Roland UA M10 Mobile UA USB Audio Interface

The Mobile UA is a next-generation USB audio playback interface based on Roland’s newly developed S1LKi DSP technology. This extremely compact, bus-powered USB D/A converter plays both PCM audio and ultra-high-resolution DSD audio, providing extremely high-quality sound for on-the-go music production, live performance, and listening enjoyment. With up to four channels of low-latency output, the Mobile UA can accommodate multiple listeners or independent click tracks and cue monitoring.

S1LKi DSP Audio Engine Supports Both DSD and Standard PCM Playback
The Mobile UA supports native playback of DSD audio sampled at 2.8 MHz, and our proprietary S1LKi audio engine also reproduces traditional 44.1 kHz and other PCM audio with extreme precision. By using the same type of 1-bit D/A converter used in DSD, the resulting conversion produces ultra-smooth, unclouded sound when compared to existing D/A conversion.

* 5.6 MHz DSD audio is down-sampled internally and played back as 2.8 MHz DSD audio.

Four Outputs and Ultra-Compact Design for Mobile Production and Live Performance
Ultra-compact and bus powered, the Mobile UA features quality stereo mini-jacks on both the left and right sides. Two people can monitor audio at the same time, or a single musician can use one side for the main output and the other for cue monitoring or a click track. Low-latency ASIO and Core Audio performance provides compatibility with a wide range of professional applications.
* When a jack on one side is configured as an Aux output, any volume adjustments you make on the unit will not be reflected on this jack.

High-Performance Headphone Monitoring in Loud Environments
Featuring two channels of 158 mW output at 40 ohms, the Mobile UA’s high-level headphone out supports monitoring situations where isolation from ambient sounds, nearby performers, and crowd noise is essential.

Low Latency for Music Creation and Sound Editing
The Mobile UA inherits Roland’s acclaimed VS Streaming technology for low latency and stable operation, and USB audio streaming and DSP are processed on a single custom chip. This provides mobile music creators pro-level performance for playing virtual instruments and editing tracks in DAW software.

What is DSD?
DSD, or Direct Stream Digital, is a technology for digitizing audio using much higher frequencies than the typical PCM format. Each sample is recorded as a single bit at a sampling rate of 2.8 MHz, which is 64 times that of audio CDs (44.1 kHz). DSD formats that use 5.6 MHz, or 128 times that of CDs, are also widely used. Because DSD is capable of recording at higher levels of precision than audio CDs, it is primarily used for recording and music distribution.

Sublime Sound Delivered by Roland's Proprietary S1lki DSP You’ll instantly notice the difference with the Mobile UA’s superior sound—it’s extremely smooth, provides exceptional imaging, and is devoid of any muddiness. The secret is Roland's proprietary DSP technology called "S1LKi" (pronounced "silky"). Processes that are usually performed at the DA converter stage, such as sample rate conversion and various filter processes, are performed right in S1LKi. This enables DA conversions under near-ideal conditions, regardless of the sampling rate. Signal processing of the original file is performed optimally and with unprecedented musicality, and even 16-bit/44.1 kHz PCM files exhibit an astonishing level of sound quality.	Audiophile-Grade Sound in Both PCM and DSD Formats The Mobile UA faithfully reproduces the finest sonic details and delivers optimal monitoring performance through all aspects of the mixing and editing processes. As a high-quality USB audio interface, it truly shines when listening to high-res sound sources. It supports both PCM (up to 352.8 kHz) and DSD (up to 5.6 MHz), and is unparalleled in offering un-dithered, un-truncated 32-bit floating point PCM audio from your DAW. And with 2.8 or 3.1 MHz DSD audio sources, you can enjoy native high-res audio playback with no resampling.	Super-Lightweight and Compact Body Fits in Your Palm The Mobile UA fits in the palm of your hand and weighs only 130 grams, packing an exceptional level of quality into a surprisingly compact device. From the dual stereo mini-jacks that reside on each side and volume button with mute functionality to the beautifully designed high-resolution level indicators and USB bus power, the Mobile UA provides unprecedented performance anywhere life takes you.	Premium Headphone Amp with Ultra-Powerful Output The Mobile UA's stereo headphone amp delivers 158 mW of power on each channel, providing super-high output that produces more than enough volume, even when using high-impedance headphones. On stage and in other high dB situations, you won’t need a mixer or external headphone amp to ensure proper volume levels, giving you precise monitoring in just about any environment.
