As part of QSC’s ongoing commitment to product development, specifications are subject to change without notice.

2 hour rating using IEC60268 noise based on minimum impedance
Mid-band based on nominal impedance; 2.83 V at 1 m for 8Ω loudspeakers or 2 V at 1 m for 4Ω
Calculated as the nominal sensitivity plus 10× the log of continuous rated power in volts squared divided by nominal impedance
Calculated as the continuous calculated max output plus 6 dB
