Get Room Acoustics Right For Better Sound

Many may not realize it. But your room is the biggest audio component in a home theater setup. It will make the most difference to the sound. Do it right, and you will get natural balanced sound that you will enjoy indefinitely. On the other hand if the room is not suitable for audio playback, no matter how much you spend on a home theater or sound system it will not sound good.

Room Acoustics

Granted, there are some things in the room that you can’t change or have no control of, for eg the room’s dimensions. But if you are looking for a new home or building one, you might want to pay attention to how room dimensions affect acoustics, especially if your AV room is small. All rooms have peaks and nulls at low frequencies below 100Hz. This has a profound effect on the way low frequencies for movies and bass in your music will sound. If your listening seat is where low frequencies peak you will get severe bass boom which can be downright uncomfortable and definitely fatiguing if you are listening to music or watching movies for an extended period. Generally avoid a square-sized room if you want good bass.

If you can’t have the luxury of changing room dimensions, the next best option is applying room acoustic treatments. Some of these are common sense and inexpensive. Like placing a thick rug between your screen and your listening seat. Thick curtains will help to contain bass boom and large canvas paintings on the walls will help to reduce high frequency fatigue.

If you have the budget for professional room acoustic treatment here are some recommendations:

2. Michael Green’s Room Tunes

3. RPG Diffusers

Their new receiver range for 2013 speaks the same language and pushes all the right buttons with forward looking features.

The new models are the Harman Kardon AVR 1510, AVR 1610 and AVR 1710 priced from $299 to $549. But what can you expect at these entry level prices? Well more than what we’d expect. These receivers features 4K passthrough, 3D playback, Bluetooth, Apple AirPlay, vTuner Internet radio, Roku Ready MHL support, wide range of connectivity options, and more.

On the audio front the new HARMAN NSP Natural Sound Processing aims at recreating a realistic acoustic event, as claimed by HK. Amplification is boosted by a new switch mode digitally based power supply which provides uninterrupted power to deliver ample current for demanding movie soundtracks as well as natural timbres for music videos.

You can control the functions and menus by using the free Harman Kardon remote app for iOS® and Android™ smartphones.

Being environmental friendly is one of Harmon’s design concepts. By utilizing the new HARMAN GreenEdge™ technology which uses digital power supply to improve efficiency, dramatic energy savings can be realized without compromising on performance.

Marantz Launches New Range of High End AV Receivers

Marantz has just launched 3 new high end models in its SR line of A/V receivers replacing last year’s ‘007 series’. They include cutting edge features that will delight both audiophiles and home theater enthusiasts.

The three new receivers are already shipping. These are:

1. Marantz SR5008 (MSRP: $899) – a networked 7.2 channel receiver rated at 100 watts into 8 ohms for each of the 7 channels. It comes with Dolby Pro Logic IIz decoding, so you connect front height speakers for fuller surround and the latest Audyssey MultEQ XT for automatic room acoustic measurement and correction.

2. Marantz SR6008 (MSRP: $1199) is also a 7.2 channel unit with a higher power rating of 110 watts into 8 ohms for each of the 7 channels.

3. Marantz SR7008 (MSRP: $1999) – has 9.2 channel outputs. This is the flagship model and has a higher power output of 125 watts into 8 ohms for each of the 9 channels, enough to fill a large living room with earth shattering sound.  For room correction it has the top of the line Audyssey MultEQ XT32 to create the smoothest and most natural tonal balance.

All of these top end receivers come with 4K Ultra HD Scaling and Pass-Through and Marantz’s proprietary HDAM (Hyper Dynamic Amplifier Module) technology. Other upgrades in the SR Series include improved speaker terminals and a very user-friendly setup with a wide range of configuration options. They also support AirPlay which lets you wirelessly stream music from your iPod touch, iPhone and iPad and it also lets you access your iTunes content on your PC or Mac via your home network.  As with all modern receivers you can control the functions using your favorite iOS or Android smartphone via the free Marantz Remote App.

One thing we like is that these receivers come with detachable power cords. This allows you to have the option to use a better after-market power cord instead of the stock cord. We have found that using better made power cords on higher end models do have a noticeable improvement in audio quality.

New Kid On The Block : Sherbourn SR-8100 AV Receiver

There is a new kid on the block in the audio visual industry – Sherbourn. Sherbourn, a Jade Design company and sibling to the Emotiva brand, recently released a series of home theater gear with the goal of bringing professional performance to consumers. The Sherbourn SR-8100 AV receiver might be a new kid in this highly competitive industry but it sure is no shoo over.

Sherbourn SR-8100

The Sherbourn SR-8100 is a multi-channel receiver with the requisite power for driving 7 full sized speakers. It sports a balanced subwoofer connection, 7 channels of amplification with a switchable back/height/front biamp/zone 2 option, a 7.1 analog audio input, 4 HDMI inputs, 1 HDMI output, 2 trigger outs and a whole bunch more.

Considering it is sibling to Emotiva, this machine sure doesn’t disappoint with its great performance. While its appearance seems dwarfed and incompetent before most full-sized receivers like the Onkyo TX-SR706, this AV receiver is not one to be trifled with. Folks looking for a solid av receiver with a high performance processor can certainly consider the Sherbourn SR-8100.

HDMI 2.0 : Is It Here?

In recent weeks, talks have been rife about the impending launch of HDMI 2.0 and while new technology is usually received with open and welcome arms, especially when HDMI 2.0 would usher in a whole new era of video, it could also open Pandora’s box and create handshake issues as HDMI 1.0 did before.

HDMI 2.0 is said to not only go beyond 1080p like the current HDMI 1.4 spec does. It will also support Ultra HD at higher frame rates and support increased bit color, be it 10- or 12-bit color. While an increase from 8-bit to 10-bit color doesn’t seem like such a big deal, it actually means an increase of billions of colors that the untrained eye will be able to see and appreciate. Add that to the “four times the resolution of 1080p” that Ultra HD offers and the increased frame rate and you will see a significant step up in performance that would have people wanting to upgrade their HDTVs and equipment.

Yet another key upgrade that the grapevine seems to have paid attention to is the move from H.264 to H.265 which is said to allow for better image quality from a much more compressed file. This is big news for cable and satellite providers who are unwilling to sacrifice any single channel to make room for Ultra HD channels.

With all that said, there is really no need to fear HDMI 2.0. HDMI 2.0 is more for those who want to make the move to Ultra HD and it is still too early to say what HDMI 2.0 will bring to the table.

A Modern AV Receiver At Last?

AV receivers are known to be somewhat out of sync with modern technology and are always bulky and hard to use.

Sony has recently announced the Sony STR-DN1040, one of the most feature-packed AV receivers available for a most affordable price. Packed with built-in Wi-Fi, Bluetooth, AirPlay support, and eight HDMI inputs, what more can we ask for?

If you are a lil shocked by its price and still find it too expensive despite its undeniably nice package of features, have a look at the Sony STR-DN840 which also maintains the wireless connectivity but is a fraction cheaper.

New Denon AV Receivers Announced

While the AVR-X500 lacks the network-enabled features found in its superior counterparts, it has the same convenient front HDMI input and three rear HDMI inputs.

The Denon AVR-X1000 is an affordable model that features and Ethernet port, a Texas Instruments PCM-1690 DAC and support for a wide range of network services including remote control from Android and iOS devices and a front USB port which allows you to play music files directly from a USB stick or MP3 player.
