is then set up to record, releasing the PAUSE key permits actual re-
cording to start immediately after completing the level test.
Before commencing to record, it is always advisable either to note the
counter index number or to press the zero reset button in order to
facilitate location of the beginning of the recording upon later tape
rewind or playback (see sec. 3.18).
Once all of these steps have been completed, the input source to be
recorded should be faded in via the master control (5) and, using level
controls© and ® or (3) and 0 .adjusted for maximal record level at the
loudest passages (see sees. 3.1 to 3.4). The peak level limiter © may
then be switched in-circuit (see sec. 3.5), and releasing the PAUSE key ®
(to up-position) will start actual recording. By switching the MONITOR
switch ® (see sec. 3.7) from TAPE to SOURCE, you may also acousti-
cally judge the quality of the recording. Headphones must be connect-
ed as described in sec. 22 (for their volume regulation see 3.17), or
monitoring must be through the loudspeakers of your sound system
(see sec. 5.1).
5. Playback Operation for True Audio
Enthusiasts
5.1 Playback through Hi-Fi Sound System Amplifier
Amplifiers with DIN socketry should be connected to the RADIO socket
of the SG 631 LOGIC via UHER Stereo Lead K 541.
Amplifiers with phone sockets may be connected to the RADIO socket
of the SG 631 LOGIC via UHER Lead K 551. On the sound system
amplifier use the left and right tape inputs. Before connecting up the
equipment, note the lead end markings: yellow for the left channel, red
46
For playback the MONITOR switch ® on the SG 631 LOGIC must be
in TAPE position. Set volume, tone and channel balance in accordance
with the operating instructions for your amplifier. The playback (or out-
put) signal delivered to the RADIO socket may be raised or lowered
by turning the OUTPUT LEVEL control @ . Thus the tape recorder sig-
nal may be adjusted to permit switching to other input devices (like
a record player) connected to the amplifier without a change in volume
(see also sec. 3.20).
If your amplifier is equipped with a monitor input, the input may be used
for monitoring as described in sec. 6.2.
5.2 Playback through Stereo Headphones
All high or low impedance stereo headphones with an impedance
between 8 and 2,000 ohms may be connected directly to one of the
two headphones sockets if they are equipped with 5-pin plugs. Head-
phones with LS-7 plugs require UHER Adapter K 633 for connection to
the sockets. To connect stereo headphones with jack plugs, you will
need special adapters which are available at audio dealers' everywhere.
When using these adapters, you may find that the playback of a stereo
recording is monophonic. In such case, pull the 5-pin plug of the adapter
out of the headphones socket and turn it 180° before re-plugging it
into the socket.
The volume may be regulated by turning the headphones volume con-
trol © as described in sec. 3.17. The output signal (which may be ad-
justed with this control to approximately 1.5 V per channel) delivered
to the headphones socket permits connecting self-energized loud-
speakers which achieve particularly high acoustic output. Self-energized
loudspeakers should be connected the first time by your audio dealer
or an audio technician.
