3.8. Output connections

The OUTPUTS section at the rear panel has screwable terminals (33, 34, 35, 36), one for each
amplifier.
The attenuation controls and the output configurations are described later in paragraph 3.9.
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 4Ω. In bridged
mode the impedance must be not less than 8Ω. For a reliable operation under any circumstance connect
lower load impedances than just specified.
Attention: use only the indicated terminals when using the amplifiers in bridge mode.
