Genelec 8430A

IP Smart Active Monitor

Operating Manual

8430A

General Description

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 dicult acoustic

environments. The high performance drivers are

directly connected to dedicated Class D power

ampliers. 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

Waveguide TM (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

congured to receive one or two channels in an

audio stream.

Setting up the 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 identier 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 identier

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 dened 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 trac.

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 buer 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 inuences 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.

> 0,7 m

ACOUSTIC

AXIS

H = 190 mm (7 1/2 in)

Maintain Symmetry

Place the monitors at an equal distance from

the listening position and symmetrically relative

to the room walls. Place the listening position

on the room front-back centreline and the moni-

tors at an equal distance from this centreline.

Minimise Reections

Acoustic reflections are created by objects

close to the monitors. Such objects can be

desks, cabinets, computer monitors etc.

Acoustic reections can cause unwanted sound

colouration and sound image instability. These

can be minimised by placing the monitors and

the listening position clear of reective surfaces.

Minimum Clearances

Ensure sucient clearance for amplier cooling

and reex port function. The minimum clearance

is 3 cm (13/16 in) behind, above, and on both

sides of the monitor. The ambient temperature

should be less than 35 degrees Celsius (95°F.

)

Mounting Options

The Genelec 8430A oers the Iso-Pod™ (Isola-

tion Positioner/Decoupler™) vibration insulat-

ing stand allowing tilting of the monitor acous-

tic axis towards the listener. The bottom of the

monitor has a 3/8 in UNC thread. The rear has

two M6 x 10 mm threads for wall or ceiling

mounts. Genelec oers a selection of mounting

accessories.

Safety Considerations

Servicing must only be performed by qualied

service personnel. The monitor must not be

opened.

• Do not use the monitor with an unearthed

mains cable or an unearthed mains

connection.

• Do not expose the monitor to water or

moisture. Do not place any objects lled

with liquid, such as vases, on the monitor

or near it.

• This monitor is capable of producing

sound pressure levels in excess of 85 dB,

which may cause permanent hearing

damage.

• Free ow of air behind the monitor is

necessary to maintain sucient cooling. Do

not obstruct airow around the monitor.

• The device is not completely disconnected

from the AC mains service unless the mains

power cord is detached from the device or

the mains outlet.
