SECURITY AND THE ENVIRONMENT

ELECTRICAL SECURITY
Check that the current in the mains connection where the machine is to be installed corresponds to the
power supply of the machine.
To avoid damaging the equipment, electrical shocks, fire or physical injury when you connect or disconnect
the equipment from the power supply, pull the plug firmly out of the mains socket holding the plug, never the

cable.
Always do this with dry hands.
Keep the power supply cable far from sources of heat. Do not put heavy objects on top of it or change it.
Clean dust and dirt off the power supply cable regularly.
Do not open the machine; you could get an electric shock.

CAUTION
While installing the machine, make sure it is switched off and unplugged.
Do not open the machine. Touching the internal parts is dangerous and you could receive an electric shock.
The machine must not be splashed or dripped on. Never place recipients with liquid inside on the machine.
Do not place anything inside the machine.

LOCATION
Place the equipment on a horizontal surface with enough space around it to allow ventilation.
Avoid direct sunlight, heat sources and excessive dust.

Do not place the machine near magnetic fields or static electricity.
Do not use surfaces which vibrate or receive impact.
Do not pile machines on top of one another.

VENTILATION
Never block or cover the ventilation slits on the machine.
Do not expose it to direct sunlight or place it near sources of heat.

PERIODS OF INACTIVITY
When the machine is not going to be used for a long period of time, disconnect it from the mains.
If you are using an adapter, take into account that it will continue using electricity even if the machine is
switched off. If it is not going to be used for a long period of time, disconnect it from the mains.

THE ENVIRONMENT
To save energy, switch the machine off when you are not going to use it for a long time. The machine could
contain substances that are harmful to the environment or human health. To minimize the effect of these
substances the machine must be correctly managed and recycled when you decide to dispose of it.
When you dispose of it remember: it cannot be thrown into a conventional rubbish bin.
If it contains or uses batteries, these must be disposed of separately.
The machine (without batteries) must be disposed of correctly. Put it in a container specially intended for the
collection of electronic and electrical appliances, at the dump or hand it over to the dealer when you purchase

similar equipment, so that the dealer can dispose of it correctly (at no added cost).

DESCRIPTION

- 2-channel power amp.

- 2 x 500 W RMS. Loudspeaker output 4 and 8 Ω, 100 and 70 V lines.

CONTROLS AND FUNCTIONS

FRONT PANEL

1.- CH 1/CH 2: volume control wheels for channels 1 and 2. It is recommended that you do not raise these
volume controls to their maximum. Position them at 3/4 for optimum results.

2.- PROT: LED protection indicators. They light up when protection is activated due to a surge or short­circuit. With protection activated the audio output is cut off.

3.- TEMP: LED temperature protection indicators. They light up when protection is activated due to excess
temperature inside the equipment. With protection activated the audio output is cut off.

4.- CLIP: LED peak signal indicators. They light up when an input signal is detected with a level that is too
high in the corresponding channel or when there is an excess output level that could damage the
equipment.

5.- SIGNAL: LED indicators that light up when an input signal is detected in channels 1 and 2.

6.- Power amplifier on/off switch.

7.- ON: LED power indicator for the power amplifier.

BACK PANEL

1.- LINK: balanced signal output for channels 1 and 2 for connecting several pieces of equipment in
cascade. XLR connector.

2.- INPUT: balanced signal input for channels 1 and 2, XLR connector.

3.- GND LIFT: this selector is normally in the GND position. If the installation has mass noises, move the
selector to the LIFT position to disconnect the mass and the earth from the equipment.

.- Operating mode selector.

5. Power supply input 230/115 V AC.

6.- BREAKER: resettable fuse, 10 A. When the power amp is overloaded or there is a surge, the fuse will
be cut off to avoid damage. It is reset by pressing it.

7.- Power supply voltage selector.

8.- GND: earth connection terminal.

9.- OUTPUTS: loudspeaker output terminals. Use just one output depending on the charge impedance: 4
or 8 Ω low impedance lines or 70 or 100 V high impedance lines. Connect the loudspeakers between
the COM terminal and one of the output terminals: 4 Ω, 8 Ω, 70 V or 100 V.

CONNECTION

- Before making any connections make sure that all the equipment has been switched off.

- Check the the CH 1 and CH 2 volume controls are at their minimum.

Depending on the desired application, 3 operating modes can be selected using the switch on the back of
the equipment: parallel mode (PARALLEL), stereo mode (STEREO) and bridge mode (BRIDGED).

PARALLEL MODE (PARALLEL)

Move the switch on the back of the power amp to the PARALLEL position.
In this mode, the input for the 2 channels will be the CH 1 channel input signal. Connect the CH 1 channel

input and the 2 loudspeaker outputs. The output volume in the 2 channel is adjusted separately.

STEREO MODE (STEREO)

Move the switch on the back of the power amp to the STEREO position.

In this mode, the 2 channels will work independently. Connect the 2 inputs and the 2 speaker outputs. The

volume of the channels is adjusted separately.

BRIDGE MODE (BRIDGED)

Move the switch on the back of the power amplifier to the BRIDGED position.

In this mode, lthe input for the 2 channels will be the CH 1 channel input signal. The 2 channels in the power
amplifier are connected internally so that their power is joined in just one output. Connect the input from CH
1 channel and the BRIDGED speaker output. The volume is adjusted with the CH 1 control.

INSTRUCTIONS FOR USE

ON AND OFF

Before switching the power amp on check that the volume controls for channels 1 and 2 are at their minimum.
Switch on the rest of the audio system and lastly, switch on the power amp and adjust the volume in the
channels.

To switch the audio system off, adjust the power amp volume to its minimum and switch it off. Lastly, switch
off the rest of the audio system.

PROTECTION

The power amplifier has 4 types of protection: overload, overcurrent, surge and temperature.
When protection is activated, an LED indicator will light up on the front panel and the audio output will be

cut off. If this happens, switch the power amp off, check what has caused the protection to be activated, leave
it to recover for a while and switch it on again.

RESETTABLE FUSE

The power supply source has been manufactured using advanced components that absorb current peaks
and eliminate fluctuations caused by turning the the amplifier on. Furthermore, it is equipped with a 10 A
BREAKER resettable fuse on the back panel.

If the fuse is cut off, due to a surge or excessive consumption, switch the power amp off, check what has
caused the fuse to be cut off, let it recover for a while and reset the BREAKER fuse by pressing it.
