The Lance Design ADX-2400 series audio delay and distribution units are very powerful tools for distributing multiple channels of high-quality audio throughout a fixed facility or between mobile units, announce booths, and other location facilities. The ADX systems utilize the powerful Cobranet (tm) audio networking technology, developed by Cirrus Logic. Cobranet is a well-proven industry standard method for transmitting full-bandwidth, low-latency audio via standard Ethernet media. Numerous other manufacturers utilize the Cobranet technology, and the ADX-2400 systems are fully compatible with any Cobranet hardware from any manufacturer.
A single ADX unit provides 24 channels of transmission in each direction in a compact 1 RU frame, with the audio transmission occuring over standard low-cost CAT5 cable. In addition, by utilizing inexpensive off-the-shelf ethernet switches it's possible to replace large numbers of audio distribution amplifiers, and heavy and expensive multi-conductor cabling. The network provides the distribution. Fiber transmission is also possible, using standard ethernet media converters or switches with fiber uplinks. By using gigabit Ethernet, up to 800 channels of audio may be transmitted over a single fiber.
The audio transmitted on the Ethernet network is nothing like streaming audio over the Web. It's full-bandwith professional audio, uncompressed, and transmitted with very low latency and guaranteed delivery. The sample rate is 48KHz, and the resolution is 20 bit.
In addition to the transmission functionality, the ADX units provide individually-adjustable delay on each output; each ADX unit contains 48 channels of high-quality delay (24 on local outputs, 24 on network outputs), which can be adjusted as needed to compensate for video processing delays, hall acoustics or other requirements. The delay range is 0-680 milliseconds, or greater than 20 video frames (at 30 fps).
There are two versions of the ADX-2400. The ADX-2400N has balanced analog inputs and outputs, wired to industry-standard DB-25 female connectors. The pinout matches standard Tascam DA-88 or Protools format. The ADX-2400D has AES digital inputs and outputs, in the unbalanced 75-ohm BNC format. Audio placed on the network by one type of unit may be received by either type, providing format conversion in the process, if required.
Front panel VU meter and headphone jack provide convienent monitoring of all signals.
