Output Stage
Maximum output power per channel @ 2 Ω
Maximum output power per channel @ 4 Ω
Maximum output power per channel @ 8 Ω
Maximum output power @ 4 Ω Bridged
Maximum output power @ 8 Ω Bridged
Maximum output power @ Hi-Z, 70 V distributed line
Maximum output power @ Hi-Z, 100 V distributed line
Peak total output, all channels driven
Maximum unclipped output voltage (Lo-Z)
Maximum output current (Lo-Z)
The power figure is calculated by driving and loading symmetrically all the
channels: uneven loads allow to achieve highest performance.
