2x25W RMS @ 4Ω Bluetooth in-wall amplifier


The MTX iWa225 amplifier is equipped with a high performance Bluetooth input and a stereo analog input (RCA).

Its aluminum construction and small size allow it to be hidden in a wall, ceiling or cabinet without the risk of overheating. Once the 220V power supply is connected, you can enjoy music no matter if the amplifier is hidden.

The iWa225 uses "Direct Digital" amplification technology, which means there is no DAC (digital to analog converter), which eliminates loss and noise. The sound is clear, musical and very dynamic.

It is possible to simultaneously stream music to multiple iWa225 amplifiers ("multi-room") and control them from an application such as Airfoil (Available on Mac and Windows).

In the example opposite, the iWa225 is in the audio hub position. It is connected to two or four speakers (In-Wall, library ...) and it receives 2 different sources (Bluetooth and AUX).

Main characteristics :
• Very simple operation: it turns on and off by itself, no adjustment on the amp
• Sound quality: "Direct Digital" technology and output power
• Wide compatibility: Bluetooth and analog stereo inputs

Conclusion: the iWa225 is clearly the most practical and easiest amplifier to play music wherever you want.

System Diagram


The diagram above shows the iWa225 in an audio hub situation. It is connected to 2 or 4 speakers (In-Wall, bookshelf or placed on the floor) and it receives 2 sources (Bluetooth + AUX).

Simple (there is no setting on the amplifier), efficient (direct digital technology, power), flexible (double universal inputs), ultra compatible (Bluetooth, RCA), it is an essential amplifier for music everywhere without much effort!
