1. INTRODUCTION.

The UP-120M4 model is made up of 4 amplifiers of 120 Watts R.M.S. each, housed in the same

frame.

Suitable for use in public address installations, emergency paging, background music and

speech reproduction systems. Their toughness and reliability must be outlined as well.

Each amplifier includes a protection against short-circuits / over-loadings in the loudspeakers

line, as well as a thermal protection to avoid damages due to over-heating.

They occupy 3U when mounted in a 19” Standard Rack Cabinet. When Rack mounted, it is

recommended to install 1U perforated panels between them.

2. FRONT VIEW.

(1) LEVEL INDICATORS.

To indicate the power delivered to the line.

The LED marked as 0 dB indicated the

maximum power given by the amplifier.

(2) PRIORITY INDICATORS.

They light when the Priority channel is

selected, it is: when the pin n. 6 is joined

to the pin n. 8 in the RJ45 connector of the

Priority Input.

(3) PROTECTION INDICATORS.

They light when the Protection is operating

due either to an over-loading or to a short-circuit in the loudspeakers line.

(4) VENTILATION INPUT.

Do not obstruct under no circumstances.

(5) PRIORITY INPUTS VOLUME CONTROLS.

Turn them clockwise to increase the volume of the Priority channels. The potentiometers can be

adjusted by using a screwdriver.

(6) PROGRAM INPUTS VOLUME CONTROLS.

Turn them clockwise to increase the volume of the Program channel. The potentiometers can

be adjusted by using a screwdriver.

(7) ON/OFF LED INDICATOR.

It lights when the amplifier is in operation, either by Battery or Mains.

(8) ON/OFF SWITCH.

It switches on/off the amplifier only if the power is supplied by the 230 Vac mains. This switch is

not operational when the amplifier is supplied by battery.

3. REAR VIEW.

(1) SECURITY PAGING AUXILIARY RELAYS.

They are switched when the corresponding priority contacts

of the PRIORITY channels are activated.

(2) LOUDSPEAKERS LINE OUTPUTS.

The Loudspeakers line outputs are done by means of transformers with low impedance outputs

(8 Ohms) and high impedance outputs (70-100 V).

The connection is made between the

"0" (common) terminal and the one

corresponding to the chosen

impedance or voltage.

(3) CONNECTION TO THE 230 V.a.c.

MAINS.

The rear panel has a male base for

the CEE22 supply which allows its

connection to the mains by means of

the cable included.

(4) MAINS FUSE.

It is located into the lower box of the power supply base. In the same box there is a replacement

fuse as well.

(5) BATTERY SUPPLY INPUT.

This supply allows the use of these amplifiers in security installations, connecting the same to a

24 V.d.c. battery.

The ON/OFF switch doesn't cut the supply from the battery.

(6) CONNECTION OF THE GROUND TO THE FRAME.

In all P.A. installations, it is very important to have only a joining point between the signal

ground and the mains ground contact.

If the P.A. installation is made up of several equipments, they will probably have the frames

joined either by means of the ground terminal of the mains connection, or because they are

mounted in a rack cabinet.

If the grounds are also joined

by the signal circuits, it is

advisable to remove the

jumper between the ground

and the frame of all

equipments excepting one.

Attention: this equipment

cannot be splashed or

exposed to water.

(7) VENTILATION OUTPUT.

Do not obstruct this output under no circumstances.

There is a fan in the rear panel, always in operation, changing its speed depending on the

temperature reached in the equipment.

(8) ADJUSTMENT OF OPTIONAL OSCILLATORS.

If OSC-02 (optional circuits needed for the lines supervision) are installed into the UP120M4,

these controls allow adjusting the oscillation signal level.

To do the adjustment, follow the steps indicated in the manual of the DALA-01/DA card. The

adjustment must be done with the corresponding loudspeakers line loaded.

Place the oscillators circuits. Follow the steps shown in the figure 4

(9) PRIORITY CONTROL TERMINAL BLOCK

These contacts allow the activation of the amplifier priority, facilitating the installation wiring.

The block diagram shows an example of installation with four zones. Each zone is connected to

one section with different functions; (See figure 5).

SECTION 1. The zones selector activates the priority (zone 1). The audio signal is given by

micro 1.

SECTION 2. The zones selector activates the priority (zone 2). The audio signal comes from

microphone 1 trough the priority out of section 3.

SECTION 3. The priority contact and audio signal are directly connected to microphone 2.

SECTION 4. The priority contact is activated by the zones selector (zone 4). The audio signal

comes from micro 2 from the priority output of the section 3.

(10) PRIORITY CHANNELS & (11) PROGRAM

CHANNELS.

The two input channels (PROGRAM & PRIORITY) from

each amplifier use 4 RJ45 type connectors in parallel 2

to 2.

This way, they can provide signal to other power units

(see figure 6).

For the connection, you must use STP Cat 5 cable,

which main feature is that it has a very low impedance,

which allows to have an exceptionally flat frequency

response even for long distances, and to comply with the

CMRR & Crosstalk features required for the analogical

audio systems.

The signal inputs are balanced by transformer and have a sensitivity of 0 dBu (775mV). The

pin n.º 3 provides a 24 Vdc voltage which can be used to supply devices of low consumption.

The maximum intensity supplied is of 200 mA in each channel.

In the PRIORITY channel, when joining the pin º 6 to the pin nº 8, the priority system is

activated as well as the security paging auxiliary relay. It is possible to transmit the priority

control to other power units through the pin nº 6 of the PRIORITY OUTPUT connector, always

depending on the position of the dipswitches 7 & 8 (see section 3. REAR VIEW, nº 9).

12) DIPSWITCH.

SHIELD - GND LINK. (dipswitches nº 1, 2, 3

& 4).

These 4 dipswitches allow removing the cable

shielding from the internal ground of the

equipment for each one of the RJ-45

connectors. Normally they are in ON position

(shielding and ground joined). To separate the

same, place the corresponding dipswitch in

OFF position.

PRI-PRO LINK (dipswitches nº 5 & 6).

These two dipswitches join internally the H audio signal and the C audio signal (when the input

is balanced) that are in the PRIORITY OUTPUT with the PROGRAM INPUT. Normally they are

in OFF position (separated audio signals). To join the same, place the corresponding dipswitch

in ON position.

PRIORITY CONTROL IN (dipswitch nº 7).

In OFF position, it disables the priority contact

of the RJ PRIORITY INPUT connector.

PRIORITY CONTROL OUT (dipswitch nº 8).

In OFF position, it disables the priority contact

of the RJ PRIORITY OUTPUT connector.

JPA (dipswitch nº 9).

Put OFF when the equipment includes the

oscillators.
