IMPORTANT SAFETY INSTRUCTIONS
WARNING: The triangle with the lightning flash symbol
displayed on the unit advises the user of dangerous un-
insulated voltage inside the product’s enclosure.!
CAUTION: To reduce the risk of electric shock, do not
remove the cover. There are no user-serviceable parts
inside; it is recommended that only qualified personnel
service this component.
ALERT: The triangle with the exclamation point symbol on the component suggests that the owner refer to important
operating and maintenance instructions in the owner’s manual.
1. OWNER’S MANUAL: Before powering up the equipment, read all safety and operating instructions and follow them as
instructed. Retain the safety and operating instructions for future reference.
2. ATTACHMENTS: Use only those attachments recommended by the unit manufacturer, as others may cause hazards.
3. ACCESSORIES: Do not place the unit on an unstable cart, stand, tripod, bracket, or table. The unit may fall, causing
injury to a person or damage to the unit. Mount the unit according to the manufacturer’s instructions with the
suggested mounting accessory.
4. WALL OR CEILING MOUNTING: Mount the unit to a wall or ceiling only in the manner recommended by the
manufacturer.
5. WATER AND MOISTURE: Do not use the unit near water (for example, near a swimming pool, bath tub, wash bowl,
kitchen sink, or laundry tub) or in a damp environment (like a basement or outside in the rain).
6. OBJECT AND LIQUID ENTRY: Do not push objects of any kind into the unit through openings as they could touch
dangerous voltage points and short-out parts, possibly resulting in a fire or electric shock. Avoid spilling liquid of any
kind on the unit. If water or any metal object (such as a paper clip, coin, or staple) accidentally falls inside the unit,
disconnect it from the AC power source immediately and contact Cary Audio Design for further instructions.
7. HEAT: Position the unit away from heat sources such as radiators, heat registers, stoves, or other units (including
amplifiers) that produce heat.
8. VENTILATION: Slots and openings in the cabinet create ventilation to protect the component from overheating. These
openings on the top and bottom panels must remain unobstructed. Allow at least 6 inches (16cm) of clearance above
the unit and an opening behind the unit for airflow. Do not place the unit on a bed, sofa, rug, built- in bookcase, or
rack without adequate ventilation.
9. GROUNDING OR POLARIZATION: As a safety feature, the unit may be equipped with a polarized alternating
current line plug in which one blade is wider than the other. This plug will fit into the power outlet only one way. If you
cannot insert the plug fully into the outlet, try reversing the plug. If the plug still will not fit, contact a licensed
electrician to update your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
10. POWER SOURCES: Operate the unit only from the power source indicated on the marking label. If you are unsure of
the type of power supplied to your home, consult your unit dealer or local power company.
11. POWER CORD PROTECTION: Arrange power supply cords so that they do not suffer from foot traffic or pinching by
items placed on or against them. Pay close attention to cords where plug enter the AC outlet and where they exit from
the unit.
12. LIGHTNING: For added protection during a lightning storm or when the component is idle for long periods of time,
unplug the unit from the wall outlet and disconnect the antenna or cable system. This will help protect the unit from
lightning and power line surge damage.

for use with this product, but other AC cords ma y be used. Consult your dealer for advice
on AC power cords and high quality wire in your system.
•AC Fuse: The fuse is located inside the chassis and is not user serviceable. If the unit does not power up,
contact an authorized service representative
•Wiring: Cables running inside walls should have the appropriate markings to indicate compliance and listing
by the UL, CSA or other standards required by the UL, CSA, NEC or your local building code. Questions
about cables inside of walls should be referred to a qualified custom installer, a licensed electrician, or low-
voltage contractor.
18. RECORDING COPYRIGHT: Recording of copyrighted material for other than personal use is illegal without
permission of the copyright holder.
19. NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer's attention to
article 820-40 of the NEC, ANSI/NFPA 70, which provides guidelines for proper grounding and, in particular,
specifies that the cable ground shall be connected to the grounding system of the building as close to the point of
cable entry as practical.

