22.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 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:

Introduction
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.
How to Use This Manual:
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.
Getting Started
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.
Please write your serial number 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, 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.

SRMv3 loudspeakers are the perfect tool for singer-songwriters touring the local coffee shops. Bring your favorite axe and mic, SRMv3 loudspeakers and cables and power cords.
In this example, a dynamic microphone is connected to the channel 1 input of an SRM350v3 loudspeaker, used for monitoring purposes. Be sure that the gain knob is set to “mic” in order to get an extra boost for the mic. If anything other than a microphone is attached to a channel input, make sure the gain knob is set to anything other than “mic” [“line” is a safe bet]. From there, adjust the gain as described on page 10.
Now grab your axe and plug it directly into the channel 2 input. Or if you use effects, connect the guitar to the effects input and another cable from the effects output to the channel 2 input. Set the channel two gain knob to “line”.
An SRM450v3 loudspeaker will be used for the main PA. Simply connect a cable from the SRM350v3 loudspeaker’s THRU jack to the SRM450v3 loudspeaker’s channel 1 input [gain knob set to “line”]. Also, make sure the Ch 1/Mix switch is down on the main SRM350v3, as well, so a mix of the vocals and guitar is relayed to the PA.
For the output, you will want to set a speaker mode, described in detail on page 11. For this type of setup, PA works well for the main SRM450v3. However, don’t count out the soloist mode! It has a nice low cut and a brilliant high end. Select the monitor mode for the SRM350v3 monitor. Lastly, you can ring out before you play, utilizing the SRMv3’s feedback destroyer [page 11] or just let it kill the feedback while playing.

In this example, an SRM1850 subwoofer and additional SRM450v3 loudspeaker have been added to the mix, giving our sound system some extra beef. It is a perfect setup for a small club.
Here, the L/R outputs of a ProFX8 mixer are connected directly to the channel A and B inputs of a single SRM1850 subwoofer. Set the gain to “U”.
The channel A and B high pass outputs of the SRM1850 subwoofer are connected directly to the channel 1 inputs of each SRM450v3 loudspeaker. Be sure that the gain knob on each is set to “line”. Select the VAR high pass mode on the SRM1850 and turn the adjacent knob to120 Hz for a matched system.
SRMv3 loudspeakers are also perfect for use as stage monitors. Simply connect a cable from each aux send to the channel 1 input of each SRMv3 loudspeaker used as a monitor. It’s a good idea to use the Feedback Destroyer here.
For the output, you will want to set a speaker mode, described in detail on page 11. For this type
of setup, we recommend selecting the PA speaker mode for live sound on your SRMv3 loudspeakers. If using any SRMv3 loudspeakers as monitors, select the monitor speaker mode.

SRMv3 loudspeakers may be daisy-chained via the male XLR connector labeled “THRU”. Simply plug the signal source (i.e., mixer output) into the input jack(s), and patch that loudspeaker’s THRU jack to the next loudspeaker’s input jack, and so on, daisy-chaining multiple SRMv3 loudspeakers. Make sure that the Ch 1 / Mix button is OUT [Ch 1]. See above for visual representations of daisy-chaining.

Here’s how to set up a large club system. In this example, the L/R outputs of a DL1608 mixer are connected directly to the channel A inputs of two SRM1850 subwoofers. The channel A full range outputs of these two SRM1850 subwoofers are connected directly to the channel A inputs of another
set of SRM1850 subwoofers. Talk about beefy low end...and we’ve only connected the subs!
The channel A high pass outputs of the last two SRM1850 subwoofers are connected directly to the channel 1 inputs of the main pair of SRM450v3 loudspeakers. Be sure that the gain knob on each
is set to “line”. Select the VAR high pass mode on the SRM1850 and turn the adjacent knob to120 Hz for a matched system.
SRMv3 loudspeakers are also perfect for using as stage monitors. Simply connect a cable from an aux send to the channel 1 input of an SRM350v3 loudspeaker. Here you will want to set a speaker mode, described in detail on page 11. Since these are monitors, select the appropriately named monitor speaker mode.
Select PA speaker mode for the main loudspeakers. You may also turn the feedback eliminator ON on all four SRMv3 loudspeakers, if desired.
