|
|
Type Differential, electronically balanced
Impedance 10 k& OMEGA; Balanced (AC Impedance)
Nominal Input Sensitivity -2.5 dBV (0.25 V rms, 1.00 V peak) continuous average is typically
the onset of limiting for noise and music
Where pink noise has 12dB Peak to RMS ratio
Audio Input Source Audio source must be capable of producing +16 dBV (6.3 V rms, 9.0 V
peak) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker with a sine wave.
