The 300L, as shipped from the factory, is set to run Analog In at 48kHz. To
change the Analog Sampling rate, to slave-lock the 300L to an external digital
device, or to external system word clock, press CTRL to enter the 300L Control
mode. The first page defines the input and output structures of the 300L.
STA CLK DIN INP OUT OFMT
This page allows you to view the current status of the box, (STA), define sample
clock speed (CLK), specify a digital Input connector (DIN), and select Input type
(INP), output type (OUT) and digital output format (OFMT).
STA System Status (View only)
This slider lets you view (but not change) the current status of the system
parameters.
CLK Analog Clock Rate
Press the button under the slider to show the current analog clock sample rate.
Use the slider to select a new clock sample rate. If a Digital clock has been
selected to master the 300L, the display will show the current sample rate.
DIN Digital Input Connection
Before setting the 300L to receive Digital Word Clock, use this slider to designate
one digital input connector ( XLR, RCA or Optical) as the master for the system.
You can have all three connector ports occupied, but only one can be selected
as a master and audio source.
INP Analog, Digital, or Both
Identify the type of connector which will be receiving digital clock (via DIN), then
select the Input type here. In SINGLE Setups there are three choices: ANALOG,
DIGITAL, or DIGital. Use the slider to select the type of input you wish
to use. If you select DIGITAL, and the system is properly locked, the display field
will briefly show “AES” or “SPDIF” to indicate the format of the incoming signal.
If the system does not detect valid word clock, or is not properly locked to
incoming word clock,a "BAD DIGITAL WORD CLOCK" message will be dis-
played as shown below. If you get this message, check all your cables, and other
settings.
