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. 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-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 Bluetooth sources can truly be high fi.

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.

TruBit™ DSD & PCM Upsampling & PCM to DSD CONVERSION

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. Typically, upsampling is done as a predefined one-size-fits-all approach, such as 96 kHz or 384 kHz. Utilizing a dedicated 128 bit DSP engine, Cary Audio's TruBit™ Upsampling allows for up to 10 different selectable sample rates and an increased bit depth of 32 bits. The result is a signal free from digital artifacts that sounds accurate, pure, and a joy to listen to. What's more, PCM sources can be converted to DSD (DSD64, 128, or 256). Alternatively, a lower native DSD source can be Upsampled to a higher DSD rate. PCM to DSD conversion and DSD upsampling 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 developed 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.

The operation of the DMS-500/550/600 assumes all users have a minimum of a moderate level of understanding of computers, file sharing principles, computer networks, and other associated peripherals such as: routers, Ethernet, Wi-Fi, USB hard disc and flash drives, SD Cards, NAS drives, computer operating systems, third party software such as media/music servers and media players, digital music downloading and storage, music library and file management such as tagging, imbedding of artwork, etc.

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-500/550/600 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-500/550/600 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-500/550/600 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 AMPLIFIER)

When using the DMS-500/550/600 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-500/550/600 as a digital preamplifier, be sure to turn ON the DMS-500/550/600 BEFORE turning on your amplifier. Then, set the DMS-500/550/600 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-500/550/600 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

USING AS A HEADPHONE AMPLIFER (DMS-550 ONLY)

The DMS-550 has independent volume control for headphone use. When inserting headphones into the 1/4 " jack, the sound output from the rear RCA and XLR jacks will be rerouted to the headphones and the volume will be automatically reduced as to not damage the headphones. Use the volume control on the IR remote or the volume slider within the control apps to adjust volume to the headphone. When headphones are disconnected from the headphone jack, the output volume will be restored to rear RCA and XLR jacks at the previous listen level prior to connecting the headphones.

1. Place the DMS-500/550/600 within a cable run of your router or Ethernet port of which is wired back to the router.
2. Connect an Ethernet cable to the back of the DMS-500/550/600 and plug the other end into your router, or Ethernet Port.
3. If connection isn't automatically established, Press Menu on the IR remote and navigate to Network Settings. Select Wired and DHCP (for automatic configuration) and press Connect. If you prefer assigning a manual IP address, select Static and enter your Port number and IP address. However, DHCP is the most common method. If you encounter issues connecting, try to reset network by selecting "RESET".

PROMPTED WIRELESS (WI-FI) SETUP

This step assumes you have an active wireless home network and router installed in your home.

NOTE: The quality and stability of the audio signal depends on the bandwidth and range of your WiFi router. This is especially true for exceptionally high-resolution files, such as DSD files or PCM files greater than 192kHz. When possible, a wired (Ethernet) connection is preferred.

1. Place the DMS-500/550/600 anywhere within the routers Wi-Fi range. Make sure BOTH Wi-Fi antenna are connected.
2. Turn on the DMS-500/550/600. Once on, press the Network Input Source on the IR remote. The following prompt will display. To connect to Wi-Fi, Press YES.

The DMS-500/550/600 are extremely versatile network audio component and can access/stream music in multiples ways. With respect to network audio the DMS-500/550/600 are a Client, meaning it finds and request playback of audio files from computer servers using its own custom apps for iOS and Android devices, or from its hand held IR remote control. It can also act as a Renderer, meaning you can push music to it from computer servers via third party DLNA/UPnP apps. The DMS-500/550/600 can also can play music from portable devices in a variety of ways, these include Qualcomm aptX™ HD Bluetooth, Airplay, and Phoneshare. This section will discuss each of these options.

NETWORK AUDIO SETUP

Make sure The DMS-500/550/600 are connected to your network either by a wired Ethernet connections, or via Wi-Fi as outlined in the Establishing a Network Connection section of this manual. This section assumes you are familiar with third party media server software, computers, file sharing settings, etc. As such, networked computers can either have server software of your preference running on them to "serve" files to the DMS-500/550/600 (Media Server), or the DMS-500/550/600 can use standard Service Message Block (SMB) file sharing protocol from Windows and Apple without running installed server software (PC Share), and the DMS-500/550/600 can also act as a Renderer. So, before going further make sure your media server software is installed and running on the server computer, and or all file sharing and permission settings for everyone are setup for your computer(s) and music folder, subfolders, etc.

