The TCD330
is the top model in the Tandberg range of cassette tape recorders and in many
ways compares favourably with open reel machines; 3 heads, source abd tape
tests, editing facility, 3 motors, completely electronic controlled, remote
control, servo controlled winding, dual-capstan closed-loop tape path, and dual
Dolby.
Features:
Stable tape
transport. Full control over tape movement with exceptionally gentle tape
handling.
Memory
function.
Tandberg
developed input circuits, optimized for minimum noise regardless of source
impedance.
Peak
indicating meters - the only correct way to measure sound level after
equalization. Also indicate playback level.
Editing
facility.
Decoder for
recording Dolbyized FM programmes.
Built-in MPX
filter.
Matched to
all types of good quality tape.
Adjustable
output level.
Automatic
stop for wind and rewind.
Front jack
for stereo headphones.

Tandberg was
the first company in the world to design a cassette tape recorder with a
combination of 3 motors and an advanced tape transport called the dual-capstan
closed-loop system. On the TCD330 we have taken the development a stage further
and included professional features and facilities normally found only on the
most advanced open reel machines. This means that with the TCD330 Tandberg is
setting new standards with the application of advanced technology, professional
facilities and a professional performance for cassette machines.
3 Heads.
Source and tape tests as you record.
This
facility has been normal on open reel machines for many years, but it has been
missing on cassette machines. Teh TCD330 has separate record and playback heads
placed in the tape path where they enable you to listen to the recording as it
takes place, but a fraction of a second after it has been recorded (tape test).
With this facility we have fully expolited the advantage of 3 separate heads
located in the correct places.
Completely
Logic Controlled.
All the
operational modes are logic controlled - including even the cassette eject
mechanism. The control system is an "electronic brain" with
integrated circuits. This corresponds to several hundred transistors and
provides a very compact and reliable design. Regardless of how you use the mode
buttons, the "electronic brain" always ensures that the tape flows
smoothly and is not damaged. The TCD330 has 3 motors controlled by electronics.
The two reel motors are connected directly to the reel spindles while the third
motor controls the capstans. The number of moving parts has been reduced to a
minimum - a big advantage because all mechanism sooner or later wear out and
need adjusting or replacing. The advantages with electronic control of teh
TCD330 are first and foremost, no mechanical time delays between operational
modes and second, all operation times are minimal.
Rapid
Servo-controlled Winding.
The TCD330
winds and rewinds rapidly and has an automatic electronic servo-system
controlling the wind/rewind speed. The design problem is that the tape can
easily be streatched at the ends if the speed and winding power are too great.
We solved this problem by automatically reducing the speed as the tape gets
near the end. So the tape speed is always correct an the tape is never exposed
to powerful tugs when it stops.
Azimuth
Adjustable on record Head.
The critical
stage in the recording process is where the tape crosses the record head.
Correct reproduction of the highest tones is very dependent on the angle
between the tape and the head face. The angle must by 90° to achieve the best
performance. A 10° error will give 6 dB loss at 15 kHz, and 15° error will give
6 dB loss at 10 kHz.
The tape
path is always slightly different from one cassette to another because of small
deviations in cassette construction. So the tape/head angle will not always be
90°. The TCd330 has a simple, built-in head - angle adjustment facility that
allows you to set the head exactly to 90° for any cassette. So you get the best
results from every cassette.
Editing
Facility.
Another
important advantage with the TCD330. because you can go over directly from
playback to record without going via stop, you can edit tapes and clean-up
recording overlaps in a simple, precise way without clicks.
The Dolby B
Circuits.
The TCD330
Dolby B circuits are used for normal record and playback operations and to
record so-called "Dolbyized FM programmes" in stereo. Increasingly
more countries are transmitting stereo programmes on FM using Dolby noise
reduction systems. These programmes are
virtually free from hiss at the transmitter. But to take advantage of this
improvement in the programme quality and to restore the correct frequency
response the reproducing equipment must include a Dolby decoder. The decoder
can be either in the radio receiver or in the tape recorder. With the Dolby
N.R. button in the position "FM" the TCd330 acts as a decoder.
