Encore Two User Manual Issue 1Processing ElementDigital console have a certain amount of processing power available.This depends on the number of signal processing cards in the main system rack. Each signal path usesprocessing power and adding audio processing to a path, such as EQ or dynamics, uses more processingpower. Anything that applies changes to a signal in a path uses processing - this even includes the fader.A processing element is one of the individual items of audio processing that can be assigned to orremoved from a signal path (e.g. fader, compressor, three band equaliser, etc.).The processing elements are allocated to the signal paths in advance of being used. This reserves theprocessing power and prevents resources from being overloaded.The information about which processing elements are assigned to each path is stored as part of the DeskSetup.Quad-Madi II cardEach Quad-Madi II card has 4 pairs of madi ports, each pair consisting of one Transmit port (Tx) and oneReceive port (Rx).These pairs of ports are usually accessed from the back of the SPS rack (or they can be accessed fromthe front of the card itself (the upper port in each pair is Tx).QuadMadi cards bring madi signals into the system and place the data on the backplane where theXSP cards can access, process, and then return this information.QMII cards are available in three versions, depending on the amount of assignable delay required(none, 5secs total or 10secs total).The card is also responsible for:• Assigning Delay to a signal, either on Input or Output.• Generating most (if not all) of the meter data seen on the meter bridge and fader beds.• Dither on Outputs.• The system timing, ensuring all of the XSP processing cards run in sync.QuantisationQuantisation is an effect of converting analogue signals to digital signals.For instance, a pure sine wave is sampled at the system sample rate (usually 44.1kHz or 48kHz),creating a series of stepped values (the level at each sample point along the wave form) which produce aclose approximation of the sine wave.However, if a wave is at a very low level, the smallest step size (or quanta) can become significant sothat the approximation of the wave is inaccurate. This is when quantisation can distort a signal.A solution to this is to dither the signal on output and this has the apparent effect of smoothing thestepped values.Radio ButtonUsed to select only one option from a limited list of options.Only one radio button in a set can be selected at a time.Selecting a radio button automatically de-selects the previously selectedradio button.- 14 -
