Nominal Input Sensitivity

10 dBV (3.2 V rms, 4.5 V peak) continuous is typically the onset of limiting for noise and music

Input Level

Audio source must be capable of producing +20 dBV (10 V rms, 14 V peak) into 600

to pro-

duce the maximum peak SPL over the operating bandwidth of the loudspeaker

Type
