DESCRIPTION
The ADX-120 Commentary Unit (announce box) is designed to provide an ‘all-in-
one’ facility for live broadcast announce booth requirements, with all audio and
control between the mobile unit and the booth being transported by standard
Ethernet, on either copper or fiber.
The ADX-120 is available in both Cobranet and Dante versions. There are several
differences in features and operation. This manual is for the Dante version.
There is also available an ADX-120B (in Dante format only). The "B" version is
identical to the standard ADX120 except that includes a third level control knob on
the front panel. This third knob controls the listen level of the AUX 1 spare input.
A single ADX-120 unit provides the following functions:
1) Two high-quality microphone channels; one on a front panel XLR for headset
use, and a second on a rear-panel XLR for a stand-up ‘stick’ mike, or an
effects mike. The second input can also be used as a balanced line-level
input. Phantom power is available for both microphone inputs.
2) A two-channel dry IFB for the announce headset. Volume controls are
provided on the top of the unit for each of these two channels.
3) A two-channel wet (RTS-Format) IFB for the stand-up position. This output
has enough DC current available to operate two IFB beltpacks. This output
may also be switched to a dry balanced output, selectable to either of the two
ifb channels. This is useful for a dry IFB beltpack, or an SA speaker or other
purpose. The audio quality is very high, so this path is usable for program
audio if required.
4) A two-channel wet (RTS-Format) TW intercom. There are two active hybrids
in the unit, one for each channel. The truck-end connections are four-wire,
and so this eliminates the need for external 4W to 2W converters. The DC
current available is sufficient to operate two BP325-type beltpacks. There
are noise gates on the TX side of the hybrids, so that any trans-hybrid
leakage is minimized on the truck (4W) end.
5) An illuminated “Mute” button and two talkback buttons are provided for the
announcer. The two talkback paths are available in the truck as either
discrete outputs or mixed.. The button illumination is provided by RGB leds,
and the on and off colors are selectable, allowing for color-coding of the
button functions for the announcer’s convienence.

Other features include:
1) Power provided by the ethernet connection. The ADX-120 adheres to the
802.3af POE specifications, but this standard does not allow sufficient power
for four RTS beltpacks. Lance Design has available a 1RU Ethernet switch
and dual power supply (ADX-8000) which provides robust power for up to
eight ADX-120s, with ample reserve for the full beltpack complement. In
addition, this supply contains redundant, load-sharing high-efficiency power
supplies with fault indication for maximum reliability.
2) The unit is very compact, and simple to implement. In a typical application, a
single CAT5E cable connects each announce box to a small enclosure which
contains the ethernet switch / power supply (ADX-8000), and perhaps one or
more ADX-140 XLR panels or other equipment.
The fiber link to the mobile unit or studio is typically gigabit fiber. An ADX-
120 typically requires on the order of 11 to 15 mb of bandwidth, so a single
gigabit link can support a large number of ADX-120s and/or ADX-140s.
3) The audio quality is very high. The microphone preamps are extremely low-
noise, transparent designs, and considered to be some of the industry’s best.
Preamp gain is remotely-controlled over a wide range.
All audio paths are of the highest quality with 24-bit resolution throughtout. All
signal switching, routing and gain control is performed in the digital domain in
a high-performance 32-bit dsp. Talkback, IFB and PL circuits are all full
bandwidth, program-quality channels, so all of these paths are extremely
clean, and provide excellent audio quality to the announcers’ headsets and
the PLs.
4) Dante networking provides complete flexibility in signal routing, with reliable
low-latency transmission. In addition many third-party manufacturers also
support Dante, and the ADX-series products are all fully-compatible.

