Low-Pass Filter (Low-Pass Mode)
This mode is used to turn any zone output into a dedicated mono low-
pass output for a subwoofer. Additionally, a low-pass zone output can
be grouped with a full range zone output to create a single 2.1 audio
zone. IR and serial group commands (source, volume, and mute) can
then be used to control both outputs (low-pass and full range) together.
See page 11 for instructions on how to set up a zone group and page 18
for source, volume and mute group serial commands.
How to set up a low-pass zone output:
1. On the Source/Zone Naming page, select and name a zone you
wish to designate as a low-pass output. If you are grouping a low-
pass zone with a full-range zone, it is recommended to name your
zones in pairs for clarity. For example, if Zone 1 is labeled “Master BR”, Zone 2 should be labeled “Master BR Sub”, and
so on.
2. On the Zone Audio Controls page, select a zone for low-pass.
3. Select Lowpass from the DSP Mode dropdown menu.
4. Make any desired changes to the Crossover Frequency. Range of adjustment is 40Hz to 240Hz*.

volume level from the ADX (i.e.
volume level is adjusted through an external amplier or volume control), select the “Volume
Lock” setting. When an ADX zone is set to “Volume Lock”, it ignores all ADX volume
up/down commands (Serial, Telnet or IR) and remains at a xed full output level.
Balance
1. Select a zone.
2. Adjust left/right balance levels accordingly*.
ADX EQ Presets Page
The ADX includes 10 built-in “Global” EQ presets, which can be used by any zone. By default,
all 10 EQ presets are at and require adjustment for use. The ADX EQ Presets Page allows
you to name all 10 presets and adjust band settings for each.
Modify and Store Global EQ Presets
1. Select a ZQ preset.
2. Name the preset in the ADX Preset Name text box.

USING SERIAL AND ETHERNET (TELNET)
Follow the instructions for your Control4, RTI, URC, or other controller to connect to the ADX using the serial settings below,
and/or Ethernet settings accessible via the ADX front panel menu. All of the commands listed in Appendix A can be used via
telnet or serial connection.
• At idle, the ADX checks for received serial or telnet data every 200 ms. Once data has been received, it checks every 1 ms to
handle rapid groups of commands and macros. After 100 ms of inactivity, it returns to checking at intervals of 200 ms.
• The ADX telnet server allows two clients to be connected at one time. Each client connection has a time out of 15 minutes; if
a client crashes and does not close the connection properly (sending an EOF) that connection remains busy until it times out.
Connecting to the ADX 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.
• Communication Settings: baud rate is 9600 bps, 8 data bits, no parity, 1 stop bit, and no ow control.
• See the table and diagram below for the ADX serial port pinout.
Using a Computer via Ethernet
To use a PC or Mac with the ADX, use a telnet client or terminal program to send commands (listed in Appendix A) through
the Ethernet port on the ADX. Connect a computer 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 computer or network, the ADX by default
attempts to obtain an IP address automatically using DHCP. To use static settings, see the detailed instructions on page 17 or
serial commands on page 21.
There are two LED indicators located next to the Ethernet port Non the rear panel that help to
identify 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.

DHCP
DHCP is enabled on the ADX by default. If DHCP is enabled on your network, simply connecting the ADX to the network with
an existing DHCP server enables it to obtain all necessary information.
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
(page 21) to set the network settings of the ADX 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 not conict with anything else on
the network. To determine this in Windows, use the DOS prompt (Start->Run->cmd) commands ipcong and ping. Ipcong
lists the PC’s settings, and ping tests 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 a connection 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 an 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 connection method of your choice.
Alternatively, adhere an IR emitter from your infrared system onto the ADX front
panel IR sensor.
If the ADX IR codes are available from your remote control company, download
and/or activate those les. A CCF le containing the latest codes can be
downloaded from the Audio Authority website, www.audioauthority.com/page/ir.
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 sensor to
avoid interference.
• If a source of interference cannot be eliminated or avoided, use IR sensors that block that type of interference, such as
Plasma-proof or LCD-proof sensors.
In addition to basic IR commands, discrete IR commands are now available for download at www.audioauthority.com such as:
• Connecting a zone to a source
• Mute on/off and mute toggle a zone
• Volume up/down in a zone
• Balance left/right/center in a zone
• Bass up/down/at in a zone
• Treble up/down/at in a zone
• Connecting a group to a source
• Group volume up/down
• Group mute on/off/toggle
