3. Особливості продукту

The FiiO KA17 incorporates several advanced features for superior audio performance:

• 3.1 Dual ES9069Q DAC Chips

  Equipped with two ES9069Q DAC chips, the KA17 significantly reduces digital noise, achieving a dynamic range of 130dB and total harmonic distortion of -120dB. This results in a purer and more pristine audio background.

• 3.3 Ten-level Highly Precise PEQ

  Personalize your sound with the FiiO Control APP's Parametric Equalizer (PEQ). This feature allows fine-tuning of frequency, gain, and bandwidth for each PEQ band, enabling precise sound customization. PEQ adjustment supports formats up to PCM 192kHz/24bit. Note: PEQ is currently not supported in UAC1.0 mode.
