The CE22 is a professional multi-band enhancer/exciter designed for various applications. This unit combines 2 processors to align the phase and focus of bass frequencies, improve the response of mid-high frequencies and add harmonic content to any "dull" sounding audio. The surround processor utilises the phase alignment engine to give a greater perceived width to the stereo field.Power supply: 115/230Vac, 50/60Hz (IEC)vbCrLfFrequency response: 20Hz-20kHz (+0/-3dB)vbCrLfInput impedance: 12k OhmsvbCrLfOutput impedance: 45 OhmsvbCrLfTHD: 0.008% @ +4dBu 1kHzvbCrLfSignal to noise ratio: >95dBuvbCrLfDimensions: 482 x 44 x 250mmvbCrLfWeight: 3.5kg
