SELECTING OPERATING MODE
The ADX-2400M can operate in two distinct modes:
The NORMAL mode is used for general-purpose transmission and distribution
applications. In this mode the units offer 24 channels of transmission in both directions,
using standard-latency Cobranet format transmission. The ADX-2400M in this mode
transmits three bundles of eight channels each, and receives three bundles of eight
channels each.
Bundle numbers are set manually from the front panel menus.
The DSPs in the unit are used for level control, source selection, and delay.
Transmission latency is approximately 7 milliseconds in each direction (standard mode -
see next page for low-latency information).
To select NORMAL mode, turn section 3 of the options dipswitch on the sub-
panel (behind the front panel) OFF and press the Reset button.
The ANNOUNCE BOOTH mode is selected when the ADX-2400 is used to provide the
'head end' or truck end of an ethernet-based announce booth system, using either ADX-
120 Announce Units, or ADX-140 XLR Interface Frames (or both) to provide a fully self-
contained announce booth system using copper or fiber ethernet as the transmission
medium.
In this mode, the ADX-2400 can support up to four ADX-120s or ADX-140s, in any
combination. The ADX-2400 transmits and receives four bundles of six channels each.
The transmission utilizes the Cobranet 'low-latency' mode, and results in a path latency
of 2.5 milliseconds.
The DSPs are reconfigured to provide routing matrices for IFB source selection, PGM
source selection, Talkback output configuration, and 4-wire port assignments for the PL
channels.
Bundle numbers are set automatically depending on the assigned system ID numbers
for the remote devices (ADX-120, ADX-140).
To select ANNOUNCE BOOTH mode, turn section 3 of the options dipswitch on
the sub-panel (behind the front panel) ON and press the Reset button.

LOW-LATENCY OPERATION IN NORMAL MODE
It is possible to operate the ADX-2400M in normal mode, but with low-latency
transmission. Low-latency transmission reduces the path delay from one ADX-2400M to
another ADX-2400M from approximately 7 milliseconds (standard mode) to
approximately 2.5 milliseconds (low-latency mode).
This mode is useful if using ADX-2400's for IFB returns or some other delay-critical
application.
Note that the ADX-2400s on both ends must operate in the same mode (either low-
latency or standard) for audio transmission to occur.
Low-latency operation requires that the ADX-2400M be equipped with a revision J or
later Cobranet interface module. If an earlier version module is installed, and fault
message will be displayed, and low-latency operation is not possible.
Also, note that low-latency operation puts more demands on the network performance.
Ethernet switches which operate comfortably with standard-latency operation my not be
satisfactory with low-latency operation. Gigabit ethernet switches are recommended to
insure satisfactory operation.
An 'LL' indicator will be present in the upper right corner of the display, indicating low-
latency operation is selected.
Note that low-latency operation is automatically selected when in Announce Booth
mode, and switch 4 will have no effect.
To configure the ADX-2400M for low-latency operation, turn on Options
Dipswitch #4, and press Reset.

QUICK OPERATION GUIDE - NORMAL MODE
To Select Output Channel (or Channels) to Adjust
Press ‘OUTPUT SELECT’ button, and turn knob until desired channel is selected.
Repeated presses of the 'OUTPUT SELECT' button will advance the selection to the
first channel of the next group of eight individual channels, or to the next group
selection. The order of the channel selection is as follows:
Madi Output 1 through 24 (Individual Outputs)
Madi Outputs 1-8 (Group)
Madi Outputs 9-16 (Group)
Madi Outputs 17-24 (Group)
All Madi Outputs (Group)
Net (Transmitted to Ethernet) Output 1 through 24 (Individual Outputs)
Net Outputs 1-8 (Group)
Net Outputs 9-16 (Group)
Net Outputs 17-24 (Group)
All Net Outputs (Group)
If the high madi channel range is selected in the menu, the madi channels will
be 33-56 instead of 1-24, and the display will change accordingly.
Note that if a group of outputs is selected, any setup adjustments (source, level,
delay) will be applied to all output channels within that group.
To Select Source (for current output or group of outputs)
Press 'SOURCE' button. It will light, and the currently-selected source for the
selected output will be displayed. The sources available for each output are as
follows, and can be selected by turning the knob.
