The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of
uninsulated “dangerous” voltage within the product’s enclosure that may be of sufficient magnitude to constitute a risk of
electric shock to humans.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating
and maintenance (servicing) instructions in this manual.

SAFEGUARDS

FCC INTERFERENCE STATEMENT NOTE:
This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the
FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in
accordance to the instructions, may cause harmful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by switching the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and the receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

- Consult the dealer or an experienced radio or TV technician for help.

Introduction

Congratulations and thank you for your purchase of this professional network audio controller. To get the most from your investment, we
recommend you review all the information provided in this User Manual.

The NAC-100 is a network audio controller allowing the system designer to create custom, graphical user interfaces using
QSControl.net™ Venue Manager version 3.1 (or higher) systems. Bridging the gap between simple switch closure or potentiometer
controls on one hand and sophisticated (and expensive) touch panel or computer-hosted control on the other, the NAC-100 will be at home
in hospitality, convention, transportation, entertainment, worship and educational facilities. The NAC-100 operates via PoE (Power Over
Ethernet, not included). Wiring consists of a single CAT-5 cable terminating to an RJ45 connector.

Creation of the custom, graphical user interfaces is accomplished within the Venue Manager environment where the system designer can
add Screens and Control Items. Each Screen can be thought of a menu of Control Items. Each Control Item can be used for recalling
Global Presets, screen navigation, and/or assigning the Rotary to Masters (Masters are created in Venue Manager and allow the system
designer to control various parameters of any number of audio channels). Operation and screen navigation are accomplished by means of
five push-buttons arranged in an intuitive left/right, up/down configuration plus a rotary encoder. When multiple NAC-100 controllers
control a single system, changes made from one unit will be reflected on the displays of others. For applications in which room diagrams,
corporate logos or other graphical elements are desired, the NAC-100 can support up to 15, full-screen bitmap images. Graphics and text
are displayed on a 3.5 inch (8.9 cm), backlit, color display with 320 x 240 pixel resolution. Chassis colors are available in black (NAC­100-BK) or white (NAC-100-WH), and the NAC-100 may be mounted directly to a wall surface.

NAC Features

• Easily create intuitive user interfaces from within QSControl.net™ Venue Manager software.

• Capable of displaying custom bitmapped graphics

• 16-bit, 3.5 inch (8.9 cm), backlit graphics display

• Five navigation / push buttons and rotary encoder

• Simple, single-wire connection using PoE (Power Over Ethernet)

Unpacking

There are no special unpacking precautions. However, it is recommended to keep the original packing material for reuse in the rare event
that service be required. If service is required and the original packing material is not available, ensure that the unit is adequately protected
for shipment (strong box of appropriate size, sufficient packing material to prevent load-shifting or impact damage) or call QSC’s
Technical Services Department for packing material and a carton.

What is included in the carton:

Item Description Quantity

1 NAC-100 1
2 Hardware Manual (this document) 1
3 QSControl.net Software CD 1

Mounting

The rear panel of the unit includes holes conforming to the hole patterns of numerous domestic and international electrical boxes.

ESD Warning

- Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic components are
improperly handled and can result in complete or intermittent failures.

- Always follow ESD-prevention procedures when removing the rear panel. Handle the NAC-100 by the outer edges of the chassis,
avoiding contact with the circuit board and components at all times. When inserting or removing the cable limit contact to plastic surfaces.
When mounting the rear panel ensure that the remaining hardware is placed with caution, avoiding static-causing surfaces such as carpeted
floors, plastic, and packing foam.

Computer Requirements & Software Installation

Installing QSControl.net is relatively simple. All that is necessary is to choose the folder where the program is to be stored (the default
setting is acceptable for most applications). It is recommended the system meet the following minimum requirements:

1- IBM PC compatible computer with a Pentium 4 processor.
2- Processor speed of 1.4 GHz (2 GHz or faster recommended for systems with 30 or more BASIS units).
3- 512 megabytes of RAM (1 gigabyte recommended for systems with 30 or more BASIS units).
4- Hard drive with at least 500 MB of free space for the program and files you generate.
5- Display resolution of 1024 X 768, 16-bit color.
6- CD-ROM drive to install the software.
7- 10BaseT/100BaseTx network interface card
8- Windows XP Professional, XP Home, and Windows Vista operating systems. Windows 95, 98, 2000, NT4, and ME platforms are not
supported.

Note: If system is used for real-time adjustments and configuration of audio systems, it is recommended that all Windows Power Options
(located in the Windows Control Panel) features be disabled. Display, hard drive, system standby and hibernation settings should be set to
“Never”. This avoids waiting for the system to “wake-up” if adjustment is needed after an elapsed period of time.

To Install QSControl.net:

1

- Start computer and start Windows.

2- If there are any programs running, please close them now. Be sure to leave Windows running.
3- Place the QSControl.net CD-ROM in the CD-ROM drive. It is also possible to select Start-Run and browse for the file named setup.exe
on the CD.
4- Click the Install QSControl.net button.
5- Follow the installation instructions on the screen.

To Uninstall QSControl.net:

1- Click the Start menu button and choose Settings/Control Panel.
2- Double-click the Add/Remove Program icon.
3- Select QSControl.net from the list, then click Add/Remove.
4- Click Yes to begin uninstalling QSControl.net.

Connections

1-Gently separate the NAC-100 from its rear panel using the side tabs.

2-Run the category-5 cable through the access hole in the center of the NAC-100.

3-Connect one end of a category-5 cable terminated with an RJ45 plug into the RJ45 receptacle on the circuit board of the NAC-100 by
inserting the RJ45 plug into the receptacle with the lock-tab oriented away from the circuit board. Push firmly until the connector locks
into place (usually an audible “click” can be heard).

4-Connect the other end to the appropriate QSControl.net network port. (See the Networking Diagrams included later in this manual.)
