APPLICATIONS

The Unite AP4 access point is a multifunctional device
with which various applications can be realised.
With one Unite access point 4 audio channels can be
wirelessly transmitted. For a maximum of 32 channels
8 Unite AP 4 can be synchronised in one network.
Depending on the configuration, the device works as a
transmitter (Broadcast mode) or a receiver with back (Full
Duplex mode).
As a transmitter, the Unite AP4 transmits the audio signals
of an external audio source on a maximum of 4 DECT
channels. Typical applications are e.g. interpreting
services in conjunction with an interpreting system,
assistive listening and wireless microphone applications.
When using several Unite AP4 devices in different
operating modes, almost any applications can be
combined. Via the Ethernet connection, a maximum of
8 Unite AP4 devices can be integrated into a network
consisting of many Unite components. One or more
Unite AP4 devices can be configured using the free Unite
Manager PC Software. This also enables additional
functionalities in the Unite network such as monitoring,
maintenance, comprehensive configuration, pairing and
setup of transmitters, receivers, chargers and Unite AP4
access points.

How to use the Unite AP4 in a DANTE® network

The DANTE® Audio Interface (DAI) built into the Unite AP4
supports two flows in the DANTE® network at a fixed
sample rate of 48 kHz.
Each flow contains 1 to 4 channels. The configuration is
done in the free DANTE® controller of the company
Audinate®
The following combinations are possible:

• One connected device with 4 channels

• One connected device with 1 channel +
one connected device with 3 channels

• Two connected devices with two channels each

Important:

Please use shielded connector housings. Twist the shield of the cable and fold it backwards so that a connection between
the shield of the cable and the connector housing is created when crimping the strain relief of the cable.
Use either the T-568A or T-568B pin assignment for both cable ends. Do not use both pin assignments for one cable.
