Troubleshooting
No Sound?
If you have your source and speakers connected with music playing but no sound is audible, check the following:
1.
Ensure none of your components are in ‘mute’
2. Verify that the power cord is plugged in and that the both the unit and outlet are powered on.
3. Check the front panel and make sure that the light bar is on.
4. If the light bar is o and there still isn’t any sound, put your ear next to the tweeter of your speaker and have someone
turn your amplifier off then on again at the rear switch. You should barely hear a click when the amplifier is turned on
and off
5. If you can hear the amplifier turn on and off, but there still isn’t any sound, make sure you are getting a signal to it.
6. Verify that the XLR/RCA switch is properly set.
7.
Try replacing the interconnects to verify the connection between the amplifier and source is sound.
8. Verify your interconnects are working by replacing them on a different set from a connection that you know works.
9. Now that you have interconnects that you know work, try connecting the amplifier to another source that you know
has worked in the past.
If you are still experiencing problems after checking all possibilities and using the resources provided please contact your
dealer or Wyred 4 Sound directly for further assistance.
Got Hum?
If you put your ear right next to the tweeter of your speaker, you should barely be able to hear any hiss from the amplifier in
normal conditions. If the noise is easily heard at a distance, try putting your source on mute, or pause. If this eliminates the
noise, it’s inherent in the source or preamplifier. If your preamplifier doesn’t disconnect the outputs when muted, and the
noise still exists while muted, try disconnecting the inputs to the amplifier. If the noise is still there when the inputs are
disconnected, and the inputs are shorted with shorting plugs, then your amplifier may need some servicing. If the noise is not
there when the inputs are disconnected, try putting a cheater plug (ground isolator) on one or all components in order to
eliminate a ground loop issue. NOTE: We only recommend using a ground isolator for troubleshooting purposes only, and
should be removed after the problem has been found. Having the ground of any unit disconnected can potentially create a
dangerous situation.
An easy way to locate a noisy component is to start disconnecting components one at a time, starting with your source
component. Digital cable boxes and satellite receivers are notorious for creating a ground loop hum. This is normally caused
by the potential difference on the input wire (shield side) for either of the boxes when referenced to ground. If this is the case
in your system, the installation of an isolating transformer would be the easiest solution and are normally readily available at
your local electronics parts store. A better solution is a power strip with grounded and surge protected F-connectors that you
can pass a signal through.
Amplifier Faults
If the SX-1000R faults, see section “Short Circuit/Over-Current Protection” above for possible reasons. Check the outputs
and speaker connections to make sure they aren’t shorted to each other or ground. If the amplifier faults while playing music
loud, it may mean you may need a more powerful amplifier for your tastes or system. If it faults without playing too loud,
your speakers may be too demanding and may require a higher wattage amplifier. Contact your dealer or Wyred 4 Sound for
further assistance.
