Wiring
|
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 -
Case: Earth ground and chassis
|
Nominal Input Sensitivity
|
0 dBV (1 V rms) continuous is typically the onset of limiting for noise and music
|
Input Level
|
Audio source must be capable of producing a minimum of +20 dBV (10 V rms) into 600 Ω to produce maximum peak SPL over the operating bandwidth of the speaker
