6. Input Switches

These switches are recessed to prevent accidental switching. You may need to use the tip of your fingernail or an object

with a pointy tip, such as a pen, to activate these switches.

• +4dBu/-10dBv Switch

This switch sets the PA2’s input sensitivity. Select the +4dBu option (switch out) when connecting a mixer or device

which has a nominal output operating level of around +4dBu. Select the -10dBV option (switch in) when connecting

a mixer or device which operates at a lower “consumer” level, such as some DJ mixers or a consumer device with

unbalanced output connectors (such as RCA connectors). If you’re not sure what the nominal output operating level

of your mixer is, check the product’s manual or contact the manufacturer. It’s advisable to only switch this switch

when your amplifiers are powered off or the DriveRack PA2’s outputs are muted.

• Ground Lift Switch

The ground lift switch lifts the pin 1 chassis ground on both input XLR connectors. In most applications, this switch

should be left in the out (disabled) position. If hum becomes an issue and is caused from a ground loop between

your mixer and PA2, try engaging this switch. It’s advisable to only switch this switch when your amplifiers are

powered off or the DriveRack PA2’s outputs are muted.
