WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THE XDA-3 NEAR WATER OR IN WET LOCATIONS, DO NOT EXPOSE IT TO RAIN OR MOISTURE, DO NOT EXPOSE IT TO DRIPPING OR SPLASHING FROM OTHER SOURCES, AND ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS (SUCH AS VASES) ARE PLACED ON IT. DOING SO MAY RESULT IN DAMAGE TO THE UNIT AND THE RISK OF ELECTRIC SHOCK, WHICH MAY RESULT IN BODILY INJURY OR DEATH.

WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER FROM THE XDA-3. THERE ARE NO USER-SERVICEABLE PARTS INSIDE THE UNIT. REFER ALL SERVICE TO QUALIFIED SERVICE PERSONNEL.

Do not install the XDA-3 near or above any heat sources such as radiators, heating vents, or other apparatus that produces heat. Do not block any ventilation openings or heat sinks. Avoid installing the unit directly above other heat-producing equipment unless sufficient ventilation or forced-air cooling is provided.

Do not install the XDA-3 in locations without proper ventilation. The XDA-3 itself produces very little heat, but the top panel will still get warm and requires some clearance for air flow. The unit should not be installed in an enclosed location such as a bookcase, cabinet, or closed equipment rack with other equipment that will produce excessive heat unless sufficient forced-air ventilation is provided.

Always install your XDA-3 according to the manufacturer’s instructions and only use attachments or accessories specified by the manufacturer.

Do not install the XDA-3 on any stand, shelf, or other piece of furniture that is unable to support its weight. If a cart is used to move the unit, use caution to avoid injury from tip-over.

Connect the XDA-3 only to power sources of the correct voltage (as shown in this manual and on the XDA-3 unit).

Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially careful where the power cable enters the power outlet and the unit.

Only connect the XDA-3 to an electrical outlet or extension cord of appropriate type and rating.

DO NOT defeat the safety purpose of a grounding or polarized plug by removing ground pins or using unsafe adapters. A polarized plug has two blades – one wider than the other. A grounding plug has a third ground prong in addition to the two main conductors. The wide blade or third groundling prong is provided for your safety. If the provided plug does not fit your outlet, consult an electrician to replace your obsolete outlet. If you replace the power cord, only use one of similar type and equal or greater current rating.

The power cable for the XDA-3 should be unplugged from the outlet during severe electrical storms, or when unused for a long period of time.

Only replace the fuse(s) in the XDA-3 with fuse(s) of proper value and voltage rating.

The XDA-3 should only be cleaned as directed in the manual. Avoid spraying liquids directly onto the unit. Do not insert or allow small parts or hardware to fall into the connectors on the unit.

You should seek service for your XDA-3 by qualified service personnel if any of the following occur:

1. The power-supply cord or the plug has been damaged.
2. Objects or liquid have fallen or spilled into the unit.
3. The unit has been exposed to rain.
4. The unit exhibits a marked change in performance.
5. The unit has been dropped, or its enclosure or chassis is damaged.

Introduction

Thank you for purchasing the new Emotiva XDA-3 Differential Reference DAC.

The XDA-3 Differential Reference DAC is a lot more than just a superb audiophile quality digital-toanalog converter. The XDA-3 is also a fully capable audiophile preamp and control center, with both digital and analog inputs, an HDMI ARC input that can accept a digital audio signal directly from your TV, a real analog ladder network volume control, and a high-performance super-low-distortion headphone amplifier.

The XDA-3 has a variety of standard digital audio inputs, including two optical (Toslink) S/PDIF inputs, two electrical (Coax) S/PDIF inputs, and one high performance USB digital audio input. The USB input on the XDA-3 accepts stereo PCM digital audio at bit depths and sample rates up to 32/768k, DSD digital audio in the DoP format up to DSD256, and DSD digital audio in the native DSD format up to DSD512. The HDMI-ARC input accepts a digital audio signal directly from your TV, which enables the XDA-3 to play audio from TV apps, and from other HDMI sources connected to your TV. The XDA-3 also includes two pairs of stereo line level analog inputs, one balanced and one unbalanced, which you can use to connect analog source devices like a phono preamp or portable music player.

