RHA Dacamp L1

Portable headphone amplifier and DAC with dedicated channel processors. The Dacamp™ L1 bypasses the internal sound processing components of mobile and desktop devices, using high-resolution digital-to-analogue convertors and amplifiers for clear, accurate high fidelity sound anytime, anywhere. RHA's Dacamp L1 retrieves and processes digital audio signals from mobile and desktop devices, recovering subtleties, imaging, details and depth lost as a result of inferior sound processing components; producing quality as close to the original recording as possible. The Dacamp is High-Resolution Audio certified by Japan Audio Society. With dual ESS SABRE32 ES9018K2M digital-to-analogue converters and class AB amplifiers, the Dacamp L1 has a fully balanced circuit configuration. The result is precision, reference-grade audio reproduction with support for audio formats up to 384kHz/32bit PCM and Quad DSD (11.2MHz, DSD256). In addition to three gain levels, the Dacamp L1 affords unprecedented control over bass and treble frequency ranges with physical 12-step control dials (-3dB to 9dB) to adjust sound to meet your requirements. The Dacamp L1 bypasses most devices' onboard audio components, retrieving and converting digital audio signals directly. In addition to compatibility with current smartphone OS systems (Android 4.0+ with OTG, iOS), the Dacamp L1 easily integrates into Linux, Windows and Mac operating systems. For devices without USB output and other DAC devices, the Dacamp L1's amplifier can operate via 3.5mm line in. For hi-fi seperates and consoles, the Dacamp supports mini-TOSLINK optical input. Using a 4000mAh lithium ion battery, the Dacamp L1 is able to power headphones from 12 - 600 ohms for up to 10 hours via the 3.5mm headphone out and 4-pin mini XLR connections. While not in use, it can be set to charge portable devices via USB connection.
