2.1 amp board with high pass?

[bcodemz]

Can someone recommend a 2.1 board that has a high pass for the stereo channels? I really like the TPA3116 2.1 board, but apparently (and correct me if I'm wrong), it doesn't have a high pass filter for the stereo channels.

Thanks.

There always is a high pass filter on 3116 input, dc blocking caps and inputimpedance, like datasheet also mentions. If you reduce value of these 4 inputcaps you'll limit bass main channels are able to produce.

Could you explain further? If I high pass the input, then wouldn't there be no bass going into the amp at all?

Is there anything that I can read that'll teach me the various parts of an amplifier and what it does?

Thanks

page 14 for high pass, eg I use an amp with 100nF inputcaps, you can calculate what -3dB point should be

I'm actually a newbie when it comes to amps. Where can I read about all this stuff and educate myself of all this?
