In order to benefit from the H1500 advanced settings, we will have to go ahead and install the latest software version from the Downloads tab of the Corsair website; at the time of the review, the available software version was 2.0.35. The GUI is very similar to the one we have found with the wireless variant and pretty easy to use: we have the volume control levels, surround settings but also the EQ:

For 2.0 Stereo, with Dolby disabled we will get on the output exactly the same material, while with surround enabled, the signal will be converted to 7.1; with 5.1 Surround input and Dolby disabled, we will have on the output 2.0 Stereo, while with surround enabled we will receive 7.1; the 7.1 Surround input will be converted to 2.0 with Dolby disabled and if we enable the surround setting, we will also get 7.1:

The Dolby Pro Logic IIx setting can be enabled by clicking on the Power button sign on the top left corner of the interface:

The GUI can also provide us with the exact software version and audio driver revision:
