6.1 Transcribing onto Another Tape Recorder (Dubbing)
Without having to alter stationary connections to your sound system,
recordings may be copied onto another open-reel (or cassette) re-
corder by using the DUBBING socket. UHER Stereo Lead K 541 should
be used to connect the SG 631 LOGIC to the RADIO socket of the other
recorder. (The output level control @ does not affect the dubbing
output.)
6.2 Monitoring via the MONITOR Output
use the system's loudspeakers for acoustic monitoring of your recording
by connecting the MONITOR socket of the SG 631 LOGIC to the MONI-
TOR input of the amplifier (UHER Stereo Lead K 541 will be needed).
Switching for off-tape or from-source monitoring may be accomplished
either from the tape recorder or from the amplifier. When switching from
the tape recorder, the monitor switch of the amplifier must be pre-set
for off-tape monitoring. On the other hand, to use the amplifier's switch
to select the mode of monitoring, the monitor switch of the SG 631 LOGIC
must be in TAPE position.
6.3 Sound for Slide Shows
Sound for a slide show and the control pulses that trigger slide change
should be recorded separately. When working with the half-track tape
head assembly (Z 401), only monophonic recording is possible as the
6. Further Hints and Tips
control pulses must be recorded on the lower track (see Fig. 4 "SLIDE +
MONO") of the tape. Moreover, during playback through the power
amplifier of a hi-fi system the volume of the control track channel must
be turned down to zero in order to render the 1 kHz control pulses
inaudible. On the other hand, if the quarter-track tape heads (Mount
Z 411) are used, sound for the slide showing may be stereophonic (see
Fig. 4 "SLIDE + STEREO"). It should be noted that only tape speeds 3%
or 7
slide shows. Before starting to record, write a script detailing the order
in which the slides are to be shown together with the commenting texts
and the background music to be employed. Referring to the script, you
may use the master control (5) , when recording, to fade in and out
the microphone input for the spoken comments and the radio or phono
input for the musical background. To fade over from the microphone
input to the radio or phono input, evenly turn the level of the microphone
input down to zero (the mid-position of the master control) and evenly
increase the level of the music input from zero to the full strength de-
sired. If the spoken commentary is to be accompanied by a soft musical
background, a mixer (like UHER Mix 500 A 124) must be used. Con-
nect the mixer via UHER Stereo Lead K 541 to the RADIO socket of
the SG 631 LOGIC. Read the instruction manual enclosed with the mixer
for instructions on using mixer controls to fade inputs in, out and over.
To check the order of the slide series, slide changing may be manually
signalled while recording. With automatic slide projectors slide changes
may be signalled with the projector's remote control unit, however.
Once the recording of the sound track has been completed, the tape
should be rewound and the slide magazine of the projector returned to
its beginning position for recording the control track.
