network, typically using a web browser user interface, and this helps in creating a
well working system.
The IP switches should support QoS and be media ready. Differentiated services
(DiffServ) typically implements QoS prioritization of IP traffic. DiffServ marks IP
packets according priority. In response, IP switches can prioritize media traffic to
improve system performance. Differentiated services code point (DSCP)
markings in the IP packet headers are sensed by the QoS capable IP switch.
Genelec does not endorse certain IP switch brands as Smart IP works perfectly
with all high-quality standard IP switches with these capabilities. Use of 100
Mbps IP switches is discouraged.
NETWORK STRUCTURE
Genelec recommends always designing a network structure with star topology.
Only one IP device (for example, one 4420A) should be connected at one port in
an IP switch. IP device ports should not be daisy chained to several IP devices.
Audio-over-IP requires the use of cable-based LAN network. Low-latency
uncompressed audio-over-IP streaming does not work over WLAN.
SETTING UP AUDIO STREAMS
Audio stream setup is done by using Dante Controller software. Download the
software from https://www.audinate.com/products/software/dante-controller
An AES67/ST2110 audio stream supported by the loudspeaker can have contain
the maximum of 8 audio channels. Dante automatically divides a multichannel
stream into several low channel count flows suitable for the speaker and this
process is largely automatic.
The 4420A can select one audio channel or a sum of two channels in a stream.
The AES67 compatibility mode must turned ON to enable reception of AES67 or
ST2110 streams. Follow these instructions:
•
Double click on the loudspeaker to be configured. The
Device View
window opens.
•
Click
AES67 Config
-tab.
•
In the
AES67 Mode
panel, go to
New
: and select
Enabled
.
•
In the
Reset Device
panel, click
Reboot
to reboot loudspeaker with
AES67 enabled.
