Product Description

Details

The Dacamp L1 is a portable headphone amplifier and DAC with dedicated processing circuits for each audio channel. It retrieves digital audio signals from smartphones, laptops, tablets and desktops and uses premium DAC components to decode, convert and produce high-resolution, true-to-life analogue audio.

The Dacamp L1 is the first device of its kind to feature dual DACs and amplifiers, with each pair responsible for one channel of high-resolution stereo audio. Each channel is independently processed by a ES9018K2M DAC and class AB amplifier in order to transmit a pure, balanced sound signal to each headphone or speaker transducer.

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. With dual ESS SABRE 32 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.

Encased in machined aluminium, the Dacamp L1 features a premium design inspired by home audio with an intuitive interface and recessed controls to prevent accidental adjustment. The case is formed using aluminium extrusion, resulting in a single, durable piece. The all-metal outer doubles as an electromagnetic shield, protecting against signal interference. 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.
