(2) Notify the R.L. DRAKE LLC or the nearest authorized service facility, as soon as
possible after discovery of a possible defect, of:
(a) the model and serial number,
(b) the identity of the seller and the approximate date of purchase; and
(c) A detailed description of the problem, including details on the electrical connection
to associated equipment and the list of such equipment.

Warranty Statement

Introduction
The Drake® HDE24 high-definition en-
coder generates an MPEG2 or
MPEG4 H.264 video stream, with
Dolby® AC-3 or MPEG1 layer 2 audio.
This module is designed to be in-
stalled into the Drake EH24- or
MEQ1000-style chassis, which
provide the control and output inter-
faces to the unit. The encoder ac-
cepts HDMI™ and component inputs,
and can inject closed-captioning data
from a synchronized composite video
source (typically provided by the same
decoder that produces the HD video
stream).
Installation
This unit installs into the chassis in the
same fashion as the SDE24 encoder;
for chassis insertion instructions, see
the manual for your particular chassis.
DO NOT INSERT THIS ENCODER
WITH POWER APPLIED TO THE
CHASSIS - RESULTING DAMAGE
WILL NOT BE COVERED BY THE
LIMITED WARRANTY. Cable the in-
puts appropriately (see the Rear
Panel Connections section for details).
Upgrading Firmware
The HDE24's firmware may be
upgraded in the field, using a
removable USB flash drive. Once you
have obtained the latest firmware
version file, copy the file onto a
removable flash drive. The file must
not be placed in any sub-folder of the
drive. Power down the chassis, insert
the flash drive into the Service port on
the unit, and apply power to the
chassis. The HDE24 will
automatically upgrade and then
reboot. Once the unit is functioning
normally again (encoded audio and
video is being generated), remove the
flash drive from the unit.
Operation
Power on the chassis, and select the
newly-inserted HDE24 unit via the
LEFT and RIGHT buttons on the front
panel. The following configuration set-
tings are available for the HDE24 (de-
faults listed in bold italics):
Video Source: Component, HDMI,
Composite - sets the input video
format
Resolution: Scan, 1080i, 720p, 480p,
480i - auto-scan input resolution, or
force a particular video mode. Not
available for composite (composite
is always 480i)
Format: MPEG2, MPEG4 H.264 -
sets the video compression method
used
MPEG4 Profile: Default, Simple, Ad-
vanced Simple - sets the MPEG4
video profile used (only available
when format is MPEG4 H.264)
MPEG4 Level: 0, 1, 2, 3, 4, 5 - sets
the MPEG4 encoding level (only
available when format is MPEG4
H.264)
Bitrate: Range varies by resolution -
sets the bandwidth used by the
video encoder (15.0 Mbps)
Brightness: Sets the video
brightness - larger values increase
brightness (128)
Contrast: Sets the video contrast -
larger values increase contrast
(128)
Saturation: Sets the video contrast -
larger values increase saturation
(128)
Hue: Adjusts the video color hue -
behavior varies by input mode (128
for Composite, 0 for other inputs)
Audio Source: Analog, HDMI -
select audio input source (only
available when video input is HDMI)
Audio Encode: AC-3, MP2 - changes
audio encode format between
Dolby AC-3 and MPEG1 Layer 2.
Audio Gain: varies audio level +/-
15dB (0, only avaliable when audio
input is Analog)
Introduction, Setup, and Operation 1

Rear Panel Connections
1: Component video input. Y input is used for
Composite video input as well.
2: Analog audio input.
3: Service port. Used during firmware updates of unit.
4: HDMI input. Supports embedded PCM audio.
Does not support HDCP/Copy protection.
5: Closed captioning data input. Used during high-
definition encodes to insert closed-caption data
from a composite video source.

Notes
1. If the front panel display shows
INVALID VIDEO, the incoming
video is not correct for the input
type and resolution settings. If the
front panel display shows INVALID
AUDIO, the HDMI embedded audio
source is not available or not PCM
(uncompressed).
2. This encoder will only support the
specific video resolutions outlined
in the Specifications table.
3. This encoder does not support
HDMI copy protection (HDCP). All
HDMI sources must be un-encryp-
ted.
4. Composite video is supported -
use the Component Y (green-
colored) input connector.
5. Closed-captioning data is
automatically extracted when the
encoder is in Composite mode. All
other modes require a captioned
composite video source input to
the Caption connector.
6. Firmware updates may be re-
quired for MEQ1000 or EH24
chassis. MEQ1000s must be up-
dated to v1.4 or later. EH24s must
be updated to v2.3 or later.
