d&b audiotechnik D12 - Input Monitoring Menu

Input Monitoring menu
Mode
Selecting "Mode" and pushing the encoder allows the setting of the
following functions:
Analog Pilot: monitor incoming pilot signal at the analog inputs
Digital Pilot: monitor incoming pilot signal at the digital input
Digital Lock: monitor whether the digital input has locked
Input A / Input B
Selecting either "Input A" or "Input B" and pushing the encoder allows
the following settings for each channel independently.
Mode
Selecting "Mode" within the "Input A or B" sub-menu and pushing the
encoder activates "Input Monitoring" (indicated as "
P
" in the main
screen) An error message will be generated if no signal is detected.
Detection Time
The maximum time interval an interruption of the monitored pilot signal
or digital clock is accepted without creating an error message.
Notch on/off
A notch filter is available to remove the pilot signal from the program
signal. However, if activated, the Notch filter remains active even the
Input Monitoring is set to off (Mode off). The on/off status of the Notch
filter is indicated with "
n
" in the main screen as shown in the graphic
opposite - .
Frequency
Center frequency of the notch filter adjustable from 1 Hz to 20 kHz in
1 Hz steps.
Freq. Fine
Fine tuning of the center frequency ± 1 Hz, 1/100 Hz steps.
Quality
The Q of the filter is adjustable from 4 ... 42 in 1 detent steps. The
center frequency is fully attenuated (⇒ –∞ dB).
Detected? no (yes)
The signal level in dBu detected at the set pilot frequency is displayed
on the right hand side. "Detected?" is followed by the message ("yes" or
"no") depending on the threshold level (see "Threshold" below).
Threshold
Detection threshold for an external Pilot Signal of the set frequency,
adjustable in a range of –122 dBu to +21 dBu in 1 dB steps.
