2.Input Clip: If this indication is enabled, random flashing shows that the audio input signal is clipping the A to D converters at the input. To correct this condition, reduce the input signal level at the source. Because the input gain is after the A to D converters, the DSA input gain adjustment will have no effect on this condition. NOTE: This is likely an unusual condition because the LED will respond only if the input signal levels are greater than +24 dBu. It is recommended that this function normally be disabled.

3.Output Compressor/Limiter Active: If this indication is enabled, random flashing shows that the amplifier output compressor/limiters have been activated. Occasional flashing is acceptable. Flashing more than once every few seconds means the input signal level is too high. To correct this condition during a performance, reduce the input signal level at the signal source. If the source levels must normally be run at such levels, then reduce the DSA input gain using DSAPilot. Because of possible audio artifacts, this latter adjustment should not be done during a performance.

NOTE: It may be desirable to disable this indication to avoid the audience seeing flashing LEDs, particularly on dynamic program. In this case, determine the source level that triggers the Output Compressor/Limiters. Monitor and control the source level so as not to exceed this pre-determined trigger level. This will help prevent the DSA Output Compressor/Limiters from activating more than occasionally.

4.System Error: If this indication is enabled, flashing at regular intervals indicates a fault in the DSA’s electronics. Faults include malfunctioning amplifiers or DSPs, over temperature, and low battery. If a fault is indicated, use DSAPilot to determine the exact problem.

NOTE: A battery is used to retain the DSA’s settings when disconnected from the AC Mains. A low battery requires replacement by the EAW Service Department or the service department of the EAW Distributor for your country. Expected battery life is 10 years without being connected to the AC mains.

5.Identification: Using DSAPilot during initial system set-up, this function is used to physically identify with which cluster DSAPilot is communicating. Selecting a cluster or an individual loudspeaker within a cluster in DSAPilot will turn on the LEDs in the corresponding enclosures.
