Philips N4450 - Page 4

INTRODUCTION
Your new Hi-Fi Stereo tape recorder/amplifier N 4450 has
been designed with great care and precision to ensure that it
meets the highest standards of quality and versatility.
This allows the recorder to be used for recording purposes
where superior fidelity is required. The built-in powerful
Hi-Fi stereo amplifier assures a perfect reproduction of
these recordings and may also form the basis of a complete
stereo system.
In addition to quality N 4450 also offers versatility: the:
reverse system (recording and playback in either direction)
and several special effects such as multiplay, echo, reverbe-
ration and sound mixing. Moreover, the recorder incorporates
an electric timer which permits the recorder to be started and
stopped in the recording and the playback mode at preset
times.
These and many other possibilities are described in these
Operating Instructions, which we recommend you to read
very attentively.
Part I of the Operating Instructions explains to the more
interested reader how sound is recorded on magnetic tape:
magnetic registration of sound. It provides a better insight
into the operation of the recorder and it also contains inter-
esting details which might open up new application possi-
bilities.
Part II contains the actual Instructions for Use and describes
the operating procedure. If you are anxious to try out your
new recorder, it will suffice to read this part only.
We wish you many hours of listening pleasure with your new
Hi-Fi Stereo tape recorder/amplifier N 4450.
