Differential, electronically balanced
±15 V DC, clamped to earth for voltage transient protection
Female XLR input and male XLR loop output
10 kΩ differential between pins 2 and 3
Pin 1: Chassis/earth through 220 kΩ, 1000pF,
15V clamp network to provide virtual ground lift at audio frequencies;
Pin 2: Signal +
Pin 3: Signal -
Case: Earth ground and chassis
Differential DC blocking up to max. common mode voltage
>50 dB; typically 80 dB (50 Hz - 500 Hz)
Common mode: 425 kHz low-pass; Differential mode: 142 kHz
Integral to signal processing (<80 kHz)
0 dBV (1 V rms, 1.4 V pk). 0 dBV continuous average is typically the onset of limiting for
pink noise and music.
Audio source must be capable of producing a minimum of 20 dBV (10 V rms, 14 V pk)
into 600 Ω in order to produce maximum peak SPL over the operating bandwidth of the
loudspeaker.
Two-channel complementary MOSFET output stages class AB/bridged
350 W total
Note: Amplifier wattage rating is based on the maximum unclipped burst sine-wave rms
voltage the amplifier will produce in to the nominal load impedance low and high channels
30 V rms (42 V pk) into load impedance.
