SELECTING OPERATING MODE With firmware versions 2.0 and later the ADX-2400N 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-2400N in this mode transmits three bundles of eight channels each, and receives three bundles of eight channels each.
LOW-LATENCY OPERATION IN NORMAL MODE Starting with Version 3.0 firmware, it is possible to operate the ADX-2400N in normal mode, but with low-latency transmission. Low-latency transmission reduces the path delay from one ADX-2400N to another ADX-2400N 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.
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.
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.

The transmitter is not putting any data on the network. Otherwise, it will indicate the number of receivers listening to this transmitter.
Status Item 09 – 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 ADX2400N-xx). This IP address and system name appear when using the Cobranet 'Discovery' application to report network node status.
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'.
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.

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 ADX2400 front panel. There are three catagories of configuration: 1. The ADX-2400 Menu Configuration This is where the remote devices are assigned to be Units A, B, C, and D.
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 ADX120 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.
Assigning the ADX120 / ADX140 to be Units A, B, C, or D The announce units must first be assigned to be devices A, B, C, or D in the ADX2400 menu. To do this, press the MENU button once, and select config items 1, 2, 3, and 4 respectively using the knob. When the desired item is selected, press the MENU SET button and select the appropriate System ID number for the ADX120 or ADX140 you want to assign. Pressing either SET or MENU will take you back to the item select mode.
ETHERNET NETWORK INFORMATION The Ethernet transmission uses the Cirrus Audio 'Cobranet' protocol, which is an industry standard. It is a professional, highly-reliable system which packs audio data into 'bundles' of 8 (or fewer) channels. The bundles are given numbers from 1 to 999. The first 255 are 'broadcast' bundles which can be received by any number of receivers, so long as the receiver is set to the same bundle number.
Setting Bundle Numbers (Does not apply in Announce Booth Mode) The 24 transmit and 24 receive audio channels in the ADX are divided into 8channel groups. These groups are assigned to network channels or 'bundles'. There are six bundles per ADX unit, three for receive and three for transmit. Each of these bundles can be assigned a three-digit number from 000 – 999. (Note that the Cobranet system allows numbers as high as 65000, but they are limited in the ADX2400 to 999).
Exceeding this bandwidth limit will cause dropouts in the audio, and in severe cases may cause other problems such as sync and control problems. An Ethernet switch or switches, which generally form the network, can partition the traffic so that bundles only go the receivers which are listening to them. Since each ADX frame only has three receivers, this can eliminate network traffic problems if each bundle is a unicast bundle (one transmitter to one receiver).
Cobranet 'Discovery' PC Application Cirrus Logic, the developers of Cobranet, make available on their website a nice PC application called 'Cobranet Discovery', or 'Disco'. It can be downloaded and installed on any PC running Windows XP. It allows the computer to be attached to the audio network and provides a variety of information about the attached network devices. Documentation is available on their website: www.cobranet.info, or at www.lancedesign.com.
Installation The ADX-2400N is designed to be installed in a standard 19" equipment rack. There is a cooling fan on the rear panel which draws air in through the sides of the cabinet and exhausts hot air through the rear panel. The unit should not be installed in such a way as to block the vents on the side panels, or air flow from the rear panel fan. The unit is designed to operate on 95-250 volts AC, 50 or 60 Hz.
Reliability Considerations Since on-air audio is often handled by the ADX systems, 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.
