Installing The DriveRack PA2

Installation Recommendations

FOR RACK MOUNT USE ONLY. Install the PA2 in your 19” rack with the provided rack screws. When installed in a rack, make

sure there is proper ventilation. The sides and back of the device should be free of any obstruction that would prevent airflow.

The PA2 should not be mounted above or below anything that generates excessive heat. Ambient temperatures should not

exceed 95

F (35

C) when equipment is in use. Although the unit is shielded against radio frequency and electromagnetic

interference, extremely high fields of RF and EMI should be avoided where possible.

Making Connections

Audio Connections

1� Ensure the power is turned off on all interconnecting equipment and the PA2 before making audio connections.

2� See ‘Application Guide’ on page 50 for application notes and system diagrams which can be used for reference

when connecting the PA2 to your system. See ‘Cable Diagrams’ on page 61 for information on cabling.

3� Connect the outputs of your mixing console to the inputs of the PA2.

NOTE: The +4dBu/-10dBV switch on the back panel of the PA2 must be set to the correct position for your

application in order to avoid performance issues. +4dBu is referred to as “pro level” and will be the correct setting for

most applications, as most pro and semi-pro mixers will output a nominal level of around +4dBu. -10dBV is referred

to as “consumer level” and will need to be used when connecting a source which has an output level approximately 12

dB lower than pro level equipment.

4� Connect the PA2’s outputs to the designated amplifier or powered speaker inputs.

5� If you plan to calibrate the system using the built-in Wizards, connect the optional dbx RTA-M measurement microphone

using a microphone cable of suitable length and place it in a microphone stand.
