Equalizer

Equalizer off Set

A 4-band parametric equalizer providing optional Boost/Cut (“PEQ”) or

Notch filtering is available for each channel independently in the signal

path before the limiting circuit. The EQ function has a Master on/off

while each of the four bands can be switched independently. In Dual

channel or Mix Top/Sub mode the EQ sections of both channels can be

linked using the "Link A»B" function in the "Settings menu".

Note:

If several EQ bands are set with a high boost in the same

frequency range, this may cause overflows within the

DSP. These errors are recognized internally and the D12

will mute the channel. The error message "DSP Error 16" is

displayed. The error can be cleared by changing the filters

or by switching off the EQ function.

Set

Selecting "Set" enters the submenu and gives access to the four EQ

bands. Turning the encoder to right and pushing the encoder gives

access to the individual EQ bands.

on/off

In the submenu "Set" the master switch for the EQ function is also

accessible.

EQ [number]

Turning and pushing the encoder in at least one of the EQs allows direct

access to the individual EQ filters without the necessity to revert to the

"Set menu".

off/PEQ/Notch

Pushing the encoder enables selection of either the "off", "PEQ"

(Parametric Equalizer) or "Notch" function.

The status of the respective EQ band is indicated as follows:

— The respective EQ Band is switched "off" (flat)

P The respective EQ Band is switched to "PEQ" function

N The respective EQ Band is switched "Notch" function

The resulting overall frequency response of all (active) filters is shown at

the bottom of the display.

Parametric Equalizer (PEQ)

The following parameters can be edited:

Filter center frequency adjustable from 20 Hz to 20 kHz in 3 % steps.

The Q of the filter is adjustable from 0.5 ... 25 in 10 % steps. In

addition, the bandwidth (BW) as a result of the Q is displayed as a

value (2.0 ... 0.04 octaves) in a non-editable field.

Gain, adjustable from –18 dB to +6 dB in 0.2 dB steps.
