The FiiO LA UA1 is a USB filter specifically designed for use on the go. This clever noise filter comes in the form of a cable adapter and can be easily integrated into the USB power supply. The filter is equipped with a robust housing made of a lightweight but strong alloy of magnesium and aluminum for a long service life.

Mute annoying noises:
No matter which means of transport you travel with, the available USB ports on modern means of transport are not free from pollutants. This pollution is caused by the many CPUs, valves, generators and electrical consumers in the system. The contamination is usually not noticed, but when using a high quality audio component such as the M/X series FiiO players, the BTR series Bluetooth amplifiers or the Q series DAC/amplifiers, this contamination may become audible.

Surge protection:
The FiiO LA UA1 filters the 5V DC voltage supplied by the USB port and can handle up to 3 watts of power. This power filter also provides extremely convenient overload protection when the maximum power of the USB port is exceeded.
