INTRODUCTION
The Matrix System®
Audio/Video Switching for the Retail Environment
Audio/Video consumers today get more information, more choices, more “advice” from magazines and
word-of-mouth than ever before. The retailer who can demonstrate a great variety of systems with ease,
style, and to the performance limits of each individual component, will be the retailer who will sell the most
product. MTi‘s Matrix System®with the MVP Control Panel gives you the power, control, and flexibility you
need to demonstrate all components in the car audio, home audio, video and home theater markets.
Figure 1 – Typical Matrix Applications

Introduction
10
With a Matrix System®at work in your showroom, your sales staff can demonstrate your entire lineup of
products while concentrating on the customer and his or her needs. Your customers can make comparisons
between different manufacturers, prices, and/or component options and will feel confident in their
selections.
It’s easy to command the power of the Matrix System®. By selecting numbers on the MVP Control Panel for
each component desired, up to 16 different types of electronic components can be interconnected and
activated at one time. (Even more capability may be possible with custom designs.)
Standard features include:
•Up to 30 programmable component combinations (System 1-30)
•A/B System Compare, which lets the user toggle between two user-chosen combinations
•Auto-Rotate, which rotates the audio/video signal through any chosen group of
components
•Selectable Speaker Dropout Delay Timing, which prevents Speaker “popping” when
components are selected
•Component Chain labeling system for ease in component selection
•Lock-Out, which prevents unauthorized use of the System
Optional features include: a hand-held MVP Infra-Red Remote Control, which allows you to control your
entire System from the palm of your hand; a Watt Meter; a Sound Pressure Meter; and a Speaker Equalizer
(see pages 27-36 for a detailed description of these features).
Using This Manual
This manual has been organized for all MTi customers, with special emphasis for those new to the Matrix
System®. However, there’s something in here for everyone: from the potential Matrix owner, to the store
manager who needs to add some components to an existing System, to new employees who need to
operate the System.

You don’t need to be an Audio/Video expert to succeed with the Matrix System®. To use or program this
System, all you really need to do is follow the steps outlined in the Operation Section. To install, connect
components to, or service a Matrix System®, some fundamental understanding of audio/video products and
their proper connection will be necessary. Such as:
1. A basic knowledge of Audio and/or Video components and their signals.
2. The ability to read simple signal flow diagrams. We recommend that you study the System
Diagrams found in the Matrix System® Installation section of this manual that are applicable
to your situation. This should aid you tremendously in visualizing your finished product.
3. Effective wire connection technique, including stripping, crimping, using bullet connectors,
soldering, etc. It is extremely important to be careful and methodical when wiring your
System to avoid ground loops, intermittent shorts, or other problems that can plague the
display in the future. See pages 59 in the Matrix System® Installation section for more
information.
But if the whole project turns out to be more of a challenge than you’re ready for, remember that our Field
Service Technicians can come to your location to help you with your installation and/or service. Call MTi
Customer Service for more information (see below).

MEET THE MATRIX SYSTEM®
There is one central idea underlying the Matrix System®from MTi — that you should be able to
demonstrate any and all of the components in your System as they were meant to be demonstrated,
in any combination, with minimum effort. We have engineered the logic into our switching systems to
give you maximum flexibility and selling power.
What is a Matrix?
The dictionary defines a matrix as “a rectangular array of elements arranged into columns and rows.” In a
Matrix System®, the columns are Chains of Switching Modules controlling similar components, (e.g.,
Decks, Amplifiers, Speakers) and the rows consist of Positions on the Switching Modules with components
connected to them. The path along which signals flow between Chains is called the Bus. (Some systems
may have more than one bus.) The Matrix System®enables you to activate any component(s) within the
“matrix” by selecting the desired component’s horizontal (position number) and vertical (Chain name)
coordinates.

Figure 3 – The Matrix Concept

Introduction

Because of this design, you can create a demonstration system from any combination of compatible
components in your display. Select components by simply entering their Position number and pressing the
correct Chain selection button. As soon as an appropriate signal reaches an output device (Speakers or a
Monitor), the system will begin to play.
Each Matrix System®is composed of two major elements:
1. The MVP Control Panel, which consists of the MVP Control Module, one or more Dual
Chain Modules, and optional Feature Modules.
2. The Switching Modules, which provide the connection points for the audio/video
components and perform the actual signal switching.
The MVP Control Panel, the nerve center of the System, allows the user to send commands to the Switching
Modules that activate specified relays.
The Switching Modules, the muscles of the System, contain either one or two sets of eight relays. Each relay
is provided with terminals for connecting input and/or output signals. Some Modules also have terminals for
the connection of 12V turn-on (trigger) for Autosound components if required. Switching Modules may be
connected serially in a Chain to provide switching for more components in groups of eight. (For example, a
Front Speaker group with 12 Speaker pairs would require two Modules to form the Chain.) Should a
component require more connection points (e.g. multi-channel outputs) than a particular Switching Module
offers, additional Switching Modules can be added and assigned the same selection number.
Passive Switching
All MTi switching products are passive switching systems, which do not affect in any way the audio/video
signal that is being switched. This ensures that any audio or video component being demonstrated with one
of our systems exhibits its true range of capability.
Switching Capacity
The MVP Control Panel can connect up to 16 separate Chains of Switching Modules, allowing you to
demonstrate 16 different types of components together within one System. Each Chain can switch up to 99
Components – e.g. 99 Decks, 99 Sub Amps, 99 Rear Speakers.
By The Numbers
The microprocessors that control the Matrix System®require that each Module and component Position has
a number. The Module number is like the street address of an apartment building, and the Position number
is like an apartment number in that building. These numbers allow the MVP Control Panel to locate and
identify each component in the System. They are assigned during installation by setting DIP switches
located on each Switching Module.

