Control Mode; Word Clock - Lexicon 960L Owner's Manual

960L

CONTROL MODE

The LARC2's CONTROL key provides access to the 960L's
Word Clock, input/output configuration, and system infor-
mation. The faders and joystick remain assigned to what-
ever audio parameters are on the V-Page.

Word Clock

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.
Use the Right Navigation Arrow to get to the Rate display.
For internal Word Clock, you must select the exact rate, as
shown in Fig. 4-3. For external Word Clock via the BNC or
AES inputs, you need only select 44.1/48 kHz or 88.2/96 kHz
range. The 960L will then lock onto your source.

Note:
Use of the internal Word Clock 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 Word Clock.
• Allow the 960L to slave (BNC or AES) to the
digital source's Word Clock.
• Slave the digital source to the 960L, using the
960L AES or BNC output.
