IP Smart Active Monitor
General Description
Setting up the Audio Stream
The Genelec 8430A is a two-way smart active
monitors designed for demanding professional
audio-over-IP applications using interoperable
AES67 format.
Genelec Smart Active Monitor™ (SAM™)
digital signal processing (DSP) built inside each
smart active monitor with Genelec Loudspeaker
Manager™ (GLM™) software provides unpar-
alleled acoustic quality, ease of use, and high
monitoring accuracy even in dicult acoustic
environments. The high performance drivers are
directly connected to dedicated Class D power
ampliers. System protection is implemented
as a part of the SAM signal processing.
The MDE™ (Minimum Diffraction Enclo-
sure™) enclosure is made of die-cast alumin-
ium and shaped to reduce edge diffraction.
Combined with the advanced Directivity Control
WaveguideTM (DCWTM), this design contributes
to the excellent acoustic neutrality.
Delivery Contents
Each monitor is supplied with a mains cable, two
5 meter RJ45 cables and this operating manual
Connections
When using analogue signal input, before con-
necting, switch o the monitors. Once all the
analogue connections have been made, the
monitors can be switched on.
Mains Power
The power switch is located on the back panel
(see Figure 2). Connect to a mains socket
having a protective earthed connection. These
monitors can be connected to any mains volt-
age in the range 100-240 VAC, 50-60 Hz.
GLM Control Network
To run the acoustic setup process, the monitors
and subwoofers are connected to a computer
using the GLM Adapter. An RJ45 cable is sup-
plied for this. Start control GLM control network
cabling from the GLM Adapter and daisy-chain
all monitors and subwoofers (see Figure 3). No
special sequence is necessary.
Analog Audio Input
The analog audio input on both models accepts
a balanced male XLR connector.
AES67 Audio-over-IP Input
The 8430A digital audio input accepts a Ether-
net cable (RJ45 connector) carrying an AES67
formatted digital audio signal. The 8430 can be
congured to receive one or two channels in an
audio stream.
The audio stream is set up using the web page
inside the 8430A product. Before attempting
setup, connect the monitor to the IP network
switch device. Also connect your computer to
the same network. To display this setup page,
open a web browser and write in the address
eld the product identier printed in the back of
the monitor (example of address eld content
http://8430A-xx-xx-xx.local./ for a monitor with
the address 8430A-xx-xx-xx) or alternatively
write the IP address the DHCP has assigned
for the monitor. To use the product identier
printed in the back of the monitor you must
have the Bonjour protocol installed in the com-
puter you use for the setup. The Bonjour pro-
tocol software kits are available from several
sources.
You will see a setup page. All 8430A moni-
tors on the same network are visible as sym-
bols on the top of the setup page. Select the
monitor you want to set up by clicking on one
of these. Then, use the elds in the bottom of
the page to select the stream and the chan-
.
nel in the stream for this monitor. Work through
all the speakers until you have assigned all the
inputs to monitors. We recommend you assign
a stream to input one. In some cases you
may need to manually insert the SDP session
descriptor of the stream and channel you want
to reproduce.
After you have all the inputs set, start the GLM
software and select the digital audio input. If you
followed the recommendation above, select
input channel A. To change to another audio
stream, use the web page inside the monitor.
There are some requirements for the AE67
network. The network must run a clock source
supporting the Precision Time Protocol accord-
ing to the format dened in IEEE 1588-2008.
Several audio sources and media IP switch
devices can act as PTP clock sources for the
network. It is also useful to make sure that the
IP switches delivering the audio streams have
been configured to prioritize the PTP clock
messages and the RTP audio streams over
other trac.
The global receiver delay determines the
time from the source device output to the time
of reproduction at the destination device. If this
time is too short, the samples will not arrive
to the destination device in time because of
network delay and the destination device will
discard these samples. Too large a delay can
cause the received samples to fall out of the
receiver buer and be discarded. The maximum
delay is very large and depends on the network
settings.

Settings and Acoustic Calibration
The Smart Active Monitors are extremely exi-
ble in compensating the acoustic inuences of
the room and support automated setup using
the GLM User Kit and software. The 8430A are
compatible with GLM 2.0 and later.
The GLM software can be downloaded from
Genelec web site (www.genelec.com/glm). The
GLM 2.0 User Kit is needed for the acoustic
setup and calibration. The GLM User Kit con-
tains a GLM Adapter and GLM measurement
microphone.
The GLM Adapter is connected to the com-
puter USB port and the GLM network. The
GLM measurement microphone is placed at
the listening location. Follow the instructions in
the GLM software to acoustically calibrate the
monitors.
ISSTM Autostart Function
Intelligent Signal SensingTM (ISSTM) enables very
low standby power consumption, less than 0.5
watts.
The ISS function can be enabled by click-
ing the “ISS Power Saving” pulldown menu in
the GLM software. This menu also provides a
selection of the time before entering standby.
The playback resumes once an input signal is
detected. There is a slight delay before play-
back resumes.
Mounting Considerations
Align the Monitors Correctly
Place and point the monitors so that their
acoustic axes (see gure 1) are aimed towards
the listening position. Vertical orientation is
preferred, as this minimises the sound colour
change around the crossover frequency when
the listener is moving horizontally.
