Lexicon 300L - REV Owner's Manual page 60

DIN (Digital Input Connector)
Specifying the Digital Input connector should be done before setting the 300L to
receive Digital Word Clock. Use the slider to specify XLR, RCA, or OPT
connector. All three connector ports can be occupied, but only one can be
selected to be the audio source for the system.
INP (Input — Analog and/or Digital)
Before moving this slider, be sure to identify the type of input connector which
will be receiving digital clock with the DIN controller. In SINGLE and CASCADE
Setups there are three choices: ANALOG, DIGITAL, or ANA + DIG. If you select
DIGITAL, and the system is properly locked, the Input field will briefly display
either "AES" or "SPDIF". If the system is not properly locked to the incoming word
clock, the message "!BAD DIGITAL WORD CLOCK!" will be displayed. If you
see this message, check your cables.
When a Dual-Mono setup is running, the selections are: ANALOG, DIGITAL,
ANA-A DIG-B, and ANA-B DIG-A.
When a Cascade Setup is running, the selections are ANALOG or DIGITAL.
OUT (Output Types and Patch Points)
The 300L is typically operated with active analog and digital outputs. In the Dual-
Mono and Cascade modes, however, there are other options. When ANALOG
inputs are selected, the DIGITAL outs and ins are available as patch points,
either pre or post processing. Likewise, when DIGITAL inputs are selected, the
ANALOG outs and ins are available as patch points. Cascade setups have the
patch point resource available mid - DSP as well. The OUT slider accesses the
patch points. Similar to a "half-normalled" patch bay on a mixing console, the
outputs are always active. Selecting a patch point effectively breaks the normal
and requires a return input in order for the unit to continue passing audio.
OFMT (Digital Output Format)
This slider allows you to select AES (professional) or SPDIF (Sony/Phillips
Digital Interface) (consumer) as digital output formats.
Page 2 in the Control mode allows you to set the Analog I/O emphasis and de-
emphasis curves, the digital emphasis bit and the SCMS output bit. Only sliders
2, 5 and 6 are active.
ANA: EMPH
ANA:EMPH (Analog emphasis)
Slider 2 sets analog emphasis and de-emphasis. This function is tied only to the
converters. As an example, if, when using the 300L as an A to D, you acoustically
set emphasis ON, make sure you set DIG: EMPH to YES with slider 5.
DIG: EMPH (Digital Output Emphasis bit)
Slider 5 sets the digital ouput emphasis bit ON or OFF. The top line indicates the
status of the digital input emphasis bit.