SILENCE The output will be muted
MADI INPUT The output will be fed by the corresponding Madi input
NET INPUT The output will be fed by the corresponding network receiver
888HZ TONE The output will be fed by the internal 888 Hz tone generator
560 HZ TONE The output will be fed by the internal 560 Hz tone generator
You may enable a ‘stereo summing’ mode by selecting any of the following choices,
which follow the above sources in the menu list. In these modes, the selected
source will be combined with the selected source for the other channel in the
even/odd pair; e.g., channels 1 and 2, channels 3 and 4, etc. When a ‘something +
mix’ source is selected, the mixed signal is reduced by 6 dB.
SILENCE + MIX The output will be silence and the other channel mixed
MADI INPUT + MIX The Madi input mixed with the other channel of the pair
NET INPUT + MIX The network receiver mixed with the other channel of the pair
888HZ TONE + MIX 888Hz tone mixed with the other channel of the pair
560 HZ TONE +MIX 560Hz tone mixed with the other channel of the pair

To Adjust Level (for current output or group of outputs)
The output level can be adjusted in 0.25 dB increments. Maximum gain is +12 dB.
To adjust, press the 'LEVEL' button, and turn the knob.
To Adjust Delay (for current output or group of outputs)
The delay of each output can be independently adjusted from zero delay through
680 milliseconds, which corresponds to more than 20 frames at 30 frames/sec. The
delay is adjusted by first pressing the 'DELAY' button, then turning the knob to
adjust. Note that the displayed units (milliseconds or frames) is selected in the
menu.
To Adjust Headphone Volume
Press the 'HP VOLUME' button, and turn the knob. The bar graph display will show
the knob 'position'.
To Configure Menu Items
The system has several configuration items which may be set by using the menu
function. Press the 'MENU SELECT' button to enable the menu function. Turn the
knob to select the desired menu item, then press the 'MENU SET' button. Turning
the knob will now change the parameter for this item. When the desired selection is
made, you can exit the MENU SET mode by pressing any other button. (See
section on menu items below).
MENU ITEMS - NORMAL MODE
Item 01 – RX 1-8 Bundle (000-999)
Packet assignment for network receiver 1, which corresponds to audio channels (net
inputs) 1-8. This number should be set to match the bundle number of the
transmitter in another unit which is sending audio to this receiver. Note that bundle
000 is inactive (off). Bundles 001-255 are broadcast bundles, and should only be
used if one transmitter is sending to more than one receiver. Bundles 256-999 are
unicast bundles, and should be used for normal point-to-point, one transmitter/one
receiver operation.
Item 02 – RX 9-16 Bundle (000-999)
Packet assignment for network receiver 2, which corresponds to audio channels (net
inputs) 9-16.
Item 03 – RX 17-24 Bundle (000-999)
Packet assignment for network receiver 3, which corresponds to audio channels (net
inputs) 17-24.
8
Item 04 – TX 1-8 Bundle (000-999)
Packet assignment for network transmitter 1, which corresponds to audio outputs
NET 01 – NET 08.
Item 05 – TX 9-16 Bundle (000-999)
Packet assignment for network transmitter 2, which corresponds to audio outputs
NET 09-NET 16.
Item 06 – TX 17-24 Bundle (000-999)
Packet assignment for network transmitter 3, which corresponds to audio outputs
NET 17 – NET 24.
Item 07 – Conductor Priority (Low – Normal – High)
This item determines the priority of this unit to operate as the 'sync generator' for the
Ethernet audio network. It should normally be set to 'Normal' unless you specifically
want this unit to be the conductor, in which case it could be set to high. If set to
high, this unit will be the conductor unless another is also set high. In the case
where more than one unit has equal priority, the first unit active will assume the
conductor role. This selection isn't too important, since the network will quickly re-
negotiate a new conductor if the current conductor were to fail or be turned off.
Item 08 – Delay Units (Milliseconds – Frames (30) – Frames (25))
This item selects the units used to display the delay values. It only affects the
display, and if set to Frames, saves the user having to do the arithmetic in his head.
It assumes 33 milliseconds for 30 Frames/sec, and 40 milliseconds for 25
Frames/sec.
