Eclipse User Manual
Release 4.0.1 Page 25 of 66 Eclipse User Manual
The Eclipse reads the digital input format and makes any adjustments that it needs to automatically, with
the exception of slaving to the digital input’s clock. Unless the device connected to the Eclipse is slaved to
the Eclipse, you will want to switch SETUP DIG-IN (CLOCK) to DigIn.
If the digital input that you select is unconnected or carries a bad signal, the EXT LED will blink hypnoti-
cally.
To find out the status of the input signal for troubleshooting or general
curiosity, press and hold the SETUP DIG-IN (DIG-IN) soft key.
Press (STATUS) to verify that the signal is being read (OK or
Data Err) and, if it is, in what format (Pro or Cns).
Press (BITS) to check the input word length.
Press (EMPHASIS) to check the input emphasis status. Emphasis is
largely a relic of early digital audio technology. The Eclipse can read and
write emphasis “flags,” but it does not code or decode emphasis regardless of
the status of said flags.
Press (SCMS) to check the copy status of the incoming audio.
The possibilities are Copy-Prohibit, 1-more, Copy OK, or N/A
(not applicable). Regardless of what the input audio SCMS flag is
set to, the Eclipse can use the audio.
Use the above information wisely…
Internal and External Clock Source
The Eclipse’s sampling rate can be derived from an internal clock source, the clock source of
the digital input selected at SETUP DIG-IN (DIG-IN), or the word clock input. Use SETUP
DIG-IN (CLOCK) to select from:
Int Use Int (for “internal”) to select from 44.1kHz, 48 kHz,
88.2kHz, or 96 kHz sampling rates. The “rate & source”
indicator pictured above will reflect your choice. Realize that the EXT LED will not be lit,
indicating that the clock source is internal. Use the internal clock if you aren’t using a
digital input or if the unit connected to the digital input is slaved to the Eclipse’s clock.
DigIn Use DigIn to use the digital input as a clock source. Recall
that the digital input is selected at
SETUP DIG-IN (DIG-IN) . The
Eclipse will read the incoming rate (~30kHz-50kHz or ~54kHz-99kHz) of the input and will
display it next to DigIn. In addition, the “rate & source” indicator pictured above will re-
flect the fact that you have chosen an external clock source (EXT will light). It will also
light the LED that most closely matches the detected rate
(signals that are way off frequency
will cause the nearest LED to blink)
.
Note: If there is no signal at the digital input or if the signal is absent or corrupt, the EXT
LED and rate LED will blink and the Eclipse will switch to the internal rate closest to the
last valid external rate.