Note: Window Media Player includes a server (Window Media Server). Using the Windows Media severely limits support for various file types and resolutions. It is not recommended, but will show up as an available server. We suggest using dedicated media server software, such as JRiver, Foobar2000, Media Monkey, etc., for the advanced user, and PC Share for the less advanced user. PC Share uses Service Message Block (SMB) protocol to communicate with a PC or MAC. This requires very little setup and no third party software. Even though PC Share is suggested for the less advanced user it is sometimes preferred due to easy setup and support for any file type or resolution. Using the DMS-500/550/600 as Renderer is also quite simple. However, the computer or app media player software one uses can affect playback.

Windows Media Server will display icons similar to these.

NETWORK CLIENT STREAMING AUDIO PLAYBACK

Network streaming allows the playback of digital music files stored on computers or NAS Drives connected to your network. The advantage of network streaming is you don't have to have the computer(s) or NAS Drive(s) located anywhere near the DMS-500/550/600 or your audio system. However, the computer(s) or NAS Drives must remain powered on for The DMS-500/550/600 or any network audio player to access them. The other advantage to network Client Streaming outside of using the IR hand held remote is that virtually all features of the DMS-500/550/600 can be accessed in one easy to use custom app.

1. Press the Network button on the IR remote. This will show a list of all available "PC Share" and or "Media Servers" on the network. The DMS-500/550/600 also lets you filter by PC Share or Media Servers by checking the associated box to the right of the list.
2. Navigate to your preferred Network source with the Up, down keys and select it by pressing Enter.
3. If you don't see the computer (PC Share) you are look for, you can manually add a PC Share by highlighting the Add button and pressing Enter. Type in the computer name (case sensitive) and any needed username and password. The new PC Share should now appear.

NOTE: When selecting a PC Share for the first time it must index the PC Share library. This can take a while depending on the size of the library. While indexing, you will see the following pop-up.

1. Navigate to your selections by using the Up and down keys. To expand the selection, press Enter or press > on the hand held remote to expand.

Notice the Hierarchy difference between a Media Server and PC Share Home Screens. The folder view(s) for media Servers are dependent on how your media server software is setup and configured on your computer. PC Share is set by the DMS as below.

Media Server	PC Share
NETWORK INPUT: Office PC Folders Playlists Queue	NETWORK INPUT: Family PC Artist Album Genre Composer All Tracks Folders Playlists Queue
NETWORK INPUT: Office PC Artist Artist_Albums All Albums All Track Playlists

1. Navigate to your desired music selection and press Play. You can also press the Play All when available to play all selections beneath it. Once playback is initiated, the Now Playing Screen will display as follows.

NOTE: You can also select Add or Delete from the IR remote to create a Queue or playlist. See Queue and Playlist section of the manual.

NETWORK RENDERER STREAMING AUDIO PLAYBACK

Using the DMS-500/550/600 as a Renderer is altogether different from the Client operation. This function requires server software to be installed on your server computer(s) as described above, and the use of a third party DLNA/UPnP app. The advantage for some is that they may prefer to use a different app instead of our custom DMS-500/550/600 apps. For example, one may prefer JRiver's JRemote or Gizmo, Bubble UPnP, Plug Player, 8Player, etc. The disadvantage is the third-party app can only play network audio but cannot access all features of the DMS-500/550/600 so a combination of a third-party app and IR remote must be used in conjunction. Renderer operations is very simple as outlined below.

1. Turn on the DMS-500/550/600. It does NOT matter what inputs source the DMS-500/550/600 are set to.
2. Open your preferred third party DLNA/UPnP.
3. Select "CARY DMS-500/550/600" from the available renderers within the third-party app and initiate playback in accordance to the third-party app.
4. The Now Playing screen will display your selection. All music selections and playback can only be controlled by the third-party app.

Another way to push music to the DMS-500/550/600 in renderer mode is with or from a computer. To do so follow these steps;

1. Turn on the DMS-500/550/600. It does NOT matter what inputs source the DMS-500/550/600 are set to.
2. Turn on your computer (Preferably Windows 7 or MAC OS X or latter) and open your preferred media player software.
3. Right click on a music selection and Send to/Cast to Cary DMS-500/550/600 right from the computer. See example below. Function may vary depending on media player software being used.