Digital audio received by the XDA-3 is converted into analog by an audiophile quality ESS ES9038Q2M SABRE32 Reference DAC chip and its associated precision power supply and reference circuitry. The fully balanced fully differential analog output from the DAC is then routed to the digitally controlled analog ladder network volume control, and then to the balanced outputs, via OPA1656 low-distortion ultra-low-noise op amps. A separate balanced-to-unbalanced converter stage derives the unbalanced output signal for the RCA outputs directly from the fully differential output signal. The XDA-3 offers a choice of seven user selectable oversampling filters, each of which offers a subtly different listening experience, and which can be accessed directly from the remote control. Analog inputs to the XDA-3 are routed directly to the output, via precision buffer circuitry, and the analog ladder network volume control, and always remain in the analog domain.

The XDA-3 also includes a high-quality current feedback headphone amplifier which offers superb performance and incredibly low distortion. An attractive, fully dimmable, blue OLED display shows the current Volume setting and Input choice, as well as the sample rate and format of the incoming audio signal. The display switches momentarily to show additional information when the format of the incoming audio signal changes or you change the selected oversampling filter. In addition to the display, the front panel of the XDA-3 includes separate buttons for changing Inputs, adjusting the Volume, and toggling Standby mode, and a convenient full-sized 1/4” stereo headphone output.

The full function machined aluminum remote control offers separate buttons for selecting each input individually, controlling volume and muting, adjusting the display brightness, and displaying or changing the selected oversampling filter.

We designed the XDA-3 from the ground up to deliver the same superb listening experience with both digital and analog sources… either as a source component or as a fully capable digital and analog preamp and control center. We hope you enjoy using your XDA-3 as much as we enjoyed designing and perfecting it.

Happy Listening!

XDA-3 Front Panel

1. Headphone Jack (1/4”)
   The XDA-3 includes a monolithic high performance current feedback headphone amplifier with wide dynamic range and exceptionally low noise and distortion. When there are headphones plugged into this jack, the main outputs are muted, and the Volume buttons on the front panel (and on the remote control) adjust the headphone output level.

2. Input Selector Buttons
   Press either of the Input Selector buttons to cycle the XDA-3 through its available inputs. Each Input is momentarily displayed full-screen on the front panel OLED display as it is selected.
   (The Input buttons on the remote control switch directly to each input.)

3. Front Panel Display (Alphanumeric OLED Display)
   The easy to read alphanumeric OLED display on the front panel of the XDA-3 normally displays the Volume setting, the selected Input, and the sample rate of the incoming audio signal. It switches to a more focused single-mode display when relevant information is available. For example, when you change Volume, a full screen Volume bar is displayed and, when you select an Input, the name of that Input is displayed full screen. The brightness of this display can be adjusted by using the Dim button on the remote control.

4. Volume Up and Volume Down Buttons
   Press the Volume Up and Volume Down buttons to raise and lower the Volume on the XDA-3. A single press moves the Volume one step, holding the button causes the Volume to continuously move smoothly up or down. When there are headphones plugged in, the Volume buttons on the front panel (and on the remote control) adjust the headphone output level. When no headphones are plugged in, the Volume buttons adjust the main output level. Both settings are stored independently.
   Volume control for both digital and analog audio inputs is via a precision digitally controlled analog resistor ladder network, which moves in precise 0.5 dB steps, and ensures absolute repeatability and near-perfect channel matching at all Volume settings. Unlike digital volume controls, the XDA-3’s analog volume control doesn’t reduce bit depth, nor introduce grain or distortion, at low volume settings.

5. Standby Button and Standby Indicator
   When the rear panel AC Power switch is On, press this button to switch the XDA-3 On; press it again to return to Standby. You may also switch the XDA-3 On and Off using the On and Standby buttons on the remote control.

