Introduction

Introduction, cont’d

Introduction

The Extron MAV Series switchers are broadcast quality matrix switchers that
distribute any video and/or audio input to any combination of outputs. The MAV
switchers can route multiple input/output configurations simultaneously. There
are four matrix sizes available, each with unique features or optional capabilities:

• MAV 84 RCA (eight inputs by four outputs)

• MAV 128 RCA (twelve inputs by eight outputs)

• MAV 168 (sixteen inputs by eight outputs)

• MAV 1616 (sixteen inputs by sixteen outputs)
The MAV 84 and MAV 128 input and output audio on RCA connectors.

Audio models in the MAV 168 and MAV 1616 series input and output audio on

3.5 mm, 5-pole captive screw terminals. The MAV 168 and MAV 1616 are available
in models that can switch three video planes (component video), two video planes
(S-video), or one video plane (composite) video, each with or without an audio
plane. An audio-only matrix switcher is also available in the MAV 168 and
MAV 1616 series.

MAV component video switchers can also route RGsB and RsGsBs video signals.
Switchers configured for component video can also route multiple composite video
planes or S-video and composite video. If used in this way, the various planes
cannot be broken away; all inputs must be routed to the same outputs.

MAV S-video switchers can also be used to switch two planes of composite video.
If used in this way, the two planes cannot be broken away; both inputs must be
routed to the same outputs.

For the models with audio, audio switching can either be linked with the video
(audio follow) or be independent of the video (audio breakaway). Adjustable
audio gain and attenuation compensates for level differences between audio
inputs.

The MAV Series switchers are single-box solutions to simple 150 MHz (-3dB)
routing applications (figure 1-1, figure 1-2, figure 1-3, and figure 1-4). Each input
and output is individually isolated and buffered, and any inputs can be switched to
any one or all outputs with virtually no crosstalk or signal noise between channels.

The MAV component video switchers are housed in a 4U high enclosure. MAV
S-video switchers are in a 3U enclosure. MAV composite and audio-only switchers
are in a 2U enclosure. The appropriate rack mount kit is included with each
switcher. Each model has an internal 100VAC to 240VAC, 50/60 Hz, 15 watts
(MAV 128 RCA) or 20 watts (MAV 168/1616 series), auto-switchable power supply
that provides worldwide power compatibility.

program provides a versatile range of operational options with its graphical
interface and drag-and-drop/point-and-click operation. The Windows-based
control program also has an emulation mode that lets you create a switcher
configuration file at the home office and then download it for use by the
switcher on site.

• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s

SIS for easy programming and operation.

Labeling — Extron’s label software ships with every Extron matrix switcher. You

can create labels to place alongside the front panel I/O buttons, with names,
alphanumeric characters, or color bitmaps for easy and intuitive input and
output selection. Alternatively, labels can be made with any Brother P-Touch
or comparable labeler.

Global memory presets — 12 (MAV 128) or 16 (MAV 168 and MAV 1616) global

memory presets are a time-saving feature that lets you set up and store
input/output configurations in advance and then recall those configurations
when needed with a few simple steps.

Rack mount — Rack mountable in any conventional 19” wide rack.
Power supply — Includes an internal 100VAC to 240VAC, 50/60 Hz, 15 watts

(MAV 128 RCA) or 20 watts (MAV 168/1616 Series), auto-switchable power
supply, which provides worldwide power compatibility.

Switching — Provides individually buffered, independent matrix switched outputs.
External sync input and output connectors — Allow the switcher to use an

external signal to synchronize switching during the vertical interval.

Installation Overview

To install a MAV Series switcher, do the following:

If desired, mount the switcher in a rack (see Mounting the switcher below).

1

Turn off power to the input and output devices, and unplug the power cables

2

from them.

Attach the input and output devices to the switcher (see Cabling and Rear

3

Panel Views below).

If desired, attach an external sync timing device to the external sync

4

connectors (see External sync connection on page 2-6).

If desired, attach an MCP 1000 remote control panel master unit to the

5

switcher’s RS-232/422 connector. You can also attach an MKP 1000 remote
keypad or MCP 1000 slave unit to the MCP 1000 master unit. Refer to the
MCP 1000 Remote Control Panel User’s Manual and the MKP 1000 User’s Manual
for details.

Plug the switcher and, if appropriate, the input devices and output devices

6

into a grounded AC source.

Turn on the input and output devices.

