DAC Chip
You may not even realise it, but most of us use a digital-to-analogue converter (commonly known as a DAC) daily. Built into your computers, tablets and smartphones, a DAC is fundamental to unlocking the convenience of digital music. Any device that acts as a digital sound source will need a DAC to convert digital audio to analog. A DAC converts the digital information stored in “0s and 1s” into an analog signal that's passed to speakers or headphones and ultimately our ear. In short, DACs play a large part in making digital music hearable.While this technical process is undoubtedly impressive, the DAC embedded into your smartphones or laptops is nowhere good enough to listen to your favourite music recordings in high quality. So, if you want to listen to music in high quality, an external DAC is essential to allow headphones or speakers to perform at their potential. An external DAC, first and foremost, will improve audio quality dramatically.

Wireless Range
You must have most likely noticed that wireless signals do not travel an infinite distance. The farther a wireless signal goes, the weaker it gets. This loss is known as path loss, and it defines the range of connectivity. This range of connectivity is dependent on the wireless protocol in use like Bluetooth. Three classes offer standard ranges of connectivity with Class 1 devices transmitting at 100 mW with a range of 100 meters or 328 feet. Most Bluetooth headsets and headphones are Class 2 devices that transmit at 2.5 mW with a range of 10 meters or 33 feet. Lastly, Class 3 devices transmit at 1 mW with a range of fewer than 10 meters.

DESCRIPTION
EMBEDDED WITH QUALCOMM CHIP WITH APTX HD SUPPORT
xDuoo MU-603 features the latest QCC3034 Bluetooth chip made by Qualcomm. This chip offers support for Bluetooth 5.1 connectivity which can ensure faster and more stable transmission. It also supports playback for AAC, SBC, aptX and aptX HD protocols for high-quality audio with minimal loss of quality. MU-603 also comes with an external high-gain Bluetooth antenna, which is used to ensure lossless and stable signal transmission.



EQUIPPED WITH A REFERENCE-GRADE DAC CHIP AND A 12AU7 TUBE
xDuoo MU-603 is embedded with the latest ESS ES9018K2M Sabre Reference DAC chip. This high-performance, stereo D/A converter uses the Hyperstream II DAC architecture and Time Domain Jitter Eliminator for performance that ensures high S/N and very low distortion. The audio is further processed by a 12AU7 tube, which pares back some of the shrillness of the upper-end and boosts the mids for an overall warmer “analogue” sound.


ACTS AS A PRE-AMP FOR CONNECTING IT WITH SPEAKERS
With a Bluetooth 5.1 receiver chip that lets you control your music from your phone and a 12AU7 tube that gives you that warm tube sound, the xDuoo MU-603 is a DAC/Pre-amplifier that offers the best of both digital and analogue worlds. Connect the MU-603 to your speakers using the AUX outputs for a convenient Bluetooth experience. Control the music from your phone, tablet or other wireless devices. Additionally, the MU-603’s preamplifier function will give your speakers the benefits of tube pre-amplification, with a warmer sound signature.


EXQUISITELY BUILT WITH HIGH-PERFORMANCE COMPONENTS
xDuoo MU-603 adopts the enthusiast Japanese RUBYCON capacitance as the main filter capacitor, to achieve smooth and warm sound. The RCA ports are covered in highly-conductive gold. Unlike silver and copper which corrode in the open air, gold doesn’t oxidise, making it an ideal material for audio connectors. The MU-603’s chassis is crafted by CNC machining, a computerised manufacturing process that achieves incredible precision. Built with aluminium alloy the chassis of the MU-603 resists external electronic interference to keep you hearing your music and nothing but your music.
