Philips N4506 - Recorder Features and Connections; Dynamic Noise Limiter (DNL); Connections Overview

memory stop is not operative during recording. By
setting the counter to 0000’ when a recording is
commenced, the beginning of this recording can,
later, be swiftly located by pressing memory switch
@Q and then rewind key The memory stop is
switched off by pressing switch @9 again.
Fast winding/cueing
The wind speed can be varied, during fast winding
and rewinding, by means of control 67).
When function selector 68 is in its lower position,
cueing is made possible, during fast winding, by
moving cueing knob @§) to its upper position; this
causes the tape to be held against the playback
head. The recorded sound is played back at a
speed that is controllable via wind speed control @)
and, with a little experience, particular parts of
recordings can soon be recognized and thus,
quickly located. Note: Do not leave the cueing
knob in its upper position unnecessarily.
When switching from one tape travel function to
another (e.g. fast rewinding to start), it is not
necessary to depress the stop button first. The
pause button @) does not operate during fast
winding. When function selector 68 is in its upper
position, start key does not operate; fast
winding and rewinding is possible but without the
cueing function.
Dynamic Noise Limiter - DNL
The DNL suppresses tape noise without greatly
affecting the naturalness of the music signal. It
operates only during quiet passages and in the
absence of signal on the tape, which is when noise
is most apparent. The DNL operates during play-
back and during monitoring with monitor selector
at ’A’. Thus recordings being made on this
recorder are entirely unaffected by the DNL. The
DNL is operated by switch 69; indicator 6) lights
when the DNL is switched on.
Connections
The recorder is fitted with DIN standard connec-
tion sockets. Equipment fitted with DIN connection
sockets can be connected to the recorder using
lead 4822 321 20207 (EL 3768/14). For the con-
nection of equipment and accessories fitted with
other than DIN plugs or sockets, adapter leads and
plugs are available from your dealer.
In the interests of safety, consult your dealer if you
wish to connect equipment not having a recorder
connection socket (e.g. a TV-set).
@ Socket 6): output for stereo headset. With the
groove in the headset plug opposite '+’ the
MFB-loudspeaker enclosures remain switched on.
With the groove opposite ’—’ the MFB-loudspea-
ker enclosures are switched off.
@ Socket 6%: input for stereo microphone or for
the left-hand channel mono microphone when
making stereo recordings with two microphones.
This socket also serves as an extra input for a
radio, amplifier or second recorder. The recording
level (also when using the unit as a control
amplifier) is adjusted with control and, when
using a stereo sound source, with the controls
and 62.
@ Socket 6: input for the right-hand channel
mono microphone when making stereo recordings
with two microphones. The recording level (also
when using the unit as a control amplifier) is
adjusted with control 62.
@ Socket @: input for record player. Switch
must be in its upper position when using a non-HiFi
pick-up cartridge (crystal or ceramic); in its lower
position the pre-amplifiers are switched in for a
HiFi pick-up cartridge (magnetic or HiFi-ceramic).
For record players with a built-in pre-amplifier,
switch must be in its upper position. Record
players with built-in output amplifiers must be
connected to socket € or
@ Socket @): auxiliary input for radio, amplifier,
recorder, combined gramophone/amplifier or
electronic organ.
@ Socket ۤ: tuner input. Radios and combined
tuner/amplifiers can be connected to socket 6% or
@ Socket €9: combined input/output (record and
playback) for all equipment - radios, amplifiers,
combined gramophone/amplifier and tuner/ampli-
fier systems, tape and cassette recorders - fitted
with a recorder or diode connection.
@ Socket @0: contro! amplifier output for MFB-
loudspeaker enclosures. The input sensitivity
control on the MFB-loudspeaker enclosures
should be set to ‘1 V’.
@ Socket @): monitor output for amplifier (allowing
listening-in during recording) or for a second
recorder (allowing simultaneous recording by two —
recorders). The monitor socket provides an output
signal during use as a control-amplifier and both
during playback and recording, except when the
recorder is in the record/pause position with
monitor selector @) in position ’A’.
@ Socket @: socket for remote control unit, by
which the tape can be started and stopped during
recording and playback. When the remote control
unit is employed, pause key @ must always be
pressed, either together with start key for
playing back or with start key @4 and record key
for recording.
