[. . . ] When connecting a balanced signal, be sure it's wired per AES (Audio Engineering Society) standards: XLR TRS Hot (+) Pin Tip Cold (­) Pin Ring Shield (Ground) Pin 1 Shield There is also a male XLR connector labeled THRU. This allows you to connect more than one SRM50v to the output of your mixing console. Simply plug the signal source output into the first INPUT jack, and patch that speaker's THRU jack to the next INPUT jack, and so on, daisy-chaining multiple speakers (see diagram on page 7). The THRU jack's signal comes after the MIC/LINE switch, but before the LEVEL control. If the MIC/LINE switch is pushed in on the first SRM50v, the signal at the THRU jack is boosted by 0 dB to a line level. Therefore, leave the MIC/LINE switch out on the following SRM50vs in the chain. PLACEMENT The SRM50v active speakers are designed to sit on the floor, a tabletop, or to fit on a standard tripod speaker stand. They can also be suspended by the rigging points, which requires installing the optional hanging bracket on the top and/or bottom of the cabinet (SRM350v2 Bracket Kit: Part No. You can lay the cabinet down on its side and use the SRM50v as a floor monitor. The asymmetrical trapezoidal shape of the cabinet provides a perfect angle for aiming up toward performers from the front of the stage. As with any powered components, protect them from moisture. If you are setting them up outdoors, make sure they are under cover if you expect rain. Do not place it closer than two feet (0. 6 meters) from any TV set or computer monitor. Do not place any magnetic audio or video tapes or computer discs near the SRM50v. RoomAcoustics The SRM50v active speakers are designed to sound as neutral as possible; that is, to reproduce the input signal as accurately as possible, monitoring the sound rather than changing it. Room acoustics play a crucial role in the overall performance of a sound system. However, the wide high-frequency dispersion of the SRM50v helps to minimize the problems that typically arise.

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

If they are set up outdoors, be sure they are under cover if you expect rain or you live in Washington. · Avoid exposure to extreme cold (below freezing temperatures). If you must operate the active speakers in a cold environment, warm up the voice coils slowly by sending a low-level signal through them for about 15 minutes prior to high-power operation. [. . . ]
