Chapter 1: Introduction
Overview
The HD10AM is a dual rate 8 channel AES audio Embedder/Disembedder. The
Disembedder is always functional, outputting group 1 and 2—or 3 and 4 (user
selectable) when present on the input SDI. This is independent of the embedding
process. The Embedder is user selectable, on a channel pair basis, to either “pass” SDI
input audio or embed input AES audio from the breakout cable. The ability to pass
incoming ancillary data makes it possible to embed up to 16 channels of audio by
cascading two units: the first embedding to groups 1/2, and the second embedding to
groups 3/4—or vice versa. It also means that any ancillary data packets in compliance
with SMPTE 291M will be passed through as-is.
With the SRC DIP switch setting ON, AES inputs are sample rate converted to a 48KHz rate
synchronous to the video input.
The HD10AM automatically detects and configures to the input video standard. The Lock
LED glows red for HD and green for SD formats.
With the SRC DIP switch setting OFF, data packets are passed from the AES inputs to
embedded ancillary packets un-altered. This is done according to SMPTE 337M. 48KHz
synchronous ancillary packets are disembedded and passed unaltered to the AES
outputs regardless of the position of the SRC DIP switch.
All AES3-2003 defined channel status bits are passed through unaltered in both the
embed and dis-embed directions—except for the sample rate field, which is always set
to 48KHz. The channel status CRC is re-calculated and inserted into the bitstream. This
ability, along with a very small audio embed/disembed latency, ensures 100 percent
compatibility with Dolby® bitstreams.

HD10AM I/O Connections
User Controls
The HD10AM has an 8-switch DIP accessible through a cut-out in the bottom of the unit.
The DIP switches are used to configure the unit’s audio embedding and disembedding,
and control ancillary data.
Factory default switch settings are all in the leftmost position.
The exact functions of the DIP switches are described in “Operation” on page 9.

Installation
Typically, HD10AM installation consists of the following:
1. Disconnect +5VDC from the converter.
2. Set the DIP switches for the desired equipment configuration.
3. Connect video equipment to the converter BNCs.
4. Connect the breakout audio cable to the converter.
5. Connect audio equipment to the breakout cable (see Figure 1 for pinouts).
6. Apply power to the converter.
