This amplifier was designed in an audiophile approach to ensure the high fidelity amateur a faithful reproduction of his favourite music. It delivers 2x70W RMS of power into 8 Ohms, thanks to its high-performance 2x200VA Toroidal transformers. It includes a Bluetooth APT-X interface, allowing you to play music from your Smartphones. The EX-222 comes with 6 unbalanced audio inputs, 1 digital (optical and / or coaxial) allowing  connection to latest generation TV sets. Finally, it provides a "Pre-Out" to perform bi-amplification.

The Bluetooth® APT-X codec is an audio compression technology that was developed by the Irish company APT (Audio Processing Technology).

This codec allows playing music tracks stored on a distant source, using a wireless Bluetooth connection between two devices, source (emitter) and destination (receiver). Compatible with A2DP Stereo Bluetooth devices, Bluetooth APT-X codec offers near CD audio quality. The 4:1 average compression ratio allows high quality listening.

The APT-X audio codec is available for high quality stereo audio over Bluetooth. When incorporated in Bluetooth A2DP Stereo products, APT-X audio coding delivers full 'wired' audio quality.  With the APT-X audio codec source material is transparently delivered over the Bluetooth link, whether it is stored uncompressed or in an alternative compression (MP3, AAC, FLAC) formats.

MP3 or AAC files with a throughput less than 350 Kbits / sec are transmitted without transcoding or any loss of data. The dynamic range reaches 92 dB, for 16-bit resolution and 20 Hz to 22 kHz frequency response (such as CD-Audio). Moreover, the Bluetooth APT-X codec is compatible with Bluetooth conventional SBC systems.

The EX-222 Bluetooth® works with computers, smartphones, and tablets.

The EX-222 is dual power supply equipped, using two 200 VA Toroidal transformers. The amplifier stages share the same structure with famous EX-302, but with a doubled capacitive decoupling and a higher voltage level for final stages.

The EX-222 power stage units were designed for the most demanding speakers at very high power levels.

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