INSTALLATION ORBAN MODEL 6300
“digital input” silence detector is used for automatic input switching.
(See step 17 below.)
Silence sense will be activated if either channel falls silent, thus also pro-
tecting against “loss-of-one-stereo-channel” faults.
If silence is detected at the analog input as well as the digital input (as in
the case of a studio operational fault), automatic switching will not oc-
cur.
When an active signal is restored to the digital input, the 6300 will
automatically switch back to that input.
This feature is unavailable in the 6300's audio processing mode.

SILENCE THRESHOLD
and set the Silence Threshold
to the level below which the 6300 will interpret the input as being silent.
This setting is with respect to the current analog reference level and digi-
tal reference level.

control. Set it to the amount
of time that the input must be below the Silence Threshold before the 6300
automatically switches to the analog input.

if you
wish the 6300 to switch automatically from the digital to analog input when
silence is detected. Set the control to

to defeat automatic switching.
17. 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 6300 is processing audio from its analog
input.

Input: Digital : Indicates that the 6300 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 16 on page 2-28.

AES Input Silent : Indicates that the level at either or both digital input
channels is below the threshold set in step 16 on page 2-28.
