The amplifier stage also incorporates an adjustable gain level, called PowerMatch. This feature allows the gain to be adapted according to the impedance of the headphones used, adjusting the input sensitivity and thus the strength of the signal. For example, with high-sensitivity in-ear headphones, the PowerMatch function at its lowest level results in an extremely low noise level. When listening with high impedance headphones, activating PowerMatch increases the gain for a higher output level.
The HIP DAC offers 2 headphone outputs: the first one is a 3.5mm jack for a single-ended link and the second one is a 4.4mm Pentaconn jack, allowing a connection with a balanced headphone and thus to take advantage of the balanced architecture of the HIP DAC.
In addition, the 3.5mm jack output benefits from proprietary S-Balanced technology, significantly reducing crosstalk and distortion for use with unbalanced headphones. A particularly useful feature with in-ear headphones.