7

The image from each input device should appear on the output devices, and

8

you should be able to switch from one input device to another. If this does
not happen, double check steps 3 through 5 and make adjustments as needed.

Mounting the Switcher

The MAV component video models are housed in rack-mountable, 4U high, 17”
wide metal enclosures. The MAV S-video models are housed in 3U enclosures.
The MAV composite and audio-only models are housed in 2U high, enclosures.
The appropriate rack mount kit is included with each switcher. To rack mount the
switcher, do the following:

1. Insert the switcher into the rack, aligning the holes in the mounting bracket

with those in the rack.

2. Secure the switcher to the rack using the supplied machine screws.

Cabling and Rear Panel Views

All connectors are on the rear panel. The switcher can connect to up to as many as
16 component video, S-video, composite video and/or stereo audio devices,
depending on the model. The switcher can output to as many as 16 video and/or
audio outputs, depending on the model. Figure 2-1 shows a MAV 1616 component
video and audio switcher. Figure 2-2 shows a MAV S-video and audio switcher.
Figure 2-3 shows a MAV 1616 composite video switcher without audio. MAV 168
switchers are housed in the same 2U, 3U, or 4U enclosures as their MAV 1616
counterparts of the same video and/or audio type, but have fewer output
connectors to accommodate the different matrix sizes they provide. Figure 2-4
shows a MAV 1616 audio switcher. Figure 2-5 shows a MAV 128 RCA switcher.

Some devices, such as VCRs, can be connected to both input and output connectors
of the switcher. Others, such as tape players or CD players, can be connected only
to the audio input connectors. An audio device and a separate video device can
share an input; the switcher is capable of switching video and audio separately
(audio breakaway).

different video format, ensure that the same video planes are used on the
switcher output as on the input.

The MAV Series Switchers do not alter the video signal in any way. The
signal output by the switcher is in the same format as the input.

Audio input and output connections (audio models only)

The captive screw connector can easily be inadvertently plugged partially
into one receptacle and partially into an adjacent receptacle. This
misconnection could damage the audio output circuits. Ensure that the
captive screw connector is plugged into the desired input or output.

Audio input connections

MAV 128 RCA — Each input has a pair (left and right) of RCA connectors.
MAV 168/1616 — Each input has a 3.5 mm, 5-pole captive screw connector for

balanced or unbalanced stereo audio input. Connectors are
included with each MAV Series switcher, but you must supply
the audio cable. See figure 2-6 to wire a connector for the
appropriate input type and impedance level. High impedance is
generally over 800 ohms.

When making connections for the MAV Series Switcher
from existing audio cables, see figure 2-7. A mono audio connector consists of
the tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve.
The ring, tip, and sleeve wires are also shown on the captive screw audio
connector diagrams, figure 2-6 and figure 2-8.

The audio level for each input can be individually set, via the front panel
or RS-232/RS-422, to ensure that the level on the output does not vary
from input to input. See chapter 3, Operation, chapter 4, Programmer’s
Guide, and chapter 5, Matrix Software for details.

By default, the audio output follows the video switch. Audio breakaway, which is
commanded via the front panel (see chapter 3) or under RS-232/422 control, via the
SIS or Windows-based control program, allows you to select from any one of the
audio input sources. See chapter 3, Operation, chapter 4, Programmer’s Guide, and

If desired, attach an MCP 1000 remote control
panel master unit to the switcher’s RS-232/
RS-422 connector. You can also attach an
MKP 1000 remote keypad or MCP 1000 slave
unit to the MCP 1000 master unit. Refer to the

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and
chapter 5, Matrix Software for details on how to install and use the control
software.

The MAV switchers are factory configured for RS-232 control. To use the
switcher under RS-422 control, an internal cable must be moved. See
appendix B for the procedure for shifting the cable.

External sync connection

When the switcher switches between inputs, the resulting change in image should
be seamless, or clean. Video models of the MAV 1616/168 Series switcher can use
an external signal to synchronize switching during the vertical interval. Without
the external sync locking feature, switching between inputs can result in a brief
rolling (sync loss) or a brief change in the picture size.

applications.

External Sync Out connector — Connect any downstream equipment that
requires genlocking to this BNC connector to route the external sync signal
throughout the system in broadcast or other sync-critical applications.

Figure 2-9 shows a basic external sync configuration. The Ext Sync In connector
receives a timing signal. The Out connector allows the signal to be passed on to
another video device, if required.
