Here are some useful placement tips:

•Avoid placing loudspeakers in the corners of a room.

This increases the low-frequency output and can cause the sound to be muddy and indistinct.

•Avoid placing loudspeakers against a wall. This, too, increases the low-frequency output, though not as much as corner placement. However, if you do need to reinforce the low frequencies, this is a good way to do it.

•Avoid placing the active speakers directly on a hollow stage floor. A hollow stage can resonate at certain frequencies, causing peaks and dips in the frequency response of the room. It’s better to place the active speakers on a sturdy table or tripod stands.

•Position the active speakers so the high-frequency drivers are 2 to 4 feet above ear level for the audience (make allowances for a standing/dancing in the aisles audience). High frequencies are highly directional and tend to be absorbed much easier than lower frequencies. By providing direct line-of-sight from the active speakers to the audience, you increase the overall brightness and intelligibility of the sound system.

•Highly reverberant rooms, like many gymnasiums and auditoriums, are a nightmare for sound system intelligibility. Multiple reflections off the hard walls, ceiling, and floor play havoc with the sound. Depending on the situation, you may be able to take some steps to minimize the reflections, such as putting carpeting on the floors, closing draperies to cover large glass windows, or hanging tapestries or other materials on the walls to absorb some of the sound.

However, in most cases, these remedies are not possible or practical. So what do you do? Making the sound system louder generally doesn’t work because the reflections become louder, too. The best approach is to provide as much direct sound coverage to the audience as possible. The farther away you are from the speaker, the more prominent will be the reflected sound.

Use more speakers strategically placed so they are closer to the back of the audience. If the distance between the front and back speakers is more than about 100 feet, you should use a delay processor to time-align the sound. (Since sound travels about 1 foot per millisecond, it takes about 1/10 of a second to travel 100 feet).

RIGGING

The SRM350v2 cabinets are fitted with four M5 insert points on the top and bottom for installing an optional hanging bracket that allows the speaker to be flown.

SRM350v2 Bracket Kit: Part No. 0016404

WARNING: Never attempt to suspend the SRM350v2 active speakers by their handles. If you want to suspend them, use the hanging brackets only.

If you are hanging them in an inaccessible place, such as over a lion’s cage, make sure that you first complete the sound check and set the SRM350v2 LEVEL correctly.
