    M8mkIV lpad question

    Jon or Thomas, lhe lpad is the combo of 15 ohm and 12.5 ohm resistors. Which side is the shunt and which, the series?

    Thanks very much,
    Andy 8O

    The five 12.5 ohm resistors in parallel give the 2.5 ohms for the series leg (Ohms law, ya know!). The 15 ohm resistors were paralleled, then further reduced with the additional series connection across the shunt leg of two 5 ohm resistors(connected in series) in parallel with the 5-15 ohm resistors. The additional shunt network of the two 5 ohm resistors weren't "predicted" by the LSPCAD sim, but were part of the final voicing.

    Regards,

    Jon

    Note that the text in the article describes this connection- I had to double check against it, because the project is a couple of years old, and there's been a lot of stuff flowing through the "buffers" since then!

      Ohm who? 8O Thanks, Jon. That's what I thought and went ahead and did, but it's been so long since I took basic physics that I'd forgotten.

      Will hopefully be listening to my M8a's tomorrow night if all goes well.

      Will let you know my impressions.

      Best,
      Andy
