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.
