Getting Started Mark Levinson Special Design Features As seen from the rear panel, perhaps the most obvious characteris- Modular Design tic of the Nº40 is its extraordinary modularity. Both the audio processor and the video processor are built on “card cage” designs that maximize hardware flexibility now and in the future. While more costly than an “everything on one board” approach, the extensive modularity of the Nº40's design is the best and most logical response to the rapidly-changing

So, on top of all this standard capability, we have left several “slots” open in each processor for future appli- cations, which may

Getting Started Mark Levinson Sound profiles capture the many characteristics you can define for a particular activity, and make them available at the push of a button. In fact, you can even set up the Nº40 so that you need not even push the button. Instead, you can associate a profile with either a particular type of audio signal (for example, 96 kHz PCM, Dolby Digital, etc.) or with a particular input (for example, CD, VCR, DVD, etc.). With a little creativity, you can readily have the s

Nº40 Media Console Getting Started Significantly, this remarkably effective jitter-rejection circuitry is used for all digital signals, on all paths. Remote and record zones also benefit from the sonic improvements of the Intelligent FIFO. Digital processing Digital processing of the signal in the main zone is performed by four powerful SHARC DSP chips. These DSPs perform 32-bit fixed point processing as well as 32-bit and 40-bit floating point process- ing. This compares rather favorably wi

Getting Started Mark Levinson Digital to analog conversion Digital to analog conversion is also done at an extraordinarily high level, as you would expect. The main zone uses a special Levinson- developed implementation of the Analog Devices AD1853, a new multibit Sigma/Delta converter. In fact, each of the eight main output channels uses two fully balanced channels of these DACs, in a dual differential configuration. The output of these DACs is then converted from current back to a voltage

Nº40 Media Console Getting Started Movie sound tracks are mixed in special movie theaters called dubbing stages, and are designed to be played back in movie theatres with similar equipment and conditions. This same sound track is then transferred directly onto Laserdisc, VHS tape, DVD, etc., and is not changed for playback in a small home theater environment. THX engineers developed patented technologies to accurately translate the sound from the movie theater environment into the home, c

Getting Started Mark Levinson In a movie theater, film sound tracks that have been encoded with Dolby Digital Surround EX technology are able to reproduce an extra channel which has been added during the mixing of the program. This channel, called Surround Back, places sounds behind the listener in addition to the currently available front left, front center, front right, surround right, surround left and subwoofer channels. This additional channel provides the opportunity for more detail

THX Ultra2 provides the Boundary Gain Compensation (BGC) feature to provide an improved bass balance. THX Ultra2™ Before any home theater component can be THX Ultra2 certified, it must incorporate all the fe

Getting Started Mark Levinson The analog backplane, as discussed, rivals the finest matrix switch- ers used in the professional video world. In addition, the Nº40 has a standard definition digital video back- plane, and a dedicated high definition digital video backplane. The standard definition digital video backplane is used for routing transcoded video signals within the Nº40 (more in a moment), and for our digital graphic user interface. In all, there are over 2000 “nets” (connections)
