channels can work independently with their own volume control and, on the other
hand, the amplifier can be configured as a 3-channel amplifier (2.1), which
means 2 independent stereo / parallel channels and 2 combined channels for the
subwoofer in bridge mode.
As a 3-channel
amplifier, PA 1254 integrates crossover function with a low-pass filter for the
subwoofer and two high-pass filters with frequency adjustment.
