Hitachi
D-E55
Microcomputer-Controlled Cassette Deck with Metal-tape Compatibility, Feather- Touch Controls, Auto Rec
Mute Function, and Dual 12-LED peak Meters.
The first
thing that will impress you about the D-E55 is that it has the look and feel of
a precision instrument. The handsome styling and the incredibly smooth
operation provided by the built-in microprocessor and power-assisted
feather-touch controls are unexpectedly luxurious considering the D-E55's
accessible price tag. A large number of computer-controlled automatic functions
have been incorporated, too - for exceptional flexibility and convenience. You
get Auto Rec Mute, Auto Rewind Play/Stop, Computerized memory Rewind, Timer
Play/Record, and provision for optional remote control.
Naturally,
the D-E55 also gives you the greatsound Hitachi is famous for.. It's metal-tape
compatible, and there's a 4-position tape selector switch to get excellent
performance with any find of tape. Dual 12-LED peak level indicators permit
accurate setting of recording levels.
Microcomputer
Control
Conventional
tape decks use mechanical linkages to engage the mechanism when you push the
transport controls. These can eventually cause alignment problems, particularly
if too much force is used. Also, a mistake in operation such as pushing fast
forward instead of stop when the tape is
rewinding is liable to stretch the tape or damage the transport. The D-E55's
microcomputer control ends thaes problems by intelligently managing all
functions, gliding the transport into position at the proper time with just the
right amount of force. What's more, all controls are feather-touch and can be
switched directly from mode to mode without the need to push the stop button.
The microprocessor also controls a variety of automatic functions.
Computerized
Memory Rewind
Unlike
ordinary memory rewind systems which rely on the tape counter to specify the
desired stopping point on the tape, the D-E55 system uses the microcomputer to
memorize the position of the tape when the Play button is pressed, allowing to
rewind to the that point at any time. When the Memory rewind Play mode is
selected, the tape begins to play after being rewound, very convenient for
listening to a particular selection a number of times. Memory rewind is also a
big help when recording; to re-recorded after having made a mistake, use memory
rewind stop to return to the exact position you started at.
Auto Rewind
Play/Stop
This handly
feature adds a lot to operating convenience. In the Stop mode, the tape is
automatically rewound when the end is reached and the transport is shut off- no
need to waste time rewinding it later. In the play mode, the tape is
automatically rewound at the end, the Play function is re-initiated so you hear
the same side again until you stop it manually - ideal for continuous
background music.
Auto Rec
Mute
Still
another feature made possible by the microcomputer, Auto Rec Mute makes taping
easier and gives better results. One touch of the Rec Mute button and a
4-second section of blank tape is automatically made, the ideal waay to place
intervals of silence between the selections on your tape. Intervals other than
4 seconds may also be made by using the pause button in combination qith the
Rec Mute button. The pause indicator flashes once a second to help measure the
exact time desired.
LED peak
Meters
Instead of
the usual machanical VU or peak meters, the D-E55 offers dual 12-LED peak
indicators driven by advanced digital circuitry. Since there are no moving
parts,, these meters do not suffer from delay or overshoot like their
mechanical counterparts, and therefore provide accurate, instantaneous visual
monitoring of signal levels.
You'll
really appreciate how easy these meters make it to set precise record levels
for top-quality recordings.
4-position
Tape Selector Switch
A large
variety of recording tapeare available
on the market, with widely varying characteristics. It is essential that the
deck be matched to the particular type of tape in use ifideal results are to be
obtained. The D-E55 has switch settings for metal, CrO₂, Normal, and FeCr
tapes, giving you optimum results whatever tape type you use.
