Play High Resolution Audio from a Windows System 
 

To play high resolution audio files such as DSD, DSF, DFF, FLAC (24 bit) and many other high 

resolution formats, you will need to install a media player that is capable of playing 24 bit 

192kHz music. There are a number of media players such as Foobar2000 (free), jRiver ($) and 

others that are available for download from the internet. 

 

We will publish additional guides to the installation and configuration of various media players 

and their use with the GIA-275 on our website.  All of the media players we have tested install 

easily and ‘see’ the GIA-275 immediately. Most have built-in and/or addon equalizers that 

enable you to customize the sound to your speakers, listening environment and personal 

preferences. 

 

Foobar2000 is available here: 

http://www.foobar2000.org/

 (Free & many addons are available) 

jRiver is available here: 

http://jriver.com/

 (free 30 day trial. Full featured and nice UI.) 

 

There are many Internet sources for both free and paid high resolution audio files.  Here are 

A few that might be of interest to you:

Connect a CD or DVD player to the GIA-275 
 

You can connect the R&L analog outputs from a CD or DVD player to the AUX1 or AUX2 analog 

inputs. Alternatively, if your CD or DVD player has optical or coax audio output connections, 

you can connect the optical or coax connector from the CD or DVD player to the D1 or D2 

optical or coax inputs.  

 

CAUTION: 

Do NOT make simultaneous optical and coax connections to the D1 input or to the D2 

input. 

 

Connect a Blu-Ray player, Cable box, Satellite Receiver or TV to the GIA-275 
 

Most Blu-Ray players, cable boxes, satellite receivers and TVs have analog outputs and/or 

digital audio output via optical or coax connections.   If the device has analog R&L output 

connectors you can connect it to the AUX1 or AUX2 inputs on the GIA-275.  If the device has 

digital optical or coax audio output you can connect it to the corresponding D1 or D2 connector.   

 

IMPORTANT: 

Many Blu-Ray players, cable boxes satellite receivers and TVs have default digital 

audio output configured for 5.1 surround sound.  The GIA-275 is a stereo device and will not 

work properly if the digital audio input stream is encoded for 5.1 surround sound.  To overcome 

this problem you may need to reset the default audio output on the Blu-Ray player, cable box, 

satellite receiver or TV to stereo before it will work with the GIA-275.  The audio setup menu 

on your Blu-Ray player, cable box, satellite receiver or TV may use a different term for stereo.  

Terms such as PCM, LPCM, Standard Audio etc. are common. 

 

CAUTION: 

Do NOT make simultaneous optical and coax connections to the D1 input or to the D2 

input.