The DMS-500/550/600 can play music from phones and tablets in several ways. These methods include Airplay, Phoneshare, and Bluetooth. Airplay and PhoneShare operate via the same method although AirPlay is mostly for iOS devices and PhoneShare for Android devices.

AIRPLAY AND PHONESHARE PLAYBACK AND CONNECTION

Airplay is primarily for iOS devices while PhoneShare is for Android devices. They both require a wireless connection of your portable device to your network and sends music from your device to your router over Wi-Fi and the router sends it to the DMS-500/550/600 either Wi-Fi or wired Ethernet, depending on how your DMS-500/550/600 are connected to your network router. The advantages of AirPlay and PhoneShare is that since it relies on Wi-Fi the range of which you can send music to the DMS-500/550/600 from your portable device is much greater than Bluetooth.

(1) Open your desired music app and look for this icon ▲
(2) Tap on the icon and wait for available device(s) to appear.
(3) Select "Cary DMS-500/550/600" and start playback of your music selection.
(4) The DMS-500/550/600 will display all track information including artwork on the front panel.

NOTE: To get the most of Airplay or PhoneShare during playback you can utilize our TruBit™ PCM and DSD Upsampling for a superior listening experience of these sources.

BLUETOOTH CONNECTION

Bluetooth can work for both iOS and Android devices. The advantage of Bluetooth is it's a point to point signal, meaning no Wi-Fi or router connection is required to work. However, the range of Bluetooth is much shorter

Qualcomm aptX™ HD Bluetooth audio is capable 24 Bit / 48 kHz better-than-CD quality audio with the DMS-550-600 and CD quality 16 Bit / 44.1 kHz with the DMS-500 when using Bluetooth device capable of aptX™ and aptX™ HD. For more information, please visit Qualcomm's web site at https://www.aptx.com/aptx-hd.

Pairing a device with the DMS-500/550/600

When connecting a Bluetooth device to the unit for the first time, you must "pair" it to the DMS-500/550/600. Once pairing is completed, subsequent connection can be made with a couple of easy steps.

Initial Pairing Steps

1. Select the BLUETOOTH input on the DMS-500/550/600 and the display will show as follows;

1. Go to the "Settings" of your portable device and find Bluetooth settings and make sure Bluetooth function is ON and in search mode.

2. "CARY DMS-500/550/600" should appear on your portable device as a Bluetooth receiver. Once it does, select it.

1. After pairing is complete, the display of DMS-500/550/600 will show as follows;

1. The display of the DMS-500/550/600 will show as follows once you initiate playback rom your portable device.

NOTE: If pairing information is deleted from your device, you will need to perform pairing of that device again in order to connect.

NOTE: Artwork for Bluetooth playback does NOT come from your Bluetooth Source. It is found online in accordance with the files tagging and online database. It is possible your Bluetooth source and the DMS-500/550/600's display screen can show varying degrees of matching artwork.

BLUETOOTH PLAYBACK

Once pairing has successfully been completed, you can easily enjoy music from your portable devices as follows.

(5) Select the BLUETOOTH input on the DMS-500/550/600 front panel or on the hand held remote.
(6) Double check your device Bluetooth setting and make sure "CARY DMS-500/550/600" is selected.
(7) Begin playback of music on your device, which can include stored music files or music apps.
(8) If you see a "play to" icon; ▲ in your music app, tap it and select "CARY DMS-500/550/600" to ensure the signal is playing to the DMS-500/550/600.

NOTE: To get the most of our fi^™ Bluetooth Implementation during playback you can utilize our TruBit ^™ PCM and DSD Upsampling for a superior listening experience of Bluetooth sources.

BLUETOOTH OUTPUT (DMS-600 ONLY)

Use this feature to send the audio signal via Bluetooth to a set of Bluetooth headphones or Bluetooth speakers.

1. Set your Bluetooth headphones or speaker to paring mode.
2. Go to Menu>>Bluetooth Send. Switch to ON. DMS-600 will search for Bluetooth devices and list them.

