All Home theater audio video and electrical cables are laid directly inside the room with just the Internet and Tata Sky connectivity wires brought from outside.

Since India undergoes a lot of power fluctuations, save your Home theater electrical equipments from damage by installing an efficient power conditioner.

Moreover, an air conditioner protects the amplifier from damage by keeping its temperature under control. For the same, make provisions for AC ducts after consulting a Home theater expert in terms of installation, internal lining and sound proofing. The general Split and Cassette AC’s can also be used as long as they produce low self-noise.

10. Home theater Automation:

The active Jamo D600 subwoofer requires a pre-output through a moulded RCA cable through which it is connected to the AVR. The projector, apart from the power cable, will need a HDMI cable and an optional CAT6 cable for Home theater automation purpose.

After completing all the physical connectivity, you can tune your audio systems through professional Home theater calibration software like REW or a handheld Audio Analyser.

There are several other parameters to be looked at such as setting the right sound pressure levels, audience to Speaker distances and audio equalizations which must be of top priority along with the subwoofer placement and output optimization.
