Phono amp is the missing link between the vinyl past and digital present

For the committed LP fan, especially those dedicated to listening to recordings of early 20th century musicians whose recordings may exclusively be available on vinyl, the shiny silver micro CD system in the corner of most modern living-rooms, perhaps purchased at an out of town supermarket, is an offence. Suggesting they listen to CDs on an audio system without phono amp or phono preamp, is like asking Raymond Blanc to subsist on a diet of Pot Noodles. In pursuit of the perfect, most authentic sound, these fans will spend much time and money on the perfect phono stage while the rest of the world looks on confused at their predilection of a so-called obsolete technology.

Although nowadays only a minority of people under the age of thirty will have bought a 78 or 45 in their time, the ability to record and reproduce sound was so revolutionary that they remained in popular use in one form or another across the span of century from the 1890s right up to the early 1990s.  Once cheap CD players became as affordable as turntables, digital music reproduction became king, but the commitment of those dedicated to ‘authentic’ music recordings is such that the technology behind and the market for turntables, phono stages and cartridges continues to develop at the high end of the audio system market.

Indeed, many purists continue to use vinyl only, suggesting that digital music systems – CDs, and MP3 downloads – give a clinical and processed sound that is second best to the records of yesterday. Others may want to continue listening to their record collection without paying out large amounts of money to purchase duplicates in digital format – and, in any case, many LPs may simply not be available on CD. The evolution of music playing has also seen an evolution in marketing and corporate strategy, and smaller parties are not economically worth updating. Consequently, vinyl editions of these artists are unique and irreplaceable.

This does not mean that vinyl cannot be combined with state-of-the-art modern sound equipment, though. You can secure the best of both worlds, linking your turntable to amplifier and speakers via a phono stage. The work of a phono pre-amp is to amplify the signal from your turntable to make it useful to the main amp; thus a phono amp is an indispensable element of listening to your old LPs on modern equipment, helping to keep the past alive without sanitising it with the vagaries of the new digital systems.

Brise soleil – cutting-edge style and practicality go hand in hand

As awareness of environmentally sound architecture increases and government regulations surrounding the energy impact of buildings become increasingly tight, many architectural features such as the brise soleil and external louvres have become commonplace, even if many people are unaware of their function. Many may assume that the aluminium curtains, glass louvres and sails which are increasingly an element of modern buildings, are just a design feature whereas their impact is far more than just decorative.

Given the popularity of programmes such as Grand Designs, the concept of passive solar heating and the use of more efficient insulation to reduce heating costs is now pretty familiar. However, the opposite effect, passive cooling, is rarely considered, even though it is a technique which was used by the Ancient Egyptians! Less thought is also given, outside design circles at least, to maximising the use of natural light in new buildings, thus reducing electrical costs. Solutions that work with the sun to provide maximum natural lighting without glare and overheating are also still a pretty avant garde concept.

However, the weird metal protrusions that stick out of many new buildings these days looking disarmingly like an over-sized set of IKEA kitchen shelves can help with both cooling and lighting concerns and many other more discreet design features, for example glass louvres, are also providing more than just a decorative function.

The term ‘brise soleil’ which, roughly translated from the French means ‘sun break’, refers in architectural speak to any permanent external structure which helps to stop the sun shining directly into a building. Some avant-garde architects have even built such a function into the main fabric of the building, such as Le Corbusier who created distinctive simply patterned concrete walls. More usually, a structure made of a different material is used, such as steel or aluminium louvres. These can be angled to allow a building with an expansive glass façade to be protected from overheating during the summer when the sun is at a higher angle while maximising the intake of light and warmth from the sun during the winter months when the light comes in  from a much lower angle.

The best firms are able to create detailed analyses of either existing buildings or the plans for new projects. These map out the angle of the sun during different periods of the year and make proposals based on these calculations for appropriate sun-shading. Maple Sunscreening, for example, is a company which regularly advises architects and engineers on how to use features such as brise soleils and glass louvres to meet standards for CO2 emissions and combines advice on internal sun-screening with suggestions for outdoor screening such as external louvres to create an overall scheme which maximises long term reductions in the final building’s energy costs.

Telepresence video conferencing uses the most advanced communications technology available

The future of video conferencing has arrived. Audio visual conferencing has progressed in leaps and bounds since its inception, which arguably dates back to the late 1930s, when the German Post Office (Reich Postzentralamt) successfully created a network in several cities. These connections featured closed circuit television systems, which were connected by cables. Since then a technique was developed, chiefly by NASA on the first manned space flights, to link televisual information using radio frequency links. This is the type of link, still used today, by news teams to deliver reports from distant locations. This kind of communication is all very well and good for high profile media presenters, or space expeditions, but it can scarcely be viable for businesses, educational purposes, or telemedicine practices: it is simply far too dear. telepresence video conferencing, as we think of it today, uses much more economical technology, and so it is much more accessible to businesses and individuals throughout the world.

A good visual link enables you to communicate remotely to the fullest extent possible – visually and verbally. But the road to having the sufficient level of technology to achieve this has not been easy, since there have been a number of difficulties that have made things hard. In the 1980s a breakthrough was made when developers used Integrated Services Digital Network (ISDN) digital telephony transmission networks to support compressed audio and visual transmissions, with some amount of success. In the 1990s, however, video conferencing built on Internet Protocol (IP) became available, which amounted to a revolution in the industry. This is because among the implications was the fact that televisual communications on personal computers was now a possibility, and the race to release a widely available software solution had started.

Today, audio visual conferencing solutions are available left, right and centre, from the free, albeit relatively low quality, Skype and iChat webcam plugin services to high-end telepresence video conferencing firms dealing with large multi-national companies. A huge range of solutions are available, and can be catered to the individual needs of any business. Video conferencing is said to be the way forward for global communications in the future, so some communications companies are competing to stay on top of the game as far as the technology is concerned. In an age where virtually everybody in the western world already seems to have mobile telephones, it seems only a matter of time before we are all communicating with mobile video technology as well.

Sales ledger manager jobs in London search need not be stressful
