About the Switchers

The Extron MAV Series AV matrix switchers (figure 1-1) are a family of broadcast quality matrix switchers that distribute any composite video or S-video input with audio to any combination of outputs. The MAV Series switchers can route multiple input/output ties simultaneously. The MAV Series switchers have a wide array of input and output configurations, video formats, and audio connections. Depending on the model, the switchers route a combination of S-video or composite video with audio on captive screw or RCA connectors.

The MAV 88 matrix size has models without audio.

Features

Video features

S-video (SV) models — These switchers input and output NTSC 3.58, NTSC 4.43, PAL, or SECAM S-video (luminance [Y] and chrominance [C]) signals on 4-pin female mini DIN connectors.

Composite video (V) models — These switchers input and output NTSC 3.58, NTSC 4.43, PAL, and SECAM composite video signals on female BNC connectors.

Bandwidth (SV and V models) — Bandwidth is 150 MHz (-3 dB). This high bandwidth allows the switchers to switch all of the quad-standard video formats with no loss of signal quality.

Vertical interval switching — The switcher can use a black burst (genlock) signal to synchronize switching during the vertical interval. This ensures glitch-free switching among multiple timed sources.

Introduction, cont’d

Audio features

Captive screw audio connector (A) models — These switchers input and output balanced or unbalanced stereo audio signals, on 3.5 mm, 5-pole captive screw terminals.

RCA audio connector (A RCA) models — These switchers input and output unbalanced stereo audio signals on left and right RCA connectors.

Audio input gain/attenuation — You can set the level of audio gain or attenuation (+10 dB to –18 dB) via the RS-232 port or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. This function also eliminates the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment.

Audio output level switch — The audio level of each output can be set to either –10 dBV (consumer level) or +4 dBu (pro level) via RS-232 control only.

Audio follow — In audio/video switchers, audio can be switched with the corresponding video input. Audio follow switching can be done via front panel control, optional IR 501 control, or the RS-232 port.

Audio breakaway — In audio/video switchers, audio can be broken away from its corresponding video input signal. Audio breakaway switching can be done via front panel control, optional IR 501 control, or the RS-232 port.

Common features

Switching flexibility — Provides individually buffered, independent matrix switched outputs with audio follow and audio breakaway for audio versions.

•Any input to any or all outputs

•Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time.

Operational flexibility — Operations such as input/output selection and setting of presets can be performed on the front panel, via the RS-232 port, or using the optional IR 501 small matrix universal remote control. The RS-232 port allows remote control via a PC or control system.

•Front panel controller — The MAV series front panel controller feature supports touch-of-a-button input and output selection, preset creation and selection, and audio gain and attenuation control.

•RS-232 control — The switcher’s RS-232 port allows remote control via a PC or control system using Extron’s Simple Instruction Set (SIS™) or the included Windows®-based control program.

•Optional IR remote control — The MAV switchers are remote controllable, using the optional small matrix IR remote control.

The switcher’s IR receiver is disabled by default and must be enabled to use the IR remote control. See the IR receiver enable SIS command in chapter 4, “Remote Operation” to enable the IR receiver.

Upgradeable firmware — The firmware that controls the switcher’s operation can be upgraded in the field via the RS-232 port, without taking the switcher out of service. Firmware upgrades are available for download on the Extron Web site, www.extron.com, and they can be installed using the Windows-based control program.

1-4 MAV 44 / 48 / 84 / 88 Matrix Switchers • Introduction

Global memory presets — 16 global memory presets are a time-saving feature that lets you set up and store input/output configurations in advance. You can then recall those configurations, when needed, with a few simple steps. On each model, there are as many presets available from the front panel as there are input and output buttons:

•MAV 44s have 8 presets available on the front panel.

•MAV 48s and MAV 84s have 12 presets available on the front panel.

•MAV 88s have 16 presets available on the front panel.

On smaller MAVs, presets that are not available from the front panel are still available under RS-232 or optional IR 501 control.

Rack mountable — With the included rack mounting kit, the switchers can be mounted in any conventional 19” wide rack.

Under-desk mountable — With an optional desk mounting kit, the switchers can be mounted under a desk, podium, or other furniture.

