3 INSTALLATION

3.4 Cooling

Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and out through the back. It is of course essential that while the power amp is running air is able to circulate around it freely.

The efficiency of the cooling will depend on the immediate environment (e. g. an enclosed rack, direct sunlight) and on whether the front filter is clogged. If the amp is installed in a case the open area at the back of the case must be at least 140 cm². This area should be in line with the amp.

If this can not be achived a forced ventilation system has to be used.

3.5 Wiring

3.5.1 Input Connectors

XLR:

Pin 1 = Ground

 

Pin 2 = Hot (inphase, +)

 

Pin 3

= Cold (out of phase, -)

Euroblock connector:

Pin 1

= Hot (inphase, +)

 

Pin 2

= Ground

 

Pin 3

= Cold (out of phase, -)

Make sure to always use high-quality symmetrical (balanced) shielded cable to ensure maximum audio quality.

Please do not simultaneously attach two independent signal sources to the XLR and Euroblock input connectors of the same channel.This could lead to volume and audio quality loss and could damage the connected signal sources.
