HOOKUP DIAGRAM

Balanced XLR Connectors

There is also a male XLR connector labeled LOOP

OUT. This is also wired according to the above AES
standard.

The LOOP OUT connector allows you to connect

more than one SR1522z to your system. Simply plug the
signal source (i.e., mixer output) into the first MAIN
INPUT jack, and patch that speaker’s LOOP OUT jack
to the next MAIN INPUT jack, and so on, daisy-chaining
multiple speakers.

CONNECTIONS

DAISY-CHAINING MULTIPLE SR1522z'

The SR1522z has one female XLR input that accepts

a balanced line-level signal. When connecting a balanced
signal, be sure it’s wired per AES (Audio Engineering
Society) standards:

XLR

Hot (+)

Pin 2

Cold (–)

Pin 3

Shield (Ground) Pin 1

The LOOP OUT jack is wired straight from the MAIN

INPUT connector — there is no electronic circuitry
between — so the signal coming out of the LOOP OUT
jack is exactly the same as the signal going in.

PLACEMENT

The SR1522z speaker is designed to sit on the floor or

stage.

WARNING: The cabinet has no rig-
ging points and is not suitable for rig-
ging.

NEVER attempt to suspend the

SR1522z by its handles. The SR1522z
should never be pole-mounted.

You can create a horizontal array by placing the cabi-

nets side-by-side. However, you should have a good un-
derstanding of the relationship between the splay angle
(the angle between the facing sides of the cabinets),
the on-axis power, and frequency cancellation effects
between cabinets.

When two cabinets are placed side-by-side, the actual

splay angle is 20º (determined by a 10º angle on each
cabinet side). As the splay angle increases toward the
angle of horizontal coverage (90º for the SR1522z), the
on-axis power decreases, but the frequency response
becomes smoother as the comb-filtering effects (caused
by the interaction in the area of double-coverage)
decrease.

As with any powered components,
protect them from moisture. If you
are setting them up outdoors, make
sure they are under cover if you
expect rain.
