Small enough to fit where a wi-fi router would, but powerful enough to drive up to six speakers, the Monitor Audio IA40-3 is a highly versatile, installation amp.

Compact installation amp
If you’ve got two or three pairs of speakers that need a signal, but not much space for the amp, the IA40-3 is ideal. About the size of a wi-fi router, this installation amp easily fits where full size units won’t. Place it in a cupboard, bookcase or even behind your TV.

3-channel audio
For larger rooms with three pairs of ceiling or wall speakers, the IA40-3 makes the perfect amp. 3-channel audio drives up to six speakers. With a power rating of 30 watts per channel, there’s ample oomph for room-filling sound. Alternatively, use the amp in 2-channel mode and the power increases to 50 watts per channel.

Subwoofer output
In you fancy even more power, the sub output lets you connect your choice of active subwoofer. The RCA phono socket can also be used a line output for audio looping.

Bluetooth input
Featuring a built-in Bluetooth receiver, the IA40-3 accepts wireless music streaming from your smartphone, tablet or other Bluetooth enabled music source. Stream from your favourite streaming service, such as Spotify, Apple Music or Deezer, or simply tap into your stored music library.

Digital and analogue inputs
Fitted with an optical digital input, the IA40-3 is ideal for connecting a TV, games console or other digital source. There’s also a 3.5mm analogue input for any music source with an analogue output, such as a CD player.

Install-friendly
A whole host of extra features make the IA40-3 install-friendly. These include IR and RS232 interfaces – ideal for controlling the amp via your home automation system. The supplied bracket fits many purposes, including attaching to a VESA-mounting equipped TV, keeping the amp out of sight.

Get 3-channel audio from the tightest spaces, with the Monitor Audio IA40-3 installation amplifier.
