A balanced T-pad (known as an H pad) has resistors in series with both sides of the input, and both sides of the output, but with a common resistor (R2) bridging the midpoints You can create your own pad using resistors. Here is one example:[[File:audiolevelmatchingpad.png]]A simple 2 resistor model can be used. Attenuation in dB = 20 * log10((R1 + R2) / R2)[[File:audiolevelmatchingpad2.png]]The L-pad is the classic voltage divider circuit using two resistors to reduce the input voltage by some amount.
