Anybody here know how to make audio pads? -20dB, -50dB etc. I need to make some with XLR cables too attenuate mic level signal. Thanks
Hello, You can use either PI ot T attanuators for this: http://chemandy.com/calculators/pi-attenuator-calculator.htm http://chemandy.com/calculators/t-attenuator-calculator.htm More calculators like that can be found on this page: http://chemandy.com/calculators/calculator-index.htm Bertus
Great thanks for the websites. Do you know which pins of the XLR gets the resistors for the T pad? I assume pin1 R1 pin2 pin1 R1 pin3 ??? shunt ???
Hello, If the signal is balanced you will need an H or O attenuator. Here is an example for T and H: http://www.csgnetwork.com/decibelattenuatecalc.html Bertus
Hello, With the given calculator you can create the attenuation pad needed. What you need to know is the input impedance, output impedance and attenuation. For example input 600 Ω, output 10 kΩ, 20 dB will give you the following circuit: This page from the wiki shows you some theory behind the attenuation pads: http://en.wikipedia.org/wiki/Attenuator_(electronics) Bertus
I finally found the pinout http://www.uneeda-audio.com/pads/ At the bottom of the page Thanks guys for the replies!!!
