The digital audio matrix boards PC1001-A3 and PC1002-A3 feature audio paths with:
- 4x independent digital audio channels with:
- 4x analog audio inputs
- Digital audio input with up to 255 channels
- Digital audio matrix
- 1x 100 V speaker line output matrix to 16 speaker line outputs with:
- 4x amplifier inputs
- 1x backup amplifier input
- 1x pilot tone amplifier input
- amplifier supervision
- speaker line detection
The output of an audio amplifier PV100x-A1 is connected to the 100 V audio inputs of the PC100x.
The speaker lines are connected to the 100 V speaker line outputs.
NOTICE
PV1001-A1 supports maximal 2 A output current in a minimal 50 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 140 W per amplifier.
In a 50 V speaker system, the max speaker load is 100 W per amplifier.
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.
