1) Calculation of the maximum audio payload at 100 V (Sinus)3):
- The maximum audio payload per amplifier channel depends on how many loop isolators (100 V) are connected.
'Audio payload' [W] = 'power of the amplifier channel' – ('number of loop isolators' * 0.5 W) |
2) Twisted cable types are not permitted.
3) Amplifier plays a continuous sinus signal with an output voltage level of 100 V: the 100 V is pilot tone signal plus input sinus signal
4) Loop audio matrix = PC1001-A3, PC1002-A3, PC2003-A1
* Tapping: 100 V speakers have a transformer upstream of the chassis. The transformer has several taps on the primary side, which is where the 100 V speaker line is connected. These taps determine how much power is drawn by the speaker. With a 100 V signal, ceiling speakers typically taps to draw a power of 6 W, 3 W, 1.5 W, or 0.75 W. Halving the electrical power leads to a 3 dB reduction in the analog audio output signal.
