SAFETY INSTRUCTIONS:
IMPORTANT:
The wires in the mains lead are coloured in accordance with the following code:
If the colours of the wires in the mains lead of this apparatus do not correspond with the colour
markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured green and yellow must be connected to the terminal which is marked by
the letter E, or by the safety earth symbol or coloured green and yellow. The wire which is coloured
blue must be connected to the terminal which is marked with the letter N or coloured black. The
wire which is coloured brown must be connected to the terminal which is marked with the letter L or
coloured red.
GENERAL INSTALLATION
DO NOT run microphone cables near mains, data, telephone or 100V line cables.
DO NOT run 100V line cables near data, telephone or other low voltage cables.
DO NOT exceed 90% of the amplifier’s output power when using 100V line (speech only).
DO NOT exceed 70% of the amplifier’s output power when using 100V line (high level background
music).
DO NOT use horn loudspeakers for background music unless the loudspeaker has been
specifically designed for this purpose.
AVOID jointing the microphone cable, when this is unavoidable make sure a good screened
connector is used, e.g. XLR.
ALWAYS use a balanced or floating low impedance microphone terminating into a balanced input
on long microphone cable runs.
ALWAYS use a mains grade double insulated cable for the loudspeaker cable runs.
ENSURE that all loudspeakers are in-phase.
ENSURE that there are no short circuits on the loudspeaker line before connecting to the amplifier.

3. INSTALLATION
3.1. Cautions
Before you begin, make sure your mixer-amplifier is disconnected from the power source, with the
power switch in the OFF position and all level controls turned completely down (counterclockwise).
Keep enough space among equipments to ensure a correct convection cooling.
3.2. Rack mounting
1. Locate the two rack ears and six rack-ear screws supplied.
2. Place a rack-ear on the right front of the chassis.
3. Insert the screws into the holes of the rack-ear and chassis. Screw them in.
4. Repeat steps 2 to 5 for the left side of the chassis.
5. Remove the four legs from bottom of unit.
Please refer to the following figure.
3.3. Input connections
The following figures show pin assignments for each cable type. RCA input connectors can be
used for unbalanced inputs.

M-120Z
Amplifier
3.4. Speaker lines connection
For the amplifier output connectors is recommended to use high-quality cable. To prevent the
possibility of short-circuits, insulate exposed loudspeaker cable connectors.
The equipment includes 5 terminals for individual 100 V speaker outputs and a terminal for low
output impedance of 4 . The following figure shows speaker output terminals.
AM-120Z Version 1.0 Page 7 of 17

M-120Z
Amplifier
Never use both the Low-Z (8 ) and Hi-Z (100 V) terminals at the same time.
Select the appropriate wire size based on the distance between amplifier and speakers.
3.5. External equipments connection
By connecting a signal processor such as an equalizer or limiter between the mixer section (PRE-
AMP OUT) and the power amplifier section (AMP IN), signals can be tuned for desired sound
output.
Note: Inserting a 1/4-inch phone plug into AMP IN terminal disconnects internal power amplifier
section from the mixer section.
3.6. Expansion
This amplifier allows expansion with LINK IN and LINK OUT connectors. If you need more inputs
and outputs, you can use these connectors to link the amplifier to another unit.

4. FUNCTIONALITY
4.1. Zones selector
This equipment has five buttons for selecting the zones individually and another button for general
call. Music and priority messages will be broadcasted by selected zones.
4.2. Preannounced chime
AM-120Z amplifier incorporates two selectable pre-recorded tones, gong and siren, activated from
the corresponding buttons located on the front panel. Gong activation is activated by pulse, while
siren can be activated by pulse or interlock.
4.3. Input gain control
Channels 1 to 6 have a gain control which permits to adjust, in a 44 dB range, the sensitivity of
each one.
4.4. Priority
This function activates the VOX priority in
channels 1 and 2. The signal of other
channels is muted when this switch is set to
ON and audio signal is detected in the
channel.
This figure shows the position ON and OFF of
priority switch
This equipment has two priority layers:
1 -> Tel-paging, siren, gong and CH1-CH2
(With priority activated).
2 -> CH1 – CH2 (Without priority activated)
and CH3 - CH6.
4.5. Phantom power
This equipment has Phantom power +15
VDC selectable for Channels 1 and 2.
