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.

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.

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 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.

ADX-120 Network (Dante) Input and Output Channels These are the signal names which will appear in the Dante Controller application. There are eight network inputs and eight network outputs. Network Outputs (Transmitted to the Network) MIC 1 - The headset mic (front XLR), after mute and talkback switching ...

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.

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.

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.

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.

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).
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.