1. Scroll down to highlight desired Bluetooth device and press Enter to connect.

PCM TO DSD CONVERSION

Through use of our TruBit™ Upsampling technology as described below, it is now possible to convert PCM files to DSD. For those that prefer DSD this is an extremely powerful feature. Imagine taking any source or sample rate from network, internet, Bluetooth, AirPlay, or SPDIF and converting to DSD64, 128 or 256. Whether you're in the PCM or DSD camp, The DMS-500/550/600 accommodates both! Not only can you convert any PCM sample rate up to 768 kHz in the PCM domain, but TruBit™ Upsampling also allows you to convert that 16, 24 bit PCM to a 1 bit direct stream digital signal with sample rates of 2.8224 MHz (64 or standard rate), 5.6448 MHz (128 or Double rate), 11.2 MHz (256 or Quad rate). You can even up convert a native DSD64 file to a higher level of DSD128 or DSD256. By using superior no compromise AKM DAC's, any native DSD or PCM to DSD converted signal is processed as true DSD. In other words, The DMS-500/550/600 does NOT down convert a DSD signal to PCM within the DAC chips. This is actually somewhat rare as many so called DSD players actually down convert the DSD signal to PCM inside the inferior DAC chip(s) without you knowing it.

PCM AND DSD UPSAMPLING

TruBit™ Upsampling is a powerful upsampling technology used to upsample lower sample rates to higher sample rate and increases the bit depth to 32 bits for PCM and 1 Bit for DSD in the digital domain via a dedicated 128 bit DSP engine prior to analog conversion. This can be very useful in achieving a more enjoyable listening experience. Once a native input signal is changed to a selected higher sample rate, the bit depth will also automatically increase to 32 bits for PCM or change to 1 bit for DSD conversion. However, like all-powerful tools, this too should be used prudently. We do not take a blanket "higher is better" approach to upsampling. It is important to experiment with different rates depending on your source or source material. Many times a native rate might be preferred whereas some recordings or files formats might benefit from a higher sampling rate, and so on.

The available selectable sample rates depend on the input signals original sample rate. For example, above 192 kHz the available PCM rate(s) will only be in multiples of either 44.1 kHz or 48 kHz as follows:

Input signal rates of 44.1 or multiples of:

BYPASS (44.1) ---> 48 ---> 88.2 ---> 96---> 176.4 ---> 192 ---> 352.8---> 705.6
---> DSD64 ---> DSD128 ---> DSD256. 

Input signal rates of 48 or multiples of:

BYPASS (44.1) ---> 48 ---> 88.2 ---> 96---> 176.4 ---> 192 ---> 384--->768
---> DSD64 ---> DSD128 ---> DSD256. 

Pressing the "SRC" button on the hand held remote will cycle through the available sample rates.

• "BYPASS" next to Upsample Rate means The DMS-500/550/600 will pass the input signal rate out in its native rate without any upsampling.
• When an upsample rate is selected higher than the native input rate, the DMS-500/550/600 will upsample all incoming rates lower than the selected upsample rate up to the selected upsample rate (as well as change the bit depth to 32 bits for PCM or 1 bit for DSD). Any signals played that are equal to or higher than the selected upsample rate will playback unchanged as evident by the displays "Upsample Rate" showing "BYPASS" or the same upsample rate as the input rate. Subsequent playback of lower input rates behave as described above. Each of the DMS-500/550/600 inputs will remember the upsample rate as set for that input.

NOTE: Anytime an upsample rate is selected, the bit depth will change to purple signifying the bit depth conversion from its native rate to either 32-Bit for PCM upsampling, or 1-Bit for PCM to DSD conversion.

DSD PLAYBACK

The DMS-500/550/600 are capable of playing native (not just DoP) DSD files up to 512 via both wired Ethernet and wireless Wi-Fi inputs as well as from the USB/SD inputs. If using Wi-Fi as your network connection, it is recommended to use a 5 GHz router and have a very robust signal at the DMS-500/550/600 location. You can also choose to access a computer that is connected wirelessly to your network as well.

However, this adds another potential interruption in the signal path when playing large files, such as DSD, etc. For the fastest and most reliable playback, a wired Ethernet connected is recommend to both the DMS-500/550/600 as well as to your computer(s).

NOTE: When playing DSD files The DMS-500/550/600 will not output from the SPDIF outputs being we do not convert DSD to PMC and that SPDIF outputs are limited to 24 bit – 192kHz PMC output.

