De-Emphasis Menu Up
The De-Emphasis button is also triple function – on its own, it sets the De-
Emphasis characteristic. If the “Panel” option, page 23. is set to Volume, it
functions as the Volume up button. With the other menu buttons, it is the menu
Up button.
De-Emphasis is available for 32, 44.1 and 48kHz sample rates only.
Pressing the button repeatedly causes the single digit Mode display to the
right of the button to cycle through the following options:
Display De-Emphasis in Use (low sample rates)
A Automatic - the unit automatically implements the De-
Emphasis characteristic coded in the data stream.
The display changes to 5 or C when De-Emphasis is
automatically applied.
5
The unit implements 50/15µs De-Emphasis.
C The unit implements CCITT J17 De-Emphasis.
- De-Emphasis disabled.
Table 2 - Emphasis Indication, low sample rates
dCS recommend setting the unit to Automatic unless there is an error in
the De-Emphasis message in the incoming data stream.
For Menu operation as the Down button, see the section “The Software – the
Menu” on page 16.
Mode Display -
At sample rates over 48kS/s (dCS 952 only), the single digit LED Mode display to
the right of the De-Emphasis button shows the input format:
Display
Input Format
1 Single AES
2 Dual AES
Table 3 - Output Data format indication, higher sample rates
Sample Rate Display -
The main display generally shows the incoming sample rate, in kS/s. When
other parameters are set, it briefly shows the new setting (volume, tone
frequency, etc) then reverts to its normal display. In the case of an error
condition, it will display an error message.
If the unit is being slaved to a reference source, the display also indicates which
reference input it is slaved to.
