Fidelizer Nimitra Firmware 4.0 Updater is released with Device/Sound Signature Profile options

 

Nimitra Firmware 4.0 Updater

 

It’s been a long while since last time I released Nimitra Firmware update. There’s a lot of on going internal optimizations and improvements with Nimitra after 3.0 release including new platform and supported protocols.

Version 4.0 will cover many changes and improvements on NimitraOS platform and also updater itself. Here’s summarize about major updates in version 4.0:

 

Added Device Profile and Sound Signature Profile configuration options

 

Nimitra Firmware 4.0 Updater - Main

 

Device Profile is Fidelizer Pro’s Audio Profile but I changed wording to device to avoid confusion. Nimitra will be configured as Network Player by default for general purposes but you can choose different profile for Nimitra to work with specific device better now.

For example, you can change option to Streamer for better sound quality with Network Player/Endpoint device. You can also choose Audio Player if you don’t use streaming or networked storage at all too for better optimizations.

Sound Signature Profile is a unique new configuration added in NimitraOS sound quality optimizations platform. Some clients prefer to have analogue sound reproduction but there’s also those who prefer high resolution with finer details.

You can choose sound signature of Nimitra to match with your system better. Nimitra will be configured with real sound signature profile but both options are good in different aspects so you can try both and pick what you prefer more in your system.

 

Support AirPlay, Logitech Media Server, OpenHome (Lumin / Kazoo) platform

Current models of Nimitra will have new platform integration support by default and older model can be configured to launch them too with remote support. If you want to use these features, please contact Fidelizer support for remote assistance.

 

Improved compatibility with JRiver and JPLAY7

In this update, JRiver will always scan for music in libray during startup reliably to make sure you won’t miss any new added track. JPLAY7 will also have Nimitra’s recommended configuration and optimizations on its services to be more reliable too.

 

Improved NimitraOS core sound quality optimizations and quality of life improvements

After over 2 years of firmware 3.0 update, NimitraOS has been improving with internal updates through time with clients and firmware 4.0 will bring better sound quality standards. Besides sound quality improvements, boot time is also decreased also.

 

Changelog

-Added AirPlay/HQPlayer NAA/Logitech Media Server/OpenHome integration support
-Added device profile option to optimize Nimitra device for optimal sound quality in different setups
-Added external application launcher support
-Added sound signature profile options to choose between real sound performance and audiophile sound performance
-Changed audio detection notification message to “Audio ready”
-Changed JRiver platform to always perform full library scan on startup
-Fixed JRiver startup issue on 64-bit platform running 32-bit version of JRiver Media Center
-Fixed Windows update failing to be turned off completely on some early units
-Improved compatibility with JPLAY7 and its Femto service
-Improved MinimServer optimizations to work with renderer platforms better
-Improved NimitraOS sound quality optimizations for better sound quality
-Improved optimizations with dual core processor server such as Weiss MAN301
-Improved platform optimizations code to decrease boot time
-Updated HQPlayer NAA daemon software to version 4.11

 

Nimitra runs on specially tuned NimitraOS platform with special version of Fidelizer. All these optimizations are specially tuned for Nimitra’s hardware and software configuration, separated from Fidelizer 8 optimizations.

Nimitra/NimitraS customers can send request for firmware update and I’ll update Nimitra firmware through Teamviewer or request download link for applying update manually. This update is highly recommended for all Nimitra users.

Introducing AirStream, Audiophile Wireless Router from Fidelizer Audio

 

AirStream - Wireless Router

 

Today I’d like to introduce a new product I’ve been working for over a year now. It’s a wireless router with modification that can bring high fidelity audio in the air for the first time. You could call it wireless version of EtherStream for devices that you can’t use wired connection with.

I chained EtherStream with WiFi router for improved WiFi signal to use with my smartphone and my desktop computer in bedroom. They sound a lot better but still miss important information compared to direct wired connection. AirStream will deliver those missing bits.

I examined and modified a few routers in market and chose ASUS RT-AC1300UHP that has very good flagship design with quad core processor. I applied modification based on EtherStream with a lot of adjustments for over a year, tuned with EtherStream and Nikola.

 

AirStream with EtherStream + Nikola Classic combo

 

Some may feel skeptical towards wireless improvements but wireless radio modulation and pulse amplitude modulation shares similar basics on modulating data with time domain. After a lot of research and development, here’s how Fidelizer brings high fidelity audio to the air:

-Upgrade Capacitors with high capacitance and low impedance tuned in 3 different stages for optimal sonic performance
-Upgrade Safety resistors with high power from Vishay Dale on DC input stage, power regulation stage, and isolation transformer stage
-Re-energize power supply with special tantalum capacitors to reducing noise and interference in processor chip effectively
-Crystal clock is upgraded with high precision clock optimized for network application with noise reduction tweaks
-Components are soldered with high quality solder providing solid bass and dynamics
-Router is configured for low-latency audiophile streaming applications

AirStream will be configured as an access point by default so you can connect AirStream to main router and enjoy high fidelity wireless streaming through new WiFi network as plug and play. You can submit an order with your own WiFi name and password.

Personally, I don’t use wireless connection on Nimitra server but there’s a lot more areas in my audiophile’s life outside main system. I also listen to music and watch video from smartphone and PC in my bedroom so AirStream will improve my enjoyment outside listening room.

The product price will be $495 USD with 30-day money back guaranteed and free shipping until 31st May 2021. You can read more about AirStream Wireless Router product in details before ordering and happy listening. 🙂
