Monitor Audio's Introduces The IA40-3 Installation Amplifier

September 19, 2019




The IA40-3 Installation Amplifier is the latest addition to Monitor Audio's award-winning range of Custom Install audio solutions. With 40 W of power over three channels, or 60 W over two channels, the IA40-3 will drive speakers or passive soundbars to deliver a lively and precise sound.

The discreet amplifier is a highly versatile unit and features digital, analogue and bluetooth inputs with Dolby Audio (Dolby Digital) for maximum flexibility. Designed for easy installation, the amplifier's customizable brackets allow it to be positioned in multiple locations: on a wall, cabinet, stand or the back of a television.



Incredible Versatility

Ideal for smaller environments, the IA40-3 will perfectly power in-wall and in-ceiling speakers in a kitchen, loft room or bedroom. It also works beautifully when paired with Monitor Audio's smaller bookshelf speakers in a bedroom, study or sitting room.

Best of all, if there is a television in the setup, the IA40-3 can be mounted on the back of the screen using the supplied Velcro strips or customizable brackets to drive one of Monitor Audio's passive soundbars (the brackets can be bent to fit and have flexible break-off sections for maximum installation versatility).


Superb Sound

If extra bass is required, an active subwoofer can be connected to the IA40-3 via the sub/line out. Whatever the audio source, this is an amplifier with all the right connections. The IA40-3 features optical and analogue inputs and the latest Bluetooth aptX for superior pairing with mobile devices. The IA40-3 has been designed to be discreetly tucked away, with a unique heat sink fin design to aid cooling in tight spaces.

Monitor Audio's technical director, Michael Hedges, said, 'With the IA40-3, our development team really met the brief they were given and have created a compact, stylish and versatile amplifier which will delight our customers.'

Designed for modern living, the IA40-3 is Monitor Audio's versatile solution when superior sound is required in custom install projects.
