amplifier selected. Possible you have to schedule this test after working hours, when
less/no people are in the test environment.
– As soon the Start button is clicked, the system generates an audio signal to measure
the load connected to each amplifier output channel.
2. Click Channels (below Topology) as soon the measurement has been finished:
– Only the overload power (in Watt) connected to the A and/or B output is indicated in
the Overload column. See Amplifier, page 48 .

Caution!
When a load measurement is done with one of the loudspeaker lines shorted, the webpage
will indicate; “not measured”. Resolve the short and start the load measurement again to
resolve this.
