What to do if the MTX Amplifier power LED is on but there is no output?

If the power LED is on but there's no output from your MTX Amplifier, first, check if the volume on your source unit is turned down; if so, increase it. Next, ensure that all speaker connections are properly made. Also, verify that the gain control on the amplifier isn't set too low; if it is, turn it up. If you're using signal processing units, make sure they're powered on. Lastly, check your speakers; if they're all blown, replace them.
