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, 16Ωdepending 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, 16Ωis 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.
