LED   Displays loudspeaker status

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.
