I obligation home A/V installation tips to verbs sour a ability DIY home entertainment system setup? THANKS?
Answers: I assume you don't enjoy things prewired in the walls, so I would suggest plan to hair wiring contained by plastic wiring channel (available in a range of types at Home Depot). They will allow you to run the wiring along the baseboards (assuming they are white).
Wire speakers near 12 or 14 awg wire. Ensure you see proper phasing (red to red, black to black).
For best video make sure you hold light control (e.g. dutiful blinds or curtains on windows), and paint the walls a medium colour to cut pallid reflection.
Ensure a balanced bit of soft material contained by the room to cut audio reflections. Don't plan everything symmetrical if you can avoid it. Put a mat or area rug on the floor, chiefly in front of the foremost speakers. If the room is too reverberant you will need to consider aural panels / bass traps. Google it.
Do a google force out ("speaker+placement") and follow suggestions for speaker placement, including height). Look for specific suggestions for sub-woofer placement and follow them.
Mount the HDTV screen so that a point 1/3 of the blind height is at roughly speaking eye level contained by your normal sitting room position. From a distance perspective, a 52" 1080p HDTV should be viewed from around 7 ft (9 ft if 720p). See link.
Make sure you calibrate the TV and the audio. Use Avia or similar for the picture (for brightness, contrast, colour, etc.) and run the auto equalization on the addressee (to set sound level, delay, etc).
Mount the components on a rack or surrounded by some way you can access the reverse for wiring adjustment, etc.
Use a UPS/surge protector for all equipment.
If you want to store the components use IR Blaster type IR repeaters to allow putting componenets behind doors. Use an IR extender to allow the AVR to be controlled within the second room (unless the 890 is an RF remote and the Denon can be RF controlled).
Use HDMI to wire for HD. Use Monoprice or BlueJean cable rather than Monster if you want upright but not expensive.
I'm probably missing somethings, but there's a good start.
Have fun.
