RCA Pin Jack
(1) Sensitivity is the lowest level that will produce a full power output, or the nominal output level when the unit is set to
maximum gain.
(2) XLR-type connectors are balanced; Phone Jacks and RCA Pin Jacks are unbalanced.
(3) In these specifications, when dB represents a specific voltage, 0 dB Is referenced to 0.775 Vrms.
