The PA2 Processing Modules & Parameters

This section of the manual provides descriptions of all the processing modules available in the DriveRack PA2 and their

associated parameters.

Graphic EQ (GEQ)

The 31-band GEQ module lets you manually tune the sound system’s frequency response and is meant to be used alone or

alongside the AutoEQ PEQ (which is set when you run the AutoEQ). In previous DriveRack models, the GEQ was set when you

ran the AutoEQ. AutoEQ in the PA2 now uses its own dedicated 8-band parameteric EQ (referred to as the “AutoEQ PEQ”) for

system equalization, freeing up the GEQ for custom-tuning tasks. Use AutoEQ to tune the system at the venue, then use the

GEQ to shape the system’s tone to taste by ear.

Typically, a flattened sound system will sound light on the bottom end. The PA2’s AutoEQ TARGET parameter compensates for

this by automatically applying bass boost – see ‘WIZARD OPTIONS’ on page 16 for further information on the AutoEQ

TARGET parameter. However, if the AutoEQ TARGET parmeter is set to FLAT, you could use the GEQ instead to tailor the low

end to your liking. This allows you to add some of that bottom end back in, while still maintaining the “flat” reference point (just

bypass the GEQ and the system is back to your flat reference point). Let’s say you have a DJ rig and also prefer a little more

“sizzle” on the top end. Just raise the high-frequency bands in the GEQ to add some extra top end to the system.

The built-in GEQ “Quick Curves” allow you to quickly alter the frequency response of the system. Try auditioning each option

to see which one works best for your application. You can then manually edit any GEQ bands from there if further adjustments

are required.

The GEQ can be configured for dual mono or stereo linked operation. See ‘Using The Wizards’ on page 14 for more

information on this option.

GEQ Parameters

The Graphic EQ menu can be accessed by pressing the GEQ button. Turn the DATA wheel to scroll through the list of

parameters. Press the DATA wheel to edit a selection.

GRAPHIC EQ [ON, OFF]

This parameter turns the GEQ module on and off.

QUICK CURVE [MANUAL, FLAT, MY BAND, SPEECH, PERFORMANCE, DJ]

This parameter allows you to select from preset EQ curves. Note that you can select one of these Quick Curves and then

further edit the individual GEQ bands manually from there if required. The following Quick Curve options are available:

• MANUAL (Restore)

This option is used for getting back to your original GEQ settings in the event that you change the Quick Curve option. For

example, if you’ve already configured the GEQ and you then select the FLAT Quick Curve option, the GEQ will be flattened

(all bands set to 0 dB). By then selecting the MANUAL Quick Curve option, the GEQ settings you had prior to selecting the

FLAT option will be restored. Note that previous settings cannot be restored after a power cycle or after recalling a different

preset.

• FLAT

Select this option to reset all GEQ bands to 0 dB (flat).
