The amplifier features a transistorized circuit, which automatically mutes the other inputs and allows
microphone #1 to talk 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.
4 , 8 , 16 Connection
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 possible; use a suitable cable diameter.

1) Each speaker must be equipped with a line transformer with an input voltage equal of the line voltage
used.
2) The sum of the power capacities of the speakers must not exceed the output power capacity of the
amplifier.
3) The length of the connecting cables must be short as possible; use a suitable cable diameter.
