Operate DSA 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 signal processing, set using DSAPilot, should not be used for in performance adjustments.

If equalization is required for tailoring the frequency response during performances, use an external equalizer such as a good quality 1/3 octave graphic equalizer, for this purpose. Connect the equalizer in- line with the DSA input signal. The DSA input equalization, adjusted via DSAPilot, should be used only for overall tuning adjustments made during initial system set-up.

At the highest usable operating levels, the LED Indicator on the loudspeaker and in the level meters in DSAPilot should show no more than occasional clipping. Occasional clipping means the LED indicator, if enabled, and DSAPilot meter will indicate clipping at most once every few seconds.

Do not attempt to boost low frequencies below about 100 Hz. The 4 in drivers DSA loudspeaker are not designed to replace subwoofers if strong, very low frequency response is needed. Boosts below 100 Hz can greatly increase the cone excursion and can use up much of the amplifier power available. These conditions can significantly reduce the overall maximum output.

The input limiting should not be used for driver protection. There is fixed, internal compression and limiting to help prevent driver damage from excessive amplifier output levels. These limiters will automatically activate in the presence of excessive signals. The LED indicator can be enabled to indicate activation of the protection circuits. See Section 6.1.2.

Do not make adjustments using DSAPilot during normal operation. The reason is that changes to the DSA loudspeaker’s electronics requires successively updating all internal parameters. Because there is a complete DSP engine for each transducer, updates can take a noticeable amount of time. Also depending on the magnitude of any changes, sonic artifacts may result while the updates are taking place.
