Balanced XLR Connectors
If connecting an unbalanced signal to the SWA1501 balanced input, be sure that the signal high (hot) connection is wired to Pin 2 and the unbalanced ground connection is wired to the low and the ground connections of the balanced input (Pins 3 and 1). If there are
There are also four male XLR connectors labeled THRU (FULL RANGE OUTPUT) and 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 SWA1501 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,
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
PLACEMENT
The SWA1501 subwoofer is designed to sit on the floor or on sturdy stands.
A socket is provided on the top of the SWA1501 for mounting the Mackie SRM450 active speaker. Use the optional Mackie speaker mounting pole to mount the SRM450 on the SWA1501 (see Hookup Diagram on page 5).
As with any powered components, protect the SWA1501s 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 suspend the SWA1501 by its handles.
