Economy and Versatility:

Extron’s Matrix 50 Series Switcher

(continued on page 2– See “Matrix 6400”)

Sixty-four signals in a single site—an

installer’s nightmare; a cable seller’s

dream-come-true. Computers, monitors,

projectors, cameras, VCRs, video

receivers, DVD, audio, and who knows

what else, all in close proximity and in

dire need of some kind of centralized

control. Does this sound familiar? Does

your latest installation use a number of

different signal types? Do you need to

distribute a large amount of signals as

well as route them? If so, then the Matrix

6400 series switchers are exactly what

you need.

The Matrix 6400 series includes

wideband/RGB, sync, audio, and video

models. The Matrix 6400 Video model is

a true 64 x 64 matrix with 80 MHz (-3dB)

of video bandwidth, fully loaded. It is

capable of 132 presets (32 global, 100

rooming) and will switch component,

S-Video, and composite signals, making it

With hundreds of items available for the

audio/visual professional, Extron occa-

sionally finds that a truly superior

product gets overlooked. The Matrix 50

Series Switcher is just that—one of our

most flexible and economic products

that every system designer should be

familiar with.

One word sums up the Matrix 50:

Versatility. Video configurations include

models for Composite video, S-Video,

and Component video (including RGsB)

at 80 MHz, with four available

input/output sizes: 12 x 8, 12 x 4, 8 x 8,

or 8 x 4. Balanced or unbalanced two-

channel audio switching is available in

the same sizes with any of these choices

or by itself without any video capabili-

ties. Altogether, this gives the Matrix 50

Series Switcher 28 possible configura-

tions, providing solutions for numerous

applications.

The Matrix 6400 Video System:

Unrivaled Simplicity and Flexibility

(continued on page 3– See “Matrix 50”)

In This Issue:

perfect for a large variety of A/V applications, including use with

HDTV. In addition, it features gen-locking for smooth transitions

between signal selection, non-volatile memory to make sure presets

are never lost, and a host of optional features such as an internal

redundant power supply, the MKP-1000 remote keypad, and our

highly intuitive FPC-1000 LCD front panel controller. But the

Matrix 6400 is more than just a switcher, it is a system that is

modular, field-upgradeable and expandable.

While each Matrix 6400 Video model comes standard with 64

inputs, it may be purchased with fewer outputs. This is made

EXTRONEWS JAN/FEB 1999 Extron’s Internal Promotion RGB 406 & RGB 440: Architectural Power by Mandi Speer, National Sales Manager At Extron, we are known for providing product solutions that meet the needs of our dealers and the A/V industry. In 1998, we introduced our 400 series architectural interfaces, and we are very pleased with the success of these products. As you probably know, our 400 series architectural interfaces do not automatically ship with a power supply.

EXTRONEWS JAN/FEB 1999 Matrix 50 – continued from page 3 Those looking for an external control method will be pleased to know that every Matrix 50 includes an RS-232/RS-422 serial communications port. This port may be used in conjunction with Extron’s Microsoft Windows™ based control software, which is also included with every Matrix 50. This package is able to duplicate all the functionality of the QuickSwitch™ Front Panel Controller, but with the convenience of the Windows™ graphical user interface.

EXTRONEWS JAN/FEB 1999 BNC-5 SuperFlex High Resolution Plenum-Rated Cable with Ripcord Extron’s BNC-5 SuperFlex HR Plenum Cable with Ripcord and sequential numbering offers a single solution to a situation with multiple needs: flexibility, plenum rating, easy in-field termination, and RGBHV distribution. Extron’s latest cable innovation is the built-in ripcord—it lowers the likelihood of cable damage during installation and makes stripping the cable for termination quicker, easier and more convenient.

EXTRONEWS JAN/FEB 1999 ICWK iMac Kit You need to display your iMac’s image on a projection screen or an external monitor—but the iMac doesn’t have an external video card output. What do you do? Use Extron’s ICWK (Internal Computer Wiring Kit) for the iMac. The ICWK iMac Kit provides interfacing of the iMac by externally routing the internal video monitor signals to an interface. Then a projector and/or monitor can be connected to the interface to display the iMac’s image.

EXTRONEWS JAN/FEB 1999 Notch Filter Decoders – continued from page 5 with reasonable results. In many situations, that approach is used today. In fact, most all of the digital decoders on the market automatically switch backand-forth between notch/bandpass and combing as required. Watching a VHS tape? You’ll most likely be operating in the notch/bandpass mode even if you have a comb filter in your display. Why is it called a notch/bandpass filter? Figure 2 illustrates the basic topology of this filter.

EXTRONEWS JAN/FEB 1999 the most noticeable examples are on the vertical edges of red lettering or other similar color objects. This artifact is referred to as cross-luminance. During moments when high frequency information, or horizontal detail, is present, some of this energy will find its way through the chroma channel. It presents itself as a “rainbow effect” in regions of the image having the high detail.

Extron Completes Its Family Of VSC 50 (Replaces the Emotia Jr. 800) Extron’s new line of scan converters, the VSC series, offers increased performance, easier operation, and improved features that provide the user with superior control over image quality. As the first in the VSC series, the compact VSC 50 is perfect for portable presentations, classroom displays, videorecording, and videoconferencing.

EXTRONEWS JAN/FEB 1999 3200/6400 MATRIX VIRTUALIZATION by Roger McCarten, Product Manager Last year, Extron introduced its new 32 x 32 and 64 x 64 matrix switchers, the Matrix 3200/6400 Series. These new switchers have been designed for ease of use. From the start, Extron’s engineers sought to design a matrix system that would be versatile and easy to upgrade—by the user.

EXTRONEWS JAN/FEB 1999 Audio Specs Spelled Out Audio specifications, exactly what do they mean? What is actually being measured? Most people in the A/V industry probably have a general idea of what common audio specifications mean. However, it is important to understand how each specification is measured and what the measurement specifically tells the reader about the performance of the equipment. In the following section a number of the more common audio specifications will be discussed.
PAGE 17
EXTRONEWS JAN/FEB 1999 Crosstalk is specified in dB, the level of the signal leakage. Crosstalk should be specified in relation to a particular frequency. Since crosstalk results from inductive and capacitive coupling, the degree of crosstalk will vary according to frequency. Therefore, crosstalk specifications should be compared at similar frequencies. Total Harmonic Distortion (THD) Total Harmonic Distortion is determined by measuring the amplitude of a series of harmonics.

EXTRONEWS JAN/FEB 1999 Unique Techniques: Disney Rolls Out DTV On November 1, 1998—a landmark day in the broadcasting and A/V industries— commercial broadcasting in digital and high definition television formats began in the United States. Among the networks taking part was ABC, which transmitted Disney’s 101 Dalmatians in 20 U.S. cities.

EXTRONEWS JAN/FEB 1999 Matrix 6400– continued from page 2 One might think that with this much power, configuring a system with as many as 384 input and output BNC connections might be difficult. While whoever is stuck with the crimper might not agree, this simply isn’t the case. With the help of Extron’s System Virtualization/Control Software, configuring for and controlling multiple switchers and signal types is not only possible, but fairly simple as well.

First, we would like to thank everyone who responded to the ExtroNews 1998 Annual Survey. We received more than 200 entries from as far away as Australia and Sweden. Some participants chose to fax in the survey; others in a hurry even sent them Federal Express, but most chose to mail them in with just a stamp and some finger-crossing.
