High definition or HDMI is the latest method of transporting stunning high resolution picture and true mind blowing 5.1 surround sound from a source device like our HD PVR decoders or Blu-ray players to our HD televisions or AV Receivers.

HDMI is limited as each source device is generally only supplied with a relatively short HDMI cable of approximately 1-2 m in length for connection to only one output device, AV Receiver or TV.

Many homes now days have more than one TV

and would like to be able to view the high definition signal, or signals from multiple sources on more than one TV at  a time.

High definition cables have certain limitations:

HD cables, especially quality ones, are expensive.
They are relatively bulky to install and cannot be cut, they must be purchased in pre manufactured lengths.
HD cables can  only  be run up to a maximum length of approximately  10 metres.

HDMI splitters enable us to plug in one HDMI source like a  blu-ray or HD Decoder and send that signal to multiple  devices, TV  or AV Receiver for simultaneous viewing on all the connected devices, as  it only splits the signal all devices can  only view what is  being broadcast  from the one source. To  be able to view more than one source on multiple TV’s requires a different device.

As discussed earlier HDMI cables are intended for short distances only, but in many cases the  source may be quite far from the output device, in this case  we make use of HDMI extenders, these devices receive the HDMI cable from the source on one end then convert that signal  to a cat5/6 output  which can be run up to 50m depending on broadcast signal type and cable quality, the cat5/6 cable then connects to a receiver which converts the signal back into HDMI for connecting to the TV or AV Receiver. 

Cat5/6 cable is much smaller and more flexible than HDMI cable and  can therefore be more easily installed through pipes and  conduits.

Many homes not only have multiple TV’s but may also have numerous High Definition sources, HD PVR’s, blu-ray players etc which they may wish to be able to view on demand on any TV in the home. This requires the use of an HDMI matrix switcher which can receive multiple HDMI inputs and switch these inputs on demand to any selected output for viewing on that specific TV. These devices also offer infra-red throughput for controlling of the source device from any connected point in  the home using the source devices remote control.

We have researched many multi-room audio systems over the years and the wireless Sonos Multi-room audio system, for many reasons, has proven time and again to be the best multi room audio system.

Despite being the best multiroom audio system it is also one of the most affordable, not just the products, but installation costs are minimal. The system generates it’s own wireless mesh network and requires virtually no wiring, which makes it perfect for existing homes as well as new builds. So easy you could do it yourself with a PC, broadband internet and a little networking knowledge.

We can however offer many other multi-room audio systems, just give us a call if you have a particular preference.

Modern Home Theatre systems require comprehensive knowledge of:

HDMI technologies, High Definition Multimedia Interface, all modern home theatre systems utilise HDMI for superior video and sound quality, in fact Audio/Video devices will soon no longer be manufactured with the old analogue style inputs. HDMI requires specialised knowledge to setup and install correctly, especially if you wish to distribute true high definition signals to multiple output devices, like multiple screens/TV’s. This will require the use of specialised distribution equipment and converters. See more under HDMI Distribution.

Computer networking and cabling for DLNA. Modern Home Theatre systems are becoming more and more like a computer and can be connected directly to your computer network, this offers many benefits, streaming of internet radio and other music services, play digital music and video that is stored on your computer network. DLNA is an international specification, digital living network appliance, all DLNA compliant devices can immediately see and “communicate” with other DLNA compliant devices on the same network.

WiFi configuration, as above modern home theatre systems can be connected to your home network via WiFi, if a wired network is not available or impractical to install.

Smart phone/pad applications, as modern home theatre systems are net workable the manufacturers have written “apps” that can be downloaded onto various smart phones and used for controlling a multitude of “intelligent” devices. As this operates over WiFi it offers improved control and portability over the infra-red remote control, which are directly line of sight and limited range.

Proper home theatre design and layout. If you are investing in a quality home theatre then you want the most out of it, poor installation and layout will diminish the surround sound effect that you will achieve. Unfortunately most rooms where home theatre systems are installed are not specifically designed for this purpose, they are different shapes, layouts and comprise of different materials all of which affects the acoustic quality, but a professional installer will be able to get the optimal sound out of your system for the conditions/environment in which it is installed, and advise on some simple techniques to improve the acoustics of a room.

Home Theatre optimisation for optimal sound quality in installed environment. Modern quality home theatre systems offer a system that can be utilised to automatically optimise the sound output to best match it’s surrounding environment by using a small microphone the system emits a series of sounds through each connected speaker and measures the feedback it receives in the microphone and automatically optimises the sound output to it’s environment.

Multi-zone systems. Many modern home theatre systems offer the ability to set up multiple zones, not just audio, but multiple video zones too. So through the one system you could be watching the rugby in 5.1 surround sound in the lounge, but listening to music on the patio through a separate pair of stereo speakers, with each zone being separately controlled.

Product compatibility between components. Modern home theatre systems offer such an array of functions and features it’s vital to ensure that all the different components are compatible with each other and will form a great overall system, there’s no point in buying the latest and greatest 3D LED TV, but your AV Receiver is not capable of processing 3D signals.

Digital audio and video codecs for compatible streaming purposes. Modern home theatre systems are capable of playing digital audio and video straight off the network or storage device, but only understand certain formats, unfortunately there are literally dozens of different audio and video codecs out there and some of these will not work on all devices, it’s important to check compatibility with your digital audio/video library before you purchase the wrong equipment.
