Gryphon auto glow

[gashead]

I currently have 2 x Gryphon auto glow lite, in my N5C and N7, why is one of them making a buzzing noise when the plug is good and a normal straight tone when its gone bad, my other one just makes the same tone normal straight tone, but the plug is good, they also both light purple colour when plug good and not light if bad, i would like them both to operate the same but cannot for the lift of me work out what i dont differently.

ok figured it out, i use the end points and sub trim on the aux channel i use for the gryphon, i prefere it to be a solid tone when glow not detected and a buzzing tone when glow is working
