SRM350v3 and SRM450v3 Powered Loudspeakers

Appendix A: Service Information

Poor sound

•  Is it loud and distorted? Make sure that you’re not  

    overdriving a stage in the signal chain. Verify that  
    all level controls are set properly.

•  Is the input connector plugged completely into  

    the jack? Be sure all connections are secure.

Noise

•  What is the position of the gain knob? It should  

    be at (or near) “mic” when a mic is connected  
    and at (or near) “line” when a line-level signal  
    is connected. It should be “off” for all unused   
    inputs.

•  Make sure all connections to the active  

 

    loudspeakers are good and sound.

•  Make sure none of the signal cables are routed  

    near AC cables, power transformers, or other   
    EMI-inducing devices.

•  Is there a light dimmer or other SCR-based device  

    on the same AC circuit as the SRM loudspeaker?  
    Use an AC line filter or plug the loudspeaker into  
    a different AC circuit.

Hum

•  Try disconnecting the cable connected to the main  

    input jack. If the noise disappears, it could be  
    a “ground loop,” rather than a problem with the  
    SRMv3 loudspeaker. Try some of the following  
    troubleshooting ideas:

•  Use balanced connections throughout your system  

    for the best noise rejection.

•  Whenever possible, plug all the audio equipment’s  

    line cords into outlets which share a common  
    ground. The distance between the outlets and the  
    common ground should be as short as possible.

Repair

For warranty service, refer to the warranty  

information on page 23.

Non-warranty service is available at a factory- 

authorized service center. To locate the nearest  
service center, visit www.720trees.com, click “Contact 
Tech Support” and select “Locate a Service Center  
or Distributor” [3]. Service for SRMv3 loudspeakers  
living outside the United States can be obtained  
through local dealers or distributors.

If you do not have access to our website, you may call 

the Tech Support department at 1-800-898-3211,  
Monday-Friday, during normal business hours, Pacific 
Time, to explain the problem. Tech Support will tell you 
where the nearest factory-authorized service center is 
located in your area.

If you think the SRMv3 loudspeaker has a problem, 

please check out the following troubleshooting tips and 
do your best to confirm the problem. Visit the Support 
section of our website (www.720trees.com) where you 
will find lots of useful information such as FAQs and 
other documentation. You may find the answer to the 
problem without having to part with your loudspeaker.

Troubleshooting

No power

•  Our favorite question: Is it plugged in? Make sure  

    the AC outlet is live [check with a tester or lamp].

•  Our next favorite question: Is the power switch  

    on? If not, try turning it on.

•  Is the LED on the front panel illuminated?  

    If not, make sure the AC outlet is live.  
    If so, refer to “No sound” below.

•  The internal AC line fuse may be blown. This is  

    not a user serviceable part. If you suspect the  
    AC line fuse is blown, please see the "Repair"   
    section next.

No sound

•  Is the input gain knob for the input source    

    turned all the way down? Verify that all the gain  
    knobs in the system are properly adjusted. Look  
    at the level meter to ensure that the mixer is   
    receiving a signal.

•  Is the signal source working? Make sure the    

    connecting cables are in good repair and securely  
    connected at both ends. Make sure the output  
    level control on the mixing console is turned up  
    sufficiently to drive the inputs of the  speaker.

•  Make sure the mixer does not have a mute on or a  

    processor loop engaged. If you find something like  
    this, make sure the level is turned down before  
    disengaging the offending switch.

•  Has it shut down? Make sure there is at least   

    six inches of free space behind each SRMv3    
    loudspeaker.

Poor bass performance

•  Check the polarity of the connections between the  

    mixer and the loudspeakers. You may have your  
    positive and negative connections reversed at one  
    end of one cable, causing one loudspeaker to be  
    out-of-phase with the other.

•  Poor bass performance may be the result of bad  

    AC power. See the section titled ‘AC Power’ on  
    page 12 for further details.