Matrix System®
15
Bypass
The first Position (A Position) of the first (-1) Module in a Chain can be used as a bypass to allow the Bus a
route to pass a signal through a Chain that has no components selected (generally used for processor-type
components, such as Amplifiers and Equalizers). Although each Module can switch up to eight components,
the first Module in a Chain that has a bypass would switch only seven.
Switching for All Applications
Because audio/video components differ in their input/output requirements, MTi manufactures a number of
different Switching Modules, each with a different configuration of input/output capabilities. (See Figure 20,
page 39, for a complete listing.) Each Module contains one or two sets of eight component connection
Positions, plus input/output Bus connections. Some Modules switch only low-level signals, some only high,
and some have sets of low- and high-level connectors on the same Module. The Matrix®product line also
includes Switching Modules with various other connectors.

PRODUCT DESCRIPTIONS
The MVP Control Panel
A typical MVP Control Panel consists of a single MVP Control Module and several Dual Chain Modules, one
for each two Chains in your System. In addition, you may have chosen to include Feature Modules in your
System, such as Watt Meters, and a Sound Pressure Meter with Speaker Equalizers (see pages 27-33).
The MVP Control Panel is the nerve center for all the functions of the Matrix System®. The user selects
individual components for a demonstration by entering the numbers which correspond to each component
using the MVP Control Panel buttons (or with the Remote Control Unit, see page 35).

For example, the System operator would select a source by entering its number, e.g. tape player 12. The
number 12 will be displayed in the LED window of the main MVP Control Panel. The operator then selects
the source Chain by pressing its button, and the component number 12 transfers to the LED window of the
Source Chain Module. The operator then continues to choose the rest of the components to be
demonstrated, Chain by Chain. As soon as a signal reaches a destination component, (e.g. a source/
Amplifier/Speaker combination), the system will begin to play. Additional components can be added or
changed while the system is operating.
NOTE: The Matrix System®has a Speaker Dropout Delay Timing feature which cuts off the signal to the
Speakers for a programmable time period when components are entered or changed to prevent
Speaker popping (See page 122 for more information.)
Matrix System®MVP Features
Following is a listing of the main features that help make the Matrix System®the most flexible, complete
and simple-to-operate demonstration system available.
Component Selection –
By entering a Component number with the numeric keys on the MVP Control Module, and then pressing a
Chain button, components can be activated.
Display Windows –
Located in the upper right-hand corner of the MVP Control Module and above each button of each Chain
Module is a Display Window. These displays verify the entries made on the MVP Control Panel by displaying
alpha, numeric and graphic confirmations of those entries. If any programming, selection or activation
function is not properly completed within three seconds of the last key entry, both the display and the
function will time out and clear. The display will also clear from the MVP Control Module window after a
Chain Selection Button (on a Dual Chain Module or Feature Module) is pressed. The displayed selection
number then transfers to the selected Chain display clearing the main MVP Control Panel display for the
next entry.
A/B Compare –
Enables the user to toggle between two component systems for comparison. Store a complete combination
of components under button ‘A’; store a variation of ‘System A’ or a completely different system under
button ‘B’; then by alternately pressing the “Compare” A and B buttons you can toggle between Systems. A/
B Compare is designed to be programmed during a demonstration, since it can easily be changed to satisfy
the interests of each new customer. (See page 112 for operation.)
System 1–30 –
Thirty different combinations of audio/video components can be stored with the recall numbers 1 through
30. This feature can be used for storing frequently sold components or systems, advertised and in-store
specials, loss leaders, etc. Stored systems can be activated with two or three key strokes. (See page 113 for
operation.) System 30 is the default system when the Inactivity feature is engaged. When System 30 is not
programmed, the MVP Control Panel will be idle.

Matrix System®
19
Component Auto-Rotate –
Activating this feature allows the MVP Control Module to automatically rotate (at programmable intervals)
any quantity of components within a Chain, in a pre-chosen low to high sequence. This feature can be used
to demonstrate different performance characteristics of a group of like components in product
demonstrations for customers or during sales training. Or activate Auto-Rotate when the System is idle to
attract customer attention and create excitement. (See page 116-117 for operation.)
System Lock-Out –
To protect against unauthorized use or to ensure control of the sales process, the control panel can be
locked by entering a two digit number with the numeric keys and then pressing LO. This number can be
any two digit combination and can be changed at any time. (See page 110-111 for operation.)
NOTE: The Lock-Out feature may be activated while leaving a selected audio/video system playing.
System Inactivity Time –
If desired, the MVP Control Module can be set to automatically clear all entries after 1-99 minutes of
component selection inactivity. This feature will cancel any selections left active on the System, preventing
unwanted audio/video programs from continuing when store personnel are busy elsewhere. The Inactivity
feature is activated by setting a DIP Switch on the back side of the MVP Control Module. (See page 122 for
DIP Switch setting instructions.)
NOTE: If the Lock-Out feature has been activated with a component system playing, Inactivity is disabled.
Memory Backup –
The MVP Control Module has an internal electronic memory backup that will retain all System programming
should a power interruption occur. When power is again restored to the MVP Control Module, any and all
systems stored in memory, Component Auto-Rotate parameters, etc. will be available as previously
programmed.
