class TV). Thanks to the wide voltage range and
to the high out current capability it is able to sup-
ply the highest power into both 4 and 8 loads.
The built in muting function with turn on delay
simplifies the remote operation avoiding switching
on-off noises.
Parallel mode is made possible by connecting
more device through of pin11. High output power
can be delivered to very low impedance loads, so
optimizing the thermal dissipation of the system.
