The premium, standalone SHA900 Portable Listening Amplifier features a USB digital-to-analog-converter (DAC) that converts analog or digital audio from portable digital audio sources and computers. For use with high-quality headphones and earphones, the SHA900 features a 24 bit/ 96 kHz conversion rate, customizable 4-band parametric EQ with five standard and 4 user-defined settings, rechargeability and input level meters. The SHA900 can process both digital audio directly via micro-USB, analog via a direct line in, or bypass entirely for a pure analog signal without conversion. The SHA900 defines a new standard of portable listening that brings high-fidelity audio into the mobile demands of today’s active lifestyles.