Note: When the XDA-3 is in Standby Mode the Standby Indicator will be illuminated AMBER. When the XDA-3 is On the Standby Indicator will NOT be lit.

Note: The rear panel AC Power switch must be on for the XDA-3 to operate. If the rear panel AC Power switch is Off, the XDA-3 will not respond to either the front panel controls or the remote control.

XDA-3 Remote Control

The solid aluminum full-function remote control for the XDA-3 includes several functions that are not included in the front panel controls, including the Mute, Dim, and Filter buttons, as well as buttons that enable you to directly select Inputs.

Standby & On Buttons

Press the On button to turn the XDA-3 On from Standby Mode.
Press the Standby button to return the XDA-3 to Standby Mode.
Note: The rear panel AC Power switch must be On for the XDA-3 to operate. If the rear panel AC power switch is Off, the XDA-3 will not respond to either the front panel controls or the remote control.

Filters Button

The Sabre ES9038Q2M DAC includes a choice of seven user-selectable oversampling filters, each of which delivers a subtly different user listening experience. The first time you press the Filters button it will display the number of the currently selected Filter. Pressing the Filters button repeatedly while the Filter Number is displayed will cycle through the available filters.
To select a Filter simply stop pressing the button when the desired Filter Number is displayed and wait a few seconds.

Dim Button

Press the Dim button once to see the current Brightness setting.
Pressing the Dim button repeatedly will cycle through the available Brightness settings. To select a Brightness setting simply stop pressing the button when the desired setting is displayed and wait a few seconds.

Note: The front panel display and LEDs will be fully off with the Brightness set to 0. The maximum Brightness setting is 10.

Volume (+) & Volume (-) Button

Press the Volume (+) and Volume (-) buttons to raise and lower the Volume. A single press moves the Volume one step, holding the button causes the Volume to continuously move smoothly up or down. When there are headphones plugged in, the Volume buttons on the front panel (and on the remote control) adjust the headphone output level. When no headphones are plugged in, the Volume buttons adjust the main output level. Both settings are stored independently.
Volume control for both digital and analog audio inputs is via a precision digitally controlled analog resistor ladder network, which moves in precise 0.5 dB steps, and ensures absolute repeatability and near-perfect channel matching at all Volume settings. Unlike digital volume controls, the XDA-3’s analog volume control doesn’t reduce bit depth, nor introduce grain or distortion, at low volume settings.

Note: If the XDA-3 is in Mute Mode pressing the Volume (+) button will toggle Mute Off.

Inputs (Direct Select)

Press any of these buttons to directly select the Input of your choice.

• CO1 – Coax (electrical S/PDIF) Digital Audio Input (#1)

• OPT2 – Toslink (optical S/PDIF) Digital Audio Input (#2)
• USB – USB Digital Audio Input
• ARC – ARC (TV audio return channel) Digital Audio Input
• RCA – Unbalanced Analog Audio Input
• BAL – Balanced (XLR) Analog Audio Input

XDA-3 Rear Panel

1. Balanced (Analog) Inputs
   Connect any stereo balanced analog audio source to these Inputs.

2. Unbalanced (Analog) Inputs
   Connect any stereo unbalanced analog audio source to these Inputs.

3. Balanced & Unbalanced (Analog) Outputs
   Connect these outputs to a set of balanced or unbalanced inputs on your preamp if you want to use the XDA-3 as a DAC or source component. Connect them directly to your power amplifier if you want to use the XDA-3 as a high performance DAC and preamplifier / control center.
   Note: Both Balanced and Unbalanced outputs are active at the same time. The level of both sets of outputs is controlled by the Volume and Mute controls.
   Note: The main outputs are muted when headphones are plugged into the front panel. When there are headphones plugged in, the Volume buttons on the front panel (and on the remote control) adjust the headphone output level. When no headphones are plugged in, the Volume buttons adjust the main output level. The XDA-3 stores both settings independently. When you unplug the headphones, the main output level will return to its previous setting; when you plug the headphones back in, they will return to their previous setting.

