New Flagship AK4495SEQ + AK4118 Decoder Board Amplifier without USB Sub-Card for Audio

New Flagship AK4495SEQ + AK4118 Decoder Board Amplifier without USB Sub-Card for Audio

Description:
AK4495SEQ decoder board kit, no sub card, but containing LME49860 amps, needs weld it yourself.  (The schematic diagram and technical support are available for the process, also can weld the chip IC for you as free.)

If your previous DAC is WM8741 AK4399 CS4398 PCM1794, this product is very suitable for you to upgrade, using the AK4118 soft control to input control, so that decoding process is in the best condition.

The AK4495SEQ is the super version of AK4495EQ , much accurate and hearing better, high performance with 32-bit stereo DAC, can achieve 123 db dynamic range, stereo and 126 db are mono output  ( with optional analog supply 7V ). Use a symmetrical layout for the left and right channels of innovative design techniques can prevent deterioration of signal quality, as well as a 32-bit number crunching module provides a complete 32-bit processing.

The AK4495S integrates a newly developed circuit for rich bass sound field with less distortion of music playback experience. As a sound consideration, VDD, VREFH, VSS and VREFL pin assignments for each L and R channels. In addition, each of these L and R channels has two labels, in order to avoid affecting the common impedance and to achieve a low impedance performance possible. .

VRDS-NEO VMK-3.5-20S turntable is used AK4495 DAC as a core .

This product is a kit , needs welding yourself,  in order to play the performance AK4495, using a top digital input processing chip AK4118, ultra-precision voltage regulator chip LT1963 and KG KZ WIMA capacitors, FR4 resistance.  

Trial dynamic performance is very good, especially the bass is very good, the sound field is very good, real and natural. If the amp with OPA2604 will be very good actually.

Enter button is used to make input switching, respectively fiber optic, coaxial, USB input. If you want to realize USB capabilities, you need to buy USB sub card.  The circuit does not debugged, it can work when the installation is ok.
