Monitor Audio Launches New Compact Amplifier

Monitor Audio Launches New Compact Amplifier

The IA40-3 Installation Amplifier is the latest addition to Monitor Audio’s award-winning range of Custom Install audio solutions. 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 customisable brackets allow it to be positioned in multiple locations: on a wall, cabinet, stand or the back of a television.

With 40 W of power over three channels at 4 Ohms, or 60 W over two channels, the IA40-3 will drive speakers or passive soundbars to deliver a lively and precise sound.

Ideal for smaller environments, the IA40-3 can be configured in a multitude of ways: it works beautifully when paired with Monitor Audio bookshelf or stand-mount speakers in a bedroom, study or sitting room. And, in a kitchen, bedroom or loft room, the IA40-3 will perfectly power in-ceiling speakers. But, 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 bespoke bracket to drive one of our passive soundbars.

For more bass an active subwoofer can also 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® wireless technology powered by Qualcomm® aptXaudio 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. Supplied customisable brackets can be bent to fit with flexible break off sections for maximum installation versatility. Designed for modern living, the IA40-3 is Monitor Audio’s versatile solution when superior sound is required in custom install projects.

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.’
