|
Wiring4 |
Pin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies Pin 2: Signal + Pin 3: Signal – Pin 4: RMS Pin 5: RMS
Case: Earth ground and chassis |
|
Nominal Input Sensitivity |
0 dBV (1.0 V rms) continuous is typically the onset of limiting for noise and music |
|
Input Level |
Audio source must be capable of producing of +20 dBV (10 V rms) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker. |
