Troubleshooting
Power
Can’t turn on the Power Amplifier.
•Make sure that the power cord is properly plugged into the wall outlet (➔ 16).
•Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it in again.
The Power Amplifier turns off unexpectedly.
•When the set ASb starts running, the power amplifier will automatically go standby (➔ 21).
•If the power amplifier cannot start with the Standby LED blinking, then it may be problem with the power amplifier. If speaker cables touch the chassis, this may cause the power amplifier to short out and make sure the plus terminals of speaker cables do not touch the chassis or the minus terminals.
Please try the method below:
–Set the POWER switch to OFF and disconnect all speaker cables. Check that the top of the set (cooling vent) is not blocked. When the power amplifier has cooled down, reconnect all speaker cables and set the POWER switch to ON. Then Press ON/STANDBY.

Audio
There’s no sound.
•Make sure the speakers are connected correctly (➔ 15).
•Check all connections and correct as necessary (➔ 15).
•When making XLR IN input, make sure that the INPUT SELECT switch is switched to the XLR side.
•Make sure the correct input source is selected.
•Make sure the analog audio cable is connected correctly.
•Make sure that all audio connecting plugs are pushed in all the way.
The sound quality is not good.
•Make sure the speaker cables are connected with the correct polarity (➔ 15).
•Make sure all audio connecting plugs are pushed in all the way (➔ 15).
•The sound quality can be affected by strong magnetic fields, such as that from a TV. Try moving any such devices away from the power amplifier.
•If you have any devices that emit
•When making RCA IN input, make sure that the INPUT SELECT switch is switched to the RCA side.
•Check the connection in case of
Audio performance
•Audio performance will be at its best about 10 to 30 minutes after the power amplifier has been turned on and had time to warm up.
•Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality. So don’t do it.
External Components
The 12V trigger does not work.
• Make sure the cables are connected to the jacks firmly.
The power amplifier contains a microcomputer for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this should happen, unplug the power cord, wait at least 5 seconds, and then plug it again.
Before disconnecting the power cord from the wall outlet, set the main power switch to OFF.
If during idling the cover is too hot to touch, then ventilation needs to be improved.
