NO SOUND, BUT THE GREEN LED IS RESPONDING
The green LED indicates the amp is producing a signal, so sound should be heard if the speaker is connected.
Check the speaker connections at both ends, and try a different speaker.
NO SOUND, RED LED ON
The amp mutes briefly when turned on and off to prevent thumps. If the amp overheats severely, it will mute until it
cools off. The fan will be running at full speed, and sound should resume in less than a minute. If the amp feels hot
and the fan is not running, it needs to be serviced.
BACKGROUND HUM
Balanced XLR or TRS cables are better for long runs.
