MUX-8552A Overview
The RossGear MUX-8552A AES/EBU Embedder/Multiplexer is a broadcast quality modular product
used to write 20-bit AES audio streams (SMPTE 272M-A) to a 525 or 625 standard 270MB/s SDI
video signal. The MUX-8552A will embed two 48kHz AES-3id streams (1 group) and output two
copies of the embedded SDI signal. The RossGear MUX-8552A is for use in 75-ohm coaxial SMPTE
276M and AES-3id systems.
An SDI signal and 1 or 2 AES-3id signals are input through BNC connectors on the rear of the frame.
The MUX-8552A accepts both 525 and 625 format (SMPTE 259M-C) signals at 270Mb/s. Visual
indicators on the card edge provide indication of the presence of SDI and AES inputs. The MUX-
8552A provides automatic equalization for 300m of Belden 8281 cable. Two SDI outputs are
provided.
The MUX-8552A can embed one AES group into any one of the four AES groups available. The
group to be embedded is selected via a card edge jumper. Front panel LED’s provide information on
which groups are already present in the incoming SDI stream. The ability to overwrite an incoming
group is available through jumper selection. The MUX-8552A has been designed with the ability to
report a variety of AES signal errors including: no lock, biphase coding, parity, CRC check, sample
slip, and validity errors. These errors are indicated on a card edge (Error) LED. In addition, there is
SMPTE 269M fault reporting output to the backplane of the Ross digital rack frame.
The MUX-8552A is also available as the MUX-8552A-C version. The C version comes pre-
assembled from the factory with the AAM-8552A A/D daughter card, and the CON-8552 companion
rear connector module, which provides four balanced analog audio inputs instead of the AES digital
audio inputs.
The MUX-8552A fits into the Ross DFR-8110A or DFR-8104A digital frames. It provides system
builders the ability to easily distribute embedded digital audio in an SDI facility. The MUX-8552A is
part of a growing line of RossGear AES solutions, including distribution, conversion and monitoring.
The MUX-8552A also fits Leitch*6800 series frames.
Designed and manufactured to meet the highest quality broadcast industry standards, the RossGear
MUX-8552A is an ideal, cost effective solution for digital audio embedding.
MUX-8552A-C Overview
The RossGear MUX-8552A-C version, which comprises the MUX-8552A, the AAM-8552A
(daughter card), and the companion CON-8552 (connector adapter), is a broadcast quality modular
product used to allow four analog audio inputs to be embedded into a 525 or 625 SDI stream. The
AAM-8552A is a sub-module daughter card that plugs onto the top of the MUX-8552A RossGear
AES multiplexer card. The CON-8552 is a plug-on connector to the BNC module that connects to the
rear of the Ross DFR-8110A or DFR-8104A digital frame.
The AAM-8552A uses state of the art analog to digital converters that provide 24-bit resolution. A
coarse level adjustment (headroom) jumper (18dB or 24dB) and fine adjustment potentiometers (+/-
3dB, one for each channel) on the AAM-8552A, are provided to precisely match the converter to your
facility’s house reference audio level.
The AAM-8552A / CON-8552 is part of a growing line of RossGear AES solutions, including
distribution, conversion and monitoring. Designed and manufactured to meet the highest quality
broadcast industry standards, the RossGear MUX-8552A / AAM-8552A / CON-8552 is an ideal, cost
effective solution for digital and analog audio multiplexing requirements in your facility.

Board Installation
Note the following points when installing the configured MUX-8552A card in a RossGear 8000 or
8000A series digital distribution frame:
Notice
The MUX-8552A-C card configuration must be installed in a
Ross Video 8000A series digital distribution frame with a
cooling module option installed.
• Refer to the User Manual of the RossGear 8000 or 8000A series frame, to ensure
that the frame is properly installed according to instructions. If this module is to be
installed in any compatible frame other than a Ross Video product, refer to the
manual that came with your frame, for specific instructions.
• Please note that heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing components
should be arranged to avoid areas of excess heat build-up, particularly in frames
using convection cooling.
• After selecting the desired frame installation slot, hold the MUX-8552A card by the
edges and carefully align the card edges with the slots in the frame. Then fully insert
the card into the frame until the rear connection plug is properly seated.
BNC Labels
Affix the supplied BNC label, as per the included instructions, to the BNC area on the rear of the rack
frame.
MUX-8552A Cable Connections
The following section provides instructions for cable connections when mounting the MUX-8552A in
a RossGear 8000 or 8000A series Digital Distribution Frame. If this card is installed in a compatible
distribution frame other than a Ross frame, note that the cable designations may vary.
Use the diagram below to attach the required BNC cables such as the SDI input and output, AES input
and output streams.

Analog Cables
On the CON-8552 adapter, there are removable connectors for sockets Analog Audio IN- 1A, 1B, 2A,
and 2B. Each connector has sockets for the positive, negative, and grounded wires of a balanced
analog audio cable.
Wire the external cables to the terminal block connectors as outlined in the diagram and procedure
below.
Figure 4. Connector Wiring for CON-8552 Input Sockets
Use the following procedure to wire the external cables to the terminal block connectors:
1. Insert an analog audio wire to the designated polarity slot on the connector.
2. Use a tweaker screwdriver to tighten the corresponding screw on the underside of
the connector.
3. Repeat steps 1 and 2 for each wire on each connector.
Once the cables have been wired to the connectors, install the connectors to the sockets on the CON-
8552 adapter so that the slotted tongue fits in the grooves on the adapter socket.

MUX-8552A-C Gain Adjustment
If necessary, use a tweaker screwdriver to adjust the fine analog audio input levels for each channel on
the AAM-8552A. See Figure 6 for potentiometer locations. The potentiometer assignments are:
• RV4 for AES1A
• RV3 for AES1B
• RV2 for AES2A
• RV1 for AES2B
These potentiometers provide 9dB range of adjustment on the –18dBFS jumper setting and a 6dB
range of adjustment on the –24dBFS jumper setting. Using these adjustments, the total headroom is
adjustable over the –15 to –27dBFS range.
Note All fine levels are factory set for unity gain and should not need
adjusting.
An extender card is required (EXT-8100) to adjust
potentiometer settings. Refer to the section, “Optional
Equipment” in this manual, for details.
