3.7. Output connections
The output section on the rear panel holds 12 screw-type speaker terminals (33, 34, 35,
36, 37, 38), two for each amplifier.
The attenuation controls and the output configurations are described later in paragraph
6.3.
The cable which connects the speakers to the amplifier should be high quality and as short
and thick as possible. This is important when covering long distances; For up to 10m we recommend
a cable section not smaller than 2.5mm². For longer distances we recommend 4mm².
Remember that the minimum load impedance for stereo or mono amplifiers is 4
Ω
. In
bridged mode the impedance must be not less than 8
Ω
. For a reliable operation under any
circumstance connect lower load impedances than just specified.
Attention: In bridged mode, use only the red terminals.
4. OPERATION AND USAGE
4.1. Start up
To switch the unit on just push the switch labelled POWER (20) and the integrated
pilot-light will light up. We highly recommend the "safe power-up sequence": First the sound sources,
then mixer, equalizers and active filters and, finally, power amplifiers. Powering off should be done
by following the exact reverse sequence in order to avoid any possible peaks reaching the next
device, and consequently protecting the loudspeakers, which are specially sensitive to these peaks.
