for real-world working musicians, DJs, events, venues,
and beyond.
The latest acoustic processing technology, powerful
amplifiers, and the ultra-versatile SRT Mix Control™ means
easy setup, incredible sound, and unbeatable reliability.
Built-Like-A-Tank™ construction features rugged molded
cabinets and tough steel grilles that are built to last.
As the larger gigs come rolling in, your audience gets
bigger, and your needs demand better sound and flexibility,
SRT is YOUR Next Big Thing.
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 SRT loudspeaker setups, including some that
involve the SR8S subwoofer.
This icon marks information that is critically
important or unique! For your own good, read and
remember them...it is a good idea to pay special
SRT Professional Powered Loudspeaker Series
attention to these areas in the Owner’s Manual
marked with the “VERY IMPORTANT” hand icon.
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.
. 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. If not using a subwoofer, connect the outputs from
the mixing console (or other signal source) to the inputs
on the rear panel of the loudspeakers.
3. If using a subwoofer, connect the outputs from
the mixing console (or other signal source) to the inputs
on the subwoofer, then connect the high pass outputs
from the subwoofer to the inputs of the loudspeakers.
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. Turn the mixer (or other signal source) on.
6. Turn the subwoofer on (if applicable).
7. Turn the loudspeakers on.
8. Make sure the loudspeaker’s channel gain knob(s)
are set to mic / Hi-Z or line followed by setting the channel
levels to (or near) 0 dB. More information may be found
on pages -3.
9. Start the signal source and raise the mixer’s main L/R
fader up to a comfortably loud listening level.
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 SRT Series.
The following steps will help you set up the loudspeakers
quickly.
Please write the serial numbers here for future reference
(i.e., insurance claims, tech support, return authorization,
make dad proud, etc.)

Date of purchase:
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, subwoofers next, and SRT loudspeakers
last. As such, the SRT loudspeakers should also be turned
o first, followed by the subwoofers, 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.

SRT loudspeakers are the perfect tool for singer-songwriters touring the local coee shops. Bring your favorite axe and mic,
SRT loudspeakers and cables and power cords.
In this example, a Mackie EM-9C condenser microphone is connected to the channel input of an SRT25 loudspeaker,
used for monitoring purposes. Note that the gain knob is set to Mic.
Now grab your axe and plug it directly into the channel 2 input. Or if you use eects, connect the guitar to the eects
input and another cable from the eects output to the channel 2 input. Note that the gain knob is set to Hi-Z.
An SRT20 loudspeaker will be used for the main PA. Simply connect a cable from the SRT25 monitor’s MIX OUT jack
to the SRT20 PA’s channel input.
For the output, you will want to set a speaker mode, described in detail on page 4. For this type of setup, Live works well
for the main SRT20. Select the Monitor mode for the SRT25 monitor. Additionally, you will want to set the monitor’s
configuration. The Mic setting is fine for the channel input, but the channel 2 input should be set to Hi-Z to account
for the guitar.

Here’s how to set up a large club system. In this example, the L/R outputs of a DL6S mixer are connected directly
to the channel inputs of a pair of DRM8S subwoofers. The Direct Out of each subwoofer is then connected to the inputs
of an additional pair of DRM8S subwoofers.
From here, the high-pass outputs of the two outer DRM8S subwoofers are connected directly to the inputs of a set
of SRT25 loudspeakers. The Speaker Modes of these PA loudspeakers may be set to Live (or Club) and the Subwoofer
HPF set to DRM Sub. Talk about beefy low end!
Outputs and 2 from the mixer may be used as aux sends; these are connected directly to the channel inputs of a pair
of SRT25 loudspeakers to be used as monitors for the band. The gain knob on all SRT25 loudspeakers in this example
should be set to Line. The Speaker Modes of the monitor loudspeakers may be set to Monitor.

In addition to accepting a balanced mic signal
using an XLR connector, these input channels may
also accept /4" line-level signals driven by balanced
or unbalanced sources.
Channel 2 may also accept a Hi-Z source (such
as a guitar) via the /4" input without the need for
a separate DI box. Be sure to set the Ch. 2 In to Hi-Z in
the Configuration menu, though! Directions on page 8.
To connect balanced lines to these inputs, use
a /4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands
for Tip-Ring-Sleeve, the three connection points
available on a stereo /4" or balanced phone jack
or plug. TRS jacks and plugs are used for balanced

4. Gain [Ch. and 2]
The gain knobs adjust the input sensitivity
of the mic/line inputs. This allows signals from
the outside world to be adjusted to run through
each channel at optimal internal operating levels.
It ranges from o (knob fully down) up to max (knob
fully up).
If connecting mixer outputs to loudspeaker
inputs, set the gain knob to 9:00 [“LINE”]
for optimal sound and performance.
6. /8" Input [Ch. 3/4]
This input may accept a stereo /8" line-level signal
from a phone, tablet, MP3 player, or other signal
source.
NEVER connect the output of an amplifier
directly to an SRT input jack. This could
damage the input circuitry!
7. Gain [Ch. 3/4]
This gain knob adjusts the input sensitivity
of the /8" stereo input. This allows signals from
the outside world to be adjusted to run at optimal
internal operating levels. It ranges from o (knob
