This stereo system has been designedon the basis of the EX-222.1 witch was acclaimed on numerous occasions and in particular by the French Classica magazine and was awarded by a "Choc"!

It delivers a power of 2x40W RMS into 8 Ohms and 2x60W into 4 Ohms and with its power high-performance (220VA Toroidal transformers). It includesa CD player (MP3 / WMA) as well as FM RDS and AM tuner with 40 station presets. Its USB port allows you to play your digital files on USB key in MP3 and WMA formats.

The EX712.2 includes a WIRELESS receiver allowing you to listen to music from your smatphones and talbets. It has one anolog audio input (RCA Stereo), 1 digital input (Optical and / or Coaxial conections) allowing it to connect to TVs last generation.

Finally, it provides a Subwoofer output to connect an active subwoofer. This output as a high-pass filter that can be switched on to optimise the listening in 2.1 configuration. Let this switch on “Large” position if you do not have a subwoofer.

The EX-712 includes a digital to analog converter Cirrus Logic 8415. The DAC is compatible with digital signals up to 24bits/96kHz. Its Optical and Coaxial inputs allow you, for example, to connect the audio output of your flat screen.


The EX712.2 includes a WIRELESS receiver allowing you to listen to music from your smatphones and talbets.


A power output is available at therear of the unit for the optional board. So you can, for example, add the Phono card EX-PHONO-2X without having to worry about how to power it.


A selector “Large / Small” located at the rear panel of the unit enables (or not) a high-passfilter to concentrate the power of the amplification on the rendering of high frequencies which is useful if you have connected an active Subwoofer. Thus, when the "small" position is activated, the EX-712 will leave only through high frequencies to optimize your 2.1 system listening.
For a conventional listening, in stereo without subwoofer, set the switch in the "Large" position.
