TC BQ500 head fan query

Recommended Posts

I just received a second hand BQ500 head. No chance of trying it at stage volume at the moment.  The fan doesnt come in when cold. is this right? My Ashdown one is on all the time.

Ok, just tried switching on mine. Plugged in. Switched on. Green light comes on at the front. A VERY low electronic hum can be heard with my ear right on the casing. But the fan is definitely NOT running. Left it plugged in for half an hour. Still no sound of the fan running. Does that help?

If the fan is temperature controlled it won't come on until the heatsinks get up to a certain temperature to trigger the fan.
