Page 4: An Introduction To The Dns 8D
® multi-channel digital audio via standard Ethernet networks with near-zero latency and perfect synchronisation. The DNS 8D is the first DNS with a Dante interface in addition to its AES3 audio connections (DB25 using the AES59 pin-out). With fail-safe AES3 audio bypass implemented in the form of hardware relays that immediately connect the inputs to the outputs in the event of a power failure plus support for Dante’s redundant... -
Page 5: Safety Instructions
Mounting and ventilation You should place the DNS 8D on a flat, stable surface or mount it in a standard 19” equipment rack. Use the supplied rubber feet to avoid scratching the surface, or the rackmounting accessories, as appropriate. -
Page 6: Setting Up The Dns 8D
SETTING UP THE DNS 8D Unpack the DNS 8D carefully. Save the carton and all packing materials since you may need them to transport the unit in the future. In addition to the DNS 8D and its packaging, the box should contain the following:... - Page 7 Fail-safe bypass The DNS 8D offers AES3 fail-safe bypass as standard. In the event of a power failure the AES inputs become connected directly to the AES outputs by relays, bypassing the active electronics of the unit.

Page 8: Operation
OPERATION Power/Lock The DNS 8D switches on automatically when power is applied. This guarantees that it reboots after a power failure. Switch it off by pressing and holding the power/lock button for about three seconds. The current settings will be stored during shutdown. If the unit is not shut down correctly, settings may not be stored. - Page 9 THE SCREENS Main screen - Summary mode The main screen provides visual feedback regarding the current operation of the unit as well as displaying the menus and associated parameters. In normal use, the four boxes provide information regarding the operation of the DNS 8D: •...
- Page 10 Individual screens - Detail mode The first six displays (1 - 6, viewed from left to right) show the Attenuation and Bias information for a given channel or group on a band-by-band basis, with the lowest frequency band shown within the furthest left display, and the highest frequency band shown within the sixth display.

Page 11: In Use
Learn With Learn (S2) on for any channels or groups of channels, the DNS 8D continually identifies the power and spectral distribution of the noise present. When Learn is Off, the noise identification is frozen at the last determined values. If Learn is Off when the unit is switched off, the current noise measurement will be saved and recalled when the unit is next switched On. -

Groups Grouping channels together makes them adopt identical settings, and allows you to adjust them together. Group channels by clicking two encoders simultaneously or in quick succession. For example, pressing encoders 1 and 4 will group channels 1, 2, 3 and 4 together. Pressing them again removes the grouping. When channels are grouped, you can adjust their Attenuations and Biases using any of the grouped encoders. - Page 13 These allow you to step through the channels/groups. Tutorial If you wish to determine in more detail how the DNS 8D processes each channel, you should use Detail mode to adjust the Attenuations and Biases in each of its six control bands.

Page 14: Menus
Some menus provide options to move around on screen and to edit characters or values in specific locations. Status The status page reports the current audio and network status of the DNS 8D. No editing is possible on this page. Page 14... - Page 15 For further explanation of these values, please refer to your Dante documentation. Presets The DNS 8D contains 100 memory locations (“presets”) numbered 0 to 99. Each preset stores the process settings of all eight channels, including grouping when appropriate. If Learn is switched Off, the frozen noise measurement is also stored as part of the preset.
- Page 16 When Off, you may set these manually. Note for network administrators: The DNS 8D sends its serial number as its host name in DHCP requests. If your DHCP server registers host names in the domain name server, you can access your DNS 8D as dns-8-xxxxx.yourdomain.com instead of directly by its numeric IP address.
- Page 17 When configured correctly, the DNS 8D will respond to ICMP echo requests (pings) to its control Ethernet IP address Screensaver Select the length of time that passes between the last adjustment and the screen saver dimming the screens to prolong their lives. Options are 5, 30 or 180 minutes, or Off.

Page 18: Remote Control
To access it, connect the DNS 8D’s control port to your Ethernet network. It will attempt to obtain an IP address from the network using DHCP and then register its serial number as its hostname. Once this is complete, enter the unit’s address... -

SETTINGS You may set up the DNS 8D over the network using a standard web browser. Determine the address of your DNS 8D by inspecting the Status window, then launch your browser and type the following into the address bar… xxx.xxx.xxx.xxx/settings.html …where xxx.xxx.xxx.xxx is that address. -
