Maximum output power: two-channel 50W / 4Ω + 50W / 4Ω, associated mono 100W / 2-3Ω,
Two-channel output power:
12V / 10 + 10W (8Ω) / 15 + 15W (4Ω);
15V / 13 + 13W (8Ω) / 25 + 25W (4Ω);
19V / 22 + 22W (8Ω) /> 39 + 39W (4Ω);
22-24V / 32 + 32W (8Ω) / 50 + 50W (4Ω);

Associated mono output power:
12V / 18W (4Ω) / 22W (3Ω) /30W (2Ω)
15V / 27W (4Ω) / 35W (3Ω) / 48W (2Ω)
19V / 45W (4Ω) / 55W (3Ω) / 75W (2Ω)
24V /70W (4Ω) / 95W (2-3Ω)

Note:
The output power is related to the power supply voltage, the speaker impedance and the source input. Usually higher power supply voltage, can support the output power will be larger. Different impedance horn, can support the output power is also different.
