DIGITAL SYSTEM AMPLIFIER
34 Owner‘s Manual / Bedienungsanleitung
DSA 8410
Amplifier at rated conditions, all channels driven, rated loads, unless otherwise specified.
1) Output Mode 2 Ω (1000 W at 2 Ω, 500 W at 4 Ω, 250 W at 8 Ω)
2) Output Mode 4
Ω (1000 W at 4 Ω, 500 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 10
Ω
8) 200 V at 20 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
