Quick Start - Mackie MR10Smk3 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.
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").
4. Connect the line-level signal from the output [5] jacks
on the MR10Smk3 Studio Subwoofer (1⁄4") to the studio
monitors' input jacks.
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).
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.
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 reproduction.
A lot of factors can conspire to thwart the
MR10Smk3s' extended low frequency – including room
shape, room volume and acoustical 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:
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.
Additional Tidbits of Wisdom
• 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!
