VU Meter stereo attenuator

[skidmorebay]

I would like to add a stereo attenuator to a set of VU meters I have. I'm inspired by Crookwood's beautiful VU meter package, which has a single attenuator with 0db, -3db,-6db,-9db, etc. Six positions going down to -15db
Is the best approach an H-pad on a four-deck, 6 position Grayhill switch? Is there a good reference for the resistor values for each step? I've found one for 600 ohm equipment, but I'm not sure with that's the best approach for the line level output of a DAC.
Thanks!

maybe this? I think there are others mentioned here somewhere..

Right.... Others will have to chime in..
I built a 5k bridged T and have no issues apart from goofing my lower steps to go from off to more loud than I would initially like....

Check out the goldpoint site, they have schematics and good info. (And very high quality switches).
I ran a passive monitor controller with a 10k attenuator for years until I switched to an active design recently. With added features the passive interacted poorly with one of my monitors, which were tube 600 ohm input.

Somewhere here in the last 2 years I posted a Neve chart for VU attenuator values, which assumes you're not buffering and doing it the traditional resistive way. Can't find it.....
