For systems larger than 32 channels, Aviom offers the AN-16SBR System Bridge as an option. The System Bridge allows up to four A-Net streams to be combined into a single Cat-5e cable for distribution over long distances. A 32-channel system is comprised of two pair of Pro16 Series I/O units, each providing a 16-channel data stream. (Remember that two AV-M8 units cascaded via the ADAT link create a single Pro16 A-Net stream.) Since the Pro16 system is modular, you can connect the Pro16 Series units as needed, making any of the configurations mentioned previously available at any time. Simply move and re-patch the units. A-Net Expansion In a 32-channel system, the A-Net Expansion port is used to allow two A-Net data streams to travel down one cable. • When creating a network with two pair of Pro16 Series units, one A-Net Expansion port will be connected to an A-Net In port while the other A-Net Expansion port will be connected to an A-Net Out port. • The A-Net Out ports on the Pro16 output modules should be empty when only four Pro16 Series units are being used to create a network. These ports are then available for adding audio splits with additional Pro16 output modules, or for connecting to a Personal Mixer product such as the A-16II or A-16R. • The cable connecting the two halves of the network (carrying 32 channels of audio) should be connected to one A-Net In port and one A-Net Out port. • Do not connect Cat-5e cables carrying expanded system data (more than 16 channels) to an A-Net Distributor or Personal Mixer product. • The maximum cable length specification of 500 feet (150 meters) applies to the length between an A-Net In port and an A-Net Out port. Cables used to connect devices via the A-Net Expansion ports must fall within this maximum distance. • An A-Net Expansion port is never connected to another A-Net Expansion port. • The A-Net Main Out on the AN-16/i-M Mic Input Module is the only A-Net port that works with the Expansion port. The A-Net Aux output carries only local data. 32-Channel Examples In the following examples, any Pro16 input module can be used. This includes the AV-M8, Y1 console interface card (for Yamaha products), D-16c console interface card (for DiGiCo products), AN-16/i, or the AN-16/i-M. Only one device is shown in the illustrations. They are referred to generically as “Pro16 input modules.” A pair of AV-M8 units cascaded via the ADAT link are shown in the diagram as a single input module. 32 Channels Send by Zero Channels Return The 32 x 0 configuration has 32 audio inputs on one side of the audio network and 32 audio outputs on the other side. With this configuration, up to 32 analog audio (mic- or line-level) signals are connected as inputs to two Pro16 input modules. One input module contains channels 1-16, while the other has channels 17-32. Audio channels 1-16 Channels 1-16 In Channels 1-16 Out Channels 17-32 In Channels 17-32 Out Pro16 Output A-Net Expansion Pro16 Input Pro16 Output Pro16 Input Audio channels 17-32 A-Net Two Pro16 input modules configured as 32 x 0 Two Pro16 output devices are connected on the receive side of the audio network. In the diagram, any Pro16 output device can be used. This includes A-16II and A-16R Personal Mixers, as well as AN-16/o and AV-P2 output modules. To configure a 32 x 0 system: 1. Connect the first 16 mic- or line-level audio sources to inputs 1-16 on the first Pro16 input module. 2. Connect the second group of 16 audio sources to inputs 1-16 on the second Pro16 input module. 3. Connect a Cat-5e cable from the A-Net out port on the first input module to the A-Net expANsioN port on the second input module. 4. Connect a cable from the A-Net out port on the second Pro16 Series input module and run it to the destination where the Pro16 output modules are located. Plug it into the A-Net iN port on the first output module. 5. Connect a Cat-5e cable from the A-Net expANsioN port on the first output module to A-Net iN on the second output module. 6. Patch the audio outputs from the two output modules into the desired destinations. Remember that the maximum cable length between A-Net devices is 500 feet (150 meters). Always use Cat-5e UTP cable. The diagram that follows shows a pair of 16-channel Pro16 input modules used for audio input channels 1-16 and 17-32, connected to a pair of output modules. 26 27 Channels 1-16 Channels 17-32 EXPANSION OUT EXPANSION OUT To configure a 16 x 16 system: Set up one input module (AV-M8, pair of AV-M8s, Y1 card, AN-16/i or AN-16/i-M) and one output module on each side of the network. Connect 16 mic- or line-level audio sources to inputs 1-16 on the first Pro16 Series input module. Connect a Cat-5e cable from the A-Net Out port on the first input module to the A-Net Expan sion port on the first output module. Plug a Cat-5e cable into the A-Net In port on the first output module. This cable will be used to span up to 500 feet/150 meters between the two sides of the network. Connect the cable from the A...