Front panel security lockout (executive mode) — If a MAV Series switcher is installed in an open area where operation by unauthorized personnel may be a problem, a security lock-out feature can be implemented. When the front panel is locked, a special button combination is required to unlock the front panel controller before it can be operated. Ties can still be viewed.

When the front panel is locked out, the switcher can still be operated via the RS-232 link.

Power supply — The matrix switchers’ internal 100 VAC to 240 VAC, 50/60 Hz, 15 watts, auto-switchable power supply provides worldwide power compatibility.

Mounting the Switcher

Keep the switcher out of bright light to prevent interference with the IR signals from the IR 501 remote control.

Tabletop use

For tabletop use, affix a self-adhesive rubber foot to each corner of the bottom of the switcher.

Rack mounting the switcher

UL requirements

The following Underwriters Laboratories (UL) requirements pertain to the installation of the matrix switcher into a rack (figure 2-1).

1.Elevated operating ambient temperature — If installed in a closed or multiunit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

2.Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

3.Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

4.Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

5.Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

Mounting instructions

All of the MAV Series AV switcher models are housed in rack-mountable, 1U-high, full-rack wide metal enclosures. The appropriate rack mounting kit is included with each switcher. Rack mount the switcher as follows:

1.	If feet were previously installed on the bottom of the switcher, remove them.
2.	Attach the rack mount brackets to the switcher with the eight #8 machine
	screws provided (figure 2-1).
3.	Insert the switcher into the rack, aligning the holes in the mounting bracket
	with those of the rack.
4.	Secure the switcher to the rack using the supplied machine screws.

Furniture mounting the switcher

The MAV Series switcher models can be mounted under a table or other horizontal surface with an optional Extron under-desk mounting kit (part #70-222-01).

1.	Secure the two table/wall mounting brackets to the switcher with the eight
	machine screws provided in the kit (figure 2-1).
2.	Hold the switcher with attached brackets against the underside of the desk or
	other furniture. Mark the location of holes for screws on the underside of the
	desk.
3.	Drill 1/4" (6.4 mm) deep, 3/32" (2 mm) diameter pilot holes in the table or
	desk at the marked screw locations from the underside/inside (concealed
	side) of the furniture, where the switcher will be located.
4.	Insert the four wood screws into the pilot holes. Fasten each screw into the
	installation surface until just less than 1/4" of the screw head protrudes.
5.	Align the installed screws with the slots in the mounting brackets, and place
	the switcher against the surface, with the screws through the bracket slots.
6.	Slide the switcher slightly forward or back, then tighten all four screws to
	secure it in place.

Cabling and Rear Panel Views

All connectors are on the rear panel. The switcher can be connected to up to eight S-video, composite video, and/or stereo audio sources, depending on the model. The switcher can output to up to eight S-video, composite video, and/or audio devices.

Figure 2-2 shows a MAV 44 AV composite video and audio switcher. Figure 2-3 shows a MAV 88 SVA RCA S-video and audio switcher. All of the switchers are housed in the same 1U enclosures, but have more or fewer input connectors to accommodate the different configurations they provide. The two switchers shown have all of the connector types that are available in the MAV AV product family covered in this manual.

Some devices, such as VCRs, can be connected to both video and audio 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, because the switcher is capable of switching video and audio separately (audio breakaway).

2-4 MAV 44 / 48 / 84 / 88 Matrix Switchers • Installation

Audio input and output connections (audio/video models)

The audio level for each input can be individually set, via the front panel or RS-232, to ensure that the level on the output does not vary from input to input. See chapter 3, “Operation”, and chapter 4, “Remote Operation” for details.

By default, the audio follows the video switch. Audio breakaway, which is commanded via the front panel, under RS-232 control via the SIS or Windowsbased control program, or optional IR 501 control, allows you to select from any one of the audio input sources. For details, see chapter 3, “Operation”, and chapter 4, “Remote Operation”, and refer to the IR 501 Small Matrix IR Remote Control User’s Guide.

5Balanced or unbalanced audio input connections (captive screw audio connector [A] models only) — 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 AV captive screw connector switcher, but you must supply the audio cable. See figure 2-4 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 5 k ohms.

