Audiofy is not only a professional audio multiroom system but your all-in-one solution for the complete control of home and building automation. Just with one device you can stream music contents from internal players or analog stereo inputs and manage in the same time all the functionalities of Thinknx supervision system from lighting and heating & cooling, to audio and music. Moreover, thanks to the integration with vocal control devices like Apple Home Kit and Amazon Echo, you’ll directly turn on or off all the commands using your voice. Through the native KNX TP port, Audiofy acts as every Thinknx controller allowing a bidirectional interaction with the plant. The new software update and the graphical restyling make the Audiofy app much more intuitive, faster and easy to use for every iOS and Android mobile devices, maximizing the performance level of the system, for a complete customer user-experience.

IMPORTANT Before connecting and using this product, please read this instruction carefully and keep it on hand for future reference. The manual is to be considered an integral part of this product and must accompany it when it changes ownership as a reference for correct installation and use as well as for the safety precautions. Pulsar Engineering s.r.l will not assume any responsibility for the incorrect installation and / or use of this product.

WARNING: To prevent the risk of fire or electric shock, never expose this product to rain or humidity (indoor use only).

1. All the precautions, in particular the safety ones, must be read with special attention, as they provide important information.

2. Power supply from mains

  • The mains voltage is sufficiently high to involve a risk of electrocution: never install or connect this product when its power cord is plugged in.
  • Before powering up, make sure that all the connections have been made correctly and the voltage of your mains corresponds to the voltage shown on the rating plate on the unit, if not, please contact your Thinknx dealer.
  • The metallic parts of the unit are earthed by means of the power cord.
  • Protect the power cord from damage. Make sure it is positioned in a way that it cannot be stepped on or crushed by objects.
  • To prevent the risk of electric shock, never open this product: there are no parts inside that the user needs to access.
  • The mains plug is used as the disconnect device and it shall remain readily operable.

3. Make sure that no objects or liquids can get into this product, as this may cause a short circuit. This apparatus shall not be exposed to dripping or splashing. No objects filled with liquid (such as vases) and no naked sources (such as lighted candles) shall be placed on this apparatus.

4. Never attempt to carry out any operations, modifications or repairs that are not expressly described in this manual. Contact your authorized service centre or qualified personnel should any of the following occur:

  • The product does not function (or functions in an anomalous way).
  • The power supply cord has been damaged.
  • Objects or liquids have got in the unit.
  • The product has been subject to a heavy impact.

5. If this product is not used for a long period, disconnect the power cord.

6. If this product begins emitting any strange odours or smoke, switch it off immediately and disconnect the power cord.

7. Do not connect this product to any equipment or accessories not foreseen. For suspended installation, only use the dedicated anchoring points and do not try to hang this product by using elements that are unsuitable or not specific for this purpose. Also check the suitability of the support surface to which the product is anchored (wall, ceiling, structure, etc.), and the components used for attachment (screw anchors, screws, brackets not supplied by the producer), which must guarantee the security of the system / installation over time, also considering, for example, the mechanical vibrations normally generated by loudspeakers. To prevent the risk of falling equipment, do not stack multiple units of this product unless this possibility is specified in the user manual.

8. Hearing loss Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When loudspeakers capable of producing high sound levels are used, it is necessary to wear ear plugs or protective earphones. See the technical specifications in speaker user manuals to know their maximum sound pressure levels.

9. Install this product far from any heat source.

10. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this product. Use a dry cloth.

Audiofy is a scalable system which delivers music contents from internal players (up to 4) or analog stereo inputs (up to 5) to stereo power amplified outputs (from 4 to 32).

Thanks to the many protocols supported, it is perfectly integrated inside automation systems. A native KNX TP port allows to send commands to the music system directly from other KNX devices and to receive feedbacks.

Through a complete set of Apps, the final user decides the routing of the audio sources and has a complete control over his music listening experience. The internal player is directly controlled from the app, the music library provided by a NAS or USB stick can be browsed with a simple menu.

Even the music stored on smartphones or tablets can be reproduced directly using AirPlay, UPnP and the outputs can always be chosen through the app!

If the user wants to listen to radio or web contents, Audiofy provides the integration of several web services so that the he can always access to his favorite music.

To expand the system and use the Audiofy E4, proper connections must be done between the master device (P1 or P4) and the expansions. The master device must be connected to the first expansion using the EXPANSION BUS connector and than all the other expansions must be daisy chained using EXPANSION IN - EXPANSION OUT connections like the picture below.

Expansions inter-connections

Figure 1.8: Expansions inter-connections

Use the provided flat cables to inter-connect the devices. Longer cables will carry degraded audio signals and the performance of the whole system will be worse.

Each expansion must be set to a different address using the DIP switches on the back. Please follow the picture below to identify expansion properly.

Once the server is connected to LAN it acquires an IP address provided from the DHCP service. To discover the IP address assigned to the server use the ”Servers Manager” tool installed with ThinKnx Configurator software (see figure ## ). This software provides a list of all the ThinKnx server (ordered by serial number) detected on the LAN and for each of them shows its IP settings. After selecting the ThinKnx server installed, it is possible to disable the DHCP service and provide it with a static IP. Click on the ”Apply server setup” to confirm the changes. This step is recommended to avoid the loss of the ip address in case the connection is lost: in fact on connection recovery, the DHCP server could not assign the same address, causing problems between server and clients.

If the server is connected on a network not served by a DHCP service, it will acquire as default address:

If a static IP address was previously set, the device is always reachable at the address: (with subnet mask

It is highly recommended to disable DHCP service and use a static IP address. Otherwise, it is possible to run into clients connection problems when the DHCP lease expires.

The server can be reached and configured from its web interface. To open the server web interface just launch your preferred internet browser (Firefox or Chrome are tested browser) and digit: http:\\serverip:5051
