The EAR825 is a stereo equalizer for studio use where sound quality is the top priority. Housed in a single 3U 19-inch rack mount unit, it gives the user flexible and intuitive control over a wide range of response shaping options On each channel there are five bands of EQ. Shelf filters give boost or cut in the bass and treble. with four corner frequencies on each control and variable degrees of boost or cut. In addition there are three tuned boost/cut filters with center frequency adjustable over a total range of 60Hz to 16kHz. These give a maximum boost or cut of 12dB, allowing quite large response variation but without sacrificing sensitivity. Controls are laid out for maximum ease of use and can be bypassed at the flick of a switch for quick reference to the original signal.
