Need help with Rolls Headphone Amp Modification

Archived from groups: rec.audio.pro (More info?)

Hi all,

I have my Rolls RA62 set up with the six aux sends of my board going
into the "insert" jacks so I can give each performer their own
headphone mix. I would like to be able to, with a single switch if
possible, bypass the inserts and go back to a single stereo mix.

Plugging an input into the "insert" jack disconnects that channel from
the L/R input. If I plug a dummy plug into the "insert" jack I can
place a jumper between the L/R signal path (capacitor C13 or C16) and
the jack to restore audio. However, I don't think this would disable
any audio entering through the "insert" jack.

There is a schematic at: http://www.rolls.com/data/ra62bman.pdf

Any advice would be greatly appreciated.

Thanks,

Mark.
