Thanks to the wide voltage range and to the high
out current capability it is able to supply the high-
est power into both 4Ω and 8Ω loads even in pres-
ence of poor supply regulation, with high Supply
Voltage Rejection.
The built in muting function with turn on delay sim-
plifies the remote operation avoiding switching on-
off noises.