Item 09 - Madi Channel Range (1-24, 33-56)
This item selects the madi channels which will be seen as inputs to the ADX-2400M,
and the madi channels which will be output by the ADX-2400M. All other madi
channels in the input stream will be passed through the unit to the output stream
unaltered. Two ADX-2400Ms may be connected in series to use 48 madi channels.
Item 10 - Madi Input (Coax, Optical)
Selects which physical madi input will be enabled. Both optical and coax outputs are
always active regardless of this menu setting.
9
Item 11 - GPI Mode = (Off, Master)
For future or special application use. Should be set to 'Off' normally.
Item 12 - GPI 1/3 Device ID = (00-99)
Item 13 - GPI 2/4 Device ID = (00-99)
For future or special application use. Should be set to 'Off' normally.
Item 14 - Save To User Config 1
Item 15 - Save To User Config 2
Item 16 - Save To User Config 3
There are three user setup files, and these three menu items allow the current
configuration to be saved to these user config files. To save configuration settings,
select the appropriate item number and press 'MENU SET'. The configuration will
be saved to the selected file.
Note that 20 seconds after any configuration change, the current settings are
automatically saved to a default configuration, which will be automatically loaded at
power-up. This is separate from the User Configuration files above.
Item 17 - Recall User Config 1
Item 18 - Recall User Config 2
Item 19 - Recall User Config 3
Selecting one of these three items and pressing 'MENU SET' will cause the settings
previously saved in the selected User Config file to be recalled.
Item 20 - Recall Standard Config
Pressing the 'MENU SET' button will recall a 'standard configuration'. All levels will
be set to unity, all delays will be set to zero, all local outputs will have their sources
set to NET, and all network outputs will have their sources set to MADI. All bundle
numbers will be set to 000.
The following items are STATUS items, and are only to display status
information. They may not be directly changed by the user.
Status Item 01 – NET RX 1 Status (Active or Idle)
Displays ACTIVE status if data is being received by network receiver 1. This
receiver corresponds to net inputs 1-8. Note that the data could be silence; an
active receiver doesn’t necessarily mean that there is audio present.
10
Status Item 02 – NET RX 2 Status (Active or Idle)
Same for receiver 2, which corresponds to net inputs 9-16.
Status Item 03 – NET RX 3 Status (Active or Idle)
Same for receiver 3, which corresponds to net inputs 17-24.
Status Item 04 – NET TX 1 Status (Idle or Number of Receivers)
If this transmitter is turned off (bundle = 000), or if it is set to a unicast bundle
(bundle = 256-999) with no corresponding receiver present, this status item will
indicate IDLE status. The transmitter is not putting any data on the network.
Otherwise, it will indicate the number of receivers listening to this transmitter. The
network only counts receivers up to four, so if there are more than three receivers
present, the status item will report “>3 Rcvrs”.
Note that unless the status is IDLE, the transmitter is putting data on the network. If
assigned as a broadcast bundle (001-255), the status could be “ 0 Rcvrs “, if no
receivers were listening to this bundle number. The data is still present on the
network.
Net TX 1 corresponds to net outputs 1-8.
Status Item 05 – NET TX 2 Status (Idle or Number of Receivers)
Same as above for net outputs 9-16.
Status Item 06 – NET TX 3 Status (Idle or Number of Receivers)
Same as above for net outputs 17-24.
Status Item 07 – Conductor Status (Another Unit or This Unit)
Indicates if the network conductor ('sync generator') is this unit or not.
Status Item 08 – Ext AES Ref Status (None or OK)
Indicates status of the external (AES) reference signal. External reference must be
applied for proper operation of the ADX-2400M.
11
Status Item 09 – Madi Input Status (None or OK)
Indicates the status of the selected Madi input (coax or optical).
Status Item 10 – PCB Temperature ( degrees Celsius)
Indicates temperature of sensors on main PCB. Normal temperature is in the 40-46
degree range. A high temperature indication might indicate blocked vents or a high
ambient temperature, and will cause a fault message to be displayed if the
temperature exceeds 55 degrees C.
Status Item 11 – System ID (00-99)
Displays two-digit system (frame) ID, as determined by the rotary switches on the
front edge of the pcb, behind the front panel. These two digits are used as the last
octet of the network IP address (192.168.100.xx), and the last part of the Cobranet
system name (Lance ADX2400M-xx). This IP address and system name appear
when using the Cobranet 'Discovery' application to report network node status.
