OVERVIEW 1 . 2 F E A T U R E S The following is a summary of your DEQ 624’ s features: 24-Bit Digital Signal Processing. The DEQ 624 utilizes 24-Bit resolution for accurate processing of analog signals. Dual 31 Band Equalizers. Each channel of the Graphic Equalizer section of the DEQ 624 is comprised of 31 digital EQ encoders. - Page 9 Entering a user-created three-switch code combination restores complete operation of the unit’ s front panel controls. AHC-Adaptive Hum Cancellation. This is a proprietary feature of the PreSonus DEQ 624. Annoying 50 Hz /60 Hz system hum caused by grounding problems can be greatly reduced without effecting program content by simply by engaging AHC.

CONTROLS & CONNECTIO NS Gain Reduction Meter The Gain Reduction Meters of the DEQ 624 monitor the activity of both the Expander and Limiter. These 10 segment LED meters are calibrated in increments from dB to dB and show the amount of Gain Reduction applied by the dynamics processors. The Gain Reduction meter continues measuring processor activity in Bypass mode. -

CONTROLS & CONNECTIO NS selecting 20 kHz allows all frequencies from 20 kHz and below to pass through unaffected, effectively turning the Low Pass filter “Off”. Expander The DEQ 624 Expander is provided to eliminate system noise. The Expander is controlled by selecting a threshold point for downward expansion to begin and by selecting a ratio, which controls the amount of downward expansion. -
