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.
