Chapter 13: Cambridge EQ

Note:

When operating at sample rates less than 44.1 kHz, the maximum fre-

quency will be limited.

Gain Knob

This parameter determines the amount by which the frequency setting for the
band is boosted or attenuated. The available range is ±20 dB.

Q (Bandwidth)

Knob

The behavior of the Q parameter varies depending on the band mode and
the gain. For this reason Q is detailed separately in the parametric and shelf
mode sections (see

“Parametric Q” on page 180

and

“Shelf Q” on

page 182

).

Parametric EQ

A band is in parametric mode when shelf mode is disabled (see

“Shelf Enable

Button” on page 182

). Three types of parametric EQ are available, as deter-

mined by the Parametric Type selector.

Parametric Type

Selector

The Parametric Type selector changes the response of the band
controls to reflect the behavior of various analog equalizers. It is
a global control for all 5 bands, and has no effect on the low

and high cut filters. Click the Parametric Type display to rotate between Types
I, II, and III.

The filter algorithm is the same in all three parametric types. The difference is
in the dependency between the gain and Q parameters. Each parametric
type has its own response characteristics.

In Type I mode, the Q remains constant regardless of the gain setting. In Type
II mode, the Q increases as gain is boosted, but remains constant as gain is
attenuated. In Type III mode, the Q increases as gain is boosted and attenu-
ated. See