MQA PLAYBACK NOTIFICATION

MQA

The DMS-500/550/600 are the first product to earn MQA certification using MQA's 16x rendering. This means the MQA files will play at a fixed sample rate of 705.6 kHz or 768 kHz. Upon Playback of an MQA encoded file,

'MQA' (Green Dot), 'MQA Studio' (Blue dot), 'MQA Core' (Magenta dot) indicates that the unit is decoding and playing an MQA file.

MQA Studio indicates the file has either been approved in the studio by the artist/producer or has been verified by the copyright owner as provenance to what was heard in the studio.

MQA Green indicates a file that has been MQA encoded without provenance.

MQA Magenta indicates the MQA file's first unfold was decoded by software (only up to 88.2 kHz or 96 kHz), such as Roon or Audirvana, and the rest decoded by the full hardware decoder within the DMS-500/550/600. Core decoding can be turned off in the third-party software program to allow all decoding to be done by the DMS-500/550/600.

Ethernet, Wi-Fi, USB-A, and SD Card inputs are all capable of MQA playback. SPDIF inputs of the DMS-500/550/600 are not capable of MQA playback. Additionally, when playing MQA files the optical and coaxial outputs will NOT pass through any signal.

ROON OVERVIEW

The DMS-500/550/600 are a Roon Ready Certified endpoint. This means if you subscribe to Roon and have the Roon Core software installed on your PC or MAC, you can use the Roon tablet or Phone app to playback music from your network storage to the DMS-500/550/600. When you use the Roon ecosystem for playback, your control of the

DMS-500/550/600 are limited to the Roon apps ability. For example, you can turn The DMS-500/550/600 on or off from the Roon app and control volume options as well as any other Roon integrated feature, such as TIDAL. However, all other DMS-500/550/600 features are only accessible from the DMS-500/550/600 IR or app remotes.

ROON SETUP

To enable "Roon Ready" from the DMS-500/550/600, press Menu and scroll down to Roon Ready. Select Enable as shown below, then exit.

This can also be done from the DMS-500/550/600 control app via navigating to Settings>>Roon Ready>>Enable.

Before proceeding you must downloaded and install the Roon Core software on your computer (https://roonlabs.com/downloads.html) and setup your library monitoring and other personal preferences within the Roon Core software. Below details how to enable The DMS-500/550/600 as a Roon Ready endpoint within Roon Core.

1. In Roon Core software, select Settings, then Audio.
2. Scroll down to the "Networked" section. You should see the DMS-500/550/600 listed.
3. Once the DMS-500/550/600 are listed, it will show a blue "Enable" box. If not, turn on the DMS-500/550/600 first.

1. Once you click on "Enable" it will ask for the name the Zone

1. You'll notice the Setting icon next to an enabled Roon Rady device. Initially, you can leave the Roon Core settings for the DMS-500/550/600 in their default setting. Pressing DSP Engine will take you to DSP Setting.

1. This shows how to disable the DSP setting in Roon. A word on DSP setting in Roon. The DMS-500/550/600 are already capable of playing extremely high resolution PCM, MQA, and DSD without the need for additional DSP setting. If you enable DSP in Roon, please use these setting carefully.

1. In addition to DSP settings, Roon also has a Device Setup section, specific to the playback device. There are two ways to access this. One, in the Audio Setup page (left graphic). Two, in the now playing screen by pressing the "Signal Path" light, then the 3-Dot menu next the Roon Ready endpoint product name (right graphic).

1. in Device Setup, there are multi areas to look at. However, Roon usually presets these based on the capabilities of the playback device. It primarily focuses on how MQA files are handled as well as sample rate and bit depth capabilities of the playback device.

Roon Defaults the DMS-500/550/600 as both an MQA Decoder and Renderer, but you could select Decoder Only to not allow Roon Core to decode MQA at all. However, Decoder and Renderer is perfectly fine.

You Could also set the DMS-500/550/600 as a Renderer only which mean Roon Core will always do the first MQA unfolding instead of the DMS-500/550/600. The DMS-500/550/600 will then do the rest of the MQA unfolding/rendering

Also, be sure to set as follows for the max sample, bit, and DSD rate the DMS-500/550/600 are capable as shown below. You can also override any Roon MQA decoding by turning Enable MQA Core Decoding off.

