MACKIE SWA2801z - Manual (Page 6)

CONNECTIONS
The SWA801z has two female XLR inputs
that accept a balanced line-level signal. When
connecting a balanced signal, be sure it’s
wired per AES (Audio Engineering Society)
standards:
XLR
Hot (+) Pin
Cold (–) Pin
Shield (Ground) Pin 1
Balanced XLR Connectors
If connecting an unbalanced signal to the
SWA801z balanced input, be sure that the
signal high (hot) connection is wired to Pin
and the unbalanced ground connection
is wired to the low and the ground connec-
tions of the balanced input (Pins and 1).
If there are ground-loop problems, try con-
necting the unbalanced ground connection
only to the input low connection (Pin ),
and leaving the input ground connection
disconnected.
There are also two male XLR connectors
labeled THRU (FULL RANGE OUTPUT) and
two labeled HIGH PASS (MID/HIGH FREQ)
OUTPUT
. These are also wired according
to the AES standard.
The THRU output connectors allow you
to connect more than one SWA801z to
your system. Simply plug the signal source
(i.e., mixer output) into the first speaker’s
FULL RANGE INPUT
jacks, and patch that
speaker’s THRU jacks to the next speaker’s
INPUT
jacks, and so on, daisy-chaining mul-
tiple speakers.
The THRU jack is wired straight from the
FULL RANGE INPUT connector — there is no
electronic circuitry between — so the signal
coming out of the THRU jack is exactly the
same as the signal going in.
The HIGH PASS OUTPUT jacks provide
a line-level signal of the frequencies above
10Hz that you connect to a pair of active
speakers (or to a stereo amplifier powering
a pair of passive speakers).
PLACEMENT
The SWA801z subwoofer is designed to
sit on the floor, either upright or on its side.
(Feet are provided on the bottom and on
one side.) A socket is provided on the top
and one side of the SWA801z for mount-
ing the Mackie SA151z or SRM50 active
speakers. Use the optional Mackie speaker
mounting pole (SPM100) to mount them
on the SWA801z (see Hookup Diagram on
page 5).
As with any powered
components, protect the
SWA801z from exposure
to moisture. If you are
setting them up outdoors,
make sure they are under
cover if you expect rain.
WARNING: The cabinet
has no rigging points and
is not suitable for rigging.
NEVER attempt to sus-
pend the SWA801z by
its handles.
