May 2010: Welcome to Issue 36 of the Practical HT Guide Update
Hi, the Practical Home Theater Guide e-zine is back!
But first, apologies for not having published the e-zine for the last year or so; unfortunately, a number of unplanned commitments cropped up in the process that made it impossible for me to keep on publishing the site newsletter. Now that running this website has become my full time activity, I am in a better position to get back to publishing this newsletter on a more regular basis once again.
Audio Amplifier Power: How much power do you need?
Audio amplifier power is a much debated issue and often a grossly misunderstood term; in particular, many relate amplifier power solely and directly with speaker loudness, which is not exactly the case.
Determining the amount of amplifier power necessary to match your expected level of loudness or listening pattern is critical for both an enjoyable listening experience in the home theater, and for the safety of your gear - speakers and amplifier alike. That's correct, having adequate amplifier power reduces the risk of you literally frying your speakers out of your attempt to get more power from your audio amplifier by sending it into clipping.
The required amplifier power has to be seen in the light of both your home theater speakers efficiency and the room size. All three are equally important and need to be taken into account when planning an audio set-up.
Home Theater Speaker Placement: Optimum placement for an immersive experience.
Home theater is not just watching movies - it is the experience of being immersed into the movie action itself. This would not be possible without the enveloping atmosphere created by surround sound.
Home theater sound systems require at least five main speakers and a sub woofer, hence the reference to a 5.1 speaker playback setup. More advanced audio playback systems may feature six (6.1 setup) or seven (7.1 setup) full-range audio channels for greater realism.
Surround sound requires that the various sounds produced by the different speakers originate from specific positions within your home theater room. Knowing these requirements will help re-create the sound producers intended it to be.
Furthermore, as we further explains in our guide to Home Theater Speaker Placement, there are also distinct differences in speaker placement requirements between multi-channel music listening and watching movies.
Is it Worth Investing in 3D TV now? Discussing the challenges of 3D TV in the home
Research firms are expecting that sales of 3D HDTVs will exceed 4 million units by the end of this year - while peaking to 78 million units globally by 2015.
Yet, we believe that these predictions are a bit too optimistic when considering the challenges 3D television technology has to overcome to become the mainstream TV technology in home entertainment.
And as we will further explain in our article - Challenges of 3D TV in the Home, it is not just a matter of the present bad economy. A less immersive 3D experience, lack of 3D content, consumer reluctance to upgrade, and the burden of the 3D LCD shutter glasses, all contribute to make what some have dubbed as the greatest development in TV entertainment since color television, less fun than originally many thought it would be - at least for the time being.
