 *The MAD-824 will not un-mute unless it is receiving a valid clock signal from the MSYNC. This will only occur when the MSYNC is set to "Internal" or when the MSYNC Lock indicator is illuminated in external sync mode (Word Clock or AES). If with a "known-good" analog signal connected to the inputs, the MAD-824 does not appear to pass a signal (no activity on front panel meters and digital output is muted), check that the MSYNC is either set to "Internal" or that the Lock indicator is illuminated.
 *If you cannot get the MSYNC to show "Lock" to an external 88.2 or 96kHz sync signal; double-check the setting of the rear panel 2X switch to be certain it is "Off."
-* The BNC Word Clock input of the MSYNC IS NOT internally terminated. Although in most cases termination is not necessary with short cables in point to point connection (the signal is not “chained” to other slave devices); if you experience problems getting the MkIII to lock to a “known-good” external BNC Word Clock signal, a [[BNC “T”]] should be placed on the Word Clock input of the MKIII and a 75 Ohm [[BNC terminator]] placed on the “T” opposite the incoming Word Clock cable to provide termination. External clock units that have termination “auto sensing” often require the AD122-96 MkIII’s Word Clock input terminated to function properly.
+* The BNC SYNC IN of the MSYNC IS NOT internally terminated.

External clock units that have termination “auto sensing” often require the MSYNC SYNC IN  be terminated to function properly.
 *When employing “input clipping” to achieve elevated digital levels with the MAD-824, use of some front panel Gain is recommended to avoid overloading the analog input stage prior to the input of the AD converter stage. For example; if the input level will exceed +24[[dBu]]; it is recommended that the minimum amount of gain corresponds roughly to the number of dB’s the input level would need to exceed +24dBu with the factory setting to achieve the desired amount of “clipping.” By increasing the Gain, the input level will remain below +24dBu and still result in the desired amount of “clipping” without overload at the input stage.
 *If the MDA-824 does not appear to be functioning properly when fed from an external source (normal operation), try temporarily connecting the MAD-824 AES output directly to the MDA-824 AES input using an XLR cable. With the MSYNC set to "Internal;" the MDA-824 front panel "Lock" indicator should illuminate and the displayed sample frequency should follow the SF settings of the MSYNC.

 There are instructions on disassembling and re-assembling the 4496, including important details like the fact there are two different types of screws holding the front panel in place. Please use the longer conical head screws only through the rack ears and the shorter undercut head screws in the top and bottom covers.
