1)Output Mode 2 Ω (500 W at 2 Ω, 250 W at 4 Ω, 125 W at 8 Ω)

2)Output Mode 4 Ω (500 W at 4 Ω, 250 W at 8 Ω)

3)Output Mode 70 V

4)Output Mode 100 V

5)Depending on the ambient temperature, the unit might reduce the output power at 2 Ω load

6)50 Hz High Pass is automatically activated in 70 V / 100 V output mode

7)140 V at 20 Ω

8)200 V at 40 Ω

9)Due to the mains voltage situation in Japan the values for the maximum output power can be decreased by 15%

10)Depth of the unit without rack ears (detachable): 380 mm
