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.
Connection of External Microphone
®
2N
IP Audio Kit is equipped with an input for connection of an external electret microphone on
the MIC+ and MIC- terminals. Shielding of the shielded cable is connected to the IN- terminal.
Caution
•
Undesired noise may be heard in the earphone where EMI affects the microphone
signal. To avoid this, connect the microphone using a shielded cable of the
minimum possible length.
•
If you use a one-conductor shielded wire, interconnect the MIC− and IN− terminals.
