iBasso Audio AMP13 Amplifier Card For iBasso DX320/DX300 3-channel Vacuum Tube

Description: Description iBasso Audio AMP13 Amplifier Card For iBasso DX320/DX300 with 3-channel Vacuum Tube and 3.5mm+3.5mm Dual Output Description: - AMP13 selects JRC high-level low noise and low distortion volume control chip to create an independent volume control center for AMP13. 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 AMP13 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. -Add appropriate negative feedback, which is effective to reduce the distortion and expand the frequency band. - The digital part of the DX320 / DX300 and the earphone each have independent batteries, which prepare a reliable stage for the AMP13 earphone card, which requires higher power supply. AMP13 uses two high-performance power chips, a total of four DC-DC, one of which is supplied to the cathode through 1.8V low-noise LDO, and the other is supplied to the anode of the electron tube by 21V high-voltage. In addition, one circuit of + 8V and one circuit of 8V constitute the 16V voltage swing required to feed each operational amplifier. Feature: - Three-channel nutube vacuum tube amp card, 3.5mm+3.5mm dual output. - JRC low noise and distortion volume control chip - Ground separation treatment to prevent noise interference - negative feedback - Low-Noise port: 2.5Vrms / High Thrust port: 4.1Vrms Attention: - Due to the characteristics of vacuum tubes, it is easy to be interfered by Wi-Fi signals. It is recommended to turn off Wi-Fi when listening, or use the Mango Pure sound system. - It is dedicated to iBasso DX320/DX300, please update the player to the current version of firmware before use to get better support for AMP13. Package Included: - 1 x Audio Amplifier Card - 1 x Leather Case - 1 x Storage Box - 1 x Screwdriver Note: - Battery is not included.
