Product Description

miniwatt N4 is the perfect companion for your computer, using an unique intelligent power source technology, it precisely reconstructs the analog audio signal you hear with clean and noise-free music background.

N4 combines a DAC and Hi-End Headphone Amplifier into a compact portable unit. Listen to music direct from your computer USB, lets you listen with your headphones from the 1/4" (6.4mm) jack or send your music directly to your stereo from the RCA outputs.

The simplest way to use a computer for listening is to just plug earphones/headphones into the headphone jack. However, computers are notoriously known for poor sound quality.

1) the amount of radio frequency (RF) and power supply-generated noise inside;
2) the typically poor quality of internal electronic audio components;
3) the low power supply voltages in laptops.

To completely eliminate noise from the computer, miniwatt N4 are powered by lithium battery with an Intelligent power source selection technology and are made of premium components and audiophile-grade chipsets.

Intelligent Power Source Selection:

Once miniwatt N4 is full-charged, both digital and analog components are powered by the internal battery, this unique power management technology can eliminate the internal noise and interference in your notebook and computer. Both digital and audio electronics become completely disconnected from the noisy computer power supplies. N4 is a great entry-level solution for anyone wanting to significantly improve their computer audio.
