Low
impedance models can deliver up to 16/32W
rms
into a single 4Ω speaker by connecting the speaker to
either output and positioning the switch to the 8Ω position. The amplifier will not drive an 8Ω speaker above
8/20W
rms
. Connecting two 4Ω speakers with the switch set to 8Ω may result in a power disruption at the PoE+
port.
