The HDE-200 can be mounted in a studio,
terminal room, or transmitter facility. It requires one
rack unit (1RU) of space. No special venting require-
ments are required and low power equipment can
be mounted directly above and below the unit.
2.1 Installation Overview
All HDE-200 signal and power connections are
made on the rear panel. There are no internal
adjustments on the HDE-200, but there are op-
tional upgrade kits that require removing the top
cover for installation. We recommend installing any
upgrade kit (Profanity Delay and/or Arbitron
PPM Encoder Interface) before the HDE-200 is
rack mounted. Upgrade kit installation instruc-
tions are presented on page 2-3.
The HDE-200 draws about 30 watts from a
100-240 VAC, 50/60 Hz outlet. An IEC power
cord, terminating in a Type B plug (for the USA,
Canada and Japan) is included with the HDE-200.
The HDE-200 is designed to be rack mounted
using four rack screws.
2.1.1 AUDIO CONNECTIONS
There are four AES-3 balanced digital audio
connections using XLR-type connectors. All con-
form to standard AES-3 (AES/EBU) digital wir-
ing practices (3 volt signals, 110 ohm, balanced
lines) and levels (-20 dBFS corresponds to 0 VU
on the on-screen metering). For best results use
110 ohm balanced wiring suitable for digital au-
dio signals on these four connections.
Note that unbalanced 75 ohm S/PDIF digital
audio signals can be connected to the AES inputs.
See page 2-6 for connection details.
The HDE-200 has two audio inputs: the Main
Program Service input (
MPS Audio In ), which is
the audio for the HD Radio main channel; and
the
Main Delay In , which is the audio input for
the analog broadcast carrier. If the HD Radio main
channel and analog carrier will use the same sig-
nal, then connect to the
Main Delay In connector.
Which inputs are active is set using the Exporter
Control Center program (ECC app).
The
Main Delay Output feeds the analog trans-
mission chain. It is time delayed, by the Diversity
Delay setting, so that HD Radio tuners will
seamlessly switch between the analog carrier and
the HD Radio main channel. The Diversity Delay
will be roughly eight seconds when compared to
