Service Information
If you think your Martin Audio product has a problem, please check out the following troubleshooting tips to confirm the
problem. Visit the Support section of our website (www.Martin Audio.com) to contact our technical support team. You may find
the answer to the problem without having to return your Martin Audio DX0.5 for servicing.
Troubleshooting
No Power

Is it plugged in?

Make sure the power cord is securely seated in the IEC socket and plugged all the way into the AC outlet.

Is anything on the front panel illuminated? If not, make sure the AC outlet is live [check with a tester or lamp].

Make sure the rear panel power switch is in the ON position.

Are all the lights out in your local area? If so, contact the local power company to get power restored.

Is the fuse blown? See the following instructions for removing and replacing it.

If nothing is illuminated (and you are certain that the AC outlet is live and the fuse is not blown), it will be necessary
to have the DX0.5 serviced. There are no user serviceable parts. Refer to Repair on the next page to find out how to
proceed.
Noise / Hum

Try changing the position of the main ground lift switch [3] on the rear panel of the DX0.5.

Check the signal cables between the mixer and the processor and the processor, amps and loudspeakers. Disconnect
them one‐by‐one. If the noise goes away, you will know which input or output is causing the problem.

It often helps to plug all the audio equipment into the same AC circuit so they share a common ground.
To remove and replace the fuse:
1. Disconnect the power cord from the IEC socket.
2. Remove the fuse drawer by prying it open with a small screwdriver. It will slide all the way out.
3. Remove the fuse and replace it with an equivalent‐type fuse: T 800mAL / 250 V
4. Replace the fuse drawer by pushing it all the way back into the IEC socket.
If two fuses blow in a row, there is a more serious problem. Try a different outlet in a totally different location. If fuses continue
to blow, see the Repair section on the next page to find out what to do.
No Sound

Are the level controls on the mixer or amplifier turned all the way down? Follow the procedures in "Getting Started"
section on page 5 to verify that all of the volume controls in the system are properly adjusted.

Is the signal source working?

Are all the connections good and sound? Make sure all of the connecting cables are in good repair and securely
connected at both ends.