System Overview
The ADX announce system consists of the following elements:
One or more ADX-2400 frames which serve as the 'head end' or truck end of
the system, and provide all inputs and and outputs for the truck or control
room, as well as remote control of connected ADX-120s and ADX-140s.
One or more ADX-120 Announce Boxes or ADX-140 Interface Frames which
function as the remote units in the booth or other remote location.
ADX-8000 Ethernet switch / power supply for the ADX-120 units. This unit
provides the power and network interface for the ADX-120 and ADX-140
remote devices.
Other network infrastructure as required, consisting of standard Ethernet
switches, fiber optic elements, media converters, fiber and copper
interconnects, etc.
Each ADX-2400 unit provides 24 receive channels and 24 transmit channels. These
channels may be used in any way desired by the user, and routing is controlled by
the Audinate "Dante Controller" application running on Windows or Mac. This
application may be obtained from the Audinate website:
https://www.audinate.com/products/software/dante-controller
Once the application is installed, connect the computer to the Dante network and run
the application. All of the Dante devices on the network should be visable, and can
be routed as desired. Routing configurations are stored in each unit, and overall
system configurations may be stored as files using Dante Controller.
The remote devices are identified by the ADX-2400s by a SYSTEM ID number,
which is set by a two-digit rotary switch on the remote device (rear panel of the ADX-
120, front panel of the ADX-140). Each device must be set to a unique system
ID (01-99).
This system ID number allows the ADX-2400 to identify and communicate with each
remote device (ADX-120 or ADX-140), and access the remote menu items. It is not
specifically related to the Dante device name. The Dante names may be changed to
anything desired by the users via the Dante Controller application.
The ADX-2400 allows remote control of all remote device setup functions from its
front panel. These include things like preamp gains, IFB configurations and button
colors, as well as return of several status items such as temperature, PL voltage and
current, etc.
The descriptions of the menu items later in this manual describe these remote
control functions in more detail.

The Mobile Unit End
ADX-2400 Front Panel
The ADX-120 Commentator Units typically connect via fiber to an ethernet switch in
the mobile unit, and via that path to an ADX-2400 Network Interface, which provides
the headend for the system. Other Dante devices such as mixing consoles may also
be connected to this switch.
The ADX-2400s provide a Dante interface to the mobile unit, as well as remote
control of the ADX-120s and ADX-140s in the field.
Each ADX-2400 provides 24 network receive channels and 24 network transmit
channels. When the ADX-2400 option dip switch section #3 is turned on, the ADX-
2400 is in the 'announce booth mode', which provides some mixing options on
network receive channels 9-16, and a PL matrix on network receive and transmit
channels 17-24. The delay function is also disabled.
Each output, whether a local output or a network output may have its source chosen
from the selections available when the SOURCE button is pressed. Note that this is
not Dante network routing, but selection of internal local sources (local input, net
receiver , tones, silence, perhaps mixers, etc.)
The channel 9-16 mixer options allow any or all of these channels to be mixed down
to one or more outputs. This may be useful for mixing talkback signals without using
an external mixer.
The PL Matrix functions somewhat like the familiar 'Thumbwheel' panels for two-wire
intercoms, in that it allows each pair of of TX/RX channels in the range 17-24 to be
assigned to a particular local (four-wire) channel. These selections are made by
selecting an output in the range NET 17 to NET 24 and pressing the SOURCE
button. The desired PL channel selection may then be made. This selection
automatically assigns both the talk (TX) and listen (RX) sides of the PL.
All outputs and levels may be reset to a standard configuration by pressing the
MENU button, selecting 'Recall Standard Config', and pressing the MENU SET
button.
Front panel metering and headphone monitoring is available for all outputs.
See the appropriate ADX-2400 manual for more detailed information.

