Power Monitor 8 (discontinued)
A new power test solution (hardware and software) is currently under development and scheduled for release in 2021.
Please contact support(at)klippel(dot)de for details.
- Special hardware for power testing
- Eight channel speaker monitoring
- Voltage (< 240 V)
- Current sensor (< 50 A) without additional serial resistor
- Stand-alone and PC-controlled operation
- Fast, hot plug USB interface
- Large internal memory for long term tests
- 19” / 2U rack mountable
Power Monitor 8 is a special hardware platform for the long term testing of up to 8 speakers simultaneously. The hardware hosts a high performance digital signal processor for demanding calculations and accurate 24 Bit AD/DA converters with a sampling frequency up to 96 kHz1. The Power Monitor 8 can be operated as a stand-alone unit by using the key pad and the display. Connecting a computer via USB-interface the computer software dB-Lab and several measurement modules can be used to control the unit and visualize the results. In addition to the 8 channel speaker monitoring the hardware provides a two channel line (XLR) in- and output.
[1] The maximum usable sampling frequency depends on the used software.
