FEATURES
The following section describes the DMS-500/550/600 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.
MQA CERTIFIED FULL DECODING TO 768 KHZ
The DMS-500/550/600 are fully MQA Certified with the DMS-550/600 using 2
nd
generation MQA
decoder filters, and the DMS-500 utilizing 1
st
generation decoder filters. 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's 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'll be transported right into the very moment of creation. The DMS-
500/550/600 are the first of MQA's partner to offer 16x rendering of MQA files, meaning all MQA
files will play at 768 or 705.6 kHz sampling rates.
aptX™ & 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's 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.
fully integrate (fi™)
Our solution is to
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-550/600. The DMS-500 standard aptX™ is capable CD quality 16 Bit / 44.1 kHz. 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
fi
Bluetooth sources can truly be high
.
BUILT-IN HEADPHONE AMPLIFER (DMS-550 ONLY)
The DMS-550 is also a high-performance Class-A headphone amplifier DAC/streamer for all you
digital sources. Great pains have been taken to ensure a rich headphone experience with widest
range of compatible headphone impendences. The headphone sections incorporated its own
independent volume control so as to not interfere with your setting on your main volume output
settings.
ADVANCED MU-MIMO WI-FI (DMS-550/600)
The DMS-550/600 are now compatible with the latest MU-MIMO Wi-Fi routers, which means x2
faster data transfer in the 5 gHz band while multiple devise 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-550/600 are within a reasonable distance, set the router to 5Ghz. If
the DMS-550/600 are much further away or on different floors than the router, the 2.4 gHz band
may be better, especially with the DMS-500 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.
