What causes amplifier overheating in Adastra CM30B?
If your Adastra Recording Equipment amplifier is overheating, make sure the cooling vents are free from obstructions. Verify that 8Ω speakers are not connected to the 100V terminals, and that the total 100V speaker wattage is less than the amplifier's rating. Ensure that you're not connecting both 100V and 8Ω speakers simultaneously and that the total load connected to the 8Ω output is not less than 8Ω.
What to do if USB player will not play audio from media on Adastra CM30B Recording Equipment?
