3.11. TIP-TOUCH KEYS
N 4450 is operated by relay-controlled electronic tip-touch
keys instead of the conventional mechanically-operated
push-buttons. These tip-touch keys respond to a very light
touch, after which they are illuminated.
They also have a ““memory”’, which means that e.g. when
playback is interrupted for fast winding, the relevant start
key remains illuminated, though less bright, to remind you
of the direction of playback.
Another advantage of these keys is for example, during play-
back you may directly press the start key for the other
direction or one of the fast-winding keys, without first
pressing the stop key.
This feature also ensures that when different keys are
pressed rapidly after each other the recorder and the tape
cannot be damaged, as the last command is always carried
out. In conjunction with the convenient slide potentio-
meters for recording level, volume, balance etc. these tip-
touch keys provide for true ease and rapidity of operation.
3.12. Hi-Fi AMPLIFIER
The N 4450 is a combination of a Hi-Fi tape recorder and a
Hi-Fi amplifier. In addition to reproduction of recordings
made with the tape recorder, this stereo amplifier can also
be used for amplifying signals from all other sound sources
connected to it, such as microphone, record player, tuner
etc., thus forming the centre of a complete Hi-Fi installation.
It features a “SCRATCH” (noise) and RUMBLE filter and
also a physiology circuit (“PHYS”) which boosts the low
and high tones with respect to the mid range.
The controls for volume, balance, treble and bass are con-
veniently operated slide potentiometers. When you wish
to use the amplifier section only and the recording section
is not needed, you can render the tape transport inoperative
(thus preventing unnecessary wear) by setting the
function selector (12) to “AMP”. The amplifier supplies
2x 20 Watts continuous power (2 x 30 Watts music power)
and is provided with connections for loudspeaker enclosures
with an impedance between 4 and 8 ohms.
3.13. SPLICING JIG
Acces to the jig for editing and splicing the tape (Fig. 9) may
be gained by removing the cover below the tape slot in a
forward direction.
This built-in splicing jig consists of a guide slot for the tape,
two tape clips and an oblique guide slot for the anti-mag-
netic tape cutter. It has the advantage that the tape can be
edited with the reels normally placed on the turntables.
A very useful aid in tape-editing is the Philips’ splicing kit
SK 10 (optionally available).
3.14. REMOTE CONTROL
All tape transport functions plus the recording function can
also be remote-controlled with remote control unit N 6719.
This remote control unit is an optionally extra available
and has a lead of approx. 7 m length. The tip-touch keys on
the remote control unit correspond to the tip-touch keys on
the recorder (keys 16 ... 22). The keys on the remote control
unit are also of the tip-touch type, which illuminate when
operated and have a “‘memory’’. When the remute control
unit is connected, the remote-control keys and those on the
recorder can be used side by side. The unit is supplied with
a mounting bracket which enables the unit to be attached
to a cabinet, an easy-chair or a wall.
3.15. CONTINUOUS TAPE REEL
The tape recorder can be used in conjunction with a conti-
nuous tape reel type EL 1907/52 (CE 10). A programme
recorded on this continuous tape reel can be played back
continuously as the endless tape repeats itself indefinitely.
The continuous tape reel may be used, for instance, to
repeat commercials in department stores and supermarkets.
3.16. SLIDE SYNCHRONISER
In the horizontal position of the recorder, it can be used in
combination with slide synchroniser N 6400.
This unit allows slides to be synchronised with speech and
music.
3.17. TELEPHONE COIL
With the aid of telephone coil N 6708 (not available in Great
Britain), you can record telephone conversations with this
recorder. The telephone coil is then connected to the
recorder in a similar way as a microphone. In various coun-
tries, however, recording of telephone conversations is not
permitted by law. Therefore, should you wish to do so, we
recommend that you first ask for advice.
