The K-112 is
a three-head, double Dolby configuration that allows monitoring of the
"just-recorded" signal, while the recording is belong made. This cassette deck is specially designed with a
superb "single-direction" transport to ensure professional-grade
recording.
This 3-head
stereo cassette deck utilizes the latest in refined technological features.
Some are as follows: Hard Hexalam
permalloy 3-head system; two motors; Dolby HX-Pro; Dolby B and C; feather touch
full logic transport controls; four digit electronic tape counter with memory; fine Bias control;
Luxman System remote control capability, and more.
Hard hexalam
permalloy 3-Head full monitoring configuration
The hard
anti-wear surface, plus the laminated hexalam low eddy current core, give high
unsaturated recording levels coupled with low loss, long life performance. In
addition, the Hexalam designm coupled with OFC windings inn the R/P head,
result in linear current flow and uniform magnetic flux inn the gap for purest
sonic quality. Of course, 3 head allow full tape monitoring capabilities.
Two Motor
Drive System
Separate
capstan and reel drive motors ensure lowest possible wow and flutter,
particularly over the long term. Variations in cassette friction or reel drive
irregularities, have no effect on the precision of capstan rotation.
Dolby HX-PRO
This
headroom extension system, developed for professional applications, greatly
increases high frequency headroom for wide range dynamics without saturation.
Operating in the record mode only, it automatically reduces bias in the
presence of high level high frequency program material, while simultaneously,
and automatically, adjusting the E.Q. dynamically to provide precise even
frequency response. High frequency distortion is thereby greatly reduced and is
especially effective when using normal (Fe) and high bias ( Co, CrO₂) tapes.
Fine Bias
Control
Allows
precise adjustment of tape bias for optimization of frequency response. Such
adjustment permits one to compensate for variations in tape formulations when
using different tape brands or for production variations within the same
brands. It is especially useful with the 3 head system.
4-Digit
Electronic Counter with Memory
While
functioning in the same manner as a mechanical counter, this electronic counter
offers more precision while completely eliminating the drive and wear problems
of mechanical counters.
Low velocity
Tape Head Engagement System
This motor
driven cam engagement mechanis, smoothly pulls up the head assembly at low
velocity to engage the tape cassette. This eliminates the hard jar and slap of
solenoid systems, thus preventing the loosening or distortion of precision head
alignments.
Feather
Touch Full Logic Transport Controls
Transport
control push-buttons, requiring only a light press, activate the computer
controlled logic system for instant response of the transport to operator
commands.
System
Remote Control Capability
When used
with Luxman's system remote control centers or receivers, such as the U-100,
F-105, R-115, R-117, etc., the K-112 can be operated romotely, along with other
Luxman components in the system, with one unified hand held remote controller.
