Sage Digital ENDEC Quick Start Rev 2.0
Pass Through: No
Relay always on: No
Clock: External or internal
3) Alert generation only. In this mode, a downstream external switcher places the ENDEC's digital
audio into the station's digital signal. Switching occurs as a result of the ENDEC closing one of the
four contact closures (the Push To Talk function). The ENDEC will generate digital data only when
an alert is in progress. An input signal to the ENDEC is not needed, but if the downstream switch
wants to see the ENDEC clock synchronized with house clock, then an input audio stream must be
provided to the ENDEC’s Digital In.
Settings:
Enable Digital Audio: Yes
Pass Through: No
Relay always on: No
Clock: External or internal
4) Alert generation with idle. This mode is the same as "Alert generation only" except that the ENDEC
will always output a digital signal, sending silence when an alert is not in progress. This mode is
used if the downstream switcher wants to see signal at all times. An input signal to the ENDEC is
not needed, but if the downstream switch wants to see the ENDEC clock synchronized with house
clock, an input signal must be provided.
Settings:
Enable Digital Audio: Yes
Pass Through: No
Relay always on: Yes
Clock: External or internal
Each digital control setting is described in detail below.
12.2.2 Digital Audio Clock
The ENDEC can derive digital audio clock from the input audio stream, or it can provide its own clock.
Important! Even if you set the ENDEC for external clock, you must still set the ENDEC Clock Rate
parameter. The rate setting also controls the conversion of the various audio sources, both analog (from the
monitor inputs) and digital (from CAP messages), to the proper digital speed. Failure to set the rate
correctly will result in either a playback that is fast and high pitched, or that sounds like HAL on the last
verse of Bicycle Built for Two.
12.2.3 Digital Audio Levels
The MENU.DIGITAL LEVELS menu or the ENDECSetD Digital Audio tab can be used to set the levels of
the various tones, similar to the setting of the analog audio levels in the
MENU.LEVELS or Levels tab.
12.2.4 Digital Audio Menu Items
The following items are available on the ENDECSetD Digital Audio tab, or on the front panel
MENU.DIGITAL AUDIO menu.
12.2.4.1 Enable Digital Audio
If enabled, the ENDEC will send alerts to the digital output and will light the front panel Lock LED if a
digital input is present.
