Spectral DMC-30SL

Hi guys,

I had changed a spectral DMC30SL (G2 module) and DMA250,it was spectacular!..but i found the RCA input is higher gain than the Balanced input,i did check with the internal dip switch setting,they all the same(from input 1 to 6,no attenuator on),is that normal?..any one can help?

My associated equipment is DCS,both RCA and Balanced output is set to same output(2V).

Thank you.
