AN INTRODUCTION TO THE DNS 8D The CEDAR DNS 8D has been designed specifically for broadcast and live sound. With eight channels of noise suppression, it hosts a new algorithm that marries the best of the DNS 8D and the DNS 2 dialogue noise suppressors. With its slick user-interface...
SAFETY INSTRUCTIONS Read these instructions, and follow them. Water and moisture The DNS 8D must not be exposed to rain or moisture. Furthermore, if it is brought directly from a cold environment into a warm one, moisture may condense inside it. This, in itself, will not cause damage, but may cause electrical shorting.
AC input and the unit will continue to operate on DC power without shutting down or restarting. AES3 Connect the DNS 8D to your other audio devices using the DB25 connector wired according to AES59 - also known as the ‘Tascam pinout’. A suitable cable is available from CEDAR as an optional accessory. Page 6...

Channels AES/EBU pin-out for the Cold DB25 connector 1 & 2 3 & 4 5 & 6 7 & 8 1 & 2 3 & 4 5 & 6 7 & 8 View from rear of unit Unused:13 The clock is derived only from channels 1 & 2 so you must use this connection first; use of the other channel pairs is optional.
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.

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.
IN USE DNS On/Off Use S1 to switch processing on or off for the selected channel or group. Use SHIFT-S1 to switch processing on or off globally. 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.
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.

In the example above, 48kHz audio is being received via the Dante interface. The page is also reporting the unit’s MAC and IP addresses. Notes about the Dante fields: Dante is running in redundant mode Dante is running in switched mode DHCP On (server dynamically assigns an IP address and other network configuration parameters) DHCP Off (static IP address)

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. Brightness Select the screen brightness.
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.
PRESET MANAGER You may save and reload complete banks of presets 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/presetbackup.html …where xxx.xxx.xxx.xxx is that address.
Click on Browse and select the new firmware file, which will have been downloaded from the web or sent to you directly by CEDAR Audio Ltd. When the upload is complete, the DNS 8D’s front panel will instruct you to power cycle the unit.
