    we have 5 small video viewing room in a row.  each is 5.1 audio.  Im doing a monitor control for them and would like to put the power amps in the same box.  the 5 speakers are 8 ohms, peak power is maybe 10 - 15 watts, average seems to measure around .9 watts per channel   the 3 mains have approx 18 feet of wire, the 2 surrounds are about 40 feet.  There are several video monitors,  computers and scopes in each room plus  the audio monitor control.  . I was thinking of going to the class D amp instead of the AB just for the lower heat.  But if RF is an issue I will stay with the Class AB..  it would be 30 of these amps in about 50 feet of hallway

    Hi,

    If long cable application, I suggest adding inductor and beads on output. It will be better for EMI performance.
