RIGHT side of each module’s PC board. The audio XLR inputs of the M•AD-824 are electronically balanced line level (nominal +4dBm). In order to maintain good noise rejection qualities, Lavry Engineering recommends that you use balanced inputs for unbalanced sources as well. - Page 3 M•AD-824 Quick-Start Guide 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.
- Page 4 M•AD-824 Quick-Start Guide - 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, 48, 88 or 96kHz). Narrow lock operation provides improved jitter rejection when operating with a known fixed frequency.
- Page 5 M•AD-824 Quick-Start Guide 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).

M•AD-824 Quick-Start Guide 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 αcoustic βit Correction® is dither plus psycho-acoustic enhancement of the converter’s dynamic range for word length reduction to 20 or 16 bits. -

M•AD-824 Quick-Start Guide 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 converter. - Page 8 MicPre’s are doublewide modules, and take up two “slots.” Lavry Engineering is required to install the first M•AD-824 module and MSYNC in the 4496 chassis. There are a number of critical calibrations that are part of this procedure. Your dealer can provide assistance or contact Lavry Tech Support: techsupport@lavryengineering.com...
