Is there an enabled high pass on the L/R channel on the Arylic 2.1 amp?

I’m currently not connecting a sub so I would like the main speaker to get the full range signal.
However I can hear that they are not producing the “normal” bass they used to with another amp.

So, anyone know how to disable the high pass? :confused:


There seems to be a hardware filter at around 400Hz. Take a look at this post:

I managed to find out that there is a high pass on the main channels (L+R)
And that the only way to get rid of it is to buy the ACPWorkbench tool (20USD)

So problem solved.

When I bought the arylic 2.1 amplifier, I also bought the ACPWorkbench and all I can say about that is that you have LOTS of settings you can play with when it comes to sound quality; In order words that piece of software is worth it 20$ extra.
