Input
|
|
|
Type Differential, electronically balanced
Impedance 10 kΩ 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 12 dB
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.
