Genelec 4435 Smart IP In-Ceiling Installation Speaker

Introduction

The bi-amplied Genelec 4435A Smart IP

In-Ceiling loudspeaker is a high performance

in-ceiling loudspeaker for xed installations.

It requires only one CAT cable to connect,

making installation easy. The 4435A

is powered using the standard Power­over-Ethernet (PoE) technology, using

PoE+ or PoE standards. The proprietary

internal power supply in 4435A delivers an

impressive short-term SPL.

The 4435A supports Genelec Smart

IP technology, and it may be used solely,

or together with other Genelec 44xx

models. The Smart IP technology provides

scalable power, audio and loudspeaker
configuration, supervision and calibration

features via a standard CAT cable, oering

integrators unrivalled power, exibility, cost-

eectiveness and simplicity of installation.

The 4435A has been designed for

excellent sound quality and very long

lifetime and manufactured using certified

sustainable methods. All essential parts of

the loudspeaker can be recycled.

The 4435A is available in with four dierent

grille options: white or black round grille and

white or black square grille.

The 4435A loudspeaker contains

• Highly ecient dedicated Class D power

ampliers, one for each driver

• Switched-mode power supply technology

oering high SPL output using standard

PoE+ and PoE power supply with an IP
switch or power injector

• Active crossover lter

• Electronic system protection

• Audio-over-IP streaming input

• Balanced analogue line input

• Flexible room acoustic compensation tool

set built in

The 4435A is designed for indoor use,
in temperatures 15-35 Celsius and non­condencing humidity

Unpacking

A Genelec 4435A set includes the following

items. Check that nothing is missing or

damaged in transit. If there is a problem

with the product, contact your local Genelec

dealer.

• 4435A loudspeaker

• 4435A cardboard cut-out template

• Euroblock connector for analogue audio

• Square or round grille in black or white

according to order

Installation

If you are installing the 4435A to an existing

construction, examine the ceiling thoroughly

for the shortest and least obstructed

cable route. Be careful to avoid cutting or

drilling into electrical wires, ventilation or

water pipes. All of this is of course much

easier when the installation takes place in

an unfinished building where the ceiling

structure is still open. For new construction

installs, we recommend planning the
loudspeaker placement at an early stage
and using the optional Genelec New
Construction Brackets (order code 272-

0039) for marking the desired locations. The

brackets can be nailed or screwed to the
studs to show the ceiling panel installers the
places where holes for the loudspeakers are

to be located.

When installing the enclosure in an

existing ceiling, use the cardboard ceiling

cut-out template to nd the best location.

The template also shows the position of the

loudspeaker drivers and acoustic axis, so

you can easily nd the placement that brings

them to the desired position

Examine the ceiling structure carefully to

nd a clearly unobstructed location for the

loudspeaker. The loudspeaker enclosure

requires a minimum of 162 millimeters (63/8
in) of free depth measured from the outer

surface of the sheetrock. Also note that

the enclosure ange is wider than the hole

and requires about 20 millimeters (3/4 in)
of smooth ceiling surface around the hole

When you have found a good location,
check that the template is level and trace the
hole onto the ceiling with a pencil along the

outline of the template. If you are not sure

that the chosen part of ceiling is free from
obstructions, you can start by making a
smaller hole at the center of the marked area

.

through which you can probe the inside of

the ceiling. Use a drywall saw and make the

rst cut at a 45° angle toward the center of

the hole so you can put the cut piece back

in if the location is unsuitable. If you find

no obstructions, you can make the nal cut

along the marked lines.

Loosen the screws on the three mounting

latches on the 4435A enclosure a few turns

to allow the latches to turn (see Fig.3).

Connect the cables (see chapter "Cabling")

and a safety wire if one is used.

Lift the 4435A enclosure into the hole

and turn the screws clockwise so that

the mounting latches rotate outwards.

Continue tightening the screws until the
sheetrock is firmly clamped between the

mounting latches and the enclosure ange.

If necessary, a secondary safety wire can be

attached to a tab on the top of the enclosure.

Cabling

To get started, connect an Ethernet cable
from the PoE+ output in an IP switch to

the 4435A Ethernet port. Use at least CAT5

cable or better. The loudspeaker powers up

automatically. If the balanced audio input

is used, connect it before powering up the

speaker. The pin sequence is shown in

Figure 9. When the balanced line input is

used the loudspeaker must still receive PoE

power on the Ethernet cable.

To create a working system, you will need
the following:

• An IP switch with a PoE+ (802.3at) output

for the 4435A loudspeaker or an IP switch

with no PoE support and a PoE+ power

injector

• CAT 5 or higher category Ethernet cable

with RJ45 connectors

• AES67 or Dante audio-over-IP stream

source

• For 4435A setup and configuration,

a computer running Windows 10 or

Unpowered

Windows 11 operating system

• Genelec Smart IP Manager software

• Dante Controller software or Dante

Domain Manager software

Figure 4 shows an example of powering the

4435A with a PoE+ enabled IP switch. With

this method, the power budget available for
all outputs connected to the IP switch must

enable each 4435A to run at full PoE+ power.

