Mackie MR4T Quick Start Guide

MONITOR MR4/MR4W

Compact Two-Way Speaker

The MR4 (Black) and MR4W (White) are a
compact two-way speaker system designed for
constant-impedance systems. The 5" carbon
fiber woofer mounted on a 120° x 100°
constant-directivity horn, in combination with
a 0.5" mylar dome tweeter, provide natural,
smooth sound reproduction, ideal for use in
business music systems and indoor/outdoor
background music applications.

The passive crossover is designed to reduce
heat dissipation and optimize the power
response of the loudspeaker. Connections are
made to recessed, color-coded spring-loaded
terminals.

The enclosure is constructed of high­density polystyrene, with integrated mounting
points for use with the optional mounting
hardware, and includes a protective
perforated steel grille.

Safety First!

Before connecting and using the equipment,
please read this Quick-Start Guide carefully
and keep it for future reference.

Hearing loss Hearing loss

Hearing loss - Exposure to high sound levels

Hearing loss Hearing loss
can cause permanent hearing loss. The sound
pressure level which leads to hearing loss
varies considerably from one person to
another, and depends on the duration of
exposure. The U.S. Government’s
Occupational Safety and Healt Administration
(OSHA) has established the maximum sound
pressure levels that can be with stood without
causing damage, which are shown in the table

below. According to the OSHA regulations,
any exposure over the maximum limits
indicated in the table can reduce the hearing
capacity of a person. To prevent potentially
dangerous exposure to high sound pressure
levels, anyone subjected to such levels must
use suitable protection. When a Mackie
Industrial product capable of producing high
sound levels is being used, it is therefore
necessary to wear ear plugs or protective
earphones when the limits shown in the table
are exceeded.

Consult the specifications provided in the
instruction manual to know the maximum
sound pressure (SPL) the speaker is capable
of producing.

Installation

1. Use these spring-loaded terminals to

connect the speaker wiring.

Connections

The spring-loaded speaker terminals are
designed to accept bare wire, up to a
maximum of 18 gauge. Strip 1/4" of insulation
off the end of the speaker wire, press in the
tab, and insert the bare wire into the hole.
When you release the tab, the wire is locked in
place. Make sure there are no stray strands of
wire outside the terminal connection.

The MONITOR MR4 can be mounted using
the optional mounting brackets. These include
the following:

MA5-6: Plate for suspending 4 clustered

speakers, Black

WARNING: Consult a professional rigger or
structural engineer prior to suspending
loudspeakers from a structure not intended
for that use. Always know the working load
limit of the structure supporting the
loudspeaker array. Always make sure that
the rigging hardware minimum rating is at
least five times the actual load.
