ONKYO HTX-22HDX PAW 2.1-channel AV Receiver with Built-in Subwoofer

First, the white, dirty-looking or scratched areas on the front of the main unit are where the "protective film applied when new" has been peeled off. See the second image; the main unit itself is not in bad condition.

This is an ONKYO front 2.1ch amplifier-integrated subwoofer AV amplifier.

I used it occasionally for watching movies until a few years ago when I stopped watching TV, etc. I have confirmed that sound comes out when connected to a TV (HDMI, RCA).

It seems to have various functions, but I haven't been able to use all of them since I bought it due to my environment, so I may not be able to answer questions like "Can you do XX?".

Included items:
Main unit
Speakers
Speaker wiring & mounting hardware
Remote control
Power cable
Optical cable

I should have the instruction manual somewhere, but I can't find it no matter where I look, so it's not included. However, there is an online manual (PDF), so please refer to that.

Shipping is planned in the original box shown in the first image behind the main unit, but if you negotiate a discount, I will change the shipping to the "smallest dimensions possible". I will consider reasonable discount negotiations, taking into account the various costs involved.
