Installation
The ADX is easy to set up for both simple and advanced installations. Perform the following steps.
Installing the ADX
The ADX is conveniently designed so that it may be installed either on a shelf or in
a standard 19-inch equipment rack. If rack mounting, remove the feet and the cover
screws adjacent to the front panel of the unit. Reuse the cover screws to mount the
Model 1192A rack adapters supplied with the ADX. Be sure to place a spacer under
the adapters at every screw location. Secure the ADX to the rails of the equipment
rack with the screws supplied with the rack adapter kit.
Initial Audio Setup
Independently test each component to be connected to the ADX prior to system assembly. This will greatly reduce
time-consuming troubleshooting measures later. Verify basic ADX functionality by performing the
following steps:
1. Connect one source unit to a pair of input jacks numbered 1-8.
2. Connect one audio receiver to a pair of zone output jacks numbered 1-8.
3. Use high quality cable and keep the lengths as short as possible.
4. Turn on the source, receiver and the ADX for an initial test. Verify the audio pathway is performing acceptably by selecting
the appropriate source input and zone output from the front panel (detailed instructions for Front Panel operation can be
found on page 10). You should now hear the source material being played. If you do not, please refer to the
Troubleshooting section found on page 16. If you are still experiencing difculty, please contact Technical Support by
phone at 859-233-4599 or toll free in the US at 1-800-322-8346.
5. Repeat steps 1-4 with jacks numbered 9-16.
6. If no problems have been noted, remove power and continue installation.
I/O Connections and Testing
• Determine the correct wiring conguration for your setup. It is a good idea to label the RCA cables as to the actual location
they either come from or go to (e.g. Input 1 - Cable Box, Input 2 - Music Server, Zone 1 - Kitchen, Zone - 2 Living Room etc.)
Be sure to use good quality RCA cables for optimal results.
• Connect the ADX power supply; the unit will immediately power on.
• Apply power to all sources and associated equipment. Use the front panel controls to verify audio signal integrity of sources
at each zone location.

8
Advanced Setup and Remote Control Options
Using the RS-232 Port.
System controllers and PCs can send all setup and control commands as well as receive feedback via the RS-232 serial port.
• Important: If a PC is connected directly to the ADX RS-232 port, use a standard serial cable.
• The baud rate is set to 9600 by default, but this may be changed using the Front Panel Menu screen “Serial”. The other
connectivity parameters are xed to 8 data bits, no parity, 1 stop bit, and no ow control.
• See the table and diagram below for the ADX serial port pinout.
This control method is capable of performing all commands (See Appendix A).
Ethernet
Serial commands can be issued using an Ethernet connection and a telnet program.
There are two LED indicators located next to the Ethernet port on the rear panel that will help in identifying connection
issues:
• Link - The Link LED is steadily lit if a connection is detected and ashes when activity is present.
• Speed - The Speed LED is off for 10 base T, and on for 100 base T.
Using the Ethernet Port
Use of a telnet client or terminal program on a Mac or PC allows commands to be sent through the Ethernet port on
the ADX. Connect a PC directly to the Ethernet port using a crossover cable, or alternatively use a standard Ethernet hub
or switch and a standard patch cable. Once connected to a PC or network, the ADX by default will attempt to obtain an IP
address automatically using DHCP. To use Static settings, see the detailed instructions on page 9.

DHCP
If DHCP is enabled on your network, simply connecting the ADX to the network with an existing DHCP server will enable it to
obtain all necessary information. DHCP is enabled on the ADX by default.
Static addressing connected directly to a PC
The ADX must be given an IP address which will not conict with the PC. Go to the network settings (which are found in
control panel -> network -> local connection properties of a PC running Windows XP).
Change the TCP/IP protocol properties, and set the IP address, gateway, and subnet mask, if they are not already set.
This can be arbitrarily done on a direct connection, but a good choice for the settings would be IP address of 192.168.0.1,
subnet mask of 255.255.255.0, and an empty default gateway. Once these values have been set, use serial commands to
set the network settings of the ADX-1616 in a similar manner, but use a different IP address than that of the computer (for
example, 192.168.0.2).
Static addressing on a network
The ADX must be set to the same settings as the PC except for the IP address, which must be one available on the network.
To determine this in Windows, use the DOS prompt (Start->Run->cmd) commands ipcong and ping. Ipcong will list the PC’s
settings, and ping will allow you to test addresses to make sure that nothing else on the network has that address. Enlist the
help of a network administrator if you are unfamiliar with setting up a network connection.
Once connectivity is established, a telnet program such as Hyper Terminal, Teraterm, PuTTY etc, must be used to connect
to the device. Enter the IP address of the ADX and leave the default port (23) to connect. Once connected, standard serial
commands (listed in Appendix A) can be issued in an identical manner to serial control.
Using a Comprehensive IR Control System
The ADX uses a three wire IR circuit. It is imperative that the correct polarity be maintained when connecting third party IR
equipment. The 3.5MM pinout is shown in the illustration below and the connecting block pinout is screen printed on the back
panel of the ADX. Patch the IR signal from your IR receiver directly to the IR input port on the rear panel using the connec-
tion method of your choice. Alternatively, you may place a stick-on emitter from your infrared system on the ADX front panel
receiver.
If the ADX IR codes are available from your remote control company, download and/or activate those les.
A CCF le containing ADX codes can be downloaded from the Audio Authority
website,
www.audioauthority.com/page/software.
Tips for Using Infrared Control
• If you are using standard hand-held IR remote controls, ensure correct operation
by avoiding sources of light pollution such as Plasma and LCD TVs, direct
sunlight, uorescent light, etc. Experiment with the physical placement of the IR
receiver to avoid interference.
• If a source of interference cannot be eliminated or avoided, use IR receivers that
block that type of interference, such as Plasma-proof or LCD-proof receivers.

Appendix C: Troubleshooting
Symptom Possible Cause
No power • Check for available AC power from the wall outlet.
• Check to make sure there is 18V available from the provided power supply. If not, remove
the power supply from the wall and reconnect.
No Audio • Check for proper operation of Source and Receiver.
• Ensure cabling between the ADX and third party equipment is good and connected properly.
• Ensure power is connected to the ADX.
• Check volume levels at receiver and in ADX controls.
No Ethernet Control • Refer to Page 8 and Appendix A for Ethernet Setup and Control. If problem persists, contact
your Installer or Network Administrator for assistance.
No RS232 Response • Make sure the Baud Rate matches between the ADX and the Serial Terminal program being used
to issue commands. ADX Default = 9600
• Make sure Flow Control is turned off.
• Check cable pinout for compatibility between ADX and control equipment.
No USB Response • Ensure the USB storage device you are using is USB 1.1 or USB 2.0 compliant.
• Some USB storage devices may not be compatible with the ADX. If your device meets the standard
requirements but will not function with the ADX, try using a different USB storage device.
No IR Response • Check the Front Panel for “Front Panel Lockout Activated” message.
• Ensure proper connection and operation of any external IR receiver.
