choosing an amplifier to drive your PAH series speaker. While it is true that an amplifier with a higher power rating can damage the drivers, under- powering can be even more dangerous. When an amplifier is overdriven and starts distorting, it generates transient frequencies that are much louder than the program material. These wayward frequencies could damage your speaker. A proper match is an amplifier which could drive the speaker up to the cabinet’s RMS rating, without exceeding the amplifier’s own RMS level.

Operation

When powering on your equipment, make sure the volume level on the amplifier is turned all the way down. This is to avoid the “popping” noise, which could damage your speaker.

The placement of speakers can be a bit tricky. Besides for the practical considerations, there are acoustic issues as well. Avoid placing the speaker in a corner, as this will cause the low frequencies to sound “muddy”. Similarly, but to a lesser degree, placing the speaker directly against the wall will exaggerate the low frequencies. You should therefore try to place your speaker so that it is a few feet away from the wall.

High frequencies are unidirectional while low frequencies are omni directional. Being that this is a full range enclosure, it is important that the speaker be placed so that the high frequencies reach the intended listeners properly. Make certain that no person or object could come to interrupt the line-of-site between the loudspeaker and the audience.

When using more than one loudspeaker, you have to account for phase alignment. When the speakers are close together this is not usually an issue. However, when they are far apart, the sound from one speaker may reach the ear a fraction of a second before the other. This will cause certain frequencies to cancel out, resulting in a hollow sound. To avoid this, you may have to use a delay processor to align the sound from the speakers.
