It is very easy to connect
avoid equipment damage or electrical injury:
1. Connect a loudspeaker, headphones or an external amplifier.
2. Connect the digital input and output.
3. Insert the MicroSD card.
4. Connect the UTP cable.
5. Connect a 12V power supply (unless PoE is used).

loudspeakers. The loudspeakers to be used must have the nominal impedance of
4–16Ohm. Possible configurations and related maximum power outputs (sinus, THD <
1%) are included in the table below:
Use the

N/O (normally open) or N/C (normally closed) mode.
Warning Do not exceed the upper voltage and current limits to avoid irreversible
damage of the equipment.

5 to 24V DC voltage can be applied to the input against the ground terminal marked
DC IN –.
Warning Do not exceed the maximum voltage values (24V) applied to the LOGIC IN
input to avoid irreversible damage of the equipment.
