Elfidelity AXF-100 III USB isolator audio filter for PC (newest model)
Perfect product for anyone using a PC or HTPC as a source cloud with a converter (DAC) USB.
Component-based and high-end connectivity, it will clean the USB port of the noise generated by the switching power supply while allowing injection if you wish 5V “clean” from an external source (battery, power supply Linear etc. ..).
This product integrates an advanced power management can automatically switch if for example the external power supply were to no longer power the module correctly.

For the protection of USB signals:
- Native non-bridging USB signal access, starting from the bus and drive to find the most simple level design, to avoid jitter
- Hardware layer in strict accordance with the design specifications differential traces, through industrial level of EMI test
- Built-in power supply directly introduced from the power source, completely isolated USB bus power, avoiding the motherboard, other electrical equipment interference
- Multi-band, progressive times, the ultimate power filter design provides high stability, high-purity current
- Power dynamic compensation technology, large dynamic automatic compensation, providing constant ripple
- Less than 1Hz pure power! Multi-mode power input seamless switching, intelligent protection design
- Line loss compensation accuracy: 0.01%
For USB-powered security:
- internal and external self-powered identification, automatic switching, self-protection. The external power supply is lower than 4.8 V or removed, automatically and seamlessly switch back to the built-in power supply. Device is not lost, not be damaged.
- Shutdown automatically disconnect the external power supply to ensure USB audio device is completely powered off, prevent no signal load to damage to the equipment, energy-saving external power supply.
Intelligent power optimization design
Choose a variety of external power supply (optional, using 2.1/5.5mm DC inlet – 5V), especially designed for optimizing the use of battery power
- Automatic monitoring, when battery loss of pressure and removed automatically switch to the built-in power supply, without having to manually select
- Automatic shut off external power supply, protective equipment, to save battery
- Filter mobile power supply ripple boost circuit – Perfect circuit design
