NOTES 52 INTRODUCTION Thank you for your purchase of the ORION DEQ 30. The latest technological advancement in car audio signal processing, the DEQ 30 is the worlds first stand alone digital 30 band 2 channel equalizer. The DEQ 30 processes all the equalization in the digital domain and comes equipped with both analog to digital and digital to analog converters. The DEQ 30 contains four preset stations called “zones” which allow storage of several equalization curves. This is especially useful

TECHNICAL OVERVIEW TRUE DIGITAL EQUALIZATION: All equalization is performed digitally by proprietary digital algorithms. Digital equalization achieves perfect phase response. The signal-to-noise ratio is unaffected by equalization adjustments. Frequency centers, boost levels and “Q” values are exact. There is no variance like analog circuits. Additionally, digital equalization eliminates oscillations normally associated with analog circuits. 30 BANDS SEPARATE LEFT AND RIGHT ADJUSTMENT: 30 band