4. USB (Digital) Input
   Connect your computer or other similar digital audio source to this input. Your computer or source device will recognize the XDA-3 as a USB Audio Class 2 (UAC2) compliant “USB audio output device” or “external USB DAC”. (Some source devices may identify the XDA-3 as “Emotiva XDA-3”. Others may report it as “SXW CTUAD768 PRM-A”, which is the name of the high performance audio interface chip we use. And, if you’ve installed special drivers, it may be identified by the driver or drivers you’ve chosen to use.)
   See the section entitled Using The USB Input for more details.

5. HDMI ARC (Digital) Input
   Use this input to connect the XDA-3 to the ARC (Audio Return Channel) output of a TV set or projector. The XDA-3 is a STEREO DAC and so will only accept a stereo audio input.
   See the section entitled Using The HDMI ARC Input for more details.
   Note: The HDMI-ARC connection on your TV is intended to deliver a digital audio OUTPUT to an AVR or preamp/processor when the audio source is either an App running on your TV or a device connected directly to one of the other inputs on your TV. HOWEVER, EVEN THOUGH YOU WILL BE USING THE HDMI-ARC CONNECTION ON YOUR TV TO OUTPUT A DIGITAL AUDIO SIGNAL, BECAUSE THAT CONNECTION IS ALSO NORMALLY USED TO INPUT A VIDEO SIGNAL TO THE TV, IT WILL BE LABELED ON YOUR TV AS AN “HDMI-CEC INPUT” or “HDMI/ARC INPUT”.
   Note: The HDMI-ARC connection between your TV and the XDA-3 uses an ordinary HDMI cable.
   This connection does not require a high speed HDMI cable. HOWEVER, BE SURE TO USE AN HDMI CABLE THAT INCLUDES AN ARC CONNECTION, WHICH VIRTUALLY ALL MODERN HDMI CABLES INCLUDE. IF YOU PLAN TO USE A SPECIAL POWERED HDMI CABLE OR OTHER TYPE OF HDMI EXTENDER, BE SURE THAT IT ALSO SUPPORTS ARC. ALSO NOTE THAT, WHILE WE EXPECT HDMI-ARC ON THE XDA-3 TO WORK WITH MOST POWERED CABLES AND EXTENDERS THAT SUPPORT ARC, WE CANNOT PROMISE THAT IT WILL, AND CANNOT PROVIDE SUPPORT IF YOU ARE UNABLE TO GET IT TO WORK.

6. Optical 1 & Optical 2 Toslink Optical S/PDIF (Digital) Inputs
   Coaxial 1 & Coaxial 2 Electrical S/PDIF (Digital) Inputs
   These inputs accept optical S/PDIF (Toslink) and electrical S/PDIF (Coax) digital audio signals, in stereo PCM format, at sample rates up to 192k and bit depths up to 24 bits.
   Note: The XDA-3 is a stereo PCM DAC and only accepts STEREO PCM digital audio signals. The XDA-3 CANNOT decode DTS, Dolby Digital, or other surround sound audio formats.
   Note: For computer-based sources, or other source devices that support either higher sample rates, or other formats like DSD, use the USB Digital Audio input.
   Note: If you attempt to play DTS-encoded audio files on some equipment that doesn’t recognize DTS encoding, the undecoded DTS audio files may be sent to the XDA-3, which may result in an unpleasant digital screeching noise. (This will not harm anything, but suggests that your source equipment either cannot properly process DTS-encoded files, or is not configured correctly to do so.)

