30 db pad? H pad....?

I am working on a WardBeck 402 EQ, and its output is really hot. Jim from Matrix suggested a 30db H pad. I used the search, but could not find any info on it. Can someone describe the connections, or post a schematic?

Jensen has a 20db pad they use for mic inputs, is this simular?

Thanks

Peace,

An H-pad is a balanced version of a T-pad. For instance, if you used this calculator:
http://www.microwaves101.com/encyclopedia/calcattenuator.cfm
...you'd divide R1 by two and place one half in each leg. R2 remains the same.

Also, here's a calculator that'll give you the H-pad values directly:

A mic pad is different; a "U" pad (balanced L) is usually used because of the asymmetrical impedances (high-ish input impedance, low output impedance).

The gain of that eq is 38db if I recall.

Thanks for the info. I am a little confused on some numbers. The H pad refers to input ohms, and output ohms and ends up using 5 resistors. Is this to change the impediance of the line?

I guess what I think I have is 38db output at 600 ohms (I would have to check again). IF that is true it appears that I would use a 232 ohm resistor in series with the output of the module. Then a 38 ohm resistor bridging the two 232 ohm resistors. That would be followed by another pair of 232 ohm resistors in series like the first ones.

----232----|-----232----

38

----232----|-----232----

I guess this keeps the input of the attenuator and the output of the attenuator a constant 600 ohms. (I will have to check to see if that is what the impedience really is)

Did I get that right?
