Our Projects




Analogue Video is on its way out (or in many cases totally out) and Digital Video is here.

We just got used to connecting all our video from our laptop or PC via a 15 pin D connectors. We installed scalers and splitters and everything is running fine. But we have a problem. All connections are now moving over to digital and itís using mainly HDMI connectors. The world is moving towards digital video for quality, definition and resolution reasons but with it comes many compatibility issues.

Standard HD is also referred to as 1080P. On such a picture there would be 1920 pixels in the width of the screen and 1080 pixels from top to bottom. That means 1920 x 1080 pixels or a total of 2073600 pixels. And 4K is already available which is 4 x 1080P. So unfortunately or fortunately we have to switch over.

We ran into many issues with HDMI because we found many companies and dealers are "trying out" various products and they do not all "speak" to each other.

One major advantage of going to digital is that video and audio could be routed very cost effectively over relatively inexpensive CAT 5 or CAT 6 network cable. There are also products available that makes it easy for systems to be controlled over the same network. Some systems also run over a current network without interference to the current network traffic. The main issue is the terminations. That is the little boxes ( or sometimes slightly larger with more functions) at the ends of the network cable to accept the HDMI in, distribute it over the network cable and then send it out again on the other end into our equipment. Some types could be configured into complicated wired or wireless networks of many sources like for example PC's or DVD players. And then again many fixed screens or portable devices with fancy controls and routing to display the information.

Please contact us for further details because you will need to plan to move to digital right away if you make use of video for your presentations or information. Portable or permanenly installed.

Just when you think you have seen it all comes along steerable array loudspeakers.

We all know loudspeakers. They have a certain horizontal and vertical dispersion and when you put them down or fly them you need to aim them. All of them. That is to cover the area you need to cover. BUT! Unfortunatly they also projected unwanted sound just about all over in a omni directional patern All normal loudspeakers does that. Normal band and church speakers. PA or HiFi speakers. We try to aim them as best as possible.  Line array and column array loudspeakers works a bit better and play more accurately where you aim them. And since they have a very narrow vertical angle, you need to aim them very carfefully. But they can "cut" through bad reverberant and ambient noise fields better than "normal" speakers.

When you aim speakers up or down there is a delay between the top part of the speaker unit and the bottom part. You cannot hear and you cannot see it but it happens. Some clever guys didnt like that. They knew about it and it bugged them. And they figured it out. Steerable arrays hang dead straight towards the horizon. Meaning vertically straight down. No angling down. It contains many channels of DSP (Digital sound processors) and special amplifiers and it can bend sound the up or down and also change vertical dispersion angle to only cover the listeners. Not the walls or the ceilings. So the main idea is to aim sound only at listeners. Nowhere else. It bends the complete sound wave (ok about 600 hz to 200 khz)without the delays etc. They sound amazing. Even in the worst sound environments. At the moment they are expensive. In the mean time we recommend using some kind of array. We make use of a few types. It is all about accurately aiming sound and not spilling sound all over. Normal loudspeakers cannot do that. Normal speakers were OK up to now but since arrays, column arrays and line arrays came out and now steerable arrays, we know better. Normal loudspeakers are second best.

Please contact us for further information for any of your Audio, Video, Lighting or related enquiries.

Please check this link. BELLAGIO FOUNTAINS. We supply and install the equipment that is used in this installation. This company makes products to automatically play and control audio, video, lighting or whatever you want to switch on and off for example your water fountain. They also do GPS triggered audio and video equipment for your boat, bus or even helicopter. It would play certain files when you get to a certain area or point. Our latest installation is a multi audio file playback system installed on Robben Island. Please contact us. We will recommend, design and install a system according to what you need.