Status Item 12 – Firmware Version
Displays the version of the installed firmware.
12
System Configuration In Normal Mode
The ADX-2400 is designed to provide delay, level control and distribution for effects
or commentary audio. The system can be used for stand-alone delay of 24 audio
channels, or can be used to transmit and receive audio signals via a standard
Ethernet data network (24 transmit and 24 receive channels simultaneously), or the
combination of both functions.
The system is 'output oriented'. It can be thought of as having 48 outputs: 24 madi
channel outputs (on the rear panel), and 24 'network' outputs which are sent to the
Ethernet network. Each of these 48 outputs can be set up as follows:
SELECT SOURCE:
SILENCE, MADI INPUT, NETWORK INPUT, TONE1 (888HZ), or TONE2 (560Hz),
(or the one of the above sources mixed with the source from the other channel of the
even-odd pair, for stereo summing)
ADJUST LEVEL:
OFF to +12DB in 0.25DB steps
ADJUST DELAY:
0 milliseconds to 680 milliseconds (20 frames in 30fps), in 1 millisecond steps
The configuration of each output is independent, although you can select groups or
all to save setup time if you are setting them all to be the same.
The unit should also be thought of as having 48 inputs: 24 madi channel inputs on
the back panel, and 24 inputs from the network receivers.
Application Examples:
For stand-alone delay, all outputs would be set to 'local input', and level and delay
adjusted as desired. The network tx/rx would not be used.
For transmitting effects to another truck, and inserting delay in the path: The network
outputs would be set to 'madi l inputs', routing the analog audio inputs to the network
transmitters. Delay and level adjustment could be done as desired. The madi
outputs could also be set to 'madi inputs', providing an independent local delay.
Alternatively, the madi outputs could be set to 'network inputs', and these used as
network receivers for audio coming back from the network.
Distribution of effects or other audio to multiple trucks could be accomplished by
transmitting the audio using broadcast bundles, and receiving at each point of use.
Delay and levels could all be adjusted independently at the receivers, or globally at
the network transmitters.
All network receivers include SRCs, so all madi syncronization is local and
independent.
13
Saving and Recalling Configurations
The menu settings and the source, level, and delay settings are stored automatically
after 20 seconds of panel inactivity in a 'default' flash memory. This is the memory
which is restored automatically when the unit is first powered up.
You may also save configurations in three user memories. Select the desired
memory by selecting Menu Item 09-11. When the 'MENU SET' button is pressed,
the current configuration will be saved to the selected user memory.
To recall one of these user memories, select the desired memory by chosing menu
item 12-14. When the 'MENU SET' button is pressed, all config data saved in that
user memory will be recalled and immediately applied to the audio hardware.
Factory default or 'standard' configuration may be recalled by selecting menu item
15 and pressing 'MENU SET'. It may also be recalled on power up or reset by
turning on options dipswitch section 1.
The factory default sets all levels to unity, all delays to zero, local output sources to
net inputs, and net outputs to local inputs. All bundle numbers are set to zero.
Dipswitch functions (Ver 1.0 firmware)
There is an Options Dipswitch located behind the front panel, accessible by
removing the thumbscrews on either side of the front panel.
Section 1 - Causes factory defaults to be loaded at power-up. Normally OFF.
Section 2 - Unused
Section 3 - Puts ADX2400M into 'Announce Booth Mode' when ON.
Section 4 - Selects Low-Latency operation in Normal Mode when ON.
Section 5 - Selects older remote control protocol for use with early ADX120/140s.
Section 6 - Locks USER CONFIG 3 (inhibits saves to this config memory)
Section 7 - Locks Channel Setups (level, source, delay) when ON.
Section 8 - Locks Menu Selections when ON.

QUICK OPERATION GUIDE - ANNOUNCE BOOTH MODE
Selecting Output Channels and Assigning Sources
Press ‘OUTPUT SELECT’ button, and turn knob until desired channel is selected.
Repeated presses of the 'OUTPUT SELECT' button will advance the selection to the
first channel of the next group of eight individual channels. The order of the channel
selection is as follows:
Madi Output Channels 1 to 8 - Microphone Outputs (A1, A2, B1, B2, etc.)
