limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his
own expense.

ATTENTION
— Le présent appareil numérique n’émet pas de bruits
radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans
le réglement sur le brouillage radioélectrique édicté par les ministere
des communications du Canada.
25. 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 suciently 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 dangerous
exposure to high sound pressure levels, it is recommended that all persons
exposed to equipment capable of producing high sound pressure 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:
Duration, per
day in hours
8 90 Duo in small club
6 92
4 95 Subway Train
3 97
2 00 Very loud classical music

Introduction
Getting Started
The SR8S 8" 600W Professional Powered Subwoofer
is designed for real-world working musicians, DJs, events,
venues, and beyond.
The latest acoustic processing technology, powerful
amplification, and versatile configurations deliver incredible
sound and unbeatable reliability. Custom Voicing modes and
a variable crossover makes optimization for your system easy.
Built-Like-A-Tank™ construction features a rugged wood
cabinet and tough steel grille that is built to last.
A perfect complement to the SRT Series, SRM | V-Class Series
or any PA, SR8S not only adds powerful low end, but allows
for a massive increase in eciency and output for your whole
system.
How to Use This Manual:
Afer this introduction, a getting started guide will help
you get things set up fast. The hookup diagrams show
some typical SR8S subwoofer setups.
This icon marks information that is critically
important or unique! For your own good, read and
SR18S 18" 1600W Professional Powered Subwoofer
remember them...it is a good idea to pay special
attention to these areas in the Owner’s Manual
marked with the “VERY IMPORTANT” hand icon.
The following steps will help you set up the SR8S quickly.
If using SRT Series loudspeakers, please refer to page 3.
. Make all initial connections with the power switches
OFF on all equipment. Make sure the master volume,
level and gain controls are all the way down.
2. Connect the outputs from the mixing console (or other
signal source) to the inputs of the SR8S, then connect
the high pass outputs from the subwoofer to the inputs
of the loudspeakers.
3. Make sure the subwoofer’s and loudspeaker’s gain
knobs are set to “U” (unity gain).
4. Push the line cord securely into the subwoofer’s /
loudspeaker’s IEC connectors and plug the other ends
into grounded AC outlets. The subwoofer/loudspeaker
may accept the appropriate voltage as indicated near
the IEC connector.
5. Break into your favorite dance routine.
6. Turn the mixer (or other signal source) on.
7. Turn the subwoofer on.
8. Turn the loudspeakers on.
9. Start the signal source and raise the mixer’s main
L/R fader up to a comfortably loud listening level.
There’s an illustration of a microscope,
so, of course, you’re going to get more
detailed information when you see this little
guy. There are explanations of features
and practical tips listed here.
It’s a good idea to pay attention to text displayed
next to a note icon, as this icon draws attention
to certain features and functions relating to the
usage of the SR8S.
Please write the serial numbers here for future reference
(i.e., insurance claims, tech support, return authorization,
make dad proud, etc.)

Things to Remember:
• Never listen to loud music for prolonged periods. Please see
the Safety Instructions on page 2 for information on hearing
protection.
• As a general guide, the mixer (or other signal source) should
be turned on first, SR8S subwoofer next, and loudspeakers
last. As such, the loudspeakers should also be turned o first,
followed by the SR8S, then the mixer. This will reduce
the possibility of any turn-on or turn-o thumps and other
noises generated by any upstream equipment from coming
out of the speakers.
• Save the shipping boxes and packing materials! You may
need them someday. Besides, the cats will love playing
in them and jumping out at you unexpectedly. Remember
to pretend like you are surprised!
• Save your sales receipt in a safe place.

In this example, a ProFX0v3 mixer is connected directly to an SR8S subwoofer which, in turn, is connected
to a pair of SRT22 loudspeakers. It is the perfect setup for a small club or... a totally happenin’ karaoke house party!
Simply connect the L/R outputs of a ProFX0v3 mixer directly to the A and B inputs of the SR8S subwoofer.
Then the High-Pass Outs of the subwoofer are connected to the channel inputs of a pair of SRT22 loudspeakers.
The gain knob on both should be set to Line. Here you will want to set the Speaker Mode to either Live or Club
and the Subwoofer HPF to SR8S Sub.

Perhaps you’re a DJ playing bumpin’ tunes in the middle of the night to a crowd that’s groovin’ and dancin’ to your fine
selection.
In this example, a laptop is connected to the inputs of two SR8S subwoofers.
The High-Pass Out of each subwoofer is then connected to the input of each SRT22 loudspeaker.
Additionally, a set of Mackie MC-450 headphones is connected to the phones jack of the laptop.
