Operation

Installation

Remove all packing materials from the MA-460. Check that all foam and plastic padding is removed.
Secure the equipment into a 19" rack. Connect all cables.

Set Up and Operation

Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate an 115V specification product on 230V power, or vice versa.
Before powering up the first time, make sure the AC-selector switch is set to the proper voltage.
Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty.
NOTE: Always turn off and disconnect the amplifier from mains voltage before making audio
connections. Also, as an extra precaution, have the attenuators turned down during
power-up.

Connecting Inputs

Use the XLR input connectors on the rear to supply audio signals to your DAP Audio PA-Series amplifier.
The connectors accept balanced and unbalanced audio connections. (The PA- Series amplifiers are
configured standard with "Pin 2 hot" on XLR inputs. For more Information, see the section on Connection
cables on page 12.

Connecting Outputs.

Speakers are connected using terminal connectors. See the examples below and following page.

Low impedance outputs

You can use as many speakers as you want as long as the total impedance matches the amplifiers
output.
Example 1: using the 4Ω output with two 8Ω speakers.
