The M•SYNC supplies the clock signal for all M•AD-824’s in a 4496 frame. It is controlled by the leftmost panel on the front of the 4496. If there are no M•AD-824’s in your 4496, there will not be an M•SYNC. In this case, a LAVRY ENGINEERING logo panel takes the place of the M•SYNC panel.

For A-to D Clocking Modes, there are three options:

-For Internal Clock operation set the far right switch on the M•SYNC to INT.

There are different types of “jitter” that can affect digital systems; some become part of the recording and others don’t. Jitter in the A-to-D converter’s master clock can cause inaccuracies that DO become part of the recording. Jitter in transmission from the converter to the device it is feeding (a recording PC for example) DOES NOT become part of the recording. Therefore, Lavry Engineering recommends that you operate A-to-D converters on “Internal Clock” if possible.

-For External Clock operation, set the far right switch on the M•SYNC to one of two external sync modes:

WRD CLK to lock the M•SYNC to an incoming external word clock signal. The lock condition is indicated when the lock lamp illuminates.
AES to lock the M•SYNC to an incoming external AES Sync signal. The lock condition is indicated when the lock lamp illuminates.

-The SYNC IN BNC connector is for feeding WORD CLOCK and AES SYNC signals to the M•SYNC.
-The SYNC OUT BNC connector is for supplying WORD CLOCK from the M•SYNC to external devices.
-There is a 2X SWITCH on the M•SYNC rear panel near the BNC connectors. Select “ON” to enable the unit to receive standard sync rates (42-50 kHz) while facilitating conversion at double speed (84-100 kHz).
-PLEASE NOTE: The M•SYNC is NOT internally terminated.
