Rosanna Diretta Network Bridge Listening Impression

[Johnnydev]

Maybe I'm making a big mistake. 

Can the Rossanne diretta only be installed and used with a Windows computer? I only use an I pad pro? 

how does installation and operation work? 
 

Who can help me? I am not a computer nerd and my english is not so good

In order to work, diretta needs to pieces of hardware : a "target" which is in this case the Afterdark Rosanna, and a "host". This host can run under :

• windows with the ASIO drivers provided by Afterdark
• Linux using some OS like Gentooplayer or audiolinux that are onboarding the Diretta drivers. This host needs also to onboard a server (roon, UPnP, LMS, audirvana,...)

Your iPad can be used as a remote (with Roon, JPLAY iOS, audirvana, etc...).

 

As mentioned in a previous post by Afterdark, in order to make it run also on your Devialet Phantom, you need a DCC to convert the usb output of the Rosanna into a input the Devialet accept like SPDIF or TOSLINK.

 

Hope it clarifies.

Not completely, sorry.

The diretta rosanna is plug en play. Can i change the settings for Roon, Hq player and diretta just with my ipad like i do now with Roon on a NUC? 

For my devialets i think i will go for an other dac or a good DCC to convert spdif or toslink

2. Basic Setup Procedure for Diretta :

1. Install the above ASIO software, the computer in Windows will become Diretta Host. 
2. Please connect the USB cable to DAC, BNC clock cable to external 10M Master Clock, lan cable to the network. 
3. Power up the Rossana Diretta NB by input the external 5V LPS to the DC Socket first, it will start the Giesemann Clock Sync and Fiber Isolator with LED on. Then turn on the switch at the back will start the Diretta Module, and the boot up time is around 4 seconds. The Rosanna will become Diretta Target. 
4. Then open the ASIO software by entering Diretta ASIO Configuration apps. Press Find at the right, will automatically shows the "AfterDark. Diretta_Bridge" - XXNAMEXXX DAC at the Connect Target. 
5. When the name of your DAC shows, It can confirms it is ready to play music with Diretta. 

 

3. Music Playback Support Matrix:  

 

 

4. VB-Audio ASIO Bridge for music passthrough via Rosanna Diretta NB: 

• This program can turns the Rosanna Diretta NB as a sound device in Windows, it will be very handy and flexible for movie lover to play movie via Netflex, Disney Channel, football game steaming or other music streaming service to playback music via audiophile DAC. 
• This function can avoid to purchase other HDMI to Optical convertor or cables to play music to DAC while maintain highest quality of music playback without any digital convertion. 
• This is a freeware to use and the download link is: 
  • https://download.vb-audio.com/Download_CABLE/HiFiCableAsioBridgeSetup_v1007.zip

By Pressing the ASIO On, The Diretta ASIO will enable and ready to passthrough Sounds to Rosanna Diretta NB  

 

5. Rosanna Diretta Network Bridge as Roon End Point Player via ASIO: 

• The Rosanna Diretta Network Bridge can turn all Non-Roon Ready USB DAC, becomes Roon End Point Player via Diretta ASIO, at Roon Audio setting, the Rosanna Diretta will shows as AfterDark Diretta - ASIO sound device.  

 

6. Rosanna Diretta Network Bridge as Audirvana Player via ASIO: 

 

7. Diretta Target Configure in Windows GUI

• The most interesting function of Diretta is the combination of Diretta settings
• We recommended to start tuning with the major function - ASIO Preset Profile
  • The default setting is TargetProfile. 
  • We recommended to use Variable_Low or Sync_Low which produces most natural soundings 
• Depends on your taste and DAC resolution, Audiophile may tried to fine tune with the other parameters at the GUI below. E.g. Preset Profile, The ASIO Buffer, Diretta Cycle, Target Latency, Phase. 
• When there is some setting is too extreme, such as ASIO buffer too low, some music may not play propertly and this can be fixed by increase some degree of setting. 
• Press "SAVE" after setting. 
• The Update at the right can be use to update the firmware of AfterDark. Rosanna Diretta Network Bridge and ASIO program from time to time. 

 

Update for Diretta Host Program and Firmware of AfterDark. Rosanna Diretta Network Bridge

 

8.Logic Behind the Diretta Host and Diretta Target 

• The Target and the Host are designed based on separate concepts.
• With regard to the Diretta Target, processing is minimized and simplified to enable averaging. The Target is configured by means of simple processing, like hardware processing by FPGA.
• The Diretta Host operates in synchronization with the Target to average processing by the Target. Packets are transmitted as often as possible at constant short intervals in order to average processing.The transmission is controlled by forecasting Target buffers. In this way, fluctuations in power consumption of a player as the Target is averaged as much as possible.
   