For 4 loudspeakers, the power supply must

support 4 x PoE+ power level.

Figure 5 shows an example of powering

the 4435A with a PoE+ power injector. This

method enables the use of standard non-

PoE IP switches. Each power injector must

support full PoE+ power level into the device.

How PoE power

management works

The 4435A internal power supply stores

power for peak output. This enables the

output power to exceed the input power

for short durations (Figure 6). Music and

speck signals are dynamic. They contain

high peaks above the average level. These

peaks are supplied from the energy stored

in the loudspeaker power supply. The power

supply has been dimensioned to work with
audio and speech signals, including highly

compressed wideband audio signals. The

duration of peak output is limited more
by the PoE supply and therefore Genelec

recommends the use of PoE+ supply.

PoE budget calculation

The 4435A supports automatic negotiation
with the IP switch or IP power injector to

set the PoE power level. However, in some

cases it may be necessary to set the PoE

power level in the switch manually.

There are several Power-over-Ethernet

standards. The 4435A loudspeaker supports

the PoE+ standard but also works with

the lower power PoE standard. When the

4435A also works with lower PoE power, the
duration of high SPL output is shortened,
and long continuous output signals play at
smaller sound level than when the PoE+

power level is used. Genelec recommends

using PoE+ power level with 4435A.

Each PoE supply device (IP switch or

power injector) has a certain maximum

output power capacity. This can limit the

number of PoE outputs that can be set on.

PoE+

For 4435A loudspeaker, calculate the output
power for each output as 15 W for PoE and

30 W for PoE+. Ensure that the total power

does not exceed the switch or power injector

total power.

Example: IP switch total power is 150

W. You use PoE+ and four outputs are

connected. The total output power is 4 x 30

W = 120 W. This is smaller than the capacity

of the IP switch, 150 W. This scenario is

acceptable.

PoE cable loss calculation

There is power loss in the Ethernet cable.

The reason for the power loss is that the CAT
cable conductor is thin and has considerable

resistance. The power loss increases with

increasing cable length. The maximum cable

length is 100 meters (333 feet). Calculate

the power loss in cable at 25 mW/m or 7.4

mW/ft. The 4435A will automatically adapt to

the power loss in the cable, but lower input

power will aect slightly the duration of the

maximum SPL output. In order to minimize

the cable loss and to maximize the duration

at maximum SPL, consider using power

injectors close to the loudspeakers or short

cable runs.

Selection of IP switch

Smart IP and 4435A are fully compatible with

standard Ethernet and IP switch technology.

Genelec recommends using gigabit speed
managed IP switches with full PoE+ on
each of the outputs intended for 4435A

loudspeakers. Managed IP switches offer

the ability to congure, manage and monitor

the local area network, typically using a web
browser user interface, and this helps in

creating a well working system.

The IP switches should support Quality

of Service (QoS) and be media ready.

Differentiated services (DiffServ) typically

implements QoS prioritization of IP trac.

DiServ marks IP packets according priority.

In response, IP switches can prioritize media

traffic to improve system performance.

Dierentiated 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 4435A)

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.

This software is available for AV installers
at Genelec web site and runs on Windows

10 or Windows 11 computers. The

software allows AV installers to congure

an almost unlimited number of rooms,

zones, loudspeakers and audio channels,

and includes device discovery, a versatile
room acoustic equalisation tool set, system

organisation and status monitoring.

The 4435A contains an application
programming interface (API) supporting
control via third-party hardware, software

or house automation. The API enables

Audio-over-IP network

Audio-over-IP streaming supports unlimited

number of channels in the playback system.

These audio channels are automatically

synchronized perfectly in time by the audio-

over-IP streaming technology, forming a

single playback system. The 4435A accepts

AES67 and Dante audio-over-IP streams.

integration to all house and home automation

systems. Detailed information about the API

are provided in a separate document from

Genelec.

A balanced line input is available on 4435A

besides the IP interface. The balanced line

analogue audio input can be congured with

Genelec Smart IP Manager software.

The streams are set up with Dante Controller

or Dante Domain Manager software. Each

4435A supports reproduction of one or the
sum of two audio audio channels in the

stream. The stream audio sample rate can

range 32-96 kHz, with 16-24 bit resolution.

The 4435A contains one interface for

standard Ethernet IP network connectivity.

The network interface speed is 100 Mbps.

The interface also allows Genelec’s Smart

IP Manager software to work on the 4435A.

Setting up audio streams

The 4435A can be set to receive one audio
channel or a sum of two audio channels in

a stream. In addition, using the Smart IP

Manager software, 4435A can be set to also

sum in the analog input signal as well. Audio

stream setup is done by using Dante Controller

software. Download the software from https://

www.audinate.com/products/software/dante-

controller. Dante automatically divides a

multichannel stream into several low channel

GND

count ows suitable for the speaker and this

process is largely automatic.

