Lend Me Your Ears
Exposure to extremely
high noise levels may cause
permanent hearing loss. In-
dividuals vary considerably
in susceptibility to noise-
induced hearing loss, but nearly everyone will
lose some hearing if exposed to sufficiently in-
tense noise for a period of time. The U.S.
Government’s Occupational Safety and Health
Administration (OSHA) has specified the per-
missible noise level exposures shown in this
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
these levels use hearing protectors while this
unit is in operation. Ear plugs or protectors in
the ear canals or over the ears must be worn
when operating this amplification system in
order to prevent a permanent hearing loss if
exposure is in excess of the limits set forth here.

INTRODUCTION
M•1400i and C300s. A Phase switch gives you
the option of reversing the polarity of the signal
to the full-range speakers by 180º. A Subwoofer
Level control allows you to adjust the balance be-
tween the subwoofer and the full-range speakers.
The built-in amplifier produces 600 watts of
continuous power. The amplifier module sits on
a mammoth heatsink that eliminates the need for
fans, dramatically extending life expectancy, and
eliminating maintenance cycles. A tremendous
benefit of having the amplifier located within the
subwoofer cabinet is that the SRS1500 functions
as a system, optimizing acoustic, electronic, and
mechanical designs to achieve the highest level of
performance and value.
The cabinet is constructed with 18mm thick
multi-layered birch plywood. Carrying handles
are integrated into each side for easy loading
and transport.

Thank you for choosing Mackie Designs’
active sound reinforcement speaker systems.
The SRS1500 is a high output active
subwoofer system. It features a high-precision
15˝ transducer combined with application
specific amplifier technology. The system is
composed of a single, compact subwoofer cabinet
with built-in control and amplifier electronics.
Connecting and setting up the SRS1500 is a
breeze. It accepts a stereo line-level signal via
female XLR input jacks. Male XLR Thru jacks
are provided for daisy-chaining the signal to
additional SRS1500 cabinets. The built-in
crossover separates the low frequencies from
the high frequencies, and routes the high fre-
quencies to the male XLR high-pass output
jacks. Connect these to the inputs of full-range
active speakers such as the Mackie Designs
SRM450s, or to an amplifier powering a pair of
passive speakers such as the Mackie Designs
