Is color printing a hidden option on this printer?

So, here is a scenario. I'd like to extend background music from one part of the house to another, Using an amplified speaker I already own. In this situation, mono audio is preferred. I am not seeking advice on why using a pair of speakers is "better", I'm asking if this will work for my application.

The ideal answer is: "The audio frequency response passed through the system is X (like 20) Hz to Y (like 20,000) Hz or whatever it is."

So, will the audio output of the receiver contain the normal full range spectrum, or does it filter out all the midrange and highs and only pass through the frequencies used by a subwoofer.

Before you answer, I've already read the specifications.

I purchased Bose computer speakers with the turntable at Best Buy. I was told I could plug the turnable directly into the speakers. I am unable to get it to work.....can't figure out how to plug in. P.S. I am totally a novice at this stuff.

Does this printer color scan multiple pages at once using the paper feeder or does it only scan one page at a time using the flatbed?

Thanks.
