Alrighty... is that trigger output on the 950 fused? I'm asking because I'm about to add a relay to trigger my sub amp and the relay draws supposedly 30ma but really 34ma is drawn... So, with the 5ma for the 755 and the 8ma for my 2-200's that's 47ma with nothing else going wrong...

I haven't plugged the new sub relay in yet... do you guys think I'm in danger of burning out the trigger output?

Specs for the 950 state the output trigger is good for 100mA, so triggering the relay should be fine and the relay should handle a lot more than the 100mA.

Ah.. the manual says 50ma, the specs sheet on the website says 100ma... hmm I guess I'll just assume the higher number
Manual:
Trigger Outputs 1, 2(Zone) Sequential Delay 50 mA @ 12 VDC

Specs:
Trigger Outputs (x2): 12 VDC, 100 mA maximum

You probably out to make sure the trigger is diode protected, or add a diode across the
relay coil to "bleed" the coil current thru the diode. You could blow the trigger output if something isn't shunting the coil current of the relay.

Perhaps they are both right? The manual could be saying that each trigger is 50mA while the specs are indicating that both together are 100ma (2 triggers X 50mA).
