The DC-One provides a stereo nine-band multi-mode filter generically referred to as the Input PEQ (Parametric Equalizer). The Input PEQ is a very powerful and complex set of multi-mode filters. Care must be given configuring these filter bands, as they interact and can produce unexpected results. Using the DC-One Editor PC application is strongly recommended to set all but the most simple eq curves.

Each band of the Input PEQ can be configured for a specific filter mode, frequency, slope or Q and gain setting. Attention must be paid to the ultimate output gain through the rest of the DC-One’s audio path, as it is possible to boost frequency ranges to the point where the internal or external audio paths of the system may be clipped. Monitoring the output VU meters of the DC-One’s output channels will indicate internal clipping; the input meters of connected amplifiers should do the same.

To bypass any band of the DC-One’s Input PEQ multi-mode filter bank, set the desired band’s gain to 0.0dB. This will have

the effect of bypassing the selected filter band.

The following section details the type of filters that can be selected for each of the Input PEQ’s 9 bands and their parameters:

Low-shelf

The Low-shelf filter is a “hinge” type; in that frequencies below its frequency setting can be boosted or cut; hinging on the cut-off

Frequency. The amount of boost or cut (Gain), and the extent of width of the filter’s transition band (Slope), are determined by the low-shelf filter’s settings. (See Response/Q and Gain.)

Use the < Select > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap around.)

Hi-shelf

The Hi-shelf filter is a “hinge” type; in that frequencies above its frequency setting can be boosted or cut; hinging on the cut-off Frequency.

The amount of boost or cut (Gain), and the width of the filter’s transition band (Slope), are determined by the hi-shelf filter’s settings. (See Response/Q and Gain.)
