Download and check the DNS 2 manual before raising a support request.
The current DNS 2 firmware is v1.4.
Press and hold the SETUP button for about two seconds. The firmware version will be displayed on Channel 2's LCD.
If your DNS 2 hosts a superseded version of the firmware, download the latest version and update your unit as follows:
An 80Hz, -18dB/oct high pass filter is available across all inputs. To toggle this on/off for either channel, press SETUP followed by the appropriate LEARN button. An icon on the selected channel’s screen will show whether the filter is active or not.
No. The AES input receives what you send it from elsewhere. The LEDs flash red when the signal level approaches 0dB, but this does not imply that clipping is occurring. The bands for the LEDs are:
The two channels on the DNS 2 can operate in three different modes. Cycle through these by pressing both encoders simultaneously.
Unlinked: The two channels operate independently. This mode is useful for processing two separate sources.
Linked: The audio channels are independent, but their control settings are linked. This mode is suitable for stereo signals. (When using analog inputs, the input gains are linked in this way only if both are set to MIC or both are set to LINE. If one input is set to MIC and the other to LINE, the input gains are not linked.)
Mono split: The audio presented to the Channel 1 input is split and sent to both channels. The Channel 2 input is not used in this mode. The channels have independent controls, so this allows a single signal to be processed in two different ways, or (by switching off the processing of one channel) for one output to carry processed audio and the other to carry unprocessed audio.
The input selection and link mode are indicated at the bottom of the Channel displays. Linked mode is indicated by an ‘=’ symbol, and mono split mode is indicated by an ‘>’ symbol. The input selection is indicated by M/L/D for microphone, line or digital respectively, followed by a 1 or 2 to indicate the input channel number. Hence, in mono split mode both screens show channel 1.
The DNS 2’s current settings are stored every time the buttons and screens go dim, which happens a few seconds after the user stops adjusting the controls. On v1.4 and later, the settings are also stored when the unit is powered down using the power button. These settings are recalled when the DNS 2 is next turned on.
If it appears that your unit is not storing the settings, its firmware should be updated to v1.4. (See above.)
The DNS 2 can be used in the same way as a DNS 8 Live by following these steps:

No. The hardware is completely different and the algorithms in the DNS 8D are a generation further advanced from those in the DNS 8 Live.
WRONG. The LEARN function is an advanced machine learning algorithm that constantly monitors the amount of noise present in the input signal, even when there is wanted signal present. Switching it on and off to create a noise fingerprint will degrade the DNS 8D's performance because the noise estimate won't be accurate at any future moment. In all but the rarest cases, you should leave LEARN switched permanently On.
The closer to the microphones that you can place the DNS 8D in the signal chain, the more effective it will be. In particular, try to avoid placing the DNS 8D after any form of dynamics processing or auto-mixing. These processes cause the noise floor to change rapidly and significantly, making it much harder for the LEARN function to track the genuine noise. Performance will always be improved by moving your compressors from before the DNS 8D to after it.
You can obtain very similar results, but not by using the same parameter values. The noise detection in the DNS 8D is more accurate than that in the DNS 8 Live, so you can use lower Attenuation values on the newer device to obtain equivalent amounts of noise reduction. If you feel that a DNS 8D is over-processing or suppressing high frequencies when compared with a DNS 8 Live, the chances are that you have set the Attenuation to the same value on each. Reduce the Attenuation on the DNS 8D to the point that the amount of noise removed is the same. To fine-tune the response, you can use the Bias parameter to increase or decrease the 'air' or 'atmos' in the output. If you wish to go even further, Detail mode will allow you to do this on a per-band basis for each channel.
The Bias - as the name suggests - biases the algorithm toward detecting more or less noise in the input signal. You can raise the Bias to increase the amount of noise detected. This will allow the DNS 8D to remove more noise, but it may also lead to compression of the wanted audio and make the signal sound slightly dry or gated. You can lower the Bias to decrease the amount of noise detected. This will allow the process to retain more ‘atmos’, but may allow noise to leak back into the output signal. In most cases, the optimum value for the Bias is zero.
• Learn and Bias determine what is detected as noise. • Attenuation determines how much of the detected noise is suppressed.
Further information is available in the DNS 8D manual.
To activate the reset function hold down the Power/Lock and S1 buttons while switching on power from the mains supply. This will erase all memories (firmware versions 1.0 and 1.1 only), and reset everything except Dante-related parameters to their factory defaults. Use Dante Controller to change Dante settings.
Note: A 'soft' power-up from the Power/Lock button will not reset the unit.
The current DNS 8D firmware is v1.5
If you your unit hosts a superseded version, download the latest version to update your unit.
You can update the DNS 8D firmware over a network using a standard web browser as follows:
Are you switching it off using a mains power switch at the wall or on some sort of power distribution system? You must follow the 'soft' power down procedure on the DNS 8D itself to store the current configuration.
No. The systems are very different and the DNS 8D cannot host the DNS 8 Live firmware.
Download and check the DNS 8 Live manual before raising a support request.
The current release firmware for the DNS 8 Live is v1.2.1. If your unit hosts a version before this, please download the latest version and update your unit from here. Earlier versions may be upgraded over a network using a standard web browser as follows:
There is no downloadable remote control software for the DNS 8 Live; it is incorporated in the unit in the form of an internal web page. You can connect to this using any suitable browser.
The current settings are stored when the unit is powered down correctly by pressing and holding the POWER button for five seconds. These settings are recalled when the DNS 8 Live is next turned on.
You can also determine which settings method will be used when the unit is restarted via the Setup/Options menu. The following options are available:
There are a two known causes for this:
Clock is derived from AES inputs 1 and 2 only. Check that you are not trying to sync to higher numbered inputs.

