POWER SUPPLY
Ensure that the insource voltage (AC outlet) matches the voltage rating of the product. Failure to do so could result in
damage to the product and possibly the user. Unplug the product before electrical storms occur and when unused for
long periods of time to reduce the risk of electric shock or fire.
EXTERNAL CONNECTION
Always use proper ready-made insulated mains cabling (power cord). Failure to do so could result in shock/death or
fire. If in doubt, seek advice from a registered electrician.
FUSE
To prevent fire and damage to the product, use only the recommended fuse type as indicated in this manual. Do not
short-circuit the fuse holder. Before replacing the fuse, make sure that the product is OFF and disconnected from the
AC outlet.
PROTECTIVE GROUND
Before turning the unit on, make sure that it is connected to Ground. This is to prevent the risk of electric shock.
Never cut internal or external Ground wires. Like wise, never remove Ground wiring from the Protective Ground
Terminal.
OPERATING SAFETY INSTRUCTIONS

This symbol, wherever used, alerts you to important operating and maintenance instructions.
DO NOT REMOVE ANY COVERS
Within the product are areas where high voltages may present. To reduce the risk of electric shock do not remove
any covers unless the AC mains power cord is removed. Covers should be removed by qualified service personnel
only. No user serviceable parts inside.
POWER CORD AND PLUG
Do not tamper with the power cord or plug. These are designed for your safety. Do not remove Ground connections!
If the plug does not fit your AC outlet seek advice from a qualified electrician. Protect the power cord and plug from

n t r odu c t i on
Thanks for the acquisition of the PX-360 AUDIOPOLE. This professional power amplifier was
developed for fixed installations requiring limited space in the bays.
The PX-360 has a high efficiency thanks to his Class-D technology and can deliver 2x180 WRMS
on 4 Ohms. It also works securely with 2 Ohms loads. A Bridge mode enables to power a mono
device like a subwoofer or a low impedance loudspeakers line.

5– PROT
Protection indicator. If the amplifier fails, the Led lights up, the output being automatically muted. Check
the cable connection between the amplifier and the speaker. Also check that the vent grille is not
obstructed. If the amplifier is installed into a bay, there is a risk that the cooling is not sufficient and the
temperature can raise to the upper limit level where the protect mode is triggered.
6 – C L IP
Clipping indicator. The Led lights up as soon as the distortion rate exceeds 0.5%. The input level is too
high and it is necessary to decrease the volume or to switch the limiter on.

• B r i dg e Mode
!
In Bridge Mono mode the power capacities of the two channels are cumulated to be used with one
single load.
The input signal must be connected to channel 1 of the amplifier. Channel 2 is not used and its volume
control must be set to zero.
Warning, the following connection rules must be respected:
• the positive terminal (+) of output 1 must be connected to the positive terminal (+) of the
speaker.
• the positive terminal (+) of output 2 must be connected to the negative terminal (-) of the
speaker.
