Proper bias type is automatically selected when a
tape is placed in the deck; you get optimal record-
ing and playback response with Normal, Metal or
Cr02tapes.

Sound Price/Performance
For Basic Mastering
TASCAM designed the 112 MKII stereo cassette
deck to offer musicians and production studios
alike a cost-effective cassette production/
mastering deck. The 112 MKII is a basic, 2-head
no-frills “workhorse” that offers outstanding per-
formance, stability and reliability for any number
of basic recording applications; tape mastering,
dubbing from external decks, and radio program
archiving. Still, it boasts a robust feature set that
is geared toward producing high-quality tapes
with optimal signal levels and high frequency
detail.

These intuitive controls allow editors to select two
points on any tape for one button forward/reverse to
wherever the action is. Once the two points are set,
the REPEAT button allows you to loop between the
two points with one-touch convenience.
Additionally, Return-to-Zero (RTZ) quickly spools
the tape back to 0000 on the 112 MKII’s four-digit
index tape counter.
Easy Integration Into Personal,
Project & Production Studios
The 112 MKII features rear-mounted RCA input
and output jacks for easy connection to audiophile-
quality sources.
Optional Balanced Connector Kit
If your input requirements include balanced or
unbalanced XLR connectors, the optional LA-112
connector kit will provide the additional inputs. After
a simple installation procedure that requires no
special tools, both balanced and unbalanced line
inputs and outputs will be available, selectable with
the flip of a back-panel switch.
Parallel Port For External Control
For hands-off mastering in professional recording
environments, you’ll find a 25-pin D sub connector
on the 112 MKII back panel. This link connects the
tape deck to the optional RC-134 remote control unit
or for fader start from any mixer that also uses the
25-pin D sub protocol.
Stereo VU Meters & Input/Output
Dials Ensure Optimal Sound Levels
The input dials on the 112 MKII are gear-interdepen-
dent, allowing you to dial in stereo VU calibration with
one dial. Or, for channel-specific calibration, hold one
dial still while adjusting the other. Either way, you get
consistent, cleaner, more dynamic mixes.
Dolby HX Pro For Highest
Quality Without Distortion
For maximum high-range clarity and reproduction
precision, the 112 MKII is equipped with the Dolby HX
Pro headroom extension system. HX pro is an active
biasing system that minimizes the effect of high fre-
quency 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 112 MKII also utilizes 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 112 MKII offers two Autolocator
buttons (LOC 1 and LOC 2) and a MEMO IN control.