FEATURES
!
!
!
The following section describes the DMS-500 basic features. Please read the Operation Section of this
manual to learn more on utilizing these features. The features are subject to change without notice or
obligation.
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.
Our solution is to fully integrate (fi™) the digital information of the CSR aptX® lossless Bluetooth
receiver into the entire digital circuit of the DMS-500. 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 .
TruBit™ DSD & PCM Upsampling
Upsampling can be messy, leaving behind lots of digital artifacts resulting in noise and inaccurate
signal generation. On the surface, upsampling may seem like a good idea. But if not implemented
properly it can be disastrous. Many DACs use modest DSP chips at best, or worse, the DAC chip
itself to upsample all incoming digital signals. Typically, this is done as a predefined one-size-fits-
all sample rate, such as 96 kHz, 384 kHz, etc. On the contrary, Cary Audio’s TruBit™ Upsampling
is a sophisticated and powerful process utilizing a dedicated 128 bit DSP engine which allows for
up to 10 different selectable TruBit™ sample rates and an increased bit depth of 32 bits. Working
in tandem with our OSO™ Reclocking feature, the newly generated signal is cross-checked multiple
ways ensuring that the selected upsample rate is as if it were an original native signal. The result
is a signal free from digital artifacts that sounds accurate, pure, and a joy to listen to.
PCM TO DSD CONVERSION
Within the TruBit™ Upsampling the DMS-500 can convert any PCM inputs to true DSD256 output.
Now with PCM to higher PCM, or PCM to DSD upsampling even the most strident of PCM and DSD
proponents can have their cake and eat it to. PCM to DSD conversion takes our TruBit™
technology to whole new level of pure silky smooth analog like sound like never before from digital
sources.
OSO™ RECLOCKING
!
Once a digital signal is transferred into Cary Audio’s digital ecosystem via the digital inputs, it is
processed with extreme care to ensure the best possible sound achievable. As a digital source
transfers from one point A to point B it creates an insidious digital problem called ‘jitter’. To deal
with this, Cary Audio uses something we call OSO™ Re-clocking. This solution re-clocks all signals
again once onboard as to ensure all jitter is virtually eliminated to a minute degree. We call this
OSO™, short for “Onboard Signal Origination” because this re-clocking and buffering creates a
signal so stable and jitter free it’s as if the origin of the signal was generated onboard and not from
an external source.

VARIABLE VOLUME CONTROL
!
!
The volume control is located on the hand held remote. The DMS-500 will display a pop-up as
shown below when adjusting volume for all Network, USB/SD, and Internet sources.
Note: For SPDIF sources, the volume is on-screen at all times.
USING AS A SOURCE (CONNECTING TO A PREAMPLIFER, ETC.)
When using the DMS-500 as a source unit and connecting to a preamplifier, integrated amplifier, or
receiver, it is recommended to set the volume to “Independent Volume”. The Independent Volume
setting allows for adjusting the volume to each input of the DMS-500 to volume match the output of
multiple connected sources. This is useful if some sources have a much greater or lesser output and
you find yourself having to constantly turn your preamplifier’s volume up or down to reach a
comfortable level upon changing DMS-500 inputs. For the greatest sonic benefit, it is recommended
to set the volume to max volume 8.0 (3.0 volts). However, please check your associated
equipment’s documentation to be sure it can accommodate a 3.0 volt input. Otherwise, set the
volume/voltage level that match the highest acceptable input voltage of your associated equipment.
Note: The default Reset Independent Volume setting is -13.5
USING AS A DIGITAL PREAMPLIFIER (CONNECTING DIRECT TO AN AMPLIFER)
When using the DMS-500 as a digital preamplifier (connecting it directly to an amplifiers inputs), it is
recommended to set the volume to “Master Volume”. This will output the same volume for all
connected sources. If using the DMS-500 as a digital preamplifier, be sure to turn ON the DMS-500
BEFORE turning on your amplifier. Then, set the DMS-500 volume to - 98.5 (or mute).
Only after being sure the volume is turned down, turn on your amplifier and gradually turn up the
DMS-500 volume to an appropriate listening level. Otherwise, extreme damage may occur to your
amplifier, speakers or hearing.
Note: The default Reset Master Volume setting is -30.0
