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. 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. Mixer control screen On both the DM-3200 and DM-4800, the IF-AV/DM presents a setup display screen as shown below. Navigate to the Digital page (LCD access button 2 with blue ALT LED lit), and then select the SLOT tab (labeled SLOT1-2 or SLOT 3-4 on the DM-4800) Use the 4 arrow keys to the right of the LCD screen to move the cursor over to the A-Net Card area. It may be on the left or the right hand side of the screen, depending on which slot the card is inserted into. Use the ENTER key to make changes. The JOG/DATA dial can also be used to move the cursor up and down. This display has the following: ªª STATUS This shows whether the IF-AV/DM card itself is working correctly and the state of the A-Net. CARD Status •• OK: The IF-AV/DM is running at full 16 channel count. •• Unsupported FS: The mixer is not running at 44.1 kHz or 48 kHz, so the IF-AV/DM will not pass audio. •• Not Responding: A problem was encountered during configuration. A-Net Status •• OK: The IF-AV/DM is connected to one or more A-Net receivers. •• xxx Timeouts: A problem was encountered. ªªSTEREO 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. Compatible A-Net devices that do not respond to stereo linking will not be affected by changes to the Stereo Link status. System clocking Master clock When configured with an IF-AV/DM, the mixer can have any clock source as long as it is 44.1 kHz or 48 kHz. The IF-AV/DM does not operate at the 2x rates of 88.2 kHz and 96 kHz, so when the mixer is running at these rates, the A-Net output from the IF-AV/DM will be silent, and the LCD screen will show "Unsupported FS" for the A-Net Status field. Varispeed pitch The DM-3200 and DM-4800 can run at non-standard Sample Rates when locked to an external clock. The IF-AV/DM will follow along up to the limits of the mixer's clock. Here are the supported pitch ranges. •• 44.1 kHz : -6.0% to +6.0% •• 48 kHz: -6.0% to +6.0% Outside of these ranges, the mixer will mute and report a clock error. DM-3200/4800 settings The IF-AV/DM appears to the Mixer just like any other optional I/O card except that it may have 16 channels of I/O instead of 8 depending on whether the card is inserted into slot 1 (or slot 3 for the DM-4800). Mixer outputs By default, the DM-3200/DM-4800 routes busses 1 - 16 to IF-AV/DM outputs 1-16. These routing settings can be changed in the OUTPUT SLOT tab of the DM-3200/DM-4800's ROUTING screen. 3 TASCAM IF-AV/DM