When the DMS-500/550/600 are set as a decoder only, you can see from the signal path that ONLY the DMS-500/550/600 are fully decoding the MQA file to its fullest resolution without any rendering. This is a Preferred method.

When the DMS-500/550/600 are set as a renderer, you can see from the signal path there are now two-steps to the MQA decoding process. First the Roon Core software will decode the first unfold, then the DMS will render the second and third unfolding. For most circumstances, this is not necessary, and it would be better to let the DMS-500/550/600 decode the full MQA signal.

Enabling Roon MQA Core decoding is only needed if you are using Roon DSP to process the signal before it reaches the DMS-500/550/600, then Roon will want to handle the first MQA unfolding so that whatever DSP you are using can be applied.

After completing the above steps of enabling the DMS-500/550/600 Roon Ready capability and downloading, installing, setting up the Roon Core computer software, you can follow the below steps to playback music files via the Roon Ecosystem.

1. Open the Roon tablet or phone app.
2. Press the Select an Audio Zone.

1. Select the DMS-500/550/600 as the desired zone and Press the Sound Icon which will reveal a drop-down box.

1. In this box is a Power Button Icon. Press it to reveal the DMS-500/550/600 button. Press it and DMS-500/550/600 should power.

1. Once DMS-500/550/600 if fully powered up and ready to go, you can simply browse the Roon App interface to select any music you wish. Once you select Play it will send the music to the DMS-500/550/600 via a bit-perfect stream of data. The first time you do this, you may have to adjust the Roon volume slider accordingly.

Master Quality Authenticated (MQA)

The DMS-500/550/600 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. This ensures that MQA-encoded audio files and streams sound exactly like the source. 'MQA' (Green Dot) indicates that the unit is decoding and playing an MQA stream. 'MQA' (Magenta Dot) indicates that the unit is receiving an MQA signal by Core decoding outside the unit. 'MQA Studio' (Blue dot) denotes provenance to ensure that the file and sound is approved by the artist, producer, and or original engineer.

CARE AND CLEANING

The cabinet housing and front panel of the DMS-500/550/600 and DMS-500/550/600 may be cleaned with a soft cloth and Windex or a window cleaner. The frequency of cleaning will be governed by how many hours the DMS-500/550/600 are operated and by operating environment cleanliness.

CAUTION:

- Do not let any liquids spill into the vents on top of the unit.

AC POWER FUSE REPLACEMENT

The fuse is located inside the chassis and is not user serviceable. If the unit does not power up, contact an authorized service representative. Never replace the fuse with any other value than a two (2) amp slow blow fuse 250V. The AC Power Cord must be unplugged from the AC Power jack on the back of the unit prior to replacing the fuse. Set the unit Power On/Off switch to the Off position and plug the AC Power cord back into the AC Power jack. Then set the Power On/Off switch to the On position and verify proper operation. Contact Cary Audio for advice if the fuse repeatedly blows.

DO NOT return the DMS-500/550/600 to the factory without a Return Merchandise Authorization (RMA) number from our online Customer Service Center (www.caryaudio.com).

Please retain and always use the original shipping carton for shipping the player. Also, Cary Audio reserves the right to return products sent in for service in a new box set at the customer's expense if the original packing material was damaged in the initial shipment, or if it is deemed unsatisfactory to use in return shipping.

Because Cary Audio cannot control the providers of such services or the services themselves, the owner of the Product therefore assumes all risks related to the use of services provided by anyone other than Cary Audio itself. Cary Audio cannot and does not warrant against, and shall have no liability of any kind for any of the following that are attributable to non-Cary Audio providers or services: (1) interruption, discontinuance, or other unsatisfactory performance of service, (2) reduced Product functionality that is so attributable, or (3) any other loss or damage of any kind that is so attributable.

All implied warranties, including warranties of merchantability and fitness for particular purpose, are limited in duration to the length of this warranty.

Exclusion of Damages

Cary Audio's liability for any defective product is limited to repair or replacement of the product at Cary Audio's option. Cary Audio shall not be liable for damage to other products caused by any defects in Cary Audio products, damages based upon inconvenience or loss of use of the product or any other damages, whether incidental, consequential, or otherwise.

How State Law Relates to the Warranty

Some states do not allow limitations on how long an implied warranty lasts and/or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you.
