Once you've hauled in your boxes of electronics, clear the entertainment room and lay everything out. Take inventory of what you have, and if you've forgotten something, go back out and get it before you start setting up. Before you plug anything in, place your receiver in front of (or underneath) your TV, then do a walk-through of where you want to place your speakers accordingly. For example, if you have a 5.1 system, consider placing 1 speaker directly in front of your TV, 2 on either side of the TV, and 1 on either side of the seating area. Leave your subwoofer alone for now. Your setup will differ based on how many speakers you have, the layout of your room, and the height of your seating; this is simply a general reference. The 2 speakers on either side of the TV should be placed firmly on the ground or a stand. If you have a larger speaker system, place surplus speakers around or behind the seating area in an arc; this will enhance your surround-sound experience. From a top-down perspective, your front speakers should form an equilateral triangle with the center of your seating placed at the apex. Take the width of your room and the general number of people you hope to seat into account here--your speakers will need to be placed farther apart from one another if you hope to engage each member of a crowded room equally, whereas they can be fairly close together if you're the sole occupant. Surround-sound speakers are best place to the immediate left and right of your seating arrangement, with the speakers elevated to roughly standing ear level. If you don't have enough room to the left and right, you can always mount the speakers behind your viewing area. Once you've determined roughly where everything should go, attach your receiver to your TV and any existing pieces of hardware (consoles, Blu-ray, etc.). You should have a general A/V input (i.e., HDMI cable, optical cable, coaxial cable) to connect your TV to your receiver--this will differ based on your hardware, especially if you have older TV and receiver models. You may want to pull your TV away from the wall while you do this for ease of access. This is where you'll need your speaker cable; though some brands include these cables by default, you're better off buying your own. If you have a system higher than 2.1, plug in your remaining speakers to your receiver using speaker cable. Listen to a DVD or some music that you're familiar with; to figure out how to tweak your speakers' placement, walk around the room and take note of where the audio quality dips or otherwise sounds different than normal, then adjust the speakers accordingly. Pay special attention to sound distortion; this can be especially indicative of poor speaker placement. To avoid distortion, make sure your speakers have plenty of room all around them to broadcast sound--don't place them in a corner or between objects. You may also need to play with your TV's audio settings to even out bass and treble. Since your subwoofer's sound quality will likely change based on the size and shape of your room, there isn't one universal way to place it, so experiment until the sound is balanced and refined. A good rule of thumb with subwoofers is never place them directly against walls or in corners. Even with the right audio adjustments, this can distort your bass. Entertainment systems with limited space usually resort to placing the subwoofer on one side of the TV, facing the seating area but not angled toward the viewer's head height like the other speakers. Walk around the room one final time to ensure your TV's audio is even and balanced throughout, experimenting with different bass settings to eliminate distortion as you go. Remember that your end goal is to distribute the audio equally to everyone in the room; therefore, ensuring that the audio is consistent throughout the seating area should be your top priority.

summary: Unbox everything and lay it out. Do a dry run. Place your speakers. Plug in your receiver. Plug your front speakers into your receiver. Plug in your other speakers. Turn everything on. Connect your subwoofer. Double check your calibrations.

Summarize the following:
To ensure that you're purchasing pure tung oil, look for the words "100% tung oil" printed somewhere on the container's packaging. You can find tung oil at a local paint store or hardware store. 1 quart (0.95L) of tung oil or Waterlox will cover about 15 feet (4.6m) of butcher block. If you'd rather apply a longer-lasting product than tung oil, you can seal the butcher block using a more substantial chemical sealant, like Waterlox. Both products are food-safe. Dip a clean, dry cotton cloth or rag into the container of tung oil or Waterlox. Then use the cloth to rub the sealant across the surface of the stained butcher block. Work in long, straight strokes that parallel the direction of the boards in the butcher block. Give the sealant a full 12 hours to dry. Sealing the butcher block is a time-consuming process. It will need several layers of tung oil or Waterlox. Use the same method for each layer: saturate a clean rag with sealant and then rub it along the surface of the butcher block. Use a clean cloth to remove any excess sealant. Ensure that each layer has at least 12 hours to dry before applying the subsequent layer. Avoid using the counter for 7 full days so the oil has enough time to fully soak into the wood. Once the week has passed, you can use your stained butcher block counters. You can still use your butcher block countertops before a full week passes. However, they'll be oily and may stain your dishes or clothes. Tung oil wears off eventually, at which time it needs to be replaced. Every 4 monthsor as soon as the surface of the butcher block begins to look fadedapply a layer of tung oil to the wood. The additional coats of oil won't take a full week to dry. To be on the safe side, though, give each layer 3-4 days before using the countertops.
summary: Purchase 100% tung oil from a local paint store. Apply a layer of tung oil to seal the stained butcher block. Apply 4 additional layers of tung oil to the butcher block. Give the tung oil a full week to dry. Put on a new layer of tung oil every 4 months.