Figure 2-4 shows two methods of wiring the captive screw audio connectors for input and figure 2-6 shows two methods of wiring the connectors for output. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring, and sleeve. If you are wiring a captive screw connector from an existing unbalanced audio cable, the white insulated wire is typically the left channel (tip) and the red insulated wire is typically the right channel (sleeve). There is no reliable standard for existing balanced audio cables.

Figure 2-7 — RS-232 port pin assignment

The cable used to connect the RS-232 port to a computer or control system may need to be modified by removing pins or cutting wires. If you encounter problems while operating under RS-232 control (the switcher may hang up), pins 1, 4, 6, 7, 8, and 9 may need to be disconnected. Either cut the wire to pins 1, 4, and 6 through 9 in a hard-shelled connector or remove pins 1, 4, and 6 through 9 from a molded plug.

See chapter 4, “Remote Operation”, for definitions of the SIS commands and details on how to install and use the control software.

2-6 MAV 44 / 48 / 84 / 88 Matrix Switchers • Installation

Using the hardwired IR input on pin 9, you can use a control system with IR-learning capabilities to operate the switcher just as if you were using an IR 501 remote control. The control system must first “learn” the IR command from an IR 501, after which it sends the same commands to the MAV via

pin 9.

External sync connection

The MAV switcher switches between inputs during the vertical interval period, resulting in glitch-free video switching. The MAV 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.

10Sync In connector — Connect an external genlock signal to this BNC connector for genlocking the video signal in broadcast or other sync-critical applications.

11Sync 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 2-8 shows a basic external sync configuration.

Front Panel Controls and Indicators

The number of input and output buttons and LEDs and other controls and LEDs that are present on each MAV Series AV matrix switcher vary with the number of inputs and outputs and whether the switcher has video only or both video and audio. Not every switcher has every control or indicator described in this chapter.

In the following descriptions, you will find the following terms:

•Video-only switcher — Switches S-video or composite video only and has no audio capabilities.

•Audio/video switcher — Switches either S-video or composite video and audio.

Figure 3-1 shows the front panel of an 8-input, 8-output video-only switcher. Figure 3-2 shows the front panel of a 4-input, 8-output video and audio switcher. These examples show all of the control and indicator combinations that you may encounter with your particular switcher.

Many of the buttons and LEDs on figure 3-2 have dual functions.

Definitions

The following terms, which apply to Extron matrix switchers, are used throughout this manual:

Tie — An input-to-output connection

Set of ties — An input tied to two or more outputs. (An output can never be tied to more than one input.)

Configuration — Consists of one or more ties or one or more sets of ties

Current configuration — The configuration that is currently active in the switcher (also called configuration 0)

Global memory preset — A configuration that has been stored. Up to 16 global memory presets can be stored in memory. The input and output buttons are used to select the desired preset memory location to load or retrieve a preset. When a preset is retrieved from memory, it becomes the current configuration. On each model, there are as many presets available from the front panel as there are input and output buttons:

•MAV 44 models have 8 presets available on the front panel.

•MAV 48 and MAV 84 models have 12 presets available on the front panel.

•MAV 88 models have 16 presets available on the front panel.

On smaller MAV models, presets that are not available from the front panel are still available under RS-232 or optional IR 501 control.

Power/audio/data LED and infrared sensor

1Infrared remote sensor — This sensor receives infrared (IR) signals from the optional IR 501 small matrix universal remote control. The IR remote control must be pointed within 30 degrees of this sensor for best results.

Operation of the IR 501 remote control is described in the IR 501 Small Matrix IR Remote Control User’s Guide.

The switcher’s IR receiver is disabled by default and must be enabled to use the IR remote control. See the IR receiver enable SIS command in chapter 4, “Remote Operation” to enable the IR receiver.

Keep the switcher out of bright light to prevent interference with the IR signals from the IR 501 remote control.

2Power/data/audio LED —

•When lit, the Power LED indicates that power is applied to the matrix switcher.

•When blinking off and on, the Power LED indicates that an IR signal has been received.

•In Audio Setup mode, the Power LED also serves as an audio meter that is tied to output 1. The LED blinks frequently when the selected input’s audio level has been adjusted to the –10 dBV internal reference level. (In Audio Setup mode, the selected input’s audio is automatically tied to output 1.) See “Adjusting input audio gain and attenuation” on

page 3-19 and “Optimizing the Audio (Audio/Video Switchers)” on page 3-27.
