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.