An AES67 audio stream supported by the

loudspeaker can have the maximum of 8

audio channels. The 4435A can select one

audio channel or a sum of two channels in

a stream. In demanding installations, where

there is a wish for stereo reproduction at one
or more locations, stereo audio may be sent
on the network, and individual 4435A set

accordingly for L, R or L+R operation.

The AES67 compatibility mode must

turned ON to enable reception of AES67

streams. Follow these instructions:

• Double click on the loudspeaker to be

configured. The Device View window

opens

• Click AES67 Cong -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

Analogue input

An analogue audio input is provided using

a screw-mount Euroblock connector. This

enables easy connectivity and the option
of connecting the balanced audio signal to

several loudspeakers in parallel (see gure 8).

The input impedance of the analogue

input is 10 kOhm. The pin sequence of the

connector is shown in Figure 8. The number

of loudspeakers that can be connected is
set by the capability of the source device

analogue output. The loudspeakers appear

electrically in parallel, reducing the load

impedance presented to the source device.

Typically, 10 to 20 loudspeakers can be

connected on one balanced line output.

Avoid connecting 4435A to the power

amplier outputs. If this must be done, use a

balanced attenuator. Typically, an attenuation

of about 20 dB is needed. Beware that

some power ampliers can provide a signal

that exceeds the maximum voltage at the

analogue input, and this can result in failure

of the analogue input.

The automatic power function ISS (Intelligent
Signal Sensing) powers the loudspeaker
automatically down when it is not in used

and up when the use resumes. ISS can

ISS Autostart

be activated and adjusted with the Smart

IP Manager software. Powering down to

standby happens after a set time when

playback has ended. Playback automatically

resumes with an input signal exceeding the

level congured using the Smart IP Manager.

There is a slight delay in the automatic

powering up. If this is undesirable, ISS can

be disabled with Smart IP Manager.

The indented use of this loudspeaker
requires that the IP network interface is
continuously enabled also in the standby

mode. This enables the ISS to wake up with

an API command or in response to IP audio

stream. The power consumption in the ISS

state for 4435A is 4 W. To save more power,

the PoE+ power supply in the Ethernet

switch or PoE injector can be turned off.

However, loudspeaker wakeup will then take
slightly longer time and the loudspeaker
does not respond to any command on the IP

network while it is not powered.

Reset button

The factory setting for all acoustic settings is
“OFF”, sensitivity attenuator set to 0 dB, and

delay set to 0 ms. These give a at anechoic

response. Both the audio-over-IP stream and

analogue inputs are selected to play. Audio

stream settings are reset. With the factory

settings, all that is needed to play audio is
to provide a signal to the analogue input or

to congure an audio-over-IP stream in the

stream input. Set stream again to resume

normal streaming operation.

If necessary, the 4435A can be reset to
factory settings by inserting a pin through a

small hole on the front bae, near the status

indicator LED (see g. 1). Keep the button

pressed for over ten seconds. Do not use

excessive force. The loudspeaker indicates

that the reset process starts. Then you can

release the button but do not disconnect
power supplied by the Ethernet cable until the

reset process is complete. Once the reset is

complete, the loudspeaker becomes available

and active on the Smart IP Manager again.

This typically takes less than one minute.

Painting the loudspeakers

The loudspeaker metal mesh grille can be
spray painted to match the surrounding

colour. Do not paint the loudspeaker front

bae and drivers, or try to paint the grille

while it is attached to the loudspeaker. Paint

the grille separately with a thin spray. Do not

use brushes or rollers. Be careful to avoid

clogging the grille with paint.

Status indicator LED

The LED light on the front bae has some

status indication functions that are listed in

Table 2.

Automatic protection circuits

The 4435 system has protection circuits
against loudspeaker driver thermal overload

and amplifier overheating. The protection

system resets automatically so the user only
has to turn the input level down to ensure

that it does not reactivate.

Driver thermal overload protection

protects the drivers from damage caused by

prolonged overdriving with excessively high

or distorted signal. If this occurs, the circuit

automatically reduces playback volume. To

avoid this, lower the listening volume if the
sound becomes harsh and distorted at high

sound pressure levels.

Maintenance

There are no user serviceable parts within

the loudspeaker. Any maintenance or repair

should only be undertaken by qualified

service personnel.

Safety considerations

• Servicing and adjustment may only be

performed by qualied service personnel

• The loudspeaker must not be opened.

• Do not expose the loudspeaker to water

or moisture

• Do not place objects filled with liquid,

such as vases, on the loudspeaker or near
it

• This loudspeaker can produce sound

pressure levels in excess of 85 dB, which

may cause permanent hearing damage.

• Free ow of air behind the loudspeaker is

necessary to maintain sucient cooling.

Do not obstruct airflow around the

loudspeaker

• The loudspeaker is not disconnected from
the power supply unless the CAT cable is

removed from the loudspeaker.

• Ensure that the mounting in the ceiling

is able to carry the full weight of the
loudspeaker in all circumstances, the
installations have been designed and
are implemented according to the local
safety regulations and follow principles of

good workmanship. Using a safery wire is
