If it quacks like a bass trap, walks like a bass trap, it probably is a bass trap (without over absorption of higher frequencies).

Closing up for the 4th. y'all have a great holiday y'hear now.

We custom terminate all our cables (except HDMI). Our primary cable is Planet Waves.

What I use, where I use it all depends upon the engineering requirements of each room. "Stuff" will go over the PB. PB was used in the THX Certified project, but incorporated into panels so you never saw it.

We do not use Planet Waves for speaker cable. For that we use a 12 AWG multi-stranded cable (typically from Liberty Wire & Cable). The electrical requirements are pretty straight forward ... the quality of the sheath (like for pulling through walls, however) is a different matter.

We do clean up the job site before we leave.

Here's a panorama of the room. (just a cheap trick to bump the thread)

Back to work following the holiday.

Doesn't look like a lot of progress, but that's a lot of tedious work on the walls.

That is a linacoustic product on the baffle wall. It is a very thin layer. It's purpose is only to absorb any sound reflecting off the back of the AT screen to the baffle.

Let's say the opposite walls are similar..not necessarily identical; but, each room is different.

Should be some more photos coming later (still working on site)

Higher level mathematics.

Brad:

I don't mind taking your question offline ... I am being obtuse. In any case, there is too much fuzz in the room and the exact type of panel/diffusors going where will not be photographed (the famous midnight switcheroo) ... simply and illustration of what is being done in general.

Thanks

On the higher performance rooms we use a 240v to 120v step down transformer and balanced power for lower line noise.

I have not used a step down transformer for a whole house distributed system. However, given adequate capacity, everything in the rack, the projector, and amps for the primary room will be on the 240V system. A lot of potential issues are eliminated this way. Typically, non-dedicated spaces will not have a low enough noise floor to see a benefit; however, other issues such as having the sources on the main equipment power and the family room display on a different leg with a different path to ground could develop...but that is rare (60hz "hum bars" for example). I do suggest a TVSS for the whole house, and that all low voltage items external to the house (phone lines, cable, gate intercoms, etc.) be brought into the house via a grounded surge supression system.

In general, the only items placed on battery backup systems would be things like the network switch in the rack, the control processor (Control4, Crestron, etc.) and perhaps a DVR. Where power is unreliable with frequent outages or brown outs, there are 10 and 15 kva battery back up units available from several sources. When used, I plan on 15 minutes of power for the system, upon power failure detection, the control processor goes into a 5 minute delay before shutting down the entire system. The primary purpose is to provide an orderly shutdown of digital equipment and a proper cooling cycle for the projector. We do see an inordinate amount of component failures in areas where power failures are relatively frequent and the home has a back up generator. Those can be really nasty from time to time.

The EquiTech in this installation has surge and GFCI in the box.

In the end, your best protection is a good homeowner's policy.
