2-Channel Front End
BEQ II.1
*Binaural, digital equalizer with 24 bit technology and USB interface.*The digital equalizer BEQ II.1 combines the characteristics of an equalizer, a two-channel front end and an A/D converter into one mobile and very versatile measurement tool.*Binaural, aurally-accurate recordings can be conducted easily with BEQ II. The AES/EBU interface allows a quick and easy expansion into a four-channel system, e.g. with the HMS III or HMS IV. Via the ADAT interface, up to four BEQ II units can be connected, allowing for eight-channel recordings.*Integrated signal conditioning allows common measurement sensors (Microphone, Line, ICP�) to be directly connected to the front end. In addition, separate pulse inputs are available e.g. for RPM data acquisition.*Thanks to the high-performance built-in battery - external DC power supply is also possible - and its low weight, BEQ II.1 is the ideal tool for either mobile or stationary operation.

Artificial Head & Binaural Recording
With binaural recording systems, you can record sounds true to reality, as if you were in the sound field yourself. Our variety of artificial heads accurately reproduce all acoustically relevant components. Ear simulators with different microphones enable aurally accurate recordings, while mouth simulators allow speech playback in the transmitting direction when voice and audio quality are tested in the laboratory.
