Peavey DDT light

[Bluescout]

Does anyone know about the DDT light on my Firebass amp? I'm curious if the quality and rating of the attached speaker cab affects how soon the light comes on.

I believe the DDT light indicates that the amp's built in compression circuit is active. The circuit protects speakers from possibly damaging power spikes during operation.

 

If you're using speaker cabinets that are rated below the amp's recommended impedance rating (probably 2-4 ohms) then that would definitely cause the circuit to become active a whole lot sooner than usual.

 

However, if your cabs are above the recommended rating, then I doubt the quality of the cabs themselves would have anything to do with the circuit activating.

 

What kind of cabs are you using with this head (4 ohm, 8 ohm, how many, etc)?

Hope this helps!

I run an unknown 15 with an EV-15L, and an old Sonic 410 with probably 200 watt rating, both 8 ohm. It just seems that even with my low output yamaha, I'll leave my post volume up around 8 and can't get the pre-volume past maybe 4. I thought maybe the DDT could detect that the speakers were pushed past their limit.
