Why my Bluetooth cannot connect to Adastra Amplifier?
If your Bluetooth device isn't connecting to the Adastra Amplifier, first ensure that Bluetooth is enabled on the sending device and that it is within 5-10m range. Also, check that “adastra” is the connected device. If there are multiple “adastra” devices, check each in turn or rename the device on the sending device.
What to do if Adastra RM244V output is very loud or distorted?
If the output from your Adastra Amplifier is too loud or distorted, first check that the level of the input signal isn't too high. You can also reduce the Mic/Line, Aux, Media, and/or Master level. Additionally, ensure the Mic/Line DIP switch setting is correct for the input type (Mic or Line).
How to fix no power LED on Adastra Amplifier?
If the power LED on the Adastra Amplifier control panel isn't lit, ensure the IEC lead is in good condition and properly connected. Also, make sure the POWER switch is on and check the mains inlet fuse.
Why is my Adastra RM244V overheating?
If your Adastra Amplifier is overheating, make sure the cooling vents are free from dust and debris. Also, ensure that 4Ω or 8Ω speakers are not connected to the 100V terminals and that the total 100V speaker wattage is lower than the amplifier's rating.
What to do if Adastra RM244V output is working but at very low level?
If the output from your Adastra Amplifier is working but at a very low level, verify that the input audio source level isn't too low. You can increase the MIC, LINE IN, USB/SD, and/or Master level. Check the output level setting on any Bluetooth connected device and verify the recording level of media files on USB. Also, ensure the Mic/Line DIP switch setting matches the input type and that the Mic/Line 1 muting level isn't suppressing audio playback.
Why is there no audio from Bluetooth device on Adastra Amplifier?
If there's no audio from your Bluetooth device connected to the Adastra Amplifier, ensure that the volume controls are not turned down on the sending device. Also, check the volume and Play/Pause buttons in case Bluetooth is muted.
What to do if Adastra RM244V Amplifier's power LED is on but no other LEDs and no output?
If the power LED is on but there are no other LEDs and no output from your Adastra Amplifier, check the input signals and the condition of the input connection leads. Also, ensure the Master, Mic/Line, Aux, or Media level controls are turned up.
How to fix USB/SD player if it will not play audio from media on Adastra RM244V Amplifier?
If the USB/SD player on your Adastra Amplifier won't play audio, press PLAY on the transport controls. Check that the memory device is properly connected by removing and re-inserting it. Ensure that the files are standard compressed digital audio files and that the memory device works on a PC or Mac for standard playback.
What to do if Adastra RM244V Amplifier's power light and output LEDs lighting but no output?
If the power light and output LEDs are lighting but there's no output from your Adastra Amplifier, check that the speaker output terminals are connected correctly. Also, check that the speakers are working by testing them on another amplifier if available.
How to stop feedback from microphone on Adastra Amplifier?
To reduce feedback from the microphone when using the Adastra Amplifier, face the microphone away from speakers and monitors. Additionally, turn down the Mic/Line and/or Master level.
