Mackie MR10Smk3 Owners Manual - Page 5

Owner's Manual Quick Start We realize that you can't wait to hook up your MR10Smk3 Studio Subwoofer and try it out. Nevertheless, please take the time to read this page NOW, and the rest can wait until you're good and ready. 1. Turn the input level [9] control on the back of the cabinet down (fully counterclockwise) before turning on the subwoofer for the first time. 2. Set the power switch [3] on the back panel off. This will prevent you from accidentally connecting a hot signal source to the subwoofer and getting a rude surprise. An Extremely Important Note on MR10Smk3 Bass Response and Your Control Room MR10Smk3s achieve the best bass ­response in a room that's optimized for bass r­ eproduction. A lot of factors can conspire to thwart the MR10Smk3s' extended low frequency - including room shape, room volume and a­ coustical treatment. This is not a cop-out or an apology. It's plain old physics in action. Luckily we've armed you with some compensating controls that you can use to optimize the frequency response of the speakers in your particular room. Consider the following: 3. Connect the L/R line-level signal from your mixer, interface, or other signal source to the input [4] jacks on the MR10Smk3 Studio Subwoofer (XLR or 1⁄4"). When you put your MR10Smk3s in a corner or up against walls, their bass characteristics change. The apparent loudness of the low frequencies increases when the subwoofers are placed close to a wall, and even more so when they are placed in a corner. 4. Connect the line-level signal from the output [5] jacks on the MR10Smk3 Studio Subwoofer (1⁄4") to the studio monitors' input jacks. Additional Tidbits of Wisdom 5. Connect the supplied AC power cord to the IEC socket [1] on the back of the subwoofer. Plug the other end into an AC outlet properly configured with the voltage corresponding to the markings next to the IEC socket. 6. Start your signal source (8-track player, turntable, CD player, DAW, or whatever), but leave the master volume control on the mixer or preamp down. 7. Turn on the power switch [3] on the MR10Smk3. 8. Slowly turn up the input level [9] control on the back of the subwoofer to center position (12 o'clock, aka unity gain). • Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection. • When you shut down your equipment, turn off the MR10Smk3 studio subwoofers first to prevent thumps and other noises generated by any upstream equipment from coming out the speakers. When powering up, turn on the subwoofers last. • Save the shipping box! You may need it someday. • Save your sales receipt in a safe place. It's your warranty! 9. Adjust the master volume on the mixer or preamp to a comfortably loud listening level. 10. Balance the subwoofer to your desired low-frequency output level and adjust the crossover [8] to your desired setting. Enjoy the authoritative, commanding lows of the MR10Smk3. Then read the rest of this manual. Owner's Manual 5
