Contact with live parts can lead to electric shock and may be fatal!
- Disconnect AC 230 V mains voltage before installation or maintenance.
- Disconnect DC 24 V power supply voltage before installation or maintenance.
- Ensure that the power supply cannot be re-energized inadvertently.
Using a 70 V speaker system by reducing the input level by -3 dB leads to a max output voltage of 70 V. This results in a max speaker load of 350 W per amplifier.
In 50 V speaker system, the max speaker load is 250 W per amplifier.
The speaker lines are connected to the speaker line output connectors X101-1 and X101-2.
The speaker lines can be configured in stub or in loop configuration.
In stub configuration the speaker lines can be supervised with PCA2004-A1 EOL3 (active) or with impedance supervision.
In loop configuration the speaker lines are supervised with PCA2005-A1 Loop isolator (100V).
It is not allowed to connect speaker lines with PCA2004-A1 EOL3 (active) and PCA2005-A1 Loop isolator (100V) on one Cerberus PACE system.
