  • Page 4 SELECTING OPERATING MODE With firmware versions 5.1 and later the ADX-2400D 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.
  • Page 5 LOW-LATENCY OPERATION IN NORMAL MODE Starting with Version 5.1 firmware, it is possible to operate the ADX-2400D in normal mode, but with low-latency transmission. Low-latency transmission reduces the path delay from one ADX-2400D to another ADX-2400D from approximately 7 milliseconds (standard mode) to approximately 2.8 milliseconds (low-latency mode).

  • Page 6: Quick Operation Guide

    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.

  • Page 10 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.
  • Page 11 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 ADX2400D-xx).
  • Page 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.

  • Page 13: Saving And Recalling Configurations

    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.

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: Local Outputs 1 to 8 - Microphone Outputs (A1, A2, B1, B2, etc.) Local Outputs 9 to 16 - Talkback Outputs*...

  • Page 19 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.
  • Page 20 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.
  • Page 21 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.
  • Page 22 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.

  • Page 23: Designing The Network [Important Information]

    Setting Bundle Numbers (Does not apply in Announce Booth Mode) The 24 transmit and 24 receive audio channels in the ADX are divided into 8- channel 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 –...
  • Page 24  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).
  • Page 25 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.

  • Page 26: Installation

    There are no restrictions on the timing or locking of any of the 12 input signals. They will be syncronized in the unit to the network clock. All AES audio into the ADX-2400D should have emphasis turned off, as emphasis is not supported internally. The output channel status bits will indicate NO EMPHASIS.
  • Page 27 Redundant switches and parallel networks may be used. ADX-120s and ADX-140s with version 5.0 or later firmware include a sophisticated method of selecting the active ethernet connection based on both link status and the presence of audio packets.
