Exposure to extremely

high noise levels may

cause permanent hear-

ing loss. In di vid u als vary

considerably in sus cep ti -

bil i ty to noise-in duced hearing loss, but nearly

everyone will lose some hearing if ex posed to

sufﬁ ciently in tense noise for a pe ri od of time.

The U.S. Gov ern ment’s Oc cu pa tion al Safety and

Health Ad min is tra tion (OSHA) has spec i ﬁ ed

the per mis si ble noise lev el 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 dan-

gerous exposure to high sound-pressure levels,

it is recommend ed that all persons exposed to

equipment capable of producing these levels use

hearing protectors while this unit is in opera-

tion. Ear plugs or protectors in the ear canals or

over the ears must be worn when operating this

ampliﬁ cation system in order to prevent a per-

manent hearing loss if exposure is in excess of

the limits set forth here.

INTRODUCTION

Thank you for choosing Mackie’s ac tive

sound reinforcement speaker sys tems.

The SWA1801 is a high-output active sub-

woofer system. It features a high-pre ci sion 18"

transducer combined with application-spe ciﬁ c

ampliﬁ er technology. The system is com posed of

a single, com pact subwoofer cab i net with built-in

control and am pli ﬁ er elec tron ics.

Connecting and setting up the SWA1801 is

a breeze. It accepts a stereo or mono line-level

sig nal via fe male XLR input jacks. Male XLR

Thru jacks are provided for daisy-chain ing the

signal to ad di tion al SWA1801 cabinets. The

built-in cross over separates the low fre quen cies

from the high fre quen cies, and routes the high

fre quen cies to the male XLR high-pass output

jacks. Connect these to the in puts of full-range

active speak ers such as the Mackie SA1521s,

or to an ampliﬁ er pow er ing a pair of pas sive

speak ers such as a combination of the Mackie

M•1400i and C300s. A Phase switch gives you the

option of reversing the po lar i ty of the sig nal to the

subwoofer by 180º. A Subwoofer Level con trol

al lows you to adjust the bal ance be tween the sub-

woofer and the full-range speak ers.

The built-in ampliﬁ er produces 800 watts of

con tin u ous power. The ampliﬁ er module sits on

a heatsink that elim i nat es the need for fans,

dra mat i cal ly ex tend ing life ex pect an cy, and elim i -

nat ing main te nance cycles. A tre men dous ben e ﬁ t

of hav ing the ampliﬁ er located with in the subwoofer

cab i net is that the SWA1801 func tions as a sys tem,

op ti miz ing acous tic, elec tron ic, and me chan i cal

de signs to achieve the high est level of per for mance

and val ue.

The cabinet is constructed with 15 mm thick

multi-layered birch plywood. Carrying han dles are

in te grat ed into each side for easy loading, and cast-

ers are attached to the rear for easy trans port.
