Parametric EQ (AutoEQ, HIGH, MID, LOW PEQ)

There are two types of PEQs available in the PA2: the AutoEQ PEQ and the output PEQs (labeled LOW, MID, and HIGH).

The AutoEQ PEQ is an 8-band parametric EQ which resides in the input processing side of the PA2 (pre crossover) and

is automatically adjusted by the built-in AutoEQ Wizard. In most cases you will likely just look at the settings in the AutoEQ

PEQ to see how the system was equalized after running the AutoEQ Wizard. However, you can go into the AutoEQ PEQ and

manually adjust the settings if desired.

The 8-band HIGH, MID, and LOW PEQs reside in the output processing side of the PA2 (post crossover) and were designed

to be used exclusively for speaker tunings. In a perfect world, your loudspeaker drivers would exhibit ultra-flat frequency

response (what you put in, you get out). Unfortunately, loudspeaker drivers don’t have extremely flat frequency response by

design and require some help to achieve a more flat frequency response. The output PEQs allow you to compensate for this

fact and improve the frequency response of the loudspeaker system, before taking the room into account.

If your main and sub speaker models are available in the Setup Wizard, the output PEQs will automatically be set when you

select them. By applying speaker tuning EQ, loudspeaker frequency response can be improved. Keep in mind that selecting

some speaker models in the Setup Wizard won’t set any parametric EQ settings, so don’t be alarmed if you selected your

speakers in the Setup Wizard and no PEQ settings were set. These output PEQs can also be adjusted, so you can manually

enter speaker tuning parameters if your speakers aren’t listed and speaker tuning data sheets are available for your speaker

models.

PEQ Parameters

The PEQ menus can be accessed by pressing the PEQ button. You will see a list of the available PEQs to select from. Which

options are available in the list will depend upon the current configuration. In all cases you will at least see the AutoEQ PEQ

and HIGH OUTPUT PEQ. If you’ve configured a 2-way system, you will also see a LOW OUTPUT PEQ. If you’ve configured

a 3-way system, you will see an additional MID OUTPUT PEQ. Turn then press the DATA wheel to select the desired PEQ

module. Turn the DATA wheel to scroll through the list of parameters. Press the DATA wheel to edit a selection. When in the

PEQ menu, pressing and holding the PEQ button for approximately 2 seconds will advance to the next active PEQ module

from the list, wrapping around through the available modules.

•

AutoEQ/PARAMETRIC EQ [ON, OFF]

Turns the selected PEQ module on or off.

• FLATTEN [RESTORE, FLAT, MANUAL, AUTOEQ (AutoEQ Only)]

This parameter has two options in the output PEQs: RESTORE and FLAT. Select the FLAT option to zero out the selected

PEQ (set all bands to 0 dB). Select the RESTORE option to retrieve the settings you had before you selected the FLAT

option.

The AutoEQ PEQ provides three options: FLAT, MANUAL, and AUTOEQ. Select the FLAT option to zero out the AutoEQ

PEQ (set all bands to 0 dB). The MANUAL option shows any manual adjustments you have made to the AutoEQ PEQ –

if you haven’t made any, the PEQ will be flat when the MANUAL option is selected. If you have manually edited AutoEQ

settings, selecting the AUTOEQ option will restore the PEQ settings that were set by the AutoEQ Wizard.

• BAND(1–8) TYPE [BELL, LOW SHELF, HIGH SHELF]

This parameter selects the PEQ filter type. Use the BELL type to edit a range of frequencies, the LOW SHELF type to edit

all frequencies below a specified frequency, or the HIGH SHELF type to edit all frequencies above a specified frequency.

Each band (1–8) allows you to select between these three band types, so any band can be a bell or shelving type filter.
