The line design of the D/A conversion part of the DAC202 is very simple.
And the DAC chip uses ESS9018S
The DAC chip is ESS9018S. The low -pass filtering simulation amplification and other parts are composed of op amp. The components are close to the components. It is not made of separate components for the entire simulation circuit like many fever equipment, and then the circuit board is a large piece. Instead, the asynchronous modules of USB and fire interfaces account for most. This design architecture is the most common in professional AD/DA.However, the difference between DAC202 and them is that the positioning of DAC202 is a civil -level audio playback equipment, so many functions are removed, and only the last part is left. This is because of the professional relationship of Weiss, and the design of many professional equipment is brought to the civil equipment. In fact, similar examples except WeISS, civil equipment such as Bechmark, Mytek and other brands have similar designs.In terms of function, DAC202 has a lot of built -in functions, which is also practical, and also has a shadow of professional equipment. It has fun and front -stage functions, and the output level of the headset output and high level simulation output parts can provide multi -level adjustment, which can correspond to the source speaker and different impedance headphones. In addition, it also has a synchronous clock I/O interface to connect the CD turntable, digital I/O card, etc., which is used to connect the synchronous clock input function. generator. Regarding this function, this may be a problem that CAS players often ignoreIn fact, a high -performance synchronous clock generator is very large to improve sound quality. Therefore, brands such as ESoteric, DCS, APOGEE have independent synchronous clock generators. But unfortunately these products are not available, most of which are professional equipment, and general users rarely have the opportunity to use it.
In addition, the digital input interface of the DAC202 provides USB and Firewire,
There are also S/PDIF and fiber interfaces. These are already standard in today''''''''s DAC
