Maximum level .............................. +20 dBu (balanced, captive screw) or +4 dBV (unbalanced, RCA/TRS) at
1% THD+N
Input sensitivity
RCA and TRS inputs
......... -10 dBV (One input driven), -16dBV (Both inputs are summed)
Captive screw input .......... +4 dBu if driven by one input
-2 dBu if both inputs are summed