Remote Control
Each remote device (ADX-120/140) has an internal menu which may be accessed
remotely via the ADX-2400.
These menus configure the hardware of the remote device itself, and are specific to
the particular model, i.e. the ADX-120 has different options from the ADX-140
because of differences in their hardware capabilities.
Microphone preamp gains for both mic preamps.
Selection of Headphone mode (stereo, mono, etc.)
Selection of mic or line input for the mic 2 input
Selection of phantom power for each mic
Selection of headphone volume range (to adjust for high or low headphone
impedence)
Selection of wet or dry mode and source for the rear-panel IFB 2 connector
Optional sidetone mixed to headset
Optional Aux inputs mixed to headset
Selection of button illumination color for the panel buttons
Selection of button mode; either momentary or 'smart' latching
Status reporting of PL and IFB currents and voltages, temperature, and
ethernet port status.
These remote menu settings are saved in the remote devices themselves, and
will remain associated with a particular device, even if it is moved or has its
system ID reassigned. These settings are not stored in the ADX-2400 at the
truck.
Status of many of the remote configuration items is displayed by LEDs on the
remote devices (rear panel on the ADX-120s, front panel on the ADX-140s).

10
Accessing Remote Menus from the ADX-2400
The configuration items for the ADX-120 and ADX-140 units are accessable from
the front panel of the ADX-2400.
To access these remote unit menus, double-click the MENU button on the
ADX2400. The display will say: SELECT REMOTE DEVICE. The MENU button will
be flashing to indicate that a remote device is being accessed.
The menu display will look similar to this:
Use the knob to select the desired remote device. The Device Name displayed to
the right of the ID number will be the Dante Name, as entered by the user via Dante
Controller. If there is no device name displayed to the right of the ID number, then
there is no active device at this ID.
When the desired device is selected, press MENU again. This will access the menu
of the remote device, and the menu might look like this (depending on the type of
device and the selected item):
The configuration and status items may be selected using the knob. Once the
desired item is selected, press the MENU SET button to allow changing that item's
setting. Settings are saved automatically after about 10 seconds of inactivity.
Press either MENU SET or MENU to go back to the item select mode.
When you're done, the easiest way out of any of the menu modes is to just press the
OUTPUT SELECT button. This will cancel all menu modes, and you won't have to
step backwards out of them.

ADX-120 Remote Menu Items
The ADX-120 menu items for firmware version 1.0 are listed below.
Config Item 01 – Mic 1 Gain (25-70dB)
This is the preamp gain for microphone input 1 (the front-panel headset input). It
would typically run around 35 to 45 dB for normal sports use with dynamic mics.
Config Item 02 – Mic 2 Gain (25-70dB)
Same as above for microphone input 2 (rear-panel XLR). When this input is in the
'Line In' mode, the gain is fixed, and Item 02 will indicate that the input is in line
mode.
Config Item 03 – Channel 2 Input (Mic or Line)
This selects either mic or line input mode for the rear-panel XLR input. When in Mic
mode, Item 02 sets preamp gain. When in Line mode, the gain is fixed through at
unity through the system. The nominal 0VU level is +4dBm. Line input mode is
indicated by a yellow LED on the rear panel.
Config Item 04 – Mic 1 Phantom (On / Off)
Turns on phantom power for Mic 1. Indicated by a green LED on the rear panel.
Config Item 05 – Mic 2 Phantom (On / Off)
Turns on phantom power for Mic 2. Indicated by a green LED on the rear panel.
Phantom power for Mic 2 will automatically be turned off when Line In mode is
selected.
Config Item 06 – IFB 1 Mode
Controls the signal routing for the IFB 1 output (front-panel headset). The selections
are as follows:
Normal 2 Ch - IFB1 is routed to one side , PGM1 is routed to the other side
IFB to Both - IFB1 is routed to both sides of stereo headphones
PGM to Both - PGM1 is routed to both sides of stereo headphones
MIX to Both - IFB1 and PGM1 are mixed and routed to both sides. Volume
knobs control the mix.
IFB to Mono - IFB1 is routed to the tip only of the 1/4" TRS jack
PGM to Mono - PGM1 is routed to the tip only
MIX to Mono - (see above)
Note: if you're using a mono headphone with a tip-sleeve plug select one of the
mono modes to avoid signal current from the other amplifier being shorted into
ground.

