1 Product Overview
Down) select which delay (Diversity Delay or the
optional Profanity Delay) is being monitored and
allow basic Ramp Up/Down control. The 10-Char-
acter displays show the status of the delay. The
Ramp Up/Down LEDs indicate whether the de-
lays are at zero, are ramping, or are complete.
More extensive control over the delays is done
through the ECC app. A hardware studio remote
panel can also be used to control such Profanity
Delay features as Dump, Rebuild, and Ramp to
Zero, and Diversity Delay control of Ballpark
mode, which ramps the Diversity Delay out so that
the analog broadcast of a live event (like a sport-
ing event) can be done with minimal delay.
The front panel Monitor Select button allows
any audio input or output to be monitored on the
front panel level display, the front panel headphone
jack, and the rear panel
Ref Mon Out connection,
which can feed a pair of digital monitor speakers.
A Fault LED on the front panel blinks if a GPS
lock or audio fault occurs. Pressing the Fault but-
ton brings up a Fault display overriding the nor-
mal monitor level display.
There are two AES digital audio inputs on the
HDE-200 (
Main Delay In and MPS Audio In ).
The
Main Delay In put is typically used for the
audio going to the analog carrier, although it can
also be the set as the source for the HD Radio
main channel when both signals use common air
chain processing. When the HD Radio main chan-
nel and analog broadcast use different signal pro-
cessing, then the HD Radio main channel audio
is connected to the Main Program Signal input
(
MPS Audio In ).
Main Delay Out , which feeds the analog trans-
mission chain, goes through an adjustable Diver-
sity Delay to compensate for the HD Radio signal
processing time. This is so an HD Radio receiver
will smoothly blend between the analog carrier
and digital main channel without any time-shift-
ing artifacts. The ECC app is used to select which
input signal feeds this output and to set the length
of the Diversity Delay to keep the analog and digi-
tal broadcast audio outputs aligned in time.
A digital monitor output (
Ref Mon Out ) can feed
a local digital audio monitor. Its source is set by
the front panel Monitor Select button, between
MPS in, MPS out, Main Delay In, and Main De-
lay out.
The 320 kbps E2X transport stream is output
on the three Ethernet connections built into the
HDE-200. These allow an HD Radio Exciter or
Digital STL, plus an HD Radio
Importer and an
admin computer, to directly connect to the HDE-
200 so a separate LAN switch is not required,
although the HDE-200 can interconnect though
any standard LAN switch, if required.
1.1.2 HDE-200 UPGRADES
Three upgrade kits are available: Profanity De-
lay (HARHDE200-PROFAN); Arbitron PPM En-
coder Interface (HARHDE200-PPM); and a com-
bined Profanity/PPM Encoder Interface
(HARHDE200-PROF/PPM).
The Profanity Delay kits add a second delay
function to the HDE-200—with remote studio
logic control via a parallel logic I/O port or via
on-screen commands, so that a separate profanity
delay controller is not required. It has variable
ramp times and allows delays of up to 35 seconds
to be set using the HDE-200 ECC app.
The Arbitron PPM Encoder Interface allows two
PPM Encoders to be used to separately add in
the Personal People Meter encoding to the main
HD Radio and analog carrier audio streams. These
are both sent post Diversity Delay so that ramp-
ing in/out does not affect the PPM Encoding. The
PPM Encoders connect to the HDE-200 using a
standard XLR interface cable (supplied with the
upgrade kit) that plugs into the Post Delay Loop
I-O connector.
