Many stereo
cassette decks are equipped with a noise reduction system. But not many are
equipped with three. The Technics RS-M236X features: dbx, Dolby C and Dolby B
noise reduction circuitry, offering triple insurance of deck/tape
compatibility.
dbx, Dolby
C, and Dolby B
The
RS-M236X's three noise reduction systems are arranged in a neat push-button
format for maximum convenience, dbx is the most effective of the trhee,
eliminating background tape hiss, and also giving the tape the ability to
reproduce up to a 110 dB difference in
volume levels (the dynamic range of a live performance) dbx reduces noise by at
least 30 dB, below audible levels, and it increases headroom by about 10 dB, so
the tape can reproduce loud music signals without distorting them. The RS-M236X
is also equipped with a dbx disc decoder, so you can experience the same
live-performance realism from the growing number of dbx-encoded LPs as you do
from dbx-encoded tapes.
Dolby B, the
noise reduction system used in many cassette decks and prerecorded tapes, and
Dolby C, an improved version of Dolby B, both reduce tape noise, especially in
the high frequency range where tape hiss is most noticeable.
Microprocessor
feather-Touch Controls with Cue and Review.
Microprocessor
operation gives the feather-touch control panel an impressive array of
conveniences. You can switch from fast forward or rewind directly to play,
without having to touch the "stop" key. And the deck also includes
cue&review functions, so you can locate specific parts of songs by
monitoring the sound during rewind and fast forward. The controls are also
color-coded for extra convenience.
Wide-Range
2-Color FL Meters
This
advanced electronic metering system uses a flourescent display to show both
instantaneous signal input level and the highest peak reached in each 2-second
period. The meter's range extends from -40 dB to +18 dB to cover dbx 's wide
dynamic range.
Automatic
Tape Selector
Forgetting
to set a deck's tape selector can cause distortion, noise, and unnatural tonal
balance - in short, a ruined recording. But tape type selection is automatic in
the RS-M236X, which detects the ID recesses on the back of the cassette and
sets the correct bias and equalization for normal, CrO₂ and metal tapes. The
automatic tape selector's setting is indicated by colored LEDs.
Slider
Controls for Input Level and Balance
The
RS-M236X's dual slider system provides optimum precision in setting recording
levels. For most recording, the master input level slider suffices, adjusting
both the left and right channels together. For such demanding situations as
live recording, the balance slider adjusts left/right channel balance.