12
Config Item 07 – IFB 2 Mode
Configures the IFB 2 (rear-panel XLR) output. The selections are as follows:
Wet 2 Ch - Configured as 2-ch RTS-format. IFB2 on Ch1, PGM2 on Ch2.
Dry - IFB - Configured as dry balanced +4 output of IFB 2.
Dry - PGM - Configured as dry balanced +4 output of PGM 2.
Dry - Mic 1 - Configured as dry balanced +4 output of Mic 1 (headset Mic)*
*Note: The 'Dry-Mic 1' configuration uses the IFB2 connector as a direct line-level
output of the mic 1 preamp. The purpose of this is to make that signal available as a
redundant output to be fed to the truck via some other backup system.
Config Item 08 – Hdst Volume (Normal, High)
This controls the range of the signals feeding the headphones (front-panel jack). It
is really an adjustment for headphone impedence; e.g., it matches the range of the
volume control knobs to the impedence of the headphones. Normal should be used
unless high-impedence headphones cause the volume to be inadequate. The High
setting provides a 8dB increase in signal level.
Config Item 09 - Sidetone
This adds the local Mic 1 output to the headphones, either left, right, or both. This
might be useful if a mix-minus were being returned to the commentator instead of a
full mix.
Config Item 10 - Sidetone Level
Controls the level of the added sidetone
Config Item 11 - Aux Input 1
This allows the source routed to the Aux 1 network input to be added to the
headphone mix, either left, right, or both. The level is controlled by the third panel
knob on the ADX-120B, and controlled by menu item 13, 'Aux Level' on the ADX-120
Config Item 12 - Aux Input 2
This allows the source routed to the Aux 2 network input to be added to the
headphone mix, either left, right, or both. Level is controlled by menu item 13, 'Aux
Level' on both the ADX-120 and the ADX-120B versions.
Config Item 13 - Aux Level
Controls the level of both Aux 1 and Aux 2 sources in the headphone mix on the
ADX-120, and controls only the Aux 2 level on the ADX-120B.
Config Item 14 – Mute Off Clr
This sets the color of the illumination for the Mute button when it's in the off state
(not depressed).
Config Item 15 – Mute On Clr
This sets the color of the illumination for the Mute button when it's in the on state.
(depressed)

13
Config Item 16 –TB 1 Off Clr
Config Item 17 –TB 1 On Clr
Config Item 18 –TB 2 Off Clr
Config Item 19 –TB 2 On Clr
Illumination colors for on and off states of the Talkback buttons (as above).
Config Item 20 – Button Mode (Momentary / Latch Mute / Latch TB / Latch All)
Modes of Mute and Talkback buttons. Latching is 'smart' latching - tap to latch.
Config Item 21 – GPI Inputs (Disabled / Enabled)
Enables operation of the three GPI inputs on the rear panel (D9 connector). The
inputs are available for hand-held or footswitches, and operate the Mute, Talkback 1
and Talkback 2 functions respectively.
The remaining menu items are status items
Status Item 01 – PCB Temperature
This item displays internal temperature of the ADX-120 in degrees Centigrade.
Nominal operating temperature is in the 35 - 45 degree range.
Status Item 02 – PL Current
DC Current drawn by the external PL beltpacks. This should be less than 100
milliamps. The PL power supply will go into a shutdown condition if current is
greater than 140 ma.
Status Item 03 – PL Voltage
DC Voltage of PL power supply. Nominally 25 volts.
Status Item 04 – IFB Current
DC Current drawn by the external IFB beltpacks. This should be less than 100
milliamps. The IFB power supply will go into a shutdown condition if current is
greater than 140 ma.
Status Item 05 – IFB Voltage
DC Voltage of IFB power supply. Nominally 25 volts. Note that if a dry mode is
selected for IFB2, the power supply will be turned off and voltage will read zero.
Status Item 06 – Dflt Name (Default Name)
This name is the default Dante name if the device is reset to default configuration via
the Dante Controller. The six-digit hexidecimal number at the end of the name is a
portion of the MAC address, and is unique to each device.
Status Item 07 – Firmware Version
Display of the version number of the firmware installed in the ADX-120.

