Let me explain how the new stereo controls work for Bongiovi DPS 2.1. They are a bit different than 2.0.
When listening in Built-In or External Speakers mode, the Stereo Controls adjust our Dynamic Stereo Enhancement algorithm. Turing the effect off or moving the circles to the center will result in normal stereo sound. Turning the effect on and moving the circles wider will increase the width of the stereo image while maintaining the strength of virtual center channel content like dialog, sound effects (like guns or explosions), singing and drums.
When listening in Headphones mode, there is now a completely different effect. You will notice the circles “snap” to three different locations inside the Stereo Controls box. That is because we are switching between modes 2 (widest) 6 (middle) and 5 (mono) in our new Headphone Enhancement algorithm. Turning the effect off returns to normal stereo.
In our office, we like to turn any stereo enhancement off when listening to music. However, all profiles in Music mode are calibrated to sound great with the stereo effect turned on with the circles in their default positions.
I personally use the middle or center headphone effect when listening to older music where the drums are on the right channel and voice is on the left. Did you know those wacky old stereo mixes were done by the junior engineers back in the day? Only the big shots mixed the mono versions that went out on the air.
We really enjoy gaming with headphones using the widest headphone setting. Try the VR profile with this!
I hope this clears things up. Let me know if you want further details. Cheers!
