SA-132 Instruction Manual – Guide d'utilisation
Equalizer Controls
Three different controls for three frequency bands. Those volume controls will increase or decrease bass and
treble or add some presence to the sound.
Manual Priority Terminals
These two terminals, when shorted, will mute incoming signal from AUX and CD inputs, thus giving priority to
the Telephone Paging and Microphone. These are especially useful when a table microphone with switch is part
of the installation.
Speaker Terminals
These terminals are offering 3 low voltage outputs 4Ω, 8Ω, 16Ω depending on your speaker combination. A
70V/100V commercial output is also available. Please note that one wire only should be connected to COM
screw and one wire to the selected impedance or voltage. Multiple combinations cannot be done at the output
level.
Four different types of connections are provided. The low
impedance section: 4Ω, 8Ω, 16Ω is designed for a small amount
of speakers to be connected to your amplifier. The 70V section
is especially designed for a multiple speaker distribution. When
using the 70V output, speakers have to be equipped with 70V
transformer. The maximum amount of speakers to be placed
on your distribution line is in relation to the power allocated to
each speaker. The total wattage set on the secondary side of
the transformers on your speaker line must not exceed the
maximum RMS output power: 30W or 60W. Failure to respect
this may cause permanent damage to the amplifier.
Microphone Input
This ¼" jack is a two conductor unbalanced microphone input. If you wish to use a low impedance microphone
on a balanced line with a long cable, we recommend that you use an AM-15 adaptor to do so. If you choose to
use a Table Top microphone with an enunciator switch, keep in mind that the switch should be connected to the
two priority terminals.
Music on Hold
This output will feed music on your telephone system for people waiting to be answered. A dedicated input
should be available on your telephone system. Please refer to a qualified technician if you can't identify this
input. Outgoing signal should be connected to G and H. Volume control is located next to the terminal in order
to provided proper level of music on the phone system.
