This system is great for your bathroom, wet room or shower room. The speakers are IP35 Rated which means they will be able withstand the water from a shower hitting it for a short time. We recommend installing these speakers not directly under any water source and this will ensure they last longer. 

This is a Class-D mini amplifier driving 2 x 20W power with WiFi streaming capability.

Controlled from an Android or iOS smart device, the STA40-WIFI is compatible with freely available apps to stream music, radio and podcasts directly from the local wireless network.

Embedded internet radio offers high quality digital audio from almost any online radio station or podcast available worldwide.

Subscription services can store online playlists which can be cast directly from the internet without requiring the smart phone to be connected to the network.

A line input is selectable for connection to a TV, CD, DVD or other playback device if required.

If you would like to add a subwoofer to this system, we would recommend the Adastra M8S Active Subwoofer.

Wifi Vs Bluetooth?

Wifi has a much larger range (If you are connected to your Wifi, you'll be able to control the speakers) whereas Bluetooth normally only has 10m range. 

No interruptions with Wifi, whereas Bluetooth, when either a notification or a call comes through to the device then it will stop the music.

Wifi allows you to group amplifiers together so that they all play at the same time in perfect sync, whereas Bluetooth is a single room solution

How to Install?

Essentially the Amplifier is the brain of the system and all wires come back to this unit.

The power is supplied as a plug and an inline transformer.

Then simply run speaker cable from the Amplifier to each of the speakers (Each speaker needs its own 2 core speaker cable running to it.)

Once installed the STA40 amplifier is ready to be set up, to do that you'll need to download the MUZA Player app and follow the easy set up process.

After the amplifier is linked to your network, you'll be able to rename it so that you know which speakers are in what room.
