19.Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government's
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially danger-
ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres-
sure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here.

INTRODUCTION
Connecting and setting up the SR1530z is a breeze. It
accepts a line-level signal via a female XLR input jack.
A male XLR Thru jack is provided for daisy-chaining the
signal to additional SR1530z cabinets.
Three built-in power amplifiers provide 100 watts rms
each for the mid-frequency and high-frequency driv-
ers, and 300 watts rms for the low-frequency driver. The
amplifier modules sit on a mammoth aluminum heatsink
that eliminates the need for fans. A tremendous benefit
of having the amplifiers located within the loudspeaker
cabinet is that the SR1530z functions as a system, opti-
mizing acoustic, electronic, and mechanical designs to
achieve the highest level of performance and value.
The rear mounted amplifier assembly features:
· an input XLR and loop-through XLR
· Power ON indicator
· Protection indicator
The cabinet is constructed using both 18 mm multi-
layered plywood and pressure injected structural resin.
A carrying handle is integrated into each side for easy
loading and transport.
Thank you for choosing Mackie's active sound reinforce-
ment loudspeaker systems.
The SR1530z is a high-efficiency, extreme output,
horn-loaded, 3-way, wide-dispersion, active sound
reinforcement system. It features a one-piece 90º x 40º
horn, which includes both the mid- and high-frequency
sections in a proprietary optimized WavefrontTM design.
Unlike typical mid/high horn designs, the high-frequency
section is positioned to fire down into the 6-inch mid-
range's dispersion pattern. This creates a focused, single
wave front with excellent phase and power response
characteristics. The resulting 90º x 40º dispersion pat-
tern provides a very open, natural sound at extreme
output levels.
The 6-inch neodymium mid-range transducer oper-
ates between 700 Hz and 3000 Hz, eliminating the place-
ment of a crossover point in the middle of critical voice
frequencies. Frequencies above 3000 Hz are reproduced
by a 1-inch neodymium compression driver. The low fre-
quencies are produced by a high-output 15-inch woofer
with a X-inch high-temperature voice coil.

REAR PANEL DESCRIPTION
1. MAIN INPUT
This is a female XLR-type connector that accepts
a balanced line-level signal from a mixing console or
other signal source.
2. LOOP OUT
This is a male XLR-type connector that produces
exactly the same signal that is connected to the MAIN
INPUT jack. Use it to daisy-chain several SR1530z's
together off the same signal source.
3. Power ON Indicator
When the POWER switch is turned on, and the
linecord is connected to an active AC power supply, this
indicator lights green to let you know that you're ready
to rock and roll. The cool blue LED on the front of the
cabinet works in the same way.
4. PROTECTION Indicator
The SR1530z has a built-in limiter that prevents
the amplifier outputs from clipping or overdriving the
transducers. The PROTECTION indicatior lights when
the limiter is activated. It's okay for the PROTECTION
indicator to blink occasionally, but if it blinks frequently
or lights continuously, turn down the signal source's
level control until the PROTECTION indicator only
blinks occasionally.
There is also a thermal protection circuit that mon-
itors the internal temperature of the amplifiers and
heatsink. If the temperature should exceed a safe oper-
ating level, this indicator lights and the signal is muted to
allow the amplifiers to cool. When the temperature cools
to a safe level once again, the thermal protection circuit
deactivates and normal operation continues.
Note: Activation of the thermal protection circuit is
an indication that you should take steps to avoid con-
tinued thermal problems. See "Thermal Considerations"
on page 6.
5. POWER Switch
Use this switch to turn the SR1530z on and off. Make
sure the signal source's level control is turned down
before you turn it on.
6. AC Receptacle
This is where you connect the AC linecord to provide
AC power to the SR1530z's built-in power amplifiers.
Plug the linecord into an AC socket properly configured
for your particular model.

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 SR1530z 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 SR1530z'S
The SR1530z 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 SR1530z 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
SR1530z by its handles. The SR1530z
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 SR1530z), 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.
