Hi

i want to use the STA350BW amplifier but i am not quite sure which power supply i must use.
The first page of the Datasheet says:

Four power output configurations(a)
– 2 channels of ternary PWM (stereo mode)
(2 x 50 W into 6 Ω at 25 V)
– 3 channels - left, right using binary and LFE
using ternary PWM (2.1 mode) (2 x 18 W +
1 x 40W into 2 x 4 Ω, 1 x 8 Ω at 25 V)
– 2 channels of ternary PWM (2 x 50 W) +
stereo lineout ternary
– 1 channel of ternary PWM as mono-

The specifications page says:


Continuous output power, BTL, ternary mode
THD = 1% 27 W
THD = 10% 36 W
Continuous output power SE, binary mode, RL = 4 Ω
THD = 1% 12 W
THD = 10% 15.5 W


What kind of power supply will be sufficient?
Do i need something around 50 W with peak power over 100 W
or must i go up to 100 W continuous power with more peak?

Is the info from the first page related to music power or something similar?

thx
