Question about Behringer Bx4500h Ultrabass 450w Bass Amplifier
How do i fix it
If the hum exists with NO input cable plugged in, this requires repair, most likely in a shop familiar with the unit.
The problem may be in the unit's power supply or a broken connection inside.
This problem can also happen if one of the oputput amp transistors shorts driving out DC current into the speaker which is a grave risk to the speaker. Check the DC out of the speaker connector. If it is NOT very near zero, say less than 0.1 volts DC, do NOT copnnect speakers..
