11.

Only use attachments/accessories specified by the manufacturer.

12.

Use only with a cart, stand, tripod, bracket, or

PORTABLE CART

table specified by the manufacturer, or sold with
the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to
avoid injury from tip-over.

13.

Unplug this apparatus during lightning storms or

when unused for long periods of time.

14.

Refer all servicing to qualified service personnel. Servicing is required

when the apparatus has been damaged in any way, such as power­supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.

15.

This apparatus shall not be exposed to dripping or splashing, and no

object filled with liquids, such as vases or beer glasses, shall be placed
on the apparatus.

16.

Do not overload wall outlets and extension cords as this can result in a

risk of fire or electric shock.

17.

This apparatus has been designed with Class-I construction and must

be connected to a mains socket outlet with a protective earthing con­nection (the third grounding prong).

18.

This apparatus has been equipped with a rocker-style AC mains power

switch. This switch is located on the rear panel and should remain
readily accessible to the user.

19.

The MAINS plug or an appliance coupler is used as the disconnect
device, so the disconnect device shall remain readily operable.

CAUTION

RISK OF ELECTRIC SHOCK! DO NOT OPEN!

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT

REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED PERSONNEL.

The lightning flash with arrowhead symbol within
an equilateral triangle is intended to alert the user
to the prescence of uninsulated “dangerous voltage”
within the product’s enclosure, that may be of significant magnitude
to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is
intended to alert the user of the prescence of important
operating and maintaining (servicing) instructions in the
literature accompanying the appliance.

WARNING

20. NOTE: This equipment has been tested and found to comply with

the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equip­ment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

CAUTION: Changes or modifications to this device not expressly

approved by LOUD Technologies Inc. could void the user's authority to
operate the equipment under FCC rules.

21. This apparatus does not exceed the Class A/Class B (whichever is

applicable)

limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.

ATTENTION — Le présent appareil numérique n’émet pas de bruits

radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans le
réglement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.

22.

Exposure to extremely high noise levels may cause permanent hearing

loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits

could result in some hearing loss. To ensure against potentially danger­ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres­sure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here:

Quick Start

Owner’s Manual

An Extremely Important Note

We realize that you can’t wait to hook up your
MR10Smk3
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

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
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.

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.

CD player, DAW, or whatever), but leave the master
volume control on the mixer or preamp down.
