B.) M•SYNC OPERATION
INTERNAL CLOCK OPERATION:
Set the right-hand switch on LavryBlue M•SYNC to “INT.”
The
Narrow/Wide
switch has no effect when the M•SYNC is set to “Internal” operation.
The “Lock" lamp does not illuminate during Internal Clock operation.
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 and 96 kHz, and to
Low
for 44.1 and 48 kHz.

EXTERNAL CLOCK OPERATION:
Set the right-hand switch to “WRD CLK” or “AES.”
The unit locks to a signal applied to the rear panel
BNC
connector labeled “
SYNC IN
.”
-WRD CLK
locks the M•SYNC to incoming word clock. When lock is achieved, it is indicated
by the
LOCK
lamp illuminating.
-AES
locks the M•SYNC to an incoming AES signal. When lock is achieved, it is indicated by the
LOCK
lamp illuminating.
The use of “AES BLACK” for AES Sync is recommended, whenever possible. This is an AES
signal with all of the audio data set to “0” or in other words “Mute.”
Setting the WIDE/NARROW switch to
NARROW
provides a +/- 150 PPM lock range. Use this setting
for
standard sample rates
: 44.1, 48, 88.2, & 96 kHz. In
Narrow
mode, the incoming Sync signal’s sample
rate MUST MATCH the settings of the M•SYNC to “Lock” (see Sample Rate Switch Positions- above, and
2X Switch- below).
Setting the WIDE/NARROW switch to
WIDE
and the HIGH/LOW switch to
LOW
provides external
clock operation in the 42-50 kHz range.
Setting the WIDE/NARROW switch to
WIDE
, and the HIGH/LOW switch to
HIGH
provides external
clock operation in the 84-100 kHz range. The rear panel
2X switch
must be “OFF” for this configuration.
-When in
NARROW
lock, one frequency indicator lamp shows the selected output rate.
-When in
WIDE
lock and
LOW
, the top lamps (44.1 and 48 kHz) are lit simultaneously to
indicate 42-50 kHz range.
-When in
WIDE
lock and
HIGH
, the bottom lamps (88.2 and 96KHz) are lit simultaneously to
indicate 84-100 kHz range.
