and set the Silence Threshold to the level be-
low which the 5700i will interpret the input as being silent.
This setting is with respect to the current analog reference level and digi-
tal reference level.
B) Press

control. Set it to the amount of
time that the input must be below the Silence Threshold before the 5700i au-
tomatically switches to the analog input.
C) Press

if you
wish the 5700i to switch automatically from the digital to analog input when
silence is detected. Set the control to

to defeat automatic switching.
D) Press Next as necessary to see the DI A

4. Program Tally Outputs.
[Skip this step if you do not wish to use the tally outputs.]
See step 6 on page 2-4 for wiring instructions.
You can program the two tally outputs to indicate a number of different opera-
tional and fault conditions.

B) Program tally output #1.
To program a given tally output, press and hold the soft button associ-
ated with the output you are programming. As you turn the control
knob, the functions listed below will appear in the highlighted field.
•
Input: Analog : Indicates that the 5700i is processing audio from its analog
input.
•
Input: Digital : Indicates that the 5700i is processing audio from its AES3
digital input.
•
Analog Input Silent : Indicates that the level at either or both analog in-
put channels is below the threshold set in step 3 on page 2-24.
•
AES Input Silent : Indicates that the level at either or both digital input
channels is below the threshold set in step 3 on page 2-24.
•
AES Input Error : Indicates that the 5700i’s AES input receiver chip has de-
tected a problem with the data being received such that the data is unus-
able. When the chip detects such an error, it automatically switches the in-
put to
A
NALOG
.
•
Sync Reference Input Error : Indicates that the 5700i has detected a prob-
lem with the signal being received at the sync reference input such that the
