“Word clock” – Configuring the word clock
Via the “word clock” menu item, you can ...
• switch between the following word clock signals:
– internally generated word clock signal
– external word clock signal
– word clock signal of a built-in MAN card
• adjust the sampling rate (44.1 kHz, 48.0 kHz, 88.2 kHz or 96.0 kHz)
with which – with an internally generated word clock signal – analog
signals are digitalized and output at the XLR-3 sockets A.
“Cable attn” – Displaying the cable attenuation and automatically
compensating for it
The EM 9046 receiver measures the cable attenuation between the
antenna boosters and the antenna inputs E and F and automatically
compensates for it:
• during the boot routine
• if both antenna boosters are connected or replaced
If only one antenna booster is connected or replaced, the cable attenu-
ation will not be measured.
To manually initiate the compensation of the cable attenuation:
왘 In “sys” operating mode, turn the jog dial until “cable attn” appears.
왘 Press the jog dial.
“Press SAVE to calibrate” is displayed on the display panel.
왘 Pres the button.
During the measurement, the channel status display A displays “Cali-
brating” for each channel. The receiver is muted for approx. 10 seconds.
Then the result of the measurement is displayed as follows:
