This package contains:
One HDD ATSC/QAM Rack Demodulator
One HDD Installation Manual
2. PRODUCT DESCRIPTION
The HDD is an ATSC/QAM professional grade rack demodulator designed for cost effective
digital-to-analog conversion of an unencrypted 8VSB (Off-Air SD/HD TV signal) or QAM
unencrypted (digital CATV) RF signal to baseband NTSC video and left and right stereo
audio outputs. All of the 18 ATSC video formats including HD format can be received by the
HDD and converted to display on non-digital TV sets over analog channels with the use of a
modulator

5. INSTALLATION AND HARDWARE CONNECTIONS
A. Un-box the HDD and ensure that all accessories (including screws) are removed from the
box before discarding the packing material.
B. Mount the HDD into a standard 19” EIA rack keeping in mind to use adequate spacing for
proper ventilation. Follow the instructions below for connections.
C. Connect a 75-ohm coaxial cable with proper connectors from the HDD Antenna Input Port
to the Off-Air antenna or cable source.
D. For mono audio output connect an audio cable from the HDD “Audio LEFT” (White) output
port to the modulator’s audio input.
For output to a stereo modulator connect audio cables
from the HDD’s “Audio LEFT” (White) and “Audio RIGHT” (RED) Output ports to the
modulators Left and Right audio ports.
E. Connect a video cable from “Video Output” of the HDD to the Video Input of the modulator,
use of F to RCA adaptors may be necessary to make the connection.
G The HDD is designed to be powered by AC 110V/60Hz power. Using the wrong power
source and/or power voltage can damage the HDD. The use of a surge protector and a UPS
is highly recommended. Product warranty does not cover surge or spike damages.
H. Connect the HDD to the AC power source.
Note: 1 HDD is required for each channel to be converted and demodulated. Also, 1
modulator is required for each channel to be re-modulated.
6. OPERATIONS AND SETTINGS
A. Press the “Air /Cable” button to select Off-Air (8VSB), Cable (QAM), Cable inverted (QAM
inverted) or Cable normal (QAM normal) for the input signal type.
B. Press the HDD SCAN button. The HDD will initiate a channel scan for available
signals/channels in the given area. The word “SEARCH” will flash on the HDD display. The
scan process can take several minutes. You should know what channels are available, so
you can determine which of those signals needs to be converted and demodulated.
C. When the channel scan is complete, the first found channel number will be shown on the
HDD Display. The HDD may find multiple channels, use the CH+ and CH- Buttons to scroll
through the available channels until you find the one to be converted and demodulated. The
HDD LOCK LED will light up indicating a channel has been found and selected.
D. By pressing the ZOOM button the user can select up to seven screen types: 4:3/Center,
4:3/Full, 4:3/Letter, 4:3/Zoom, 16:9/Center, 16:9/Letter, 16:9/Zoom. 4:3 is for standard TV
display, and 16:9 is for widescreen display. The Zoom feature allows the selected channel
image to be displayed as FULL (full screen display), LETTER (letter box with smaller image
surrounded by a black border), and Center.

E. The HDD provides a Secondary Audio Programming selection feature. To select English
press the AUDIO button until the display reads LANG1. To select SAP press the AUDIO
button until the display reads LANG2. The available language depends on what the stream
contains. Not every stream has multi-language selections. Some have 2 or more language
selections, but most streams have just 1 language.
Note: Some broadcasters do not default the SAP audio back to English if the program does
not have SAP. When a program does not have SAP, and the HDD is set to LANG2, there
may be no audio outputted from the HDD. Simply select LANG1 if this problem exists.
F. To adjust the volume of the HDD, press and hold the AUDIO button, then press the CH+ or
CH- button to increase or decrease the volume .The HDD has a factory set volume of 75%.
(Sample 12)
G. To view the selected channels signal strength, press and hold the ZOOM button, then
press the CH+ button. (Sample 13)
H. To view the signal quality of the selected channel, press and hold the ZOOM button, then
press the CH- button. (Sample 14)
I. To reset to the unit to the factory default settings press and hold the SCAN button for 10
seconds.
