I've had a pretty eye opening day when it comes to these 1176's :shock:
OK... I like the 3.7k mod to match the Originals gain BUT my biggest issue with BOTH of mine (1xIC & 1xTranny input) is the threashold...
OK, I know about the MOD but I wanted to check things out for myself. So I did some research & found (in the UREI 1176 Manual) the threashold levels that the 1176 is suppossed to start compressing at:
20:1 = -24dB
12:1 = -25dB
8:1 = -26dB
4:1 = -30dB
Well, after I made absolutly sure my unit was properly calibrated, I injected these voltages into the input & it was DEAD ON RIGHT :!: :!: :!:
((Measured @ the 10k POT's wiper))
But DAMN... these are some LOW LEVELS
It just doesn't make sense... no wonder I feel a loss of headroom.
-30dB = 0.024 Volt RMS / 0.069 PP Volts
... those levels are down there... WTF. None of my meters even go that low. I even tested my DISTRESSORS & they didn't kick in until
close to 0dB (or just under depending on the Ratio)
My point is, when I put a mic pre in front, putting out .775 to 1v (or so)... it just KILLS the 1176 threashold level.
But damn, it's just like the manual said :sad:
I should be getting my Purple KIT in this week so we'll see if I'm crazy or not? (when it comes to the threashold, NOT the input level)
Thanks everyone for your input :thumb:
-----------------------------
How does changing the input tranny to 2:1 affect the impedence &/or the 12k loading resistors :?:
matthias - you had mentioned it didn't work our so well... could you give more details WHY?
Thanks
