It is possible to clean up the sound with a processor such as the MDX1600 because it has a side chain, the side chain is an in/out circuit that is placed between the compressor/limiters input/output circuits to which an external device can be hooked up, that manipulates the compressor/limiters frequency response.
Here in the side chain, you can add an equalizer. Adding something like a 21 to 36 band EQ in this area gives better control over the entire audio frequency spread, you can increase a few frequencies above 0dB, while reducing some below 0dB or even to the point that frequency is missing entirely at the output of this device.
When using an EQ it is best to study the audio frequency spectrum and understand what parts of music or noise fall under that particular frequency, then determine if reducing that slider improves the signal to noise ratio. Just be careful with increasing, because it does not take much to over-shoot and create unwanted noise.
AM broadcasting may require some reduction to complete removal of all frequencies above 12KHz for example.
FM may require reduction of frequencies below 250Hz, an EQ is good for doing that.
Here is a link to the Behringer Autocom Pro XL MDX1600 page, it has photos, plus links to download the manuals so you can explore and decide if it fits your criteria. Make sure you expand the page to view all of the various owner's manuals, pick the ones labeled English language and download the manuals.
I do have to add, sometimes reading multi-langauge owner manuals are a bit confusing, the manual for the MDX1600 also covers 2 other model numbers, plus it has multi-langauge instructions throughout the manual, so just take your time.
Now, to be sure, there are better processors out there, but if your budget is limited, Beheringer equipment is usually priced to sell and is good equipment to start out with and learn on.
There is the Behringer DSP9024 6 band compressor/limiter, but let me asure you, this processor is very difficult to set up and contains many on-screen displays you have to jump through, the MDX1600 and its sister units the MDX2600 and MDX4600 are easier to learn on for the beginner.
If you decide to read through the MDX1600 manuals -- there should be 3 in English, including a quick-start guide and specifications guide -- and if you have any questions about a specific feature, please feel free to ask.

You said: "AM broadcasting may require some reduction to complete removal of all frequencies above 1KHz for example."
I quoted: "
A voice frequency (VF) or voice band is one of the frequencies, within part of the audio range, that is used for thetransmission of speech.
In telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. It is for this reason that theultra low frequency band of the electromagnetic spectrum between 300 and 3000 Hz is also referred to as voice frequency, being the electromagnetic energy that represents acoustic energy at baseband. The bandwidth allocated for a single voice-frequency transmission channel is usually 4 kHz, including guard bands, allowing a sampling rate of 8 kHz to be used as the basis of the pulse code modulation system used for the digital PSTN. Per the Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the highest component of the voice frequency via appropriate filtering prior to sampling at discrete times (4 kHz) for effective reconstruction of the voice signal."
Hi wdcx you caught me before I sent the re-edited version up to the forum board, I re-read my post after it was originally posted and seen several typos, to which I have corrected.
Your post appears to be a copy and paste from the web. Wikipedia?

Yes.
Cool, thanks for sharing!
