Philips N 7150 - Recording and Playback Features; Cueing (Monitoring); Four-Track System Operation; Microphone Connections

@ The play button (49 sets the tape in motion for playback.
@ For recording, record button 4? and play button @@) should be
pressed at the same time. The indicator beside the record button
will glow to indicate that the apparatus is in the recording mode.
e Using the pause button (9, recording and playback may be
interrupted briefly without the record and play buttons being
disengaged. The pause button itself can be disengaged by
pressing it a second time.
@ By pressing the stop button @3, recording, playback, fast
forward winding and rewinding may be terminated and the corre-
sponding buttons (except the pause button (19) disengaged.
e@ Fast forward winding and rewinding may be undertaken by
pressing fast forward wind button @) or fast rewind button @9.
Cueing (monitoring during fast winding/rewinding)
When monitor selector (9 is in position ‘tape’, the cueing function
is switched on during fast forward winding, fast rewinding and in
the play/pause position.
When cueing during fast winding or rewinding, the recorded
sound is played back at the winding speed, so the recording will
sound strange because of the increase in pitch. Some practice will
soon enable a desired passage to be quickly recognised and
located.
Cueing is also possible in the play/pause position, the reels then
being turned by hand. In this way, a desired point may be located
with great accuracy, for example the start of a word. This is a
valuable feature when splicing together various sections of tape to
form a composite recording.
The level of the cueing signal may be adjusted by turning cueing
volume control @). When turning this control to the left, the tape is
brought nearer to the playback head, which increases the volume
of the cueing signal. When turning this control to the right, the ape
is brought farther from the playback head, which reduces the
volume of the cueing signal.
Four-track system - fig. 4 and 5
This recorder allows four recordings to be made over the full width
of the tape. The four recording tracks lie one above the other. Each
tape can thus take four mono or two stereo recordings (a stereo
recording consisting of two mono recordings).
Stereo - fig. 4
To make two stereo recordings on the four tracks, proceed as
follows:
@ Set track selector @ to stereo ’ST’; both recording level meters
@ @ will now light.
@ Make the first stereo recording, which takes place on track 1
(left channel)and track 3 (right channe).
@ When theright-hand reelis full, transpose the left and right-hand
reels.
@ Leave the track selector (9 set at stereo ’ST’.
@ Make the second stereo recording, which takes place on
track 4 (left channel) and track 2 (right channel).
@ When the right-hand reelis full, all tracks over the full width of the
tape have been recorded. DB
Mono - fig. 5
- To make four mono recordings on the four tracks, proceed as
follows:
@ Set track selector @9 to 1-4’; recording level meter @) will now
lint.
@ Make the first recording, which taes place on track 1.
@ When theright-hand reelis full, transpose the left and right-hand
reels.
@ Leave the track selector (8 set at '1-4’.
@ Make te second recording, which takes place on track 4.
@ When the right-hand reelis full, transpose the left and right-hand
reels.
© Set track selector @ at '3-2’; recording level meter @ ill now
light.
@ Make the third recording,which takes place on track 3.
@ When the right-hand reel is full, tanspose the left and right-hand
4
reels.
@ Leave the track selector (8 set at ’3-2’.
@ Make the fourth recording, which takes place on track 2.
@ When the right-hand reelis full, all tracks over the full width of the
tape have been recorded.
Connections - figs. 1 and 2
For microphones, headphones and connectingleads, see chapter
*Optional accessories’.
Microphones - fig. 1
The unbalanced microphone inputs are designed for the connec-
tion of low-impedance microphones (50-2000 Ohms) fitted with
6.3 mm diameter mono jack plugs, so virtually any type of mi-
crophone, including electret, may be used.
@ Input @2 is for the left channel microphone.
@ Input @3 is for the right chanel microphone.
For mono recordings on one trck (track selector (1 at 1-4’ or’3-2),
the microphone may be connected to either of the inputs, or two
mono signals will be recorded onto the same track.
Headphones - fig. 1
The headphone output socket @ is for headphones ith a 6.3 mm
diameter stereo jack plug and having an impedance between 8 and
2000 Ohms, thus virtually any type of headphone, including elec-
tret, may be employed.
Remote control - fig. 2
Remote socket 27 enables connection of a start/stop remote
control unit fitted with a 5-pole 240° DIN plug, switch contacts to
pins 1 and 5.
For remote control, switch on the ecorder and press the play
button (9 (for playback) or the play button G8 and the recrd button
@ (for recording). The remote control thus allows the tape to be
started and stopped during recording and playback.
Timer - fig. 2
When using the machine in conjunction with a timer which
switches the mains supply, connect the mains plug to one of the
mains outlets from the timer (switching power 23 W minimum).
Press the mains switch © (the apparatus remaining in the
switched-off state) and then the play button 4 (for playback) or
the play button (@@ together with the record button (7 (for record-
ing). Once the starting time set on the timer has been reached, the
recorder will start to play back or to record. Allowance should be
made for the fact that a few seconds will elapse before the
recorder attains the desired tape speed. If the recorder is also
switched off by the timer, the depressed tape transport buttns will
be released. ;
Connecting the recorder to a HiFi-syste - fig. 2
The recorder may be connected to an amplifier, pre-amplifier,
receiver (combined tuner/amplifier), open-reel or cassette
recorder et.
Use a connecting cable with four coaxial phono plugs at each end,
for example: 4822 321 20381, length 50 cm;
4822 321 20382, length 250 cm.
@ Connect the line-in sockets @) ofthe recorder to the tape output ~
sockets (‘tape out’ or ‘rec out’) of, e.g. the amplifier (fig. 2).
@ Connect the line-out sockets @9 of the recorder to the fapeinput
sockets (‘tape in’ or ’rec in’) of the amplifier (fig. 2). EK
Always connect corresponding channels with one another, left to
left (’L or ‘left’) and right to right (’R’ or ’right’).
The line-out sockets @ are also monitor output sockets, which
allow monitoring (source and tape) during recording. Tre line-out
sockets 60 thus deliver an utput signal both during recording and
playback.
Additional monitor sockets - fig. 2
The recorder is equipped with an additional pir of monitor sockets
which are switched in parallel with the line-out sockets @ and
therefore can be used for the same functions as the line-out
