Manual and Installation Guide
Overview
Introduction
ProSwitch modules are used to create interactive product demonstration displays which can be intuitively
operated by a salesperson or customer without instruction or special technical knowledge. ProSwitch
modules switch low level (RCA), high level or high current (ie subwoo ers and high power ampli iers) signals,
and can be combined to create scalable audio/video systems rom small stand-alone displays to large car-audio
rooms.
A button and LED is placed next to each device, component or speaker, to be selected by the ProSwitch
system. Pressing the button allows the user to select or deselect that device. When a new device is selected
any previous devices o the same type are automatically deactivated. The LEDs will light when its associated
device is active, giving the user a visual indication o which devices are currently selected.
Overview
ProSwitch Modules
ProSwitch systems are comprised of four types of modules:
1. Main Module (PRSW-MCU-PCB): Main Modules read button presses and communicate with other
Main Modules in the system. They control and synchronize ADD- N signal modules. Each set of four
components or speakers to be switched requires one Main Module.
2. High Level DD-ON Module (PRSW-4HL-PCB): High Level Modules (4H) switch high level signals up to
7A MAX (196 Watts for a typical 4 ohm speaker), such as speakers, head unit outputs or amplifier
outputs. Each module switches L+/L-, R+/R- for four positions. High Level Modules can be ordered
with MTA connectors which use a specialized crimp tool to connect wiring, or with simple screw
terminal blocks which only require a screwdriver to use.
3. Low Level RC DD-ON Module (PRSW-RC -PCB): Low Level Modules (4L) switch low level RCA
signals, such as amplifier inputs or head unit RCA outputs. Each module switches Left/Right RCA signals
for four positions.
4. High Current Mono DD-ON Module (PRSW-MONO-PCB): High Current Modules (HC) switch high
current mono signals up to 16A MAX (1024 Watts for a typical 4 ohm speaker), such as sub woofers and
high-power amplifiers. Each module switches +/- mono signal for four positions.
For each set of four components or speakers, one Main Module is used, plus ADD- N Modules as required to
switch all associated signals. For example, a set of four speakers would require one Main Module and one High
Level Module. A set of four 4-channel amplifiers would require one Main Module, two Low level Modules and
two High Level Modules.
Additional modules are available to add to ProSwitch systems to provide advanced functions, such as Feature
System Module PRSW-FEAT-PCB, which allows four complete system settings to be programmed and then
recalled at the touch of a single button.

Main Module PRSW-MCU-PCB
Figure 1: Main Module PRSW-MCU-PCB
Main Module PRSW-MCU-PCB (Figure 1) is used to read push-buttons and communicate with other modules in
the system. Each set of four components or speakers requires one Main Module. It controls and synchronizes
ADD- N modules to switch signals. DIP switches are used to set the Module’s address and other functions.
Remote turn-on power can be supplied using the Component Remote Turn-on Power Connectors (5A MAX).
This allows only active components to be turned on to save power and allow a smaller system power supply.
This is the method recommended by AudioStak.
The Active LED indicates when the module has an active position or flashes in different modes as a
troubleshooting aid in the event of a wiring error or module failure.

High Level ADD- N Module PRSW-4HL-PCB (Figure 2) is used for switching high level signals up to 7 Amps MAX
(196 Watts for typical 4 ohm speaker), such as speakers, head unit outputs or amplifier outputs. Each module
will switch L+/L-, R+/R- for 4 positions (speakers or components).
To switch signals higher than 7 Amps, use High Current ADD- N Switching Module PRSW-M N-PCB.

connections. For high current stereo applications, two High Current Modules can be used: one for Left +/-, and
one for Right +/-.

Groups
In a ProSwitch system, audio/video products must be arranged into Groups of similar devices. For example,
head units would be one Group, front spea ers would be another. Each Group is then given a Group Number,
which set through the DIP switches on the Main Modules (PRSW-MCU-PCB). ProSwitch systems can have up to
16 groups of spea ers, and up to 16 groups of components. A 'component' is any non-spea er device.
Boards
Within each Group it may be necessary to use multiple Main Modules depending on the number of products
involved. Each Main Module is able to switch up to four products. For each additional four products in that
Group, one more Main Module is needed. ADD-ON modules are connected to each Main Module to switch the
signals required by that Group. Each Main Module within a Group is given its own number, called its Board
Number. This is set using its Board Number DIP switch.
Positions
Each Main Module, together with its attached ADD-ON modules can switch up to four devices (spea ers or
components). The signal connectors on the ADD-ON modules and the button connectors on the Main Modules
are all labelled A through D, and are referred to as Positions. When a button connected to Main Module is
pressed, all the signal connectors on its attached ADD-ON modules with the same Position number are selected
and become active. Each component must have all its signal connectors connected to the same position, A, B,
C, or D, on each ADD-ON module.
For example, in a 2-channel amplifier Group each Main Module would use two ADD-ON modules: one 4L
module (PRSW-RCA-PCB) for RCA inputs, and one 4H module (PRSW-4HL-PCB) for high level outputs. When the
button connected to Position A on the Main Module is pressed, Position A on that Board becomes active, and
all other Positions within that Group are deselected and disconnected. The RCA inputs for that amplifier
connected to Position A on the 4L board will become active, as well as its high level outputs connected to
Position A on the 4H board.
The signal connectors for the four Positions on each ADD-ON module can be used for either input or output
signals. For example, 4H modules are used to switch the high level outputs from head units and amplifiers, as
well as the high level input signals to spea ers.
Overview – Groups, Boards and Positions
Main Module Address
Each Main Module has an Address which is made up of the Group Number, Board Number and device type
(Component or Spea er). These are all set using the DIP switches on the Main Module, shown in Figure 5.
The switch labelled 'COMP' and 'SPKR' is used to set the device type. All spea ers and sub woofers should be
set to ‘SPKR’. All other devices should be set to ‘COMP’. Spea er Groups and Component Groups are handled
separately by the ProSwitch system, so this switch can also be considered as part of the address.
Figure 5: Main Module DIP Switches
The Group Number DIP switch on each Main Module is used to identify which Group it belongs to. Within each
Group, multiple Main Modules may be required depending on the number of products in that Group. Each
Main Module is given a different Board Number which is set using the Board Number DIP Switch.
ProSwitch systems can have up to 16 Groups of components, and 16 Groups of spea ers. Within each Group
there can be up to 16 Boards. Group Numbers and Board Numbers are assigned using the DIP switches as
shown in Figure 6.
When a Position is selected, all other Positions within its Group are automatically turned off before that
selected Position is activated. Pushing the button for an active Position will cause it to be deselected and turn
off.
Normally each Main Module will have its own unique Address, different from all other Main Modules in the
system. If two Main Modules are both set with the identical address, they will echo each others actions and
switch in unison, so if a position on one Main Module was selected, that position would become active on both.
This is generally not desirable, but may be used in some special applications.
