Lexicon 960L - Manual (Page 34)

960L Owner’s Maunal Operations in Detail
The LARC2’s CONTROL key provides access to the
960L’s wordclock, input/output configuration, and
system information. Note that only three soft buttons operate in this mode. The faders and joystick remain
assigned to whatever audio parameters are on the
V-Page.

Wordclock
From the Control Mode screen, press the WORDCLK
soft button, then the number of the source you want:
1 Internal Crystal-controlled. Use only with
analog inputs, or if your digital inputs
are from sources that are locked to
the 960L.
2 BNC For locking to your studio’s
master clock. Used with
analog or digital input.
3 AES Clocked from AES input 1-2. Used
with analog or digital input. Note that
if you are using AES as both the
clock and audio source, and
disconnect AES input 1-2 (the clock
source) while other inputs remain
active, you will hear artifacts on the
non-clock channels, while the system
detects the disconnect.
Entering the clock source number will select that
source. You can also select a source with the Up/Down
Navigation Arrows or the Increment/Decrement (+/-)
keys.
Note: Use of the internal wordclock with digital inputs
can introduce audible artifacts due to sample slip, even
if the nominal sample rates are the same. When the
960L detects slipped samples in the AES input stream,
the audio outputs are muted. To avoid this, do one of
the following:
• Slave both the digital source and the 960L (BNC or
AES) to a common wordclock.
• Allow the 960L to slave (BNC or AES) to the digital
source's wordclock.
• Slave the digital source to the 960L, using the
960L AES or BNC output.
