6.4 Operational ‘DOS’ and ‘DONT'S’

6.4.1 EQUALIZATION

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 inline with the DSAi input signal. DSA’s user input equalization, adjusted via DSAPilot, should be used only for overall tuning adjustments made during initial system set-up.

6.4.2 MAXIMUM OUTPUT

At the highest usable operating levels, the LED Indicator on the module 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.

6.4.3 FREQUENCY CONTENT

Do not attempt to boost low frequencies below about 100 Hz. The 4 in drivers DSAi module 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.

6.4.4 INPUT LIMITING

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.

6.4.5 DSAPILOT ADJUSTMENTS

Do not make adjustments using DSAPilot during normal operation. The reason is that changes to the DSAi module’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. Depending on the magnitude of any changes, sonic artifacts may result while the updates are taking place.
