Power Monitor 8 (PM 8)

Power Monitor 8 is a special hardware platform for the simultaneous long-term testing of up to 8 speakers. The hardware hosts a high performance digital signal processor for demanding calculations and accurate 24 Bit AD/DA converters with a sampling frequency of up to 96 kHz. The Power Monitor 8 can be operated as a stand-alone unit by using the key pad and the display. Connecting a computer via the USB interface, the computer software dB-Lab and several measurement modules can be used to control the unit and to visualize the results. In addition to the 8 channel speaker monitoring, the hardware provides a two channel line (XLR) in- and output.
