MAV 44 / 48 / 84 / 88 Matrix Switchers 1 Chapter One Introduction About the Switchers Features
Introduction, cont’d Introduction 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.

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.
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.

Installation, cont’d 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.
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.
Installation, cont’d 7 Balanced or unbalanced audio output connectors (captive screw audio connector [A] models only) — These 3.5 mm, 5-pole captive screw connectors output the selected unamplified, line level audio. Connect audio devices, such as an audio amplifier or powered speakers to these connectors. See figure 2-6 to properly wire an output connector. R Right 3/16” (5 mm) Max. Unbalanced Stereo Output Tip Ring Ground Tip Ring Left R Left L L Tip NO GROUND HERE.
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.
Installation, cont’d Figure 2-9 shows another configuration, in which the timing source passes through three video cameras and a video scan converter before connecting to the switcher. This type of video camera is capable of synchronizing with the external timing source for video editing applications.

Front panel security lockout (Executive mode) The MAV Series switchers have a front panel security lockout (Executive mode) feature that limits the operation of the switcher from the front panel and optional IR remote control. When the switcher is locked, the Enter button, I/O button (video only, audio/video, and audio only selection), and all of the front panel audio gain and attenuation functions are disabled.
Operation, cont’d Resetting the system to factory defaults (audio/video switchers) To reset an audio/video switcher to the factory default settings, press and hold the I/O button on the front panel while applying AC power (figure 3-43). Continue to hold the I/O button until all LEDs light and then release the I/O button. The power up sequence completes (all LEDs turn off then turn on and off from left to right, the Video and Audio LEDs turn on, and all other LEDs remain off).
Optimizing the Audio (Audio/Video Switchers) Each individual input audio gain can be adjusted within a range of -18 dB to +10 dB to eliminate noticeable volume differences between sources and to achieve the best headroom and signal-to-noise ratio. Adjust the audio level as follows: 1. Connect audio sources to all desired inputs and connect the audio outputs to output devices such as audio players. See “Audio input and output connections (audio/video models)”, in chapter 2, “Installation”.
Operation, cont’d Worksheets Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-31 and use one for each preset configuration. Cross out all unused or inactive inputs and outputs. If applicable, use different colors for video and audio. Worksheet example 1: System equipment Figure 3-44 shows a worksheet for a MAV 88 AV in a fictional organization with the system hardware annotated.
Worksheet example 2: Daily configuration Figure 3-45 continues from worksheet example 1 by showing the video and audio ties that make up the configuration of preset 1. A solid ink line shows video ties and a dashed pencil line shows the audio ties.
Operation, cont’d Worksheet example 3: Test configuration The A/V system in our fictional organization needs to be fine tuned on a regular basis.