Madi Output Channels 9 to 16 - Talkback Outputs*
Madi Output Channels 17 to 24 - 4-Wire PL Port Outputs
Net Outputs 1 to 8 - Selected IFB Feeds to Remote Units**
Net Outputs 9 to 16 - Selected PGM Feeds to Remote Units***
Net Outputs 17 to 24 - Assigned PLs to Remote Units****
* Any of the 8 talkback outputs may be fed by any individual talkback buttons on the
remote devices (or inputs 3 and 4 of the ADX-140), or various mixed combinations.
Silence or tones may also be selected. These selections are made by selecting the
desired output and pressing the 'SOURCE' button, then selecting the source with the
knob.
** The IFB feeds going out on the network to the remote units may be fed from any
of the 8 physical IFB inputs. The selections are made using the 'SOURCE' button,
as above. Any physical input may feed more than one IFB.
*** The PGM (Non-Interrupt) feeds going out on the network to the remote units may
be fed from any of the 8 physical PGM inputs. The selections are made using the
'SOURCE' button, as above. Any physical input may feed more than one PGM.
**** Any of the PL channels at the remote devices may be assigned to any of the 4-
wire ports on the back panel of the ADX-2400 by selecting Net Outputs 17 to 24,
then pressing 'SOURCE'. The assignments will be made automatically for both 4-
wire directions. (That's why there is no source assignment available for madi
outputs 17-24). The internal 4-wire matrix takes care of all necessary mix-minus
generation for the PLs automatically, so any remote device PLs assigned to the
same 4-wire port will be able to talk to each other. This is similar to the 'party-line'
function in the Telex Adam system, but it happens automatically.
The VU Meter and Headphone Jack, and the rear panel 'Monitor Output' XLR will
follow the output selection.
To Adjust Level (for current output)
The output level can be adjusted in 0.25 dB increments. Maximum gain is +12 dB.
To adjust, press the 'LEVEL' button, and turn the knob.
We suggest that output levels only be adjusted in special circumstances. In most
cases the levels should all be left in the Unity (0.00dB) settings.

System Configuraton In Announce Booth Mode
Configuration of the system takes place both in the ADX-2400 and in the remote
devices (ADX-120/140) themselves. This configuration is all done from the ADX-
2400 front panel.
There are three catagories of configuration:
1. The ADX-2400 Menu Configuration
This is where the remote devices are assigned to be Devices A, B, C, and D.
The other items are to configure the madi interface, GPIs, saving and
recalling the configurations to/ from user memory files, and status displays.
2. The ADX-2400 Channel Setup
This is where 'truck-end' routing assignments are made for the talkback
outputs, IFB and Program paths, and PL ports. These assignments are
made using the OUTPUT SELECT and SOURCE buttons on the ADX-2400.
The LEVEL button also is available to control output levels to both the rear-
panel outputs and the outputs sent to the network and thus to the remote
devices. The DELAY function is not available in announce booth mode.
3. The Remote Device menus
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.
These menus configure such things as preamp gain, phantom power, IFB
output configurations, headset impedence (level), button color, etc.
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).

Setting System ID Switches
The System ID switches on each unit allow the system to distinguish one unit from
another. Cobranet bundle numbers and Ethernet IP addresses are automatically
determined based on the System ID Switches.
The System ID switches are two-digit rotary switches on the rear panel of the ADX-
120 and on the front panel of the ADX-140. The ADX-2400 also has System ID
switches, which are behind the removeable front panel, on the PCB sub-panel.
The range for the switches is from 01 through 99 (00 is not a valid ID). No two
devices may have the same ID number.
Compatibility: ADX-2400Ms with version 1.0 or later firmware may be used with
earlier ADX-120s or ADX-140s by turning on Dipswitch section 5 on the 2400, and
using IDs for all devices with the first (tens) digit = 0. This is provided as an
emergency or interim operating mode. All remote devices should be upgraded to
version 5.x as soon as practical.
The System ID settings for the ADX-120/140 units become the reference for the
physical unit, and will be used in assigning those units to be A, B, C, and D
designations in the ADX-2400 menus (see next page).