Apart from the obvious hardware differences, sdnx differs from the CEDAR DNS 2 and DNS 8D dialogue noise suppressors by offering a modified algorithm optimised for Sound Devices systems. This features a simplified user interface with a single attenuation control per channel that allows the user to ensure that the noise is being removed without damaging the wanted signal. Although it lacks the DNS 2's bias control and freeze function, sdnx performs almost identically with a DNS 2 that has its bias set to zero (optimal) and LEARN permanently enabled.

Yes. It is authorised for use with all macOS operating systems from OS X 10.12 (Sierra) onward and from MacOS 11.0 (Big Sur) onward. It may also work on some legacy systsems running on OS X 10.9 - 10.11, but these are not supported.
The CEDAR HASP dongle is not compatible with Mac OS X 10.12 onward or Pro Tools 12. You will need to transfer your licences to an iLok account to continue using CEDAR Studio.
If you wish to transfer existing CEDAR Studio licences from HASP to iLok, send the following information to ilokupgrade@cedaraudio.com.
We will contact you following receipt of this.
Current versions of CEDAR Studio for the Mac are not compatible with versions of OS X earlier than 10.9, or with versions of Pro Tools earlier than Pro Tools 11.
No. You will need a physical iLok.
There are four conditions that prevent CEDAR Studio VSTs from appearing in your plug-in lists:
Use the Copy and Paste Special commands under the Pro Tools Edit menu to copy each control parmater one at a time. The following video illustrates this.
Download and check the CEDAR Trinity Enhance manual before raising a support request.
Noise reduction processes for broadcast, mastering and other pro-audio purposes are designed to remove noise in a way that makes the wanted signal sound as listenable as possible, while those for audio forensics are designed to make the audio as intelligible as possible. 'Listenable' and 'intelligible' are not the same thing - it may be possible to make something sound nicer but with no increase in intelligibility, while it may be possible to make something else sound more intelligible while at the same time damaging the 'niceness' of the audio. It's therefore necessary to have different types of filters for the two jobs.
Yes, you can download the Trinity Enhance guidance notes here.
The original v1.0 software is compatible with all versions of Windows 7 through to Windows 10 and with macOS 10.9 to macOS 10.14.
To run Trinity Enhance on a Mac running macOS 10.15 (Catalina) or macOS 11 (Big Sur) you must install v1.1. This is also backward compatible to macOS 10.12.
No, there's no charge. To upgrade, contact support@cedaraudio.com to request the upgrade.
Full documentation is available on your CEDAR Cambridge system as context-sensitive Help and as a printable .CHM file.
Many Windows updates contain security features that help to protect the host system so we recommend that you allow it to update itself. We are unaware of any CEDAR Cambridge performance issues caused by Windows 10 updates.
The CEDAR Cambridge software and its installation is highly optimised, so adding additional hardware and software may degrade performance or lead to errors. Consequently, we advise against this.
