USER MANUAL AKB90WIFI Monacor

WLAN Hi-Fi Multi-Room Amplifier These instructions are intended for users with basic knowledge of wireless network technol- ogy. Please read these instructions carefully prior to operating the amplifier and keep them for later use. 1 Applications The amplifier AKB-90WIFI is designed to reproduce music in hi-fi quality via a wireless local network (WLAN). A DLNA-enabled audio player installed on a smartphone, tablet PC, computer etc. is required as a player. Some DLNA audio players provide a multi-room option: an AKB-90WIFI is installed in different rooms; using a DLNA player, different pieces of music can be transmitted to the individual amplifiers.

3 Safety Notes The unit (amplifier with power supply unit) corresponds to all relevant directives of the EU and is therefore marked with

The unit is suitable for indoor use only. Pro- tect it against dripping water and splash water, high air humidity and heat (admissi- ble ambient temperature range: 0–40°C

Do not place any vessel filled with liquid on the unit, e. g. a drinking glass.

Immediately disconnect the mains plug from the socket

1. if the amplifier, the power supply unit or

the mains cable is visibly damaged,

2. if a defect might have occurred after the

unit was dropped or suffered a similar accident,

3. if malfunctions occur.

In any case the unit must be repaired by skilled personnel.

Never pull the mains cable to disconnect the mains plug from the socket; always seize the plug.

For cleaning only use a dry, soft cloth; never use water or chemicals.

No guarantee claims for the unit and no l ia- bility for any resulting personal damage or material damage will be accepted if the unit is used for other purposes than originally intended, if it is not correctly installed or operated or if it is not repaired in an expert way.

3.1 Conformity and approval

Herewith, MONACOR INTERNATIONAL declare that theunit AKB-90WIFI is in accor- dance with the basic requirements and the other relevant regulations of the directive 2014 / 53 / EU. The declaration of conformity is available on request from MONACOR INTERNATIONAL. The unit operates in the 2.4 GHz range and is generally approved for operation in EU and EFTA countries and is licence-free. 4 Installation

1) Place the amplifier at a suitable location

and, if required, fasten it using screws.

2) Insert the antenna (1) into the jack ANT (2);

then tighten the antenna and place it in a vertical position.

3) Connect the speakers to the jacks (5)

[Right OUT for the right channel, LEFT OUT for the left channel]. To obtain the highest output power, connect speakers with an impedance of 4 Ω. It is also possible to connect speakers with higher impedance; this, however, will reduce the output power accordingly.

4) Finally, connect the power supply unit to

the jack DC IN (3) and the mains plug to a mains socket (230 V~ / 50 Hz). The ampli- fier will be switched on. When the amplifier is not used for a longer period of time, disconnect the power supply unit from the mains socket to save power. If the unit is to be put out of operation definitively, take it to a local recycling plant for a disposal which is not harmful to the environment. WARNING The power supply unit uses dan- gerous mains voltage. Leave servicing to skilled personnel only. Inexpert handling of the unit may result in electric shock.All rights reserved by MONACOR INTERNATIONAL GmbH & Co. KG.

1) At the player (smartphone, tablet PC, com-

puter, etc.), switch on the WLAN function.

2) Establish the connection to the amplifier.

On the player, the amplifier will be indi- cated by “WiFi-HiFi_” and four digits. Each amplifier has a digit sequence of its own so that it is possible to select individual ampli- fiers when multiple amplifiers are used.

3) Start the DLNA player.

5.1 Configuring the AKB-90WIFI

The amplifier can be configured by means of the integrated web server. Enter the IP address of the AKB-90WIFI in an Internet browser: 10.10.10.254 It is, for example, possible to change the shown name “WiFi-HiFi_xxxx” and the menu language of the web server or to install the latest firmware. To reset the amplifier to its factory settings, keep the pushbutton RST (4) pressed for at least 5 seconds.

5.2 Connection to a WLAN router

• With the WPS function (WiFi Protected Setup), the AKB-90WIFI can be easily con- nected to a WLAN router provided that the router supports WPS: Briefly press the push- button RST (4). The AKB-90WIFI will auto- matically transfer the data required to a WLAN router in the reception range. As an alternative, use the web user inter- face of the AKB-90WIFI to connect it manu- ally to a router, e. g. when WPS is not sup- ported by the router. 6 Specifications Amplifier RMS output power: × 45 W at 4 Ω Amplifier class: p. 2
