Page 3: Safety Instructions
Important Safety Instructions This symbol, wherever used, alerts you to the presence of un-insulated and dangerous voltages within the product enclosure. These are voltages that may be sufficient to constitute the risk of electric shock or death. This symbol, wherever used, alerts you to important operating and maintenance instructions. POWER SUPPLY Ensure that the insource voltage (AC outlet) matches the voltage rating of the product. -
Page 4: Introduction
3.7 kg in one unit rack. PX 500 offers 3 different modes. STEREO mode is a stereo amplification who can provide 2 x 180 W / 8 Ohms or 2 x 250 W / 4 Ohms. BRIDGE mode provides 500 W / 8 Ohms. PARALLEL mode amplifies a mono source, using resources from 2 channels. -

Page 7: Operating Modes
Operating Modes STEREO Mode This is the standard mode: both channels functioning independently, the attenuators (2) and (3) respectively controlling each channel input levels. The recommended nominal load impedance is 8 or 4 Ohms per channel. The speakers are connected to the terminals as shown in the figure below. BRIDGE Mode It is a monophonic mode, both channels work with the same signal input, but in phase opposition. -
Page 8: Installations Hints
Operating Modes PARALLEL Mode In this mode both channels of the amplifier receive the same signal connected to the input 1, both attenuators (2) and (3) remaining active. The speaker outputs wiring is identical to Stereo mode. Installations Hints In case of installation in cabinet or rack, ensure the ventilation requirements. The depth of the device is 277 mm, the height is 1 unit rack (44 mm). -
Page 9: Connectors
Connectors PX 500 input connectors are balanced (XLR) and unbalanced (RCA). Cables related to connecting to other equipment must therefore be of the same nature. Are listed below types of different cords with their electrical connection diagram. Balanced Unbalanced Impedance load When connecting multiple speakers or speakers on the same channel, various types of connection are possible. -
