4 INTRODUCTION Thank you for choosing LOUD T echnologies’ Mackie active sound r einforcement speakers. The SRM350 is an active tw o-way loud- speaker capable of e xtremely high sound pressur e lev els, and designed to give you the best performance of any loudspeak er in its class and price range .
5 The Crossover The built-in electr onic crosso ver is a 24 dB/octa ve Linkwitz-Riley design. Although more e xpensive than other crosso ver designs, the benefits pro vided by the Linkwitz-Rile y design hav e been w ell documented.
6 HOOKUP DIAGRAMS Quick Start 1. Start with the follo wing settings on the back of the SRM350: Turn the POWER switch off (do wn). Set t h e CONTOUR and MIC/LINE switches out. If using a microphone as the input to the SRM350, push the MIC/ LINE switch in.

8 REAR P ANEL DESCRIPTION CONTOUR Pushing in this switch engages a filter that pr ovides 3 dB of boost to the lo w and high frequencies (belo w 100 Hz and abo ve 12 kHz).
9 F ollow the Quick Start guide on page 6 for setting the LEVEL control. F or most ap- plications, it will be in the NORMAL position (12 o’clock) . If you ha ve a particu- larly high line-lev el signal connected to the SRM350, you ma y need to turn the control down to the 9 o’clock position.
10 PLACEMENT The SRM350 active speak ers are designed to sit on the floor , a tabletop, or to fit on a standar d tripod speaker stand. They can also be suspended by the rigging points, which r equires installing the optional hanging brack et on the top and/or bottom of the cabinet.
11 Here ar e some useful placement tips: • A void placing loudspeakers in the corners of a room. This incr eases the low-fr equency output and can cause the sound to be muddy and indistinct. • A void placing loudspeak ers against a wall. This, too, increases the lo w-frequency output, though not as much as corner placement.
12 AC POWER CONSIDERA TIONS Be sure the SRM350 is plugged into an outlet that is able to supply the corr ect volt- age specified for y our model. If the voltage should drop belo w 97% of the specified line voltage , the built-in amplifiers will no longer be able to supply r ated pow er .
13 Where ver possible , connect all of your equipment to the same electrical cir cuit. This will help reduce the possibility of a ground loop pr oblem causing an annoying hum in your speak ers. Low po wer components such as tape decks, mixers, effects pr ocessors and CD play ers should be connected to the same outlet as the SRM350s.
