iBasso AMP14 Black Balanced Headphone Amplifier Card for DX320/300 Audio Player with 4.4mm PO and LO Dual Interface
Description:
- AMP14 selects JRC high-level low noise and low distortion volume control chip and Dual NJU72315 to create an independent volume control center. When the volume is turned down, the noise is synchronously attenuated to effectively suppress the bottom noise at normal volume.
- The internal electronic tube grounding of AMP14 adopts the separation of signal grounding and shield grounding, which effectively reduces the radiation noise received due to common grounding. In order to prevent the noise interference between the amplification circuit of the electronic tube and the subsequent drive circuit, the signal grounding of the amplification circuit of the electronic tube is isolated from the analog ground of the whole machine by using a customized gold-plated inductance with low internal resistance.
- It adopts for Toshiba 2SK209 field effect transistor.
- It adds appropriate feedback to effectively reduce distortion and expand the frequency band.
Package Included:
- 1 x AMP14 Balanced Headphone Amplifier Card
