6.3.3 OPERATION

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.

6.4 Operational ‘ DOS’ and ‘ DONTS’

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 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.

6.4.2 MAXIMUM OUTPUT

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.

6.4.3 FREQUENCY CONTENT

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.

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 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.
