[. . . ] A crossover cable is not compatible with the IF-AV/DM or Aviom equipment. The preceding diagram shows an IF-AV/DM card connected to an 8-port A-Net distributor. The A-16D Pro distributor shown allows up to eight simultaneous parallel A-Net connections. With this arrangement, power is also supplied to each A-16II personal mixer over the CAT-5e cable. About Pro16 A-Net A-Net is Aviom's proprietary high-speed data transmission protocol designed specifically to transport uncompressed high fidelity streaming audio in real time over inexpensive Cat-5e cabling. A-Net as implemented in Pro16 products transports sixteen channels of digital audio (44. 1kHz or 48kHz, 24-bit) from the IF-AV/DM card to each Personal Mixer or AN-16/o Output Module connected to the system. An unlimited number of Pro16 A-Net devices can be connected to a system. A-Net's proprietary design delivers ultra-low latency (less than 1 msec from analog input to analog output) in all configurations. CAUTION A-Net is based on the physical layer of Ethernet, which provides Pro16 A-Net a mature and robust base on which to build. However, Aviom products are not compatible with off-the-shelf computer products designed for Ethernet networks such as hubs, routers, and switches. Series connections The diagram above shows an IF-AV/DM card installed connected in series to a group of A-16II Personal Mixers. Any number of A-Net devices can be connected in this manner. Cables runs can be up to 500 feet, 150 meters long between devices. Each A-16II Personal Mixer should be individually powered. Cable lengths Your cable length performance will be affected by a number of factors including the quality of the cables used, and the number of devices such as cable couplers used or wall panel interconnections in use. To go longer than the maximum specified distance A-Net allows (500 feet, 150 meters), an A-Net Distributor product can be used as a signal repeater. Simply insert the A-16D or A-16D Pro into the A-Net stream at the 500-foot point and the A-Net signal will be refreshed. Another 500 feet (150 meters) of cable can then be added. This process can be repeated as many times as required to extend cables. In fact, any Pro16 A-Net device that has an A-Net out connector can be used as a signal repeater. Parallel connections Parallel connections avoid some of the pitfalls of a serially-connected system. Each A-Net device is directly connected to a data source instead of depending upon the previous user in a daisy chain for data delivery. 2 TASCAM IF-AV/DM Aviom Pro16 A-Net Interface Card NOTE Using the A-Net out connector of, e. g. a A-16II Personal Mixer to extend the signal does not supply power to the additional units, which must be powered individually. IF-AV/DM The IF-AV/DM is connected to one or more A-Net receivers. · xxx T meouts: i A problem was encountered. For long distance applications, fiber optic cable can be used to span distances up to 50 miles (80 km) with the use of devices called media converters. A media converter changes the Ethernet-based Pro16 A-Net signal to fiber optic at the source location and then back to Cat-5 at the destination. Several companies make fast Ethernet to fiber media converters that can be used with your IF-AV/DM and Aviom equipment. ª STEREO LINK Use the up and down arrows and then the ENTER button to toggle the state of the channel pairs that you wish to link or unlink. When linked, the display on the Personal Mixers will change to show a stereo spread control instead of a pan control for those two channels. The channel's volume will also be controlled as a pair. [. . . ] All connected Personal Mixers update immediately. The spread control When two Channels are linked, they no longer have separate pan controls on the Aviom Personal Mixer. With the Channel link comes a new feature, called Spread. The Spread control varies the stereo image of the two linked Channels from full stereo to mono. This allows you to position stereo sources in your mix by controlling the width of the stereo image. [. . . ]
