Magnetic mixing
(Mixing of sound from additional sources)
1. Switch off erase head (set switch e in Fig. 3 b to
0
).
2. Proceed as when adding new section to an earlier recording.
Transferring optical sound to magnetic track
The universal amplifier permits the transfer of optical sound to a 1.3 mm
magnetic track or a separate magnetic film if the projector is additionally
equipped with a double-system sound attachment. Set function switch h (Fig. 2 a)
for this purpose to OPTICA
L
RE RECORDING (Lichtton-Umspielen). The index of the
head selector a (Fig.?) should come at the bottom
.
The sound lamp is switched
on. The recording may be adjusted with the aid of the optical sound reproduc-
tion control o (Fig. 2 a) and the red button d (Fig. 3 a) with the film running.
Modulation can be checked by observing the magic-fan indicator c (Fig. 3 a).
Sound from one or more additional sources may be added during rerecording
in the manner descr ibed. For reproduction on completion of rerecording, set
function switch h (Fig. 2 a) to MAG
NETI
C REPRODUCE (Magnetton-Wiedergabe)
and turn head selector a (Fig. 7) so that index comes on left.
Servicing the projector
(see instruct ion Manua

for 2000 Projector).
Servicing the sound head
Remove emulsion particles from sound head with a fine-ha ired brush prior
to each performance. Make sure that loop stabi lize
r
and filter roller turn dur ing
film travel.
Servicing the magnetic heads
Particles that have worn off the magnetic layer should be removed from the
magnetic heads at intervals with the aid of a fine-haired brush or hardwood
sliver in order to prevent any reduction in tonal quality.
Do not allow magnetic heads to come into contact with metal (e. g. screw-
drivers) or chemicals (e. g. acetone).
