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 bands of equalization set to the exact frequencies on 1/3 Real Time Analyzers. Left and right channels can be adjusted individually.

4 PRESET WORKING ZONES:

4 working zones create different preset response curves for every listening preference.

ANALOG INPUT SECTION:

THE DEQ 30 uses an 18 bit balanced delta sigma analog-to-digital converter with 128 times oversampling. It accepts both RCA and Balanced (Mini XLR™) inputs. Left and right input sensitivity adjustments are fully variable and independent.

DIGITAL INPUT SECTION:

The digital input section uses a Professional Grade SPDIF receiver. It uses the same receivers used in high-end home audio and professional applications. The DEQ 30 supports 44.1 kHz and 48 kHz sampling frequencies and both TOSLINK and COAX digital inputs.
