WARNING
Voltages of up to AC 100 V at the speaker line jumpers

Contact with live parts can lead to electric shock and may be fatal!

  1. Disconnect AC 230 V mains voltage before installation or maintenance.
  1. Disconnect DC 24 V power supply voltage before installation or maintenance.
  1. Ensure that the power supply cannot be re-energized inadvertently.
NOTICE
PV1002-A1 supports maximal 5 A output current in a minimal 20 Ω speaker load resistance.

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.
