Model m • ad-824 analog-to-digital converter and m • sync quick-start guide version 2.0
M•ad-824 quick-start guide 1 overview- the m•ad-824 is a two-channel module that converts analog audio to digital audio with wordlengths of 16, 20 or 24 bits at sample rates of 44.1, 48, 88.2 or 96khz. The m•sync module provides either internal or external clock operation for the m•ad-824, and can g...
M•ad-824 quick-start guide 2 3.) select the desired sample/clock rate on the m•sync . The m•sync is controlled by the left-most panel on the front of the 4496. The 2 left switches set the sample frequency for internal clock and external clock- narrow mode. The high/low switch is set to high for 88.2...
M•ad-824 quick-start guide 3 - for external lock, use the narrow/wide switch to choose which type of lock mode is best suited to accommodate the clock source: choose narrow to reduce the sampling frequency input range to lock to signals within +/-150ppm (parts per million) around a fixed rate (44.1,...
M•ad-824 quick-start guide 4 6.) select the desired word length (16, 20, 24 bit). Enter program mode and the word length lamps illuminate (the first function in the list). To set the word length , toggle “up” ( set ) until the lamp next to the desired word length stops blinking (16, 20, or 24 bits)....
M•ad-824 quick-start guide 5 8.) select dither & optional noise shaping for 16 bit or 20 bit modes. Dither, abc-1 and abc-2 are grouped together (similar to word length). αβc αβc αβc αβc α coustic β it correction® is dither plus psycho-acoustic enhancement of the converter’s dynamic range for word l...
M•ad-824 quick-start guide 6 2.) it is easiest to feed the reference tone to the mad module before switching to reference mode to establish what level it will appear on the mad meters. For example- use a tone at “0 dbvu” from an analog source or “-12 dbfs” from a digital source feeding a da converte...
M•ad-824 quick-start guide 7 you need to know . . . About master-slave modes – a module may operate in either master or slave mode. All the slaves copy parameters set on the master. A master module is usually located in the leftmost chassis position and set to “master” via the on-board dip switch (p...
