Operational Check List, Normal Operation

6.2 Operational Check List

To operate a DSAi module, 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 accommodate 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 DSAi in one of three ways:

1.Always On: Connect the module to a continuously powered ac mains supply. The module is always ready for use. For this mode, disable the Power Management function.

2.Off/On: Connect the module 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 module to a continuously powered ac mains supply. The module 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 module will be set to what it was for the previous use. The signal processing settings are retained by non-volatile memory in each module. 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.

6.3.3 OPERATION

Operate DSAi similarly to any other loudspeaker. This normally involves setting the source levels to achieve the desired output as well as applying external equalization or other signal processing to achieve certain desired results. DSA’s internal user signal processing, set using DSAPilot, should not be used for in performance adjustments.
