PRIORITY PAGING:
The amplifier features a transistorized circuit which automa-
tically removes all program material for the amplifier and
permits microphone #1 to take over for special or emergency
announcements.
This electronic switch is operated from the microphone, which
must contain a single-pole switch, normally open for actuating
this circuit.
A turntable with a high impedance ceramic or crystal cartridge
may be connected to an AUX. input.
The external " ACOUSTIC EQUALIZER " is connected to the
SEND and RECV receptacles on the rear panel of the amplifier,
SEND is connected to the input of the external "equalizer" and
RECV to the output of the external.
3. Output connections.
Caution.
¡ To avoid the risk of electrical shock, never touch the bare
conductors leading to the output terminals of the amplifier
when it is in operation. Show the possible connections of the
"output" speaker terminal accessible by removing the protective
cover. Bear in mind the following rules:(see following).
¡ Re-apply the output terminal cover and fasten the screws after
¡
Constant the low impedance lines.
(1) The total impedance of the speakers connected must
correspond to that selected on the amplifier's output terminals.
(2) The sum of the power capacities of the speakers must be
no lower than the amplifier's power capacity.
(3) The length of the connecting cables must be short as poss-
ible; with equal of line that CLASS ¢ wire .
¡Constant the high voltage lines.
(1) Each speaker must be equipped with a line transformer
that with an input voltage, with equal of the line that CLASS
¢wire .
