  • Page 9: Configuration

    8. Configuration 8. Configuration 8.1 Balanced and unbalanced Inputs The amplifier can accept unbalanced and balanced lines. For optimal performance and with longer cable runs, use balanced lines whenever possible. The driving device should be equipped with a balanced output. With short cables inside one rack the issue is not that critical. A balanced connection provides excellent noise immunity from interference and ground loops.

  • Page 10: Grounding

    8. Configuration 8.4 Grounding The chassis of the amplifier is connected with the ground of the AC power cord. As soon as several devices are connected with each other in a signal chain, a ground loop is created. Ground loops are caused when current flows from the analog ground plane of one device to the ground plane of another device.

  • Page 11: Amplifier Standby Input & Link

    8. Configuration PA 8125 examples: NOTE: make sure that the total connected load at 50 V/100 V and total power for low impedance loads never exceed the total of 1000 W and that the maximum power capability for a single channel is not exceeded.

  • Page 12: Vdc Input

    9. Technical Specifications 8.10 48 Vdc input The 48 Vdc input can be used for emergency power backup sources such as batteries. When the 230 Vac mains power source is disconnected or fails the internal power supply automatically switches over to the 48 Vdc input. When operating from a 48 Vdc power source the amplifiers rated output power specifications will not be affected, until the battery voltage starts to reduce below its minimum voltage.

  • Page 15: Appendix A

    Appendix A Appendix A Connecting 100 V loudspeakers on lines with different voltages: Connecting a 100 V loudspeaker on a 50 V amplifier output will not cause any problems; this does however result in a loss of sound pressure level. The use of 100 V loudspeakers on amplifier outputs with higher voltages (>100 V) needs to be avoided as this might damage the loudspeaker.
