Horn Rotation Instructions • The high-frequency horn can be rotated through 90 degrees to allow you to choose the best horn pattern for your installation. From the factory, the horn is set to give a 90 degrees horizontal pattern if the loudspeaker is mounted vertically. If you mount the loudspeaker horizontally, you can rotate the horn through 90 degrees to compensate. This is done as follows: 1. Using a medium phillips screwdriver, remove the 18 screws attaching the grille to the enclosure

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