9. Advanced IPv6 access with Diretta for HQPlayer 

• Diretta is optimised with IPv6 network protocol, the Host is always synchronizes with Target and reduce infleunces with flow control and reduce complicated range requests process in UPnP.
• The sound quality is much outstanding with high smoother resolution when Diretta is partnering with HQPlayer after High Performance filers and upsampling to DSD 512 playback 

 

10. Rosanna Diretta Network Bridge is Plug and Play for HQPlayer. 

• Steps for activate the Diretta: 
  • Choose the Backend: From NAA to ASIO
  • The Deivce for ASIO will be listed, choose AfterDark Diretta
  • The parameters will not change and settting can be saved
  • Press Save, then it is ready to go. 

 

 

11. Connecting with Optical Fiber Isolator at Rosanna Diretta Network Bridge 

• Every Rosanna will comes with the small bridging lan cable in BLUE. The stock lan cable is useful for audiophile to try on the "Magic Effect" with optical lan isolator. 
• The BLUE cable is to connect both LAN port together, so that they can communicated. The SFP port will connect the SFP optical cable to network switch with SFP connection. This can provide phyical isolation from the noise swtich toward the Diretta Target. Music will be darker and details at the background will be increased.  
• For maximise performance, the stock lan cable could be upgrade with AfterDark. Constallation Ethernet Cable 

 

12. 10M Reference Master Clock Input for Sound Optimisation 

• This clock sync interface is a optional addon for Rosanna Diretta Network Bridge
• The Giesemann Clock Sync module is designed to accept 10M Master Clock from both sinewave or squarewave format. 
• The major sections of Diretta hardware will be benefit. It includes the USB, LAN port and CPU on Diretta and optical Isolator. 
• The addition of the external AfterDark. Giesemann 10M Master Clock can improve the soundstage and details of the Rosanna Diretta Network Bridge. The extraction of details from the background is just amazing and helps the DAC achieve the maxmium potential, balanced with enhanced timbre, full tone, and escpecially pace, rhythm and timing. 

 

13. External Power Supply requirement for Rosanna Diretta Network Bridge  

• The Rosanna Diretta Network Bridge will requires external 5V Linear Power Supply rated at 2A for operating the modules.

Hi! Johnnydev,

 

Thanks for your message and questions. 

 

As we know you are running Intel NUC with Roon Server, the Diretta Host software can be install and run in the same platform in Windows. So, you can access all the setting via Windows GUI. 

 

After install the Diretta ASIO software, the Rosanna Diretta Network Bridge will becomes a Roon endpoint player, so after adding a USB DDC such as Gustard U18 or Mutec MC3+USB. This DDC can convert the digital signal to Optical Toslink for connecting the Devialets. The music can play via Roon with Ipad. 

 

For HQPlayer it requires to purchase a license for HQPlayer 4 Desktop 4.21.1 Edition for Windows. All the setting in HQPlayer 4 Destop 4.21.1 is requires to access via Windows GUI.

The Roon can support HQPlayer by enable the service as below: 

 

Thanks and have a nice weekend.

Thanks for your clear answers Adrian. 

 

However, I received the NUC plug and play with roon on it. I only had to connect the ethernet cable to my router and was able to do everything right away from my ipad.

Hi Patatorz,

 

Thanks for your message and questions.

 

There is three USB ports on the Rosanna Network Bridge. So audiophiles can connect up to three units of USB DAC or USB DDC to use with Diretta. 
 

For USB ports they are controlled by one controller at the motherboard, so OCXO version will be optimised all three of the USB ports at the same time.

 

For best sounding, audiophiles is recommended to use USB 2.0 - a vertical one in white colour, USB2.0 generally run a lower frequency, which means it will be less noise when compared to USB3.0. 
 

From time to time, we explore the tweaks and optimised the hardwares in the motherboard of Diretta. This including applying the EMI protector material on Lan and USB port and provide the anti-vibration and ground plate with Carbon Fiber.
 

We shall give you more details on how we enhance performance with additional AfterDark. BLACKICE ground box to connect at the back of Rosanna Diretta Network Bridge. This can improves sounding with direct grounding on digital sections on the motherboard with single point grounding point with external ground box. This grounding technology is called AfterDark. Project ClayX AudiophileMAT Digital Grounding.

More information on how we modified and enhance with the Diretta Target will be released time to time. 
 

Thanks and have a nice weekend.

 

Best Regards,

Adrian

AfterDark.

I can tell that the afterdark Blackice ground boxes are very good for better sound quality.

i have in my system one Cu and two silvers to my router/NUC and to my two Etherregen. It is a great upgrade!.

This is not my question. Please clarify if your NUC is running windows, Linux or the dedicated OS of Roon : roon rock.

 

Roon remote is only the control point of roon server.

I think windows 🧐
