Not included: An iOS (iPad or iPhone) or Android device is required to interface with and control your Aurender. The Aurender must be connected to a Local Area Network (LAN) via Ethernet (CAT5 or higher) in order to facilitate communication between your remote device and the Aurender. Please review the "Connect to Local Area Network (LAN)" section of the included Quick Start Guide for more information on network connectivity.
Digital Transport
This model is a high performance digital audio transport. It features digital outputs only - there are no analog outputs on board this model. Pair this model up with a high performance Digital-to-Analog Converter (DAC) for a complete digital front end solution.
DAC Compatibility
AES/EBU and SPDIF outputs & inputs are universally compatible. However, with USB, compatibility between any two devices is not always guaranteed! Sometimes, special drivers or software provisions must be made to establish compatibility over USB. DACs that fully adhere to the USB Audio Class 2 (UAC2) protocol will be supported without issue.
For DSD playback, if the DAC supports the industry standard DoP protocol, then it will be compatible with Aurender's DSD output. DoP is a lossless, unadulterated transmission of DSD from source to DAC. It is NOT to be confused with DSD-to-PCM transcoding, which is usually less desirable from an audio performance perspective.
On some Aurender models (see "File Type & Resolution Support" comparison table below), "Native" DSD output is available via USB. However, only a very small handful of select DACs support "Native" DSD input FROM A LINUX BASED SOURCE. Most DACs that report Native DSD input only work with ASIO drivers for Windows computers. Native DSD compatibility must be detected and enabled on a case-by-case basis.
In general, if a DAC works with a Mac computer without the need for any custom drivers, it will work beautifully with Aurender servers as well. Consult your DAC manufacturer for confirmation of USB compatibility with a Linux based sourced component like Aurender.
Front Panel
1. On/Off
With the AC switch on the rear in the ON position, simply press and release the front panel On/Off button to turn the Aurender on or off. The surrounding LED light will pulse while the unit is starting up or shutting down, and it will stop pulsing when fully turned on or off. Pressing and holding the On/Off button will trigger a forced shut down and this should be avoided. More information on proper shut down procedure is found here: What is the proper way to shut down my Aurender?
2. AMOLED Display
Front panel display preferences can be adjusted in the Conductor app in the "Front Display" section of the Settings menu. The display will automatically go dim after no playback or other activity has occurred for a period of 3 minutes.
3. Display Menu
Press the Display Menu button to cycle through various display options including Song Information and Playlist Menu. Playlists may be selected and played using the four buttons on the right side of the front panel display. Use the Previous (5) and Next (6) buttons to scroll between playlists. Use the Play/Pause (4) button to select a playlist. After the playlist is selected, press the Play/Pause button again to start playback.
4. Play/Pause
Press to start or stop playback. Press and hold for 8 seconds to manually engage Remote Support mode for technical support. More info on Remote Support mode here: How can I contact Aurender Technical Support?
5. Previous track
Press to skip to the previous track.
6. Next track
Press to skip to the next track.
Rear Panel
1. AC Power Switch
Press the top of the rocker switch to turn AC power on, press the bottom to turn it off. The rear panel power switch should be used to turn the unit off only after the unit has been shut down via the front panel On/Off button or via the app. The front panel On/Off button LED light will pulse while the unit shuts down. Once it is dimly lit after shut down procedure is complete, it is safe to flip the rear panel AC power switch to the "off" position. More information on proper shut down procedure is found here: What is the proper way to shut down my Aurender?
2. AC Power Socket
Connect an IEC AC Power cord to a grounded power source/outlet.
3. Dedicated proprietary USB Audio Class 2.0 Output
Aurender's filtered and isolated USB port is designed to connect to asynchronous USB DACs. Use a USB 2.0 certified A/B cable to connect with a compatible USB DAC.
4-5. AES/EBU XLR Outputs
Use 110 ohm AES/EBU cable(s) to connect the AES/EBU input of a DAC. The Aurender W20 has two AES/EBU XLR outputs to support dual-wire AES/EBU output for use with compatible DACs. AES/EBU output settings can be configured in the "Advanced 2" section of the Settings menu.
6. TOSLINK Optical Output (SPDIF)
Connects to the optical input of a DAC. Use a TOSLINK optical cable.
7. Coaxial RCA Output (SPDIF)
Connects to a digital coaxial input of a DAC.
8. Coaxial BNC (SPDIF) Output
Connects to a digital coaxial input of a DAC.
9. Coaxial BNC Word Clock Input
Connects to the BNC output of the master/word clock. Use a 75 ohm coaxial cable. Configure word clock input preferences in the "Advanced 2" section of the Settings menu.
10-11. USB 2.0 Data Ports
These USB data ports can be used to copy files from USB memory devices or for connectivity with compatible external control devices (eg. dCS USB-to-RS232 dongle, MSB Prol25-to-Clock module, Constellation preamps, etc.). For best audio performance, these ports should not be used as USB audio outputs.
12. Double Isolated Gigabit Ethernet Port
This model uses 2 transformers in the Ethernet port circuit for superior noise filtration without detrimental signal loss.
The Aurender must be connected to your Local Area Network via Ethernet (CAT5 or higher). In case there is no Ethernet connection available in the location where your Aurender is to be installed, please see the following support article for other options: What if I do not have an Ethernet/LAN connection in my listening room?

Interfacing with Advanced DACs & Clocks
Positioning
• Place your device on a flat and stable surface.
• Keep away from heat sources, such as radiators.
• Do not stack other products on top of the Aurender.
• Allow space around the device for ventilation.
• Do not place inside an enclosed cabinet without ventilation.
Precautions & Safeguards
Please read the following instructions carefully before setting up the Aurender Music Player.
• The LiFePO4 battery power supply for the audio circuits also acts as an uninterruptible power supply. In case of any sudden power failures, the Aurender W20SE will power down safely. Even so, proper shut down procedure should be observed to turn off your W20SE whenever possible.
• All devices should be turned off before making any power cables or analog/digital interconnections.
• Only plug your Aurender into grounded plugs and grounded sockets.
• Do not drop the device to avoid internal damage.
• Do not disassemble the device. Doing so may cause inadvertent damage that would not be covered under warranty.
• Keep magnetic materials away from Aurender. Hard drives and other internal electronics are subject to damage from magnetic interference.
• Do not expose device to oil, dust, water, high humidity, or smoke.
• Keep ventilation openings free from obstruction.
• When cleaning, use a soft, dry cloth. If stains remain, lightly dampen the cloth with water and gently wipe the unit with minimal pressure. Ensure any residual moisture is promptly wiped away to prevent water spots.
• Unplug power cord during severe lightning storms (after shutting down properly).
• Please note that hard drives can break down. Do not consider your Aurender the "Master" copy of your precious music library! Rather, maintain a separate master copy and consider your Aurender as a secondary backup copy. It is important to back up your music collection periodically to a separate memory device. In the event of drive failure, Aurender is not responsible for any loss of data. The drive manufacturer will only replace faulty drives under warranty and do not compensate for any loss of data.
