Monitor Audio IA40-3 Installation Amplifier

Ideal for smaller environments, the IA40-3 Installation Amplifier will perfectly power in-ceiling speakers in a kitchen, loft room or bedroom. It also works beautifully when paired with Monitor Audio 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 behind the screen – using the supplied bespoke bracket – to drive a Monitor Audio Passive Sound-bar (The customizable brackets can be bent to fit and have flexible break-off sections for maximum installation versatility).

With 40 watt of power over three channels at 4 ohms, or 60 watt over two channels, the IA40-3 will drive speakers or passive sound-bars to deliver a lively and precise 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® wireless technology, powered by Qualcomm® aptX^TM Audio, to allow easy and superior pairing with mobile devices. The IA40-3 has been designed to be discreetly tucked away and its unique heatsink fin allows cooling in the tightest of spaces.

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