Q:
When calibrating my 888/24 and 888 I/O interfaces, I am getting the 888/24 to output a 1.23V signal but the 888 I/O will only output a 1.16V signal. (-20dB reference level). Both interfaces are functioning at +4dBu
 
A:
This observation represents normal operational difference between the two interfaces. Both the 888/24 and original 888 are factory calibrated for 18dB of headroom. However, the 888/24 can be adjusted for more than 20dB of headroom but the original 888 can't.
