home cinema explained multi-channel although stereo systems two speakers giving the possibility of left to right staging have been around for some years multi-channel systems are a more recent development originally just for full size cinemas multichannel systems set out to create a wrap-around sound `stage allowing sounds to move both left to right and front to back home cinema receivers and processors decode signals from various sources and then feed six or even eight speakers with the appropriate sounds to create these effects speaker positioning unlike stereo multi-channel surround sound is mixed for a known listening environment the cinema this means for the best results in the home all we need to do is replicate the correct speaker positions according to the rules set down by the recording industry arcam s award-winning training program gives its dealers these skills and they are best placed to advise on speaker positioning for your room universal playback in recent years a multitude of disc formats have arrived and are now available on dvd players these formats have a variety of advantages and cover both music and movie playback the term `universal has been loosely adopted in recent times to indicate that a player is compatible with all common formats these are generally understood to be dvdvideo cd dvd-audio sacd vcd and s-vcd although at arcam we believe that performance for dvd video and cd discs is of prime importance our models have a variety of disc playback possibilities and now includes universal playback on the dv137 low frequency effects thrilling movie playback demands much of an audio system one of the most difficult things to achieve is deep and controlled bass the explosions bangs and crashes that litter today s typical action movies are a good example with this in mind digital surround sound often carries a dedicated track for these called a point 1 or low frequency effects lfe channel in systems with a dedicated sub woofer the bass portion of these effects is only replayed by the subwoofer itself which is designed to handle these types of signal video scaling although video pictures are made up of a fixed number of horizontal lines for example 576 for pal in europe 480 for ntsc in north america most digital displays plasma lcd dlp etc use a larger number of lines to fill the screen because of this incompatibility video scaling devices that mathematically work out how the picture should look on this larger number of pixels are required fitted inside the screen the quality of such devices varies widely the dv137 incorporates ultra-high performance video scaling devices fitted to take over from those fitted in the screen resulting in a vastly better picture p1000 power amplifer the p1000 7-channel power amplifier is rated at over 135 watts per channel it uses an innovative class h amplifier topology that offers high current capability with cool running operation the p1000 and the avp700 represent a home cinema as you would expect from arcam s audiophile heritage great emphasis has been put on achieving a level of sound quality that is clearly better than the competition combination that convincingly brings music and movies to life building on the reputation arcam has for producing products that set the standard 7
