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 r erecording, set
function switch h (Fig. 2 a) to
MAGNE TI C REPRODUCE (Magnetton-Wiedergabe)
and turn head selector a (Fig. 7) so that index comes on left.
Servicing the projector
(see instruction Manua l for 2000 Projector).
Servicing the sound head
Remove emulsion particles from sound head with a fine-haired brush prior
to each performance. Make sure that loop stabilizer and filter roller turn dur i ng
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).
