How do I get the most out of my new GSX 300 external soundcard?
We suggest you download the EPOS Software Suite from Eposaudio.com. The EPOS Software Suite turns on 7.1 Surround Sound, allows you to create different audio profiles depending on your needs, and also allows you to control background noise.
What does the Smart button do?
You can select what it does from within the EPOS Software Suite. As of today, you can select the functionality of switching between your audio profiles or switching between Stereo and Surround sound.
Does the GSX 300 work with consoles?
Will the GSX 300 improve my audio quality?
It all depends on your existing soundcard. If you don’t have a soundcard today, you might get quite a nice up-grade for audio quality.
I had 24-bit audio before installing the software suite, what happened?
The EPOS Software Suite and its 7.1 processing only support 16-bit audio today. We are working on an upgrade and hope to support Hi-Res 7.1 processing soon.
My GSX 300 isn’t playing loud enough with my headset.
The GSX 300 external soundcard was made to provide a good loudness for headsets such as the GSP 300, GSP 500 and GSP 600. If you use other headsets, please make sure that the impedance (resistance) of the headset is around 50 ohms or less. Having higher impedance will impact loudness of the audio.
We also suggest that you check that volume is turned all the way up on the volume control on your headset.
