FEATURES
AUTOMATIC SILENT-LOADING
MECHANISM
The use of an optical cassette detector and shift mechanism makes
possible easy-to-operate auto loading and power eject. In addition,
thorough attention has been paid to all aspects of construction, from
selection of materials for motor
drive transmission
parts, to final
assembly, in order to assure that the mechanism operates as silently
as possible.
MOL BALANCE CONTROL TYPE AUTO BLE
Differences in the. frequency spectrum of the music source changes
the AUTO BLE bias adjustment point in 3 stages. This allows a flat fre-
quency response and dynamic range at the maximum limits allowable
with tape.
AUTO BLE: An abbreviation for Automatic Bias, Level and Equalizer
Tuning System.
MOL: An abbreviation for Maximum Output Level.
AUTO MONITOR
For simplified operation of the bothersome monitor switch during
recording, This feature allows you to. switch between tape monitor
and source monitor merely by pressing the operating switch.
FEATHERTOUCH, EASE OF OPERATION
WITH IC LOGIC
The unit is a joy to operate, with sure, microcomputer digital feedback
servo controller mechanism, allowing direct transition from playback
to fast forward, rewind.
TAPE SLACK PREVENTION FUNCTION
With the tape slack prevention function, when the cassette holder
closes, the takeup reel automatically revolves to eliminate any tape
slack.
DOLBY NR B, C SYSTEMS
In addition to the previous Dolby B noise reduction system, the unit is
equipped with the Dolby NR C type system and its superior noise
reduction effect for even greater fidelity of sound reproduction.
MPX FILTER
Using the Dolby NR system, the MPX filter can be switched to ON or
OFF for more effective noise reduction with FM stereo broadcasts.
AUTO RECORDING MUTE FUNCTION
The automatic recording mute function creates a non-recorded inter-
val of 4 seconds at one touch, then automatically returning the unit to
the recording standby mode. This function is very convenient for cut-
ting out commercials and unwanted narration during FM broadcast
recording and editing.
BUILT-IN MUSIC SEARCH FUNCTION
The music search function is convenient for locationg a particular pro-
gram on a tape, or when performing repeat piay of a certain program.
DUAL MGDE COUNTER
The four-digit digital display can be used either as a real time counter
for displaying the time remaining on the tape, or as a normal tape
counter display.
TIMER FUNCTION ALLOWS ABSENTEE
RECORDING OR WAKEUP PLAYBACK
When used with an optional audio timer, you can wake up to your
favorite music, or perform automatic tape tuning and recording start.
The AUTO BLE timer recording function gives you more freedom for
recording.
CLOSED LOOP, DUAL CAPSTAN DRIVE
This mechanism drives the tape using two sets of capstans and pinch
rollers. Tape travel is greatly stabilized in order to shut out any ex-
ternal vibration. Wow and flutter, and modulation noise is reduced,
letting you enjoy even greater clarity of tone. In the capstan a quartz
PLL D.D. motor is used, the reel motor is a super-low torque ripple
coreless type.
THREE-HEAD SYSTEM USING RIBBON
SENDUST HEADS
Since a 3-head system, using independent recording, playback, and
erasing heads is used, you can monitor the playback sound while
recording, thus allowing you to check the recording status. Ribbon
Sendust, developed through Pioneer's own magnetics technology, is
used in the combination recording/ playback head, while anoxic cop-
per windings are used in the playback head, and the erasing head uses
a special alloy with high efficiency for small window use. As a result,
the full performance of high-output tapes, including metal tapes, is
fully demonstrated,
delivering the dynamic energy of sound with
superb sound quality.
DC AMPLIFIER
A DC amplifier,
with superb tone and phase characteristics and
dynamic range is used for the playback equalizer amp. The first stage
is a low noise dual FET differential 2-stage type amp, while the power
section is a shunt type + 2 power unit composition.
