Michael Wynne Posted June 28, 2016 Report Share Posted June 28, 2016 For those of you using the BST75 from your Comteks, how many of you are using "1/4 " TRS input Versus XLR " Reason I ask with proper gain staging sending line level to the unit it always sounds a tad blown out. Is this as simple as an impedance mismatch ? I have a XLR to 1/4 inch impedance changer ( low to high ) on the way to me now to see if it makes a difference. It's subtle but driving me crazy.

Philip Perkins Posted June 29, 2016 Report Share Posted June 29, 2016 Blown out even if you reduce the input level with the gain pot? I've hit mine with +4 levels low imp signals for years.... Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted June 29, 2016 Report Share Posted June 29, 2016 Impedance is determined by the input circuitry, not the type of connector used. Seldom is feeding a low impedance output into a high impedance input the cause of overloading the input -- high impedance output into a low impedance input can overload the output.

Yes, I"m also sending a +4 line level signal out of a 788T, In order to achieve any kind of somewhat acceptable head room I have to trim back the BST 75 where I only occasionally see the meters light up. 34 minutes ago, John Blankenship said: Impedance is determined by the input circuitry, not the type of connector used.

I did indeed try a Low Z to High Z converter yesterday and it simply boosted the level into the Base station. Quote Link to comment Share on other sites More sharing options...
