6.0 E-4 System Setup
The following chart shows how Source Leveling operates. For
sources whose average input signal level is less than –20 dBV,
Source Leveling will add 20 dB of gain. For sources whose aver-
age signal level is between –20 and 0 dBV, Source Leveling will
add the necessary gain so that the average output of the Source
Leveling function is +11 dBV. Sources whose average level is
greater than 0 dBV will have gain reduction applied so that they
maintain an average of +11 dBV at the Source Leveling output.
Input signals from –20 to 0 dBV fall within the ideal operating
range for the Source Leveling function. This is reflected in the
color scale used for the input gain signal level meter. If your input
signal level is within the green area of –20 to 0 dBV, Source Level-
ing will effectively manage the input source level.
6.3.4 Source assign
In the Source Assign control, you can choose which system
sources will be available in each zone. The Source Assign control
panel lists all system sources on the left and zone sources on the
right. Sources are assigned by moving them from the System
Sources list to the ZONE Sources list.
Factory default settings
Programmer’s Notes:
1. Because the E-4 hardware is a router, at least one
source must always be assigned to a zone.
2. If you try to remove all sources from a zone, the last
active source will always remain assigned to the zone.
3. This function is disabled for zones in which Auto Vol-
ume is enabled (On). If you turn Auto Volume off and
change source assignments, you will need to recali-
brate Auto Volume.
4. Any source assigned to ZONE 4 will also be sent to
the AUX OUT/CONTROL output.
To assign a source to a zone
1.
Select a source in the System Sources list.
2.
Click the right arrow ( ) button to move the highlighted
selection to the ZONE Sources list.
