Measurement System Monkey Forest

Monkey Forest is an all-purpose DOS-based measurement system for audio and acoustics. Together with an RME Multiface II or a Digiface, measurements of all kinds of electric gear like amplifiers, controllers, etc. can be carried out.

Our frontend Robo provides microphone preamps and power amps to carry out 2-channel room-acoustic or loudspeaker measurements. Input and output gains as well as different modes for calibration, reference and impedance measurements can be remote controlled by the software.

Components of the measurement system mounted into a mobile 19” 3U case. I/O connectors from the Multiface’s rear panel are accessible at the front panel. Only the power plug and the firewire cable need to be connected.
