Installation
76
If you are using component connection terminals, install them now and run wires and/or cables between
the component positions on the Switching Modules and these terminals. Review “Wiring Techniques” on
page 61 for specific guidelines, and see page 78 for a diagram of an installed Power Supply.
NOTE:
Do not connect components
to component connection terminals at this time – this will be done
systematically during the final stages of installation and testing to ensure that the entire System is
hooked up properly. If you are running cables and wires directly between components and
Switching Modules, do not make connections now. Wait until the final installation and testing stage.
2. Switched Autosound Component Power Installation
Autosound components can be connected directly to a Power Supply and remain activated all the time the
display is powered up. However, MTi’s Switching Modules allow you the
option
of simultaneously powering
up your car audio equipment as it is selected as part of a demonstration system (the way it works in a car).
Especially with head units, this provides an easy way to see which component is selected, and the
customer’s attention is focused on the selected unit, rather than being distracted by the entire display. In
addition, a large display can draw quite a lot of power when all components are powered up constantly,
which makes less power available in reserve for system demonstrations.
Component Turn-On can be accomplished either with the Switching Modules that have on-board
component turn-on relays (see page 39), or with the optional 0102 Accessory Module (see page 57). To
determine power requirements for your components, use the Power Supply Requirement Worksheet in
Appendix B.)
2.a Installing the Component Power Supply
Figure 40 illustrates a method for hooking up 12V DC power. This is the way MTi wires displays
at the factory, and we feel it offers the most efficient and safest transfer of power. In addition,
this method makes disconnection and reconnection of components quick and easy – a real plus
if your display’s components are changed often.
If you are using MTi’s PDQ Component Quick Connects for decks and EQs, all the necessary
power and signal connectors are included, and all you have to do is make connections from the
Power Supply and the Switching Module Chains. (See page 59.)
2.1 Mount the Power Supply securely in the display. Make sure there is easy access to the on/
off switch
and
the fuse holder.
2.2 Connect dual 10 gauge wires to the positive and negative terminals of the Power Supply
using ring connectors. Then connect these dual wires to positive and negative terminal
blocks. More than one positive and negative terminal block may be “daisy-chained” if you
are connecting a large number of components. This can prevent a thick bundle of wire and
also make it easier to trace any shorts.
2.3 Connect each Component’s Ground, Memory, and Switched 12V wires to a three-position
terminal block (or PDQ or Push Terminals) mounted near the component. The Switched
12V position is connected to the lettered terminal on the Component Turn-On Strip of the
Switching Module which switches that component. The +12V constant or Memory position
from the component terminal block is connected directly to the Positive power terminal
block. The Ground position is connected to the Negative terminal block. Now, when the
component is selected at the MVP Control Panel, it is activated as well.
