Basic Properties
2N®SIP Speaker is a versatile sound transmission system for IP networks. It is
designed as a universal VoIP telephone with an audio output/input, button and
switched circuit connection option. It finds a variety of applications - in schools,
hospitals, office buildings, hotels, production halls, shopping centres, bus terminals,
airports and so on. You can monitor the events in the 2N®SIP Speaker area using an
integrated streaming server.
2N®SIP Speaker is a stand-alone SIP-based sound decoder and converter with an
amplifier. 2N®SIP Speaker communicates with the other audio system components
via the SIP Proxy or directly via a specified address.
Press the attached button to set up a call to up to three predefined numbers or
addresses, with calls being transferred automatically at no answer. Configure the
button function using an integrated calendar to make sure that the called subscriber is
always accessed.
You can make use of a lot of convenient VoIP services thanks to the integrated SIP
such as call forwarding at no answer (to another worksite, recording machine or
mobile phone) and call transfer (from the secretary to the required person, e.g.).
2N®SIP Speaker is equipped with a switch for you to control the electric door lock
from any telephone (by tone-entering the password).

2.1 Product Description
2N®SIP Speaker is an Ethernet audio converter designed for public sound distribution.
It is connected to and communicates with the SIP Proxy server via telephone calls.
This guarantees compatibility with all SIP-based systems.
The main principle of the 2N®SIP Speaker operation is to convert an audio signal
between the Ethernet and audio interfaces. Therefore, 2N®SIP Speaker is equipped
with an integrated 2x10W amplifier for direct loudspeaker connection.
You can control 2N®SIP Speaker with two buttons on the front panel or using an
infrared remote controller.
2N®SIP Speaker is equipped with a digital input and output, which extend the
converter options and may be helpful in special applications.
Use an integrated web interface for 2N®SIP Speaker configuration. Apply the 2N®
Helios IP Network Scanner to search all the 2N®SIP Speaker units connected.

Electric Installation Step by Step
It is very easy to connect 2N®SIP Speaker electrically. Follow the steps 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).
Caution
Be sure to connect the 2N®SIP Speaker power supply as the last step.
The same applies to PoE supply from the LAN.
Loudspeaker Connection
2N®SIP Speaker is equipped with a power amplifier for 1 (MONO) or 2 (STEREO)
loudspeakers. The loudspeakers to be used must have the nominal impedance of 4-8Ω
each. Refer to the table below for possible configurations and related maximum power
outputs (sinus, THD < 1%):

Headset/External Amplifier Connection
2N®SIP Speaker is equipped with a headset/external amplifier output. The 3.5mm
jack is available on the front panel.
Figure 2.4 Audio Output Connection
Microphone/Line Connection
2N®SIP Speaker is equipped with a microphone/external supply output. The 3.5mm
jack is available on the front panel.
Figure 2.5 Audio Input Connection
Digital Output Connection
2N®SIP Speaker is equipped with a relay switch for light signalling/external
amplifier/alarm activation. The output is available on terminals marked LOGIC OUT
and allows for switching of up to 24V/1A AC/DC loads. By default, the output is in the
NO (normally open) state.
Figure 2.6 Digital Output Connection
Warning
Do not exceed the upper voltage and current limits to avoid irreversible
damage of the equipment.

Electric Installation

Digital Input Connection
2N®SIP Speaker is equipped with a digital input for an optional button, movement
sensor or other applications. This input is available on the LOGIC IN terminal. Up to 5
to 24V DC voltage can be applied to the input against the ground terminal marked
DC IN -.
Figure 2.7 Digital Input Connection
Warning
Do not exceed the maximum voltage values (24V) applied to the LOGIC
IN input to avoid irreversible damage of the equipment.
LAN Connection
2N®SIP Speaker 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.
Figure 2.8 LAN Connection
The LAN interface is equipped with the Auto MDIX function for automatic straight/
cross-over cable detection.
The LAN interface can also be used for the 2N®SIP Speaker power supply through
active network elements or injectors meeting the IEEE 802.3af standard.
Note
With PoE, the integrated amplifier power output is limited to 5W stereo /
10W mono. To utilise the maximum power output of the amplifier, feed
2N®SIP Speaker from a 12V DC/1.8A external power supply.

Electric Installation
2.4
20
Power Supply Connection
2N®SIP Speaker 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
DC IN, or terminals marked DC IN + and DC IN –.
Figure 2.9 Power Supply Connection
Warning
If you use an adapter other than the recommended one, do not exceed
the nominal supply voltage value of 12V. Also make sure that the supply
voltage polarity is correct. Exceeding nominal values and/or incorrect
connection may lead to irreversible damage of the equipment.
