Overview
1.0 AVM Hardware Overview
The AVM Audio/Video matrix contains two major components. The audio and the video switch are con-
trolled by multiple CPUs under the command of the application CPU as shown below.
1) The audio matrix is a fully controllable crosspoint matrix. At every crosspoint the user can independently
specify variables such as target value, ramp time, slew rate etc. AVM provides the following sizes of audio
matrices: 8 X 8, 16 X 8, 24 X 8, 32 X 8, 8 X 16, 16 X 16.
2) The video section is a completely transparent video switch capable of switching a wide range of popular
formats. With Intelixs supplied Windows® based setup software video sources are grouped with their
associated audio inputs, and the group can be rerouted with a single command. The video switch is available
in a wide range of standard sizes from 8 X 8 composite to 8 X 8 RGBHV.
The tight coupling of audio and video in the same chassis allows the very flexible and convenient grouping
and manipulation of complex AV sources. For instance a five signal (RGBHV) video source and its associ-
ated stereo audio can be grouped and manipulated as a single object.
Control of the AVM is accomplished either with the supplied Intelix software or via an external RS232
controller. Common RS232 commands and protocol are covered in later sections of this manual.
Fig. 1. This exploded
drawing shows the audio
(lower) and video (upper)
sections of a typical AVM.
Both sections are contained
in a single chassis.

Overview
1.1 Audio Section
The Intelix audio matrix mixer is a device which can route and mix audio signals from multiple sources to
multiple destinations. The matrix mixer is designed so that audio inputs can be independently mixed to any or
all outputs simultaneously. As shown below there is a VCA under software control at every I/O crosspoint.
The audio matrix can be controlled either by the supplied Windows® based software or by RS232 com-
mands.

Overview
1.2 Video Switch Architecture
The drawing below shows the architecture of an 8 X 8 section of a video switch. All crosspoints are switch-
able, but no more than one input can be switched to a given output at a time; i.e. only one closed switch per
column. An input can be sent to any number of outputs; i.e. any number of closed switches per row.
All video inputs are assigned to a video group. All video switching is accomplished by issuing a route video
group message. Even a single wire video input; e.g. composite is assigned to a video group. A video input
cannot be assigned to more than one group. This means that not all crosspoint switches are independently
controllable, since if an input is part of a group it cannot be switched to an output independently of its group.
This drawing (below) shows how 16 X 16 video switch cards can be combined to form larger video
switches. The smallest AVM product has only section #1. Other AVM models add sections #2 and/or #3 to
form larger switches (#3 cannot be added without adding #2). Note that this sparse matrix cannot be filled
in. A video group (such as an RGB input) can contain signals that span sections, but a single signal
cannot cross sections; e.g. input 2 cannot be routed to output 18 even if section #2 is present.
