he HDE-200 has limited front panel con-
trols, which are for engineering use only. Board op-
erators and other users interface with the HDE-200
through using the Exporter Control Center (ECC
app), a software application running on Windows
TM
XP, Vista, or Windows 7 Pro computers networked
with one or more HDE-200 Exporters, or through
a hardware button control panel.
4.1 HDE-200 Controls
The front panel controls on the HDE-200,
shown below, allow engineers to monitor various
audio inputs and outputs both visually, through a
front panel level display, and aurally, through a
front panel headphone jack or the rear panel AES
monitor output. Only three buttons—Monitor Se-
Using the HDE-200
lect, Headphone Volume up and Headphone Vol-
ume Down, are needed to quickly select, view, and
listen to any input or output.
A dual row dot matrix display shows the name
of the Monitor Source Signal in its top row while
the stereo signal level is shown in the lower row.
This display can alternately show alarm condi-
tions; delay status for the Diversity and optional
Profanity Delay; and the headphone output level.
4.1.1 SELECTING THE MONITOR SOURCE
Press the
Monitor Select button to sequentially
step through the four monitor sources:
Main In
is
the analog transmission’s input signal;
MPS In
is
the digital transmission’s input signal;
Main Out
is the analog transmission’s output signal from
the HDE-200; and
MPS Out
is the internal-only
audio signal feeding the iBiquity DSP board. Note
that
MPS In
will not be available if the HDE-200
is set to use a common input (Main In) as the
source for both the analog and digital transmis-
sion chain signals. In addition, the output of the
iBiquity DSP board cannot be monitored by the
HDE-200 since it is the E2X serial data stream
