The DA&T K422 is a superb all-in-one amplifier for your high-end audio needs. Compact, elegant, multi-functional and lightweight. Plug in your music source and you are good to go.
> Bi-Amping
The DA&T K422 includes two sets of amplifiers – a dynamic Class-A amplifier and a Class-D amplifier. Class-A offers the best all-round distortion characteristics while Class-D offers the highest efficiency and comparable distortion characteristics in the 2kHz and below mid-bass region. You can connect the mid-bass unit to the Class-D output and the tweeter to the Class-A output to enjoy the best of both designs. You can also decide to use only the Class-A or Class-D amplifier if your speaker does not support bi-amping.
> Adjustable Dynamic-A Gain
The performance of your music system is affected by the audio environment. Some environments may be too bright, and others too dark. When used in bi-amping mode, the DA&T K422 enables you to adjust the Dynamic-A gain(from 12x to 26.8x) to change the frequency response of your music system to match the environment and achieve coherent frequency response.
> Ample Power
The DA&T K422 outputs 145W@8ohms and 240W@4W in Class-D, 145W@8ohms and 260W@4ohms in Class-A and is capable of supporting most speakers.
> Excellent Digital Capabilities
The DA&T K422 comes with an integrated 32-bit DAC capable of 384kHz/32-bit and DoP128 digital audio when connected via coaxial inputs and 384kHz/32-bit, DSD Native 256 and DoP128 digital audio via USB.
> Excellent Connectivity
The DA&T K422 supports connections via analog, optical digital and coaxial digital inputs. It also supports hi-resolution Bluetooth to enable you to play your favourite music through mobile devices. It also supports direct analog input.
