LUMIN FAQ

Which UPnP AV music software is best for LUMIN?

LUMIN strongly recommend MinimServer. It supports all the features of LUMIN and much of the development and testing of LUMIN has been performed with MinimServer.

The current release of MinimServer supports Windows x86, Windows x64, Mac OS X, Linux x86 and Linux ARM.

Installation instructions are also available for recommended NAS products from Qnap and Synology: http://minimserver.com/installing.html.

Which NAS products are best for LUMIN?

LUMIN recommend Qnap and Synology, partly because they are good products and partly because there are installation instructions available for installing our preferred music server, MinimServer.

Do I need to tag my music?

Yes, the LUMIN App uses these tags to organise your music.

Historically, server and control software has performed poorly with this method, leading to many people organising their music using folder structure on their servers. LUMIN seeks to improve on that system using tags to improve flexibility and browsing speed.

We recommend that you use appropriate tagging software to correctly tag your music library. A good example is Mp3tag.

How long does the LUMIN App take to cache my music?

The very first time you use it, the LUMIN App will cache all the artwork. This can take a few minutes (approximately 250 albums per minute depending on the resolution for the artwork). After this first time, LUMIN only needs to load any new music that you might add to your library. Usually only a few seconds.

It is possible that a software update may require your library to be re-cached.

Can LUMIN control my amplifier volume?

Currently, this feature is not available. The app volume control digitally adjusts the output from LUMIN. This is not necessarily the highest quality method and therefore we recommend that you use your amplifier's remote control for this purpose.

It is possible that certain network-connected amplifiers can be supported in the future.

Can the LUMIN App be used with other UPnP AV systems?

LUMIN uses the Linn UPnP AV Extension and it is our intention to provide the LUMIN App for use with other systems that also use this extension. Currently, however, no warranty or guarantee of operation can be provided with systems other than LUMIN.

The LUMIN App will not currently control generic UPnP devices.

LUMIN Settings (accessed through the App)

Lumin Settings Name Enter your chosen name for this particular LUMIN.
Lumin Settings Firmware Check If set to 'Yes', LUMIN will automatically look for updates whenever the App is started.
Lumin Settings Front Panel Display The LUMIN Front Panel Display has adjustable brightness.
Lumin Settings Idle Sleep LUMIN will go to sleep (saving a small amount of power and turning off the Front Panel Display) after the set period of inactivity.
Lumin Settings Analog Audio Output Level Some systems (perhaps with a high-gain pre-amplifier) may be better matched using the 'Low' setting. It uses a combination of DAC settings to lower the output level by around -4db.
Some CDs (generally old) have a 'flag' for 'pre-emphasis'. High frequencies were occasionally increased in magnitude in order to improve Signal-to-Noise ratio. Digital files don't carry this 'flag' so only set this to 'on' for files that you know to need it. More info here. In-progress list of CDs here. This setting has no effect on on High resolution files, or when re-sampling is used.
Lumin Settings Digital Audio Output If you have no need for the Digital Audio Output (to an external DAC), then you can turn it off here.
Lumin Settings Digital Audio Streaming LUMIN Streaming is the function that allows compatibility with Apple AirPlay. If you have no use for this feature, you can turn it off here.
Some songs were recorded, or mastered with the phase inverted, some users may like to restore to correct phase during playback. For general use, this should be left 'Off'.
Lumin Settings Re-Sampling When set to 'Off', LUMIN will play all files in their native sample rate and resolution. If you set it to 'Custom' the options below appear.
Lumin Settings 384kHz PCM Here you can choose to downsample 384kHz PCM audio files. This may be used for compatibility with an external DAC.
Lumin Settings 352.8kHz PCM Here you can choose to downsample 352.8kHz PCM audio files. This may be used for compatibility with an external DAC.
Lumin Settings 192kHz PCM Here you can choose to downsample 192kHz PCM audio files. This may be used for compatibility with an external DAC.
Lumin Settings 176.4kHz PCM Here you can choose to downsample 176.4kHz PCM audio files. This may be used for compatibility with an external DAC.
Lumin Settings 96kHz PCM Here you can choose to either upsample or downsample 96kHz PCM audio files. You may prefer the upsampled audio - try it and see. Downsampling may be used for compatibility with an external DAC.
Lumin Settings 88.2kHz PCM Here you can choose to either upsample or downsample 88.2kHz PCM audio files. You may prefer the upsampled audio - try it and see. Downsampling may be used for compatibility with an external DAC.
Lumin Settings 48kHz PCM Here you can choose to upsample 48kHz PCM audio files. You may prefer the upsampled audio - try it and see. DSD upsampling is a new feature with Firmware 3.0.
Lumin Settings 44.1kHz PCM Here you can choose to upsample 44.1kHz PCM audio files. You may prefer the upsampled audio - try it and see. DSD upsampling is a new feature with Firmware 3.0.
PCM Output Bit Depth Here you can choose to upsample PCM audio files to 16 or 24 bit resolution. You may prefer the upsampled audio - try it and see.
