5. OPERATION

Signal Processing

Sometimes external signal processing is desirable to “voice” the loudspeaker to accommodate particular program material, less than optimum acoustics, feedback control, or personal taste. For these purposes, use a suitable electronic signal processor. This can be as simple as a 1/3 octave graphic equalizer or a fully capable DSP (digital signal processor) such as the EAW Commercial DX810, or the EAW MX8750.

Choosing a Power Amplifier

There is no exact answer to the question of what amplifier size you should use for a

loudspeaker. The loudspeaker power rating in EAW Commercial’s specifications only means it has passed a standard power test. This provides a rating that can be used as a point of comparison with other loudspeakers. This rating does not necessarily correspond to the best amplifier size to use nor is it a measure of a “safe” amplifier size to use. Rather, the amplifier should be sized according to both the sound levels required and the type of audio signals that will be reproduced. If you are unsure of how to determine this, consult with a qualified professional or contact EAW Commercial Technical Support.

Preventing damage to the loudspeaker is a function of operating your audio system so that the loudspeaker is not stressed beyond its design limits.

Operating Tips

•Do NOT drive any of your electronic equipment into clipping, particularly the power amplifiers. This can easily damage the loudspeaker.

•If driven into clipping, even an amplifier with a power output rating lower than the loudspeaker’s power rating can cause damage to a loudspeaker.

•Avoid sustained microphone feedback. This can quickly cause failure of high- frequency drivers.

•Avoid extreme boosts on equalizers as these can cause excessive input to the drivers at the boosted frequencies. Generally, cutting frequencies is preferred to adjust the frequency response.

•With appropriate signal processing, your loudspeaker should produce exceptionally good sound. If it is used in a room with problematic acoustics, there is little you can do to overcome the room problems with electronic adjustments. Your best solution is careful placement and aiming of the loudspeaker so most of the sound is directed only at the audience.

•Most EAW Commercial loudspeakers are capable of sound levels that can be damaging to human hearing. Take precautions so that audiences are not exposed to such levels. If you must expose yourself to these kinds of volume levels, wear adequate hearing protection.

•Take care when moving or lifting the loudspeaker. Injury to you or damage to the loudspeaker can result from careless handling.
