MUTE A/B
Note:
As the MUTE A/B switches isolate the D6 digital controller from the
power amplifiers the MUTE A/B switches do not affect the input
connectors of the D6 and therefore "Input Monitoring" remains working
(also refer to the D6 Hardware manual in section "Controls and
indicators – MUTE A/B").

Selecting "Mode" and pressing the encoder allows the setting of the
following functions:
Analog Pilot
monitor incoming pilot signal at the analog inputs
Digital Pilot

Input A / Input B
Selecting either "Input A" or "Input B" and pressing the encoder allows
the following settings for each channel independently.
Mode
Selecting "Mode" in the "Input A or B" submenu and pressing 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 generating 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 if the
Input Monitoring is set to off (Mode off) indicated as "
n
" in the Main
screen.

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 - 94dBu
Threshold - 42dBu
Detected? yes - 42dBu
Threshold - 42dBu
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.
