Hi Guys,
i am just about to build some in-line -20dB H-attenuators to pad down mic levels for some of my mic-pres, mounted in short XLRm-XLRf cables. I have all the relevent info to calculate the resistor values, but i am unsure whether to build -20dB H-pads at 200 Ohms or 600 Ohms, or at any other value for that matter, to give optimum performance. Mics in question are Shure SM57/8's,Sennheiser 421's,Yamaha MZ204/5's and Neumann U48's. ie no phantom required. Mic-pres include Helios, BBC/Glen, Audix, and my new home-made API312ish pre's with Neve (Marinaire/Belclere/Willesden) trafo's.
ANy help/suggestions would be greatly appreciated as ever,
All the best,
ANdyP
