Dante Level 1 All Classes Questions and Answers Rated A+ Jitter *Distortion caused by inconsistent word clock in playout *classic problem with older "daisy chained" digital audio *Recognized as a potential problem in legacy transports like AES3 MADI or ADat in these systems the word clock is embedded in the audio signal as a start of frame message which must be unpacked From the data stream which contributes to misalignment under some signal conditions especially when connecting many devices together *classic solution here was to use an expensive external clock that would slave each device thus forceing a clock alignment between them. *dante uses a highly accurate clock synchronization method Latency *Audio Signal delay in a system *Transport and processing of audio signals *Mainly a problem when we hear delayed and undelayed signal simultaneously * How fast does sound travel 1128 feet per second or 343 meters per second How to find audio bandwidth Multiply the sampling rate by the bit depth Ex. 48kHz (48000 hertz) is the sampling rate and 24 is the bit depth. 48000 *24 =1.152 mbits/sec (megabits per second) per channel if there is more than one channel multiply the number of channels by the sample rate and the bit depth. Ex. you have 64 channels of audio, a sampling rate of 48kHz and a bit depth of 24 48000 *24*64 =74 SFP switch Small form factor plugables EEE Energy efficient ethernet Or "green" switches are not a good choice for real time media the energy saving feature will shut down ports and prevent parts of dante from working properly Horizontal Channels in Dante are ________________ Transmitters Vertical Channels in Dante are _____________________ Receivers Dante Connections are called _______________________ Subscriptions