7. Trigger Input & Trigger Output
   The Trigger Input will enable the XDA-3 to be turned on by a trigger signal from another piece of trigger-enabled gear. The Trigger Output on the XDA-3 will enable the XDA-3 to turn on other trigger-enabled gear. The Trigger Output on the XDA-3 is active when the XDA-3 is On.
   Note: The XDA-3 can only be turned on by a trigger signal if it is in Standby Mode. The XDA-3 will NOT respond to a trigger signal if the rear panel AC Power Switch is Off.

8. IEC Power Cord Receptacle
   Accepts a standard IEC power cable. A high quality commercial power cord is provided with the XDA-3.

9. AC Power Switch
   Switches the main AC power to the XDA-3 On and Off. When this switch is Off, no controls operate, and the XDA-3 cannot be turned On by the remote control or a trigger signal.

Quick Start

To get the most from your XDA-3, we urge you to read the entire manual. If you just can’t wait to listen to it, this section will cover the basics you need to get started.

• Find a secure location for your XDA-3.
• Connect your XDA-3 to one or more digital audio sources.
• Connect the analog output of your XDA-3 to a line level input on your preamp, or directly to your power amp.
• Find some music you really like to listen to.
• Turn on the AC Power switch and turn up the volume a bit!
• Enjoy!

Note: The USB input on the XDA-3 will work, without additional drivers, on both current Windows and Apple computers, as well as many smart phones and other source devices. However, you will probably have to configure your source device to support anything beyond its default sample rate, or to support audio formats other than PCM.

Using The USB Input

The USB Input on the XDA-3 is intended for connecting a computer or other computer-based digital audio source. The USB input on the XDA-3 will be recognized by the computer or source device as a standard USB Audio Class 2 external DAC or sound card, and supports PCM playback at bit depths and sample rates up to 32/768k, without the need to install any additional drivers. The XDA-3 will show up on your list of output devices as either Emotiva XDA-3 or SXW CTUAD768 (the high performance USB hardware in the XDA-3).

The XDA-3 also supports playback of DSD audio files via USB. The XDA-3 supports DoP-via-USB at rates up to DoP256 and native-DSD at rates up to DSD512. Additional ASIO drivers, which we provide, must be installed in order to support playback of DSD files on Microsoft Windows. Some player programs for Apple computers reportedly include internal support for one or both of these
options as well.

Note: The USB input on the XDA-3 will work, without additional drivers, on both current Windows and Apple computers, as well as many smart phones and other source devices, and supports PCM at sample rates up to and including 32/768k. However, by default, both Windows and Apple computers resample any digital audio they play to a preset default sample rate. Many higher quality player programs offer ways to bypass this resampling but each has specific settings and configuration options to do so.

Note: The XDA-3 supports true DSD playback via USB using two different methods:
“DoP” and “native DSD”. Both of these methods are ways in which a DSD digital audio stream can be encapsulated and sent to the DAC via a PCM audio stream over USB. Both deliver an identical bit-perfect copy of the original DSD digital audio stream. (Native DSD uses packet bandwidth somewhat more efficiently and so permits a slightly higher DSD sample rate to be supported over a given connection.)

DoP, which is the more standard method, is supported by many high quality player programs.
In order to use DoP on Windows computers, you must install the ASIO drivers, which we provide. Some Apple player programs also support DoP, with the necessary driver support being provided internally by the computer.

Native DSD, which is really a variant of DoP, is more complex, and may require additional settings or additional software. (For example, in FooBar2000, a separate proxy converter program must be installed and configured in addition to the ASIO driver and support required to support the standard DoP format.)

Note: By default both Microsoft Windows and Apple computers use PCM as their preferred format for sending audio data to a DAC. In addition to this, some programs, when specifically configured to do so, can send DSD directly to the DAC. However, when you play other types of encoded or compressed audio files, like FLAC, or ALAC, or MP3, or AAC, the file is first decoded by the player program, then sent to the DAC as PCM (or DSD). Therefore, you have no need to worry about whether your DAC supports a specific file format, as long as your player program supports it.

