below to avoid equipment damage or electrical injury:
Connect the microphone, loudspeaker, headset or external amplifier.
Connect the digital input and output.
Connect the UTP cable.
Connect a 12V power supply (unless PoE is used).
Loudspeaker Connection
2N SIP
®ConverterAudio is equipped with a power amplifier for 1 or 2 loudspeakers.
The loudspeakers to be used must have the nominal impedance of 4–8 Ω each. Refer
to the table below for possible configurations and related maximum power outputs
(sinus, THD < 1 %):
Loudspeaker(s) 12 V / 2 A PoE
Two 4 Ω 2× 10 W 2× 5 W
Two 8 Ω 2× 9 W 2× 5 W

Caution
Be sure to connect the power supply as the 2N SIP

last step. The same applies to PoE supply from the LAN.
Caution
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 4Ω speaker.

Figure: Digital Input Connection
LAN Connection
2N SIP
®ConverterAudio can be connected to a standard local area network using a
LAN interface via the RJ-45 connector on the back panel. Always use CAT-5d or higher
class cables for reliability reasons.
Warning
Do not exceed the upper voltage and current limits to avoid irreversible
damage of the equipment.
Warning
When you connect a device containing a coil, such as a relay or an
electromagnetic lock, it is necessary to protect the intercom against voltage
peak while switching off the induction load. For this way of protection we
recommend a diode 1A / 1000V (e.g., 1N4007, 1N5407, 1N5408) connected
antiparallel to the device.

through active network elements or injectors meeting the IEEE 802.3af standard.
Power Supply Connection
2N SIP
®ConverterAudio can be fed using active network elements or PoE injectors
via the LAN interface. In case this option is unavailable, use a 12V DC/2A (Part No.
914102E) power supply or another power supply on condition that you keep the
nominal values included in the Mechanical and Electrical Parameters subsection.
Connect the 12V DC power supply either to the back panel supply connector marked
, or terminals marked and .DC IN DC IN + DC IN –

Note
With PoE, the integrated amplifier power output is limited to 10 W. To
utilise the maximum power output of the amplifier, feed 2N SIP
