A Word of Thanks
Congratulations on choosing the openGear EMD-218 HD/SD Audio Embedder/De-embedder. The
EMD-218 is part of a full line of modular conversion gear for broadcast TV environments. The Sierra
Video Systems openGear line includes video decoders and encoders, audio embedders and deembedders, distribution amplifiers, format converters, and much more. Sierra openGear modular
conversion gear will meet your signal conversion needs now and well into the future.
Should you have questions pertaining to the installation or operation of your EMD-218, please contact
us at the numbers listed on the back cover of this manual. We are happy to help with any questions
regarding this or any other openGear card.
Overview
The EMD-218 is a high quality audio embedder/de-embedder capable of embedding audio signals into
HD or SD SDI signals, and de-embedding audio data from those signals. It also gives as outputs, two
re-clocked copies of the input.
The EMD-218 can best be thought of as an audio router on a card. On the input side of the router are
the up to 16 channels of embedded AES in the input video, the up to16 channels (8 pairs) of discrete
AES input, up to 8 channels of differential analog audio input, a nd up to 10 channels (8 signals plus
mixdown) of decoded Dolby signals (with Dolby Decoder option). On the output side are the up to 16
channels of embedded AES audio, and the up to 16 channels (8 pairs) of discrete AES output. The
router acts as a full audio cross point: each of the 32 output channels (16 embedded AES, 16 discrete
AES) can receive signal from any one of the 52 (16 embedded AES, 16 discrete AES, 8 Analog, 10
Dolby decoded) input channels. Each output also allows gain adjustment and optional polarity
inversion.

Audio rates are always 48kHz nominally but discrete AES inputs pass through sample rate converters
to align them with the output timing. Output AES is always precisely locked in time with the output
video. Analog audio is differential input and sampled at 48 kHz with 0 dbFS digital equivalent to +24
dBu analog. Dolby decoding is available from embedded audio or external AES, with the purchase of
the Dolby decoding option.
The product also provides full color processing control of the output video, with separate controls for
Gain, Lift, Saturation and Color Phase.
All card configuration is done with a simple front panel menu. There is a four character text display to
view and control parameters, and a toggle switch and t wo buttons to navigate the menu.
The input and outputs of the EMD-218 are the following:
Input:
One dual-rate HD/SD-SDI video input
4 dedicated AES input connections (AES input 5-6)
8 differential analog audio inputs
Switchable Input/Outputs:
4 AES connections, switchable between input and output (AES input/output 1-4)
Outputs:
Two dual-rate HD/SD-SDI video outputs
Two dual-rate HD/SD-SDI re-clocked copies of input
8 dedicated AES output connections. (AES output 1-8)
Software Version
This manual is written for software release number 2.0.
To view the current software release number of your EMD-218 check the informatio n s ubmenu on
the front edge controls or the card info menu in Dashboard.
To upgrade your EMD-218 software, go to the download page at www.sierravideo.com to
download the latest release, and upload the file through Dashboard™ (see Dashboard™ user
manual, 3-5).