14
Resetting the ADX-120 Menu Variables to a Standard Configuration
The menu variables in the ADX-120 may be reset to a known standard configuration
by holding down any of the front-panel buttons during the boot-up period. (Hold one
of the buttons down and apply power. After the unit initializes the menus will be
reset).
The standard configuration is:
Both Phantoms Off Both Preamp Gains = 40dB
Channel 2 set for Mic Input IFB1 set to Normal 2 Channel mode
IFB2 set to Dry IFB mode Headset Volume set to Normal
Sidetone Off Aux Inputs Off
All Buttons = Green Button Mode = Momentary
GPI Disabled
Naming the ADX-120 (User-friendly Dante Name)
The Dante Name is a user-friendly name which appears in the Dante Controller
application. This name may be entered for each device using the Device View of the
Dante Controller application.
The first 15 characters will be displayed on the ADX-2400 when accessing the
remote device menus, and the full name will be displayed in Dante Controller.
Note that audio routing is defined based on these names. If you change
names, you may have to re-route some of your signal paths using the new
name. It's best to set all names first, then do routing.
To enter user-friendly names from Dante Controller, do the following steps:
1. Identify the unit that you wish to rename. From the ADX-2400 you can
access the remote device number for which the System ID switches are set
on the desired device. The current name will be displayed on the ADX-2400.
This device can then be selected in the Dante Controller application, and a
new name entered.
Alternatively, from Device View in Dante Controller, a device may be
identified by clicking on the 'eye' identify icon. This will cause all four of the
LEDs on RJ45 connectors of the device to blink at about a 1Hz rate.
(Note that you can enter Device View mode by pressing the Cntl-D shortcut,
selecting 'Device View' from the Device menu at the top of the screen, or by
simply double-clicking on one of the device names from the Routing or other
screen.)
2. From the Device View in Dante Controller, select the Device Config tab and
the desired device. You can then enter a new name in the box provided.

Reliability Considerations
Since the commentary microphones and communications are typically provided by
this system, reliability is of primary concern. The ADX-series products are designed
with highest-quality components and conservative ratings so as to be as reliable as
possible.
In addition, after manufacture, the ADX products undergo an extensive burn-in
process which includes power and thermal cycling to attempt to precipitate out any
early-life failures.
Even with these precautions failures are not impossible, and in addition there are
other components to the system such as Ethernet switches which must also be
considered in evaluating the overall reliability question.
Here are some thoughts on insuring a reliable on-air system:
Provide a spare announce box and headset. This practice has been going
on for decades with analog systems, and it's still a good idea. It protects
against failure of the ADX-120 and the headset.
Use the ADX-8000 to provide power for the ADX-120s. This unit contains
redundant power supplies and will provide highly-reliable power, even in the
event of the failure of one of the supplies.
Insure a reliable AC power source in the remote location for the ADX units
and for the Ethernet switch. If there is any question about the reliability of
the AC supply you might consider using a small UPS power supply to provide
battery backup. A small 500 watt unit intended for personal computer use
will provide an hour or more of operation in the event of power failure.
Use reliable Ethernet hardware such as switches, fiber SFPs, etc. Burn in
new switches for a few days before putting them on the air. Keep all
Ethernet cables and fiber in good condition.
Many switches have two or more fiber ports available. Use redundant fibers,
either by using link aggregation, or the ADX-8000's A/B mode.
Although the Dante audio data may share a network with other Ethernet
traffic, we suggest keeping the critical audio data on its own separate
network in order to avoid unexpected and unpredictable data loads and
possible bandwidth loss.