Note: The USB Input on the XDA-3 will appear to your computer or other source component as an external DAC or sound card. The XDA-3 CANNOT play audio files directly from a USB stick. Note: If you play MQA files, or MQA encoded audio from streaming sources like Tidal, the important “first unfold” is usually performed by your player program. The XDA-3 is neither “an MQA renderer” nor “an MQA decoder”. However you will find that MQA files that are unfolded by the player client, for example tracks that you play on Tidal using the Tidal client, will still sound excellent when played through the XDA-3.

WHILE WE CANNOT OFFER DETAILED SUPPORT FOR EVERY SOURCE DEVICE OR COMPUTER YOU MAY CHOOSE TO USE WITH THE XDA-3, WE WILL BE HAPPY TO OFFER YOU SUPPORT FOR CONFIGURING AND ENJOYING YOUR XDA-3, AND AS MUCH SUPPORT AS WE CAN REGARDING HOW TO CONFIGURE VARIOUS PLAYER PROGRAMS TO WORK WITH IT. WE HAVE ALLOCATED ROOM ON OUR SERVERS FOR A COLLECTION OF RESOURCES ABOUT HOW TO USE YOUR XDA-3 WITH VARIOUS SOURCES, PLAYER PROGRAMS, AND OTHER DEVICES. THIS LOCATION WILL ALSO BE A REPOSITORY FOR THE CURRENT ASIO DRIVERS FOR THE XDA-3.

We also expect to start a section on our forum, The Emotiva Lounge, dedicated to both the XDA-3, and to various resources and sources for high quality music.

Using The HDMI-ARC Input

The Audio Return Channel (HDMI-ARC) is a feature that is available on virtually all modern TV sets.
ARC is also currently available on one or two projectors and will probably be available on more projectors in the near future. It is important that you understand how HDMI-ARC works before using it to connect your XDA-3 to your television set.

Before smart TVs became popular, when a system included a TV or projector and an AVR or preamp/processor, the various sources were connected to the AVR or processor, and the output of the AVR or processor was then connected to an input on the TV. The AVR or processor then intercepted the incoming audio/video signal, extracted the audio portion of the signal, which it then processed and played, and passed the remaining video signal to the display.

However, with modern smart TVs, we often encounter situations where the audio portion of the signal originates in the TV itself. This is the case when you are watching programming that originates with a streaming App running on the TV, or if you have a source device like a gaming console connected directly to the TV, rather than to the AVR or processor. This may be done to minimize latency for gaming or because the source and TV support a resolution or frame rate not supported by the AVR or processor. In these situations HDMI-ARC may be used to route audio from the TV to the AVR or processor.

This connection may also be used to enable you to play high quality digital audio from your TV through your main audio system via the HDMI-ARC input on the XDA-3.

When you use HDMI-ARC, the audio signal travels “backwards” through the HDMI cable that normally carries the video signal from the AVR or processor to the input on the TV.
The HDMI-ARC audio signal travels FROM the input on the TV TO the output of the AVR or processor. Therefore, when you use the HDMI-ARC Input on the XDA-3, you will be connecting an HDMI cable from the HDMI-ARC Input on the XDA-3, TO THE HDMI-ARC INPUT ON THE TV.

Note: EVEN THOUGH YOU WILL BE USING THE HDMI-ARC CONNECTION ON YOUR TV TO OUTPUT A DIGITAL AUDIO SIGNAL, THAT CONNECTION IS NORMALLY USED AS A VIDEO INPUT ON THE TV, SO IT WILL BE LABELLED ON THE TV AS AN HDMI-CEC/ARC INPUT.

