Pre-requisites

Wired broadband connection

You will need to connect the AudioGlu to a broadband connection with an Ethernet cable. This is to enable your remote controller to access the unit and for CD album name, track names and cover art to be downloaded. If your broadband router is a long way away from your HiFi you could try using a HomePlug device which enables your network connection to be made over your mains power wiring. Amazon or ebay have a good range of devices which can be found by searching for “HomePlug” - you will need two devices, one for each end of the connection.

Home WiFi network

You will need to have the mobile device you intend to use as a remote controller connected to your home WiFi network so that it can communicate with the AudioGlu player.

Digital to Analogue Converter (DAC)

You will need a DAC to convert the digital signal from AudioGlu to an analogue signal that your HiFi system can amplify. There is a huge range of DAC's on the market and it's a good idea to listen to a few at your local HiFi dealership. We would recommend finding one that has an asynchronous USB interface capable of handling USB class 2 audio for the best results. AudioGlu will also output optical and coaxial S/PDIF and earlier versions of USB audio if required. There are two types of USB connector on the rear panel, the ones with a blue plastic middle section are USB3 and the others are USB2. It is worth experimenting with the different types of USB socket to determine which works best with your particular DAC. Only AudioGlu Stealth has USB3 sockets.

iPad, iPod, iPhone, Android phone or tablet

In order to remote control the AudioGlu you will need one of the devices named above connected to your home WiFi network.

Connect it all together and power up

  • Plug one end of an Ethernet cable into the network socket on the back of the AudioGlu case and the other end into your home network.
  • Connect your DAC either via USB or S/PDIF to the appropriate connector on the back of the AudioGlu case.
  • Connect the external power supply to the connector on the back of the AudioGlu case and connect the mains power lead to a wall socket and switch on.
  • Momentarily press the on/off button on the front of the AudioGlu case. A blue indicator light adjacent to the button will illuminate and the unit will be fully operational within about 15 seconds.

Turning the AudioGlu unit off

Momentarily press the on/off button on the front of the AudioGlu case and the blue light will extinguish within about 15 seconds when the unit has finally shutdown. Do not turn the unit off at the power socket instead of using the on/off button, as this may result in corruption or loss of your music files. If for some reason the unit does not shutdown after following this procedure, you can press and hold the button to force a power down but only do this if there is no alternative.

Copying (ripping) a CD

Insert the CD you want to copy into the CD slot on the front of the unit and the unit will immediately start to make a perfect copy. Because of the amount of checking that is performed, it takes about 5 minutes to fully copy a CD. When the CD is fully copied it will automatically be ejected from the slot. If the CD is damaged in any way the copy operation will take considerably longer as AudioGlu tries to recover all of the information. If it is taking too long, you can press the eject button to retrieve the CD and abandon the operation.

Album artwork and tags are also downloaded when a CD is copied. Downloaded artwork is used by the UPnP server and is different to the artwork presented by MPaD, MPoD, MPDroid etc. AudioGlu finds the best matching artwork that it can for the CD but in some circumstances artwork is not available or is badly indexed leading to the wrong image being downloaded. The thumbnail quality image files are stored in each CD album directory and are called folder.jpg these images are obtained via One Music API. If you wish to obtain better quality images or reorganise the tags, we recommend using a software package called Bliss which can be installed on your home PC and configured to update the files on AudioGlu via the shared network directories.

Setting up the remote control application

If using MPaD or MPoD you simply need to select the AudioGlu Player from the discovered devices section of the settings menu and then confirm the output device you want to use.
If using any of the other applications you will need to enter some information in the appropriate hostname or IP address field on the application's settings page. If you have a recent home broadband router such as the latest BT equipment, you only need to enter the name “audioglu” when you are asked for a hostname or IP address. Older equipment often doesn't support this and you need to find out what IP address (like a telephone number) your router has allocated. The best way to do this is to log onto your routers admin page where you will be able to find the information out. Unfortunately due to the large variety of installed equipment we cannot provide details for every broadband provider.
In all cases it's also worth logging onto the router's admin page to find a setting that fixes the IP address of the AudioGlu unit, otherwise there is a possibility that the IP address will change from time to time and the remote controllers will be disconnected.

Making a backup of your music

You will need to use an external USB hard disk drive that is at least the same size as the disk in the AudioGlu, which is 1TB or 2TB. The drive will need to be formatted to either NTFS or FAT before connecting.
All you need to do is to plug the USB cable from the external disk drive into one of the USB sockets on the AudioGlu and a backup will start immediately. Most drives have an indicator light that flashes when the drive is in use and you can use this to determine when the backup has finished. You can only remove the USB cable from the AudioGlu when it has been turned off, DO NOT remove the USB cable from the AudioGlu while it is powered up or you may lose some of your music files. Only new files are copied onto the hard disk, so if you make frequent backups the operation should be reasonably quick. The two, blue coloured, USB sockets on the rear panel (only on AudioGlu Stealth) are USB3 and offer excellent performance if you have a USB3 external drive.

Restoring your music files

You are able to simply restore your music files to a new AudioGlu unit by renaming the backup subdirectory on the external USB hard disk drive that you used to make the backup. You need to first of all connect the USB hard disk drive to a computer, locate the subdirectory named "audioglu_backup" and rename it to "audioglu_restore". Safely eject the USB drive and then connect it to the AudioGlu. The previously backed up music files will now be automatically copied to the new AudioGlu system. You can also use this method to copy files from one AudioGlu to another as existing files will not be overwritten.

Copying your existing files onto AudioGlu

The AudioGlu server has a Windows compatible network drive which you are able to navigate to using the file explorer. You can then drag and drop your music files into the folder called "music". We strongly recommended that you store the music files in a "Artist\Album" directory layout. Most audio files types are supported such as FLAC, MP3, WMA, Apple lossless etc. provided they do not have copy protection or DRM.

Copying MP3 files from AudioGlu

AudioGlu (Version 1.2 and higher) provides a Windows compatible network drive called "mp3music" which contains a mirror image of the "music" folder with MP3 files of your music collection. These are smaller than the lossless FLAC files AudioGlu creates and can be used on most portable music players. Please note that only FLAC files are converted to MP3.

Updating the AudioGlu system

From time to time, we may make updates to the AudioGlu firmware. Registered users will be notified by email of how to download an ISO CD image to burn onto a CDROM or can request a CD to be sent by post for a small administration fee. All you need to do is to insert the CD when the AudioGlu unit is powered up and the update will happen immediately. The CD will be ejected when the update is complete. In most cases you will also need an active internet connection while the update is being performed.

Locating the AudioGlu system

The AudioGlu Stealth has no fan inside and is passively cooled, so there must be enough space for cool air to flow around it. Positioning the unit in an enclosed environment or one with poor air circulation will lead to the system overheating as there will be insufficient cool air passing over the heatsink to transfer the heat away from the unit. For example, even a shelf a few inches above the unit will impede airflow and may cause overheating.

The AudioGlu Fox and Wolf have active cooling which makes them a better choice for installations where airflow is limited. The internal fan is silent as it runs at a very low speed during normal operating conditions.

DAC test results

AudioGlu should work with all DAC's without any issues. However, as with all things, there is a possibility of incompatibility especially for hi-res files. So in order to help you configure your system we will continually update the table below whenever we have feedback about any particular product. If a DAC is not included in the list it doesn't mean that it won't work, just that we haven't tested it yet. The following DAC's have been tested and are known to work ok at the specified bit rates. We will continue to update this list as time progresses. Due to the large number of DAC's available, please let us know of your experiences and we will include them in the table.
