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 ROBO3 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.
