J99 gain is very hot

[cwalcott]

i just tried out the J99's on a drum tracking session. i'm using a pair for overheads. the drummer played an average level. not hitting too hard on anything. the J99's are very hot. i can't turn them up passed 2 without it clipping the input it's going into (directly into a MOTU 1224.)

i recall in the testing part phase of the building process that r28 and r32 (if i recall correctly) set the voltage going to the opamps. i believe i set them to a couple points below the recommended value. should i lower this again to give myself more headroom?

btw - these things sound amazing.

Verify the gain trim pots are 1K and not 10K. Also make sure the input transformer is jumpered for a 2:5 ratio, not 1:5.

i have it out now and man looking at the j1 and j2 jumpers. how are they supposed to be set for a 2:5 setting?

with the connectors facing away from me i have a jumper between j1 and j2 on the left side. and a jumper on j5.

figured it out. there was another post that shows the correct setting. the mics i use for these have a -10db pad so i'll start using those from now on.
