The HA500H is based on a circuit designed with technology that is completely balanced for the path of the analog audio signal inside.
The analog input unbalanced (single-ended) is converted to a balanced signal in the input buffer, and then passes into the section of ADC (Analog to Digital Converter).
The analog input balanced instead, it is passed to the ADC as it is.
For all digital audio inputs, the signal flows in the mode, fully balanced from the DAC to the output connectors.
Also, all the outputs single-ended (unbalanced) are derived from the balanced signal.
The circuit is balanced definitely helps to reduce the common mode noise and improves the overall quality of the audio signal, keeping it as close as possible.
The headphone output balanced - delivers twice the voltage and four times the power of the single-ended ( unbalanced), allowing the’HA500H to drive headphones that require plenty of power.
It also provides a better separation of the channels, eliminating the path back to the point of common ground.
The CocktailAUDIO HA500H provides you with the function selection of the output impedance of your headphones, so you can set the impedance correctly for optimum sound quality. and to achieve the best match with the sensitivity of your headphones.
