AXF-100 USB Power Source HiFi Interface Preamp Int

AXF-100 USB Power Source HiFi Interface Preamp Int Description

The product is designed in accordance with the differential wiring specification at the hardware level, and has passed the industrial control-level electromagnetic interference test. The built-in power supply is directly introduced from the power supply, which isolates the USB bus power supply and prevents interference from the motherboard and other electrical equipment.
(pipeline) step filtering 2. Effectively filter ripple interference 3 Buffer for large clutter, its instantaneous buffer current can reach 5-6.8A to provide "0" Hz power supply quality for USB devices. Provide good pure power for USB-audio audio equipment.
Humanized indicator light design, work status is clear at a glance. The green light (DATA) indicates that it is in the built-in power supply state. The red light (External Power) indicates the state of external power supply; Yellow light (Build in Power) prompts whether the USB signal is connected
USB data and power supply: USB data, use good USB native signal. USB power supply, support internal/external two modes (PC SATA power supply and external power supply can be switched);
Internal and external power supply can be judged by itself, switched automatically, and protected by itself. If the external power supply is lower than 4.8V or removed, it automatically and seamlessly switch back to the built-in power supply. The equipment not be lost or damaged.

The external power supply is automatically disconnected after the PC is shut down to that the USB audio device is completely powered off, to prevent the no-load damage of the USB non-signal device, and to save the external power supply energy.
There are various options for external power supplies, especially optimized design for battery power supplies
Automatic monitoring, automatically switch to built-in power supply when the battery loses voltage or is removed, without manual selection
Automatically disconnect the external power supply without shutting down, protect equipment and save battery
Filter the power supply ripple caused by the booster circuit of the mobile power supply
Multi-band, , &2& power filter design, provide high stability, high power and pure current
Power dynamic compensation technology, automatic compensation under large fluctuations, and constant supply of pure power with ripple (less than) Less than 1Hz! Multi-mode power input seamless switching, intelligent protection design is well considered.
