I would like to activate my SU 800 Commander with a sound trigger to remotely fire two SB 600 flashes. My camera is a D7000.
I have tried mounting the SU800 on an off camera Hot Shoe adapter and connecting the sound trigger to that, without success.
I can get the SB 800 to fire if the sound trigger is connected directly to it but a second SB 800 would require extra sync cords, which I would prefer not to use.
I have no problems using the SU 800 in the conventional way.
Any suggestions please?
