Parallel-bridge mode cabling

This mode combines four amplifier channels into one drive channel. Speaker gets connected

to 1+ and 3+ (resp. 5+ and 7+) with a connection between 1+ and 2+, as well 3+ and 4+ (5+

and 6+, 7+ and 8+), see illustration.

6.5 Audio inputs

Audio input connectors on IPX series are Euroblock type for 4 channels (IPX5:4, IPX10:4,

IPX20:4) respectively 8 channels (IPX10:8). This allows an easy pre-wiring of the cables

outside the rack and a fast single connector for connecting multiple channels at once, without

the danger of wiring errors.

The pin out is labeled on the rear of the amplifier. It is highly recommended to use a balanced

input cabling whenever possible.

In addition to the analogue inputs IPX amplifiers can also receive their input signals from an

OMNEO or a Dante network. Input source can be changed via the front panel or using remote

control software.

6.6 Fan cooling

The power amplifier has four fans. The fans are fully controlled and supervised by the

amplifiers management system and adjust their speed depending on the temperature. The

temperatures of the power amplifier’s channels are registered and monitored individually.
