Why is the Adastra DM25 output very loud or distorted?
If the output from your Adastra Amplifier is excessively loud or distorted, it may be due to a high input signal level. Try reducing the MIC, LINE IN, USB/SD, and/or MASTER level. Also, ensure that Hi-Z line level inputs are not connected via the MIC input.
What to do if Adastra DM25 overheating?
If your Adastra Amplifier is overheating, take the following steps: * Ensure the cooling vents are free from dust and debris. * Check that 4Ω or 8Ω speakers are not connected to 100V terminals. * Ensure the total 100V speaker wattage is lower than the amplifier's rating. * Make sure that 100V and 8Ω speakers are not connected simultaneously. * Verify that the total load connected to the 8Ω output is not less than 8Ω.
What to do if there is feedback from microphone on Adastra Amplifier?
If you are experiencing feedback from the microphone when using your Adastra Amplifier, try facing the microphone away from the speakers and monitors. Additionally, you can turn down the MIC and/or MASTER level to reduce the feedback.
What to do if Adastra Amplifier LED display is lit but no output?
If the LED display is lit on your Adastra Amplifier but there's no output, you should: * Check the input signals and the condition of the input connection leads. * Ensure the level controls are turned up. * Check the file type on USB or the connection via Bluetooth is OK. * Verify that the speaker output terminals are connected correctly. * Test the speakers on another amplifier, if available, to ensure they are working.
How to fix no output or LED display on Adastra Amplifier?
If your Adastra Amplifier has no output and the LED display is not lit, ensure the IEC lead is in good condition and connected properly. Check the mains inlet fuse and ensure the POWER switch is on.
Why is the output working but at very low level on Adastra Amplifier?
If the output on your Adastra Amplifier is working but at a very low level, check that the input audio source level is not too low. Increase the MIC, LINE IN, USB/SD, and/or MASTER level. Also, check for quiet recording of media files on the USB.
How to fix no connection via Bluetooth on Adastra DM25?
If you're experiencing connection issues via Bluetooth on your Adastra Amplifier, verify that the sending device is connected to the correct “MP3A” ID. Also, check the volume output level of the sending device.
What to do if USB player will not play audio from media on Adastra DM25?
If the USB player on your Adastra Amplifier will not play audio from media, press PLAY on the transport controls. Check that the memory device is connected properly by removing and re-inserting it. Ensure that you are using standard mp3 files. Verify the memory device works on a PC or Mac for standard playback.