Note: The HDMI-ARC connection between your TV and the XDA-3 uses an ordinary HDMI cable.
This connection does not require a high speed HDMI cable. HOWEVER, BE SURE TO USE AN HDMI CABLE THAT INCLUDES AN ARC CONNECTION, WHICH VIRTUALLY ALL MODERN HDMI CABLES INCLUDE. IF YOU PLAN TO USE A SPECIAL POWERED HDMI CABLE OR OTHER TYPE OF HDMI EXTENDER, BE SURE THAT IT ALSO SUPPORTS ARC. ALSO NOTE THAT, WHILE WE EXPECT HDMI-ARC ON THE XDA-3 TO WORK WITH MOST POWERED CABLES AND EXTENDERS THAT SUPPORT ARC, WE CANNOT PROMISE THAT IT WILL, AND CANNOT PROVIDE SUPPORT IF YOU ARE UNABLE TO GET IT TO WORK.

Note: Once you connect the HDMI-ARC Input on the XDA-3 to your TV it should appear on the list of output devices on your TV. Your TV should automatically detect and use ARC rather than eARC. Your TV should also automatically detect that the XDA-3 is a stereo device and automatically send audio to it in the correct audio format.

Care and Maintenance

Periodic Maintenance

Your XDA-3 requires no periodic maintenance or calibration.

Cleaning Your XDA-3

• If necessary, the XDA-3 should be cleaned gently with a soft rag.
• If something sticky gets on the front panel or case of the XDA-3, it should be cleaned with a mild cleaning solution applied to a soft rag, followed by wiping with a clean rag dampened with plain water and drying with a soft dry rag or cloth.

Note: DO NOT spray water or cleaning solution directly onto the XDA-3 or into the display or connectors.

Replacing The Batteries in Your XDA-3 Remote Control Emotiva recommends using high quality Alkaline AAA batteries in the XDA-3 remote control.

• Remove the back plate of the remote control.

The back plate of the XDA-3 remote control is attached magnetically. To remove the back plate, insert a small screwdriver into the small slot on the back plate at the bottom edge and pry it gently upwards. As soon as the back plate is free of the magnets holding it, you will be able to lift it entirely free of the body of the remote control.

• Locate the battery holder.
• Note the direction in which the batteries are installed in the holder.
• Remove the depleted batteries and dispose of them in accordance with the manufacturer’s recommendations.
• Insert new batteries, taking care to insert them in the same orientation (facing the same way) as the original batteries.
• Replace the back plate (the slot should be toward the bottom end of the remote control and the small metal loop next to the slot should be on the inside when the back is in place.)

Your remote control is now ready to use.

Note: Your XDA-3 may arrive with the batteries packaged separately, or the remote control may arrive with batteries already installed, but with a small insulator installed between one battery and the battery contact to prevent the batteries from discharging in shipping. If so, then simply follow the instructions for opening the remote control, and pull out the small insulator strip that is inserted between the end of the battery and the battery contact, before using your remote control.

User-Selectable Oversampling Filters (DAC):

• Filter #1: Linear Phase Fast Roll-Off.
  

• Filter #2: Linear Phase Slow Roll-Off.
  

• Filter #3: Minimum Phase Fast Roll-Off.
  

• Filter #4: Minimum Phase Slow Roll-Off.
  

• Filter #5: Apodizing Fast Roll-Off.
  

• Filter #6: Hybrid Fast Roll-Off.
  

• Filter #7: Brick Wall.
  

The graphs on the next page show the typical impulse response and frequency response of the various filter options. (The frequency response plots correspond to an input sample rate of 44.1k or 48k. The roll-off frequencies will be higher at higher sample rates.)

Note that most of the filters deliver a flat frequency response in the audible spectrum. The major differences between the frequency responses of the various filters occur outside the audible frequency range, and at extremely low signal levels, and contribute little to the audible differences between the filters. The audible differences between the filters are mainly due to the amount and type of pre-ringing and post-ringing that result as musical transients are processed by the different filters – and can be quite subtle. In many cases you will find that specific high quality recordings will sound “more natural” or “more real” when you select one particular filter option.

Since the ideal filter option is both a matter of personal preference, and of the specific content you are listening to, we have provided a button that allows you to cycle through the various options right on the remote control. Press the Filters Button once to display the current filter; and press it multiple times to cycle through the available filter options.
