6.2 Operational Check List

To operate a DSA loudspeaker, pre-performances checks and adjustments

should be made. In typical permanently installed applications, these

checks would normally be one-time, set-up adjustments that may only

need to be periodically verified. All of these steps require using DSAPilot.

1. Set the Power Management function as appropriate for your application.

2. Select each cluster in the DSAPilot design and verify the LED indicator

illuminates on the corresponding physical cluster.

3. Verify that the LED indicator on each enclosure is at the top or bottom

as shown in DSAPilot.

4. Adjust the input gain for each cluster for the desired nominal output

level for the expected input signal levels.

5. Adjust the input EQ for each cluster for the desired voicing to accom-

modate room acoustics, program content, or personal taste.

6. Adjust the input Limiting for each cluster to prevent higher than desired

output SPLs.

6.3 Normal Operation

6.3.1 POWERING UP

Power is applied to DSA in one of three ways:

1. Always On: Connect the loudspeaker to a continuously powered

AC mains supply. The loudspeaker is always ready for use. For

this mode, disable the Power Management function.

2. Off/On: Connect the loudspeaker to an AC mains supply which

is switched on and off between uses. The AC mains must be

switched on for each use. For this mode, disable the Power

Management function.

3. Standby/On: Connect the loudspeaker to a continuously powered

AC mains supply. The loudspeaker will be ready when input signal is

applied. For this mode, enable the Power Management function.

6.3.2 SIGNAL PROCESSING SETTINGS

When powered up, the signal processing in each loudspeaker will be set to

what it was for the previous use. The signal processing settings are

retained by non-volatile memory in each loudspeaker. This memory will

last indefinitely when connected to the AC mains. When disconnected

from AC mains, a battery supplies power to this memory. The expected

battery life without being connected to the AC mains is 10 years.
