Perfectly drive any headphone/IEM with 4 levels of gain and up to 15Vrms output

In order to perfectly drive the most sophisticated headphones, a device must be able to fully deliver output that matches the characteristics of the headphone.
ACRO CA1000 supports 4 levels of gain settings so that almost any existing headphones can be driven to an optimal state.

The gain setting circuitry implemented in the CA1000 can drive even high-impedance headphones without degrading the sound quality using a max output of 15Vrms.

The ACRO CA1000 unlocks the potential of headphones for a fully immersive experience.
