FEATURES
The following section describes the DMS-650 advanced features. Please read the Operation Section of this manual to learn
more on these unique features. The features are subject to change without notice or obligation.
USB AND SD CARD NAS DRIVE
The DMS-650 has expanded the function of the 3 USB-A and SD Card Slot inputs to be accessible from a networked
computer. This means when the DMS is powered on, any storage connected to the DMS will act as a NAS Drive (Network
Attached Storage). This allows you to copy your music file directly onto the USB or SD Card from a network computer
without needing to disconnect them. This simply turns any USB drive or SD Card connected to the DMS into a NAS drive.
Playback from these drives can be direct (computer-less) or monitored and controlled from a computer-based server i.e.,
JRiver, Twonky, etc., or even via Roon. What's more? If you have more than one DMS, you can play files from one DMS to
another.
MQA CERTIFIED FULL DECODING TO 768 KHZ
MQA is a technology that captures the full magic of an original studio performance. Using pioneering scientific research into
how people hear, MQA delivers master quality audio in a file that is small enough to stream or download – the days of
sacrificing quality for convenience are over. Every nuance and subtlety of the artist's performance – every tiny drop of
emotion is authentically reproduced. When you listen, you will be transported right into the very moment of creation. The
DMS-650 MQA decoder uses 16x rendering for 768 or 705.6 kHz playback. The DMS-650 uses the latest in optimization for
AKM DACs, making for an even greater musical experience.
APTX™ AND APTX™ HD WITH CARY AUDIO'S FI™ BLUETOOTH IMPLEMENTATION
Bluetooth modules are a fantastic and convenient way in which to share and listen to music from online and mobile
sources. It is not unusual for companies to use such modules as a complete end-to-end or add on solution whereby using
the cheap low-grade onboard DAC chips included in the modules and simply passing the analog signal of the module to the
analog output section. Our solution is to fully integrate (fi™) the digital information from the Qualcomm aptX™ HD
Bluetooth receiver, up to native 24 bit / 48kHz better than CD audio, into the entire digital circuit of the DMS-650. This
approach ensures that Bluetooth sources have the potential to sound like any other expensive input source whereby
utilizing our sophisticated digital topology of parallel DACs and our other integrated digital features such as TruBit™
Upsampling, and OSO™ Reclocking. Now your Bluetooth sources can truly be high fi.
ADVANCED MU-MIMO WI-FI
The DMS-650 is now compatible with the latest MU-MIMO Wi-Fi routers, which means x2 faster data transfer in the 5 gHz
band while multiple devises are accessing data simultaneously. Additionally, MU-MIMO advantages only operated at the
5Ghz band. So, if you have a MU-MIMO capable router and the DMS-650 is within a reasonable distance, set the router to
5Ghz. If the DMS-650 is much further away or on different floors than the router, the 2.4 gHz band may be better since it
uses the SU-MIMO protocol. General rule of thumb is 5 gHz band is faster for short ranges between router and device while
2.4 gHz is slower but has a greater range.
