PRODUCT INFORMATION
MODEL NAME : Genelec 4435 Smart IP In-Ceiling Speaker
Introduction
The bi-amplified Genelec 4435A Smart IP In-Ceiling loudspeaker is a high performance in-ceiling loudspeaker for fixed installations. It requires only one CAT cable to connect, making installation easy. The 4435A is powered using the standard Power- over-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, offering integrators unrivalled power, flexibility, cost- effectiveness 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 different grille options: white or black round grille and white or black square grille.
The 4435A loudspeaker contains
- Highly efficient dedicated Class D power amplifiers, one for each driver
- Switched-mode power supply technology offering high SPL output using standard PoE+ and PoE power supply with an IP switch or power injector
- Active crossover filter
- 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 non- condencing 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 bracketscan 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 find the best location.
The template also shows the position of the loudspeaker drivers and acoustic axis, so you can easily find the placement that brings them to the desired position Examine the ceiling structure carefully to find 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 flange is wider than thehole 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 first 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 final 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.
- Figure 1. Front and rear views of the 4435A
- Figure 2. Connector panel of the 4435A
- Figure 3. Screws for tightening the mounting latches are located at the edge of the front baffle
Continue tightening the screws until the sheetrock is firmly clamped between the mounting latches and the enclosure flange. 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, computer running Windows 10 or 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. 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
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.
Name | Standard | Power at switch | Min. power at 4435AA |
---|---|---|---|
PoE | IEEE 802.3af-2003 | 15 W | 13 W |
PoE+ | IEEE 802.3at-2009 | 30 W | 26 W |
Table 1. PoE and PoE+ power levels.
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 affect 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 configure, 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 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 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.
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. 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. 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 configure 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 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 configured with Genelec Smart IP Manager software.
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/dantecontroller. Dante
automatically divides a
multichannel stream into several low channel count flows 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 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
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 figure 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 amplifier outputs. If this must be done, use a balanced attenuator. Typically, an attenuation of about 20 dB is needed. Beware that some power amplifiers can provide a signal that exceeds the maximum voltage at the analogue input, and this can result in failure

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 forAV installers. Genelec recommends using the Application Programming Interface (API) inside the loudspeaker with house automation systems for the end-user control.

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
configured 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 flat 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
configure 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 baffle, near the status indicator LED (see fig. 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 baffle 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 baffle 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

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 filters 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 specific frequencies.
