The most widely used portable speakers ever;  

the all-new SRM450 and SRM350 deliver the  
unparalleled ease-of-use, professional sound quality  
and indestructible portability that made SRM a live
sound legend. Now packed with 1000W of power, the
widest selection of truly useful sound-enhancing DSP
and setup-friendly audio tools, SRM is ready for your
high-output application.

SRMs feature modern tools like application-specific

speaker modes and an automatic feedback destroyer,  
each with a single-button interface that gets you  
optimized performance in just seconds. And with  
the integrated 2-channel mixer, you can easily mix
multiple sources.

Only SRMs deliver this level of power and sound  

quality in such an indestructible, portable package.

After this introduction, a getting started guide  

will help you get things set up fast. The hookup  
diagrams show some typical setups, while the  
remaining sections provide details of the SRM350v3  
and SRM450v3 loudspeakers.

This icon marks information that is critically
important or unique to the loudspeakers.  
For your own good, read and remember them.

The following steps will help you set up the

loudspeakers quickly.

1. Make all initial connections with the power

switches OFF on all equipment. Make sure the master
volume, level, or gain controls are all the way down.

2. Connect the line-level outputs from the mixing  

console (or other signal source) to the inputs on the
rear panel of the SRM350v3 / SRM450v3 loudspeakers.

3. Make sure that the loudspeaker’s gain knobs are set

to (or near) “line”.

4. Connect the supplied AC power cords to the  

IEC sockets on the rear panel of each loudspeaker.
Plug the other end into an AC outlet properly configured
with the correct voltage as indicated below the IEC
socket.

5. Turn the mixer (or other signal source) on.

6. Turn the loudspeakers on.

7. Start the signal source and raise the mixer’s

main L/R fader up until audio may be heard
through the loudspeakers.

8. Adjust the master volume of the mixer to a

comfortably loud listening level.

9. Read the rest of this manual to learn how to set the

speaker mode and feedback destroyer to really dial in a
sound for the venue.

•  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, SRMv3 loudspeakers should

   be turned on last, after any mixer or other signal
   source. As such, they should also be turned off
   first. This will reduce the possibility of any turn-on
   or turn-off 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.
