Question: active or passive subwoofer?
Document: I don't have the proper speaker system to make this system preform to it's fullest. I did not know you had to have a subwoofer that has it's own independent power.
The sound is incredible. I used my existing 20 year old speakers and added a subwoofer. I would recommend this.
It has rich, clear sound output that will satisfy those who want to add a subwoofer and amplification speakers to their HDTV and gaming system, on a budget.Perfect for a bedroom, dorm room, small living room or home office, the Denon AVR-E200 is low on price and big on quality sound.
It's just better designed.Setup is really easy. In the rear, everything is color-coded (as are the cables). There are easily distinguishable inputs for speaker wires (Front L/R, Rear L/F, Center and Subwoofer). It would have been nice if there was an option for `banana plugs', but that's minor. You can hook up your satellite, cable and monitor by `optical', HDMI or standard audio cable.
I bought this receiver for my PC after my Klipsch Promedia subwoofer/amp combo died. The lack of network features does not matter when hooked up to a PC. I'm using the Klipsch satellite speakers from the Promedia setup, and also bought a PSW10 for the subwoofer. I have no complaints, the avr-e200 has been perfect for my needs.I still only give it 4 stars and not 5 because it is entry level.
I haven't seen anything that suggests each port works better for the type of input device. I think it would have been more convenient to just label them 1,2,3,4.Sound is really awesome. In fact, we noticed it was better then the Yamaha (which was never bad) even though we are using the same speakers we've had for all these years, including subwoofer.FM and AM radio are included. It will keep up to 56 presets which you can have it automatically setup.
At the time I write this it is an unbelievable value for a bit over $160. Full surround, lots of imputs and everything looks very professional. Within 10 minutes I had this hooked up to satellite, a very old DVD changer, 2 Polk speakers, a subwoofer, the fm and am antennas, and was surprised how easy it was. I was unsure that the dvd changer with rca jacks would play on a hdtv using an extra hdmi cable but easy peasy it did.
