D. The amplifier output is available on the SPEAKER+ and SPEAKER- terminals. The
maximum power is achievable with a 4 Ω loudspeaker only.
The higher the loudspeaker impedance, the lower the maximum power output; refer to
the table below:
Loudspeaker impedance
4 Ω (min)
8 Ω
16 Ω
32 Ω
64 Ω
Caution
Never connect a loudspeaker with impedance lower than 4 Ω to avoid
system damage.
Never exceed the maximum power output designated for the
loudspeaker to avoid loudspeaker destruction. Choose a loudspeaker
with proper impedance and maximum power values, or limit the
maximum volume level in the device configuration.
Use an external power supply to maximise the power output. Make sure
that the maximum Master volume value is +6 dB in the Hardware / Audio
menu if you use PoE and 4 Ω speaker.
