Genelec 4436 Smart IP Pendant Installation Speaker

Introduction

The bi-amplied Genelec 4436A Smart IP

Pendant loudspeaker is a high performance

pendant loudspeaker for xed installations.

It requires only one CAT cable to connect,

making installation easy. The 4436A

is powered using the standard Power-

over-Ethernet (PoE) technology, using

PoE+ or PoE standards. The proprietary

internal power supply in 4436A delivers an

impressive short-term SPL.

The 4436A 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 4436A 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 4436A 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 4436A is designed for indoor use, in

temperatures 15-35 degrees Celsius and

non-condencing humidity

Unpacking

A Genelec 4436A 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.

• 4436A loudspeaker

• Euroblock connector for analogue audio

• A round grille

• A 5 metre (16 ft 7/8 in) adjustable hanging

wire

Installation

If you are installing the 4436A 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.

Cabling

To get started, connect an Ethernet cable

from the PoE+ output in an IP switch to

the 4436A 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 4436A 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 4436A setup and configuration,

a computer running Windows 10 or

Windows 11 operating system

• Genelec Smart IP Manager software

• Dante Controller software or Dante

Domain Manager software

Figure 3 shows an example of powering the

4436A with a PoE+ enabled IP switch. With

this method, the power budget available for

all outputs connected to the IP switch must

Figure 1. Front and rear views of the 4436A enclosure

enable each 4436A to run at full PoE+ power.

For 4 loudspeakers, the power supply must

support 4 x PoE+ power level.

Figure 4 shows an example of powering

the 4436A 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 4436A internal power supply stores

power for peak output. This enables the

output power to exceed the input power

for short durations (Figure 5). 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 4436A 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 4436A loudspeaker supports

the PoE+ standard but also works with

the lower power PoE standard. When the

4436A 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 4436A.

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.

For 4436A 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 4436A 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 4436A 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 4436A

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 4436A)

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.

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 4436A accepts AES67 and

Dante audio-over-IP streams. The streams

are set up with Dante Controller or Dante

Domain Manager software. Each 4436A

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 4436A 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 4436A.

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 4436A contains an application

programming interface (API) supporting

control via third-party hardware, software

or house automation. The API enables

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 4436A

besides the IP interface. The balanced line

analogue audio input can be congured with

Genelec Smart IP Manager software.

Setting up audio streams

The 4436A 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, 4436A 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

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 4436A 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 4436A 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

congured. 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 7. 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 4436A 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.

Genelec Smart IP Manager

software

Acoustic calibration, zone setup, input

selection and loudspeaker management

are done using Genelec Smart IP Manager

software. This is a software intended for

AV installers. Genelec recommends using

the Application Programming Interface

(API) inside the loudspeaker with house

automation systems for the end-user control.

Download Smart IP Manager at https://

www.genelec.com/smart-ip-manager

and follow screen instructions to install.

For detailed use of the Genelec Smart IP

manager software, please refer to Smart IP

Manager operating manual.

ISS Autostart

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

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 4436A 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. 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 4436A 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 4436 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

• 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

recommended

Maximum short-term output level is limited by the PoE technology being used and the crest factor of the audio signal. The stated values are typical for music and speech signals.

Maximum long-term output level can be further limited by loudspeaker system protection. Genelec recommends using PoE+ whenever possible. Using lower-power PoE can limit short-term

maximum and long-term maximum, depending on the characteristics of the signal being reproduced.

User selectable lters can be set to positive gain. Positive gain must be used with care as it is possible to cause premature overload of the loudspeaker at specic frequencies.
