Hellojust wanted to chime in on this. I am also starting to notice a new issue using Cubase Pro 10.5 on Windows 10 x64 w/Focusrite Scarlett. This setup has been working fairly stable for about 6 months. As of a few weeks ago, for some strange reason, Cubase loses connectivity with the audio interface. The only want to restore it is to close and re-open Cubase.

Enjoy Nureva Pro free for 2 years, including expanded support hours, advance hardware replacement and enhanced Nureva Console features. You can also add up to 3 years to your subscription to keep these features and extend your warranty.


One of the most popular features of the HDL200 (and all Nureva systems) is the fact that we keep adding features and making improvements. To get regular firmware updates, be sure to register your system in Nureva Console.


When two people talk at the same time, the HDL200 system focuses on the stronger signal (the louder voice), while the other voice drops into the background. The effect is as if you were standing in the room close to the louder talker, but are also aware that someone else is speaking at the same time.


Unlike approaches that apply gain to all sounds equally within a microphone pickup area, our technology modifies gain according to the position of each sound source in the room. This lets us make specific optimizations to both the microphones and the processing of each sound source. Remote participants have an easier listening experience without the distraction of uneven audio.


Automatic gain control keeps audio output levels within range by adding more gain on soft talkers. But both the talker and ambient sounds are treated equally, resulting in increased levels of background noise when people speak quietly. This can be very distracting to remote participants.


We accommodate both loud and soft talkers by providing gain appropriate to the sound source position in the room while keeping ambient noise consistent. The result is a signal-to-noise ratio appropriate for that position, which directly translates into a less fatiguing remote experience.


Set the active zone for the required dimensions at the front of the room, and the person speaking can be heard more clearly while sounds and voices from the rest of the space are suppressed. It adds up to better audio for remote audience members and lecture capture.

One of the most popular features of the HDL410 (and all Nureva systems) is the fact that we keep adding features and making improvements. To get regular firmware updates, be sure to enter the code found on the bottom of your connect module into Nureva Console.

With 8-sources and 8-zones, the DAX88 delivers the ultimate customizable multi-zone audio experience. Engineered with an emphasis on simplicity, flexibility, and wireless control, the DAX88 provides you with unrivaled multi-room audio for your home or business. Delivering 75 watts per channel, the DAX88 has enough power to give you an immersive listening experience all across your home or business. Featuring the ability to bridge channels, the DAX88 produces even more power at 180 watts.


The DAX88 offers a wide array of analog and digital inputs, including integrated Wi-Fi (AirPlay, Spotify Connect, DLNA) streaming options. Featuring a dedicated Wi-Fi channel, the DAX88 allows you to stream your favorite music directly from your preferred streaming service through AirPlay, Spotify Connect, and DLNA. With access to streaming services such as Spotify, Apple Music, Amazon Music, TIDAL, iHeartRadio, and TuneIn, the musical world is in your control. Additional hardware and or paid subscription may be required for Amazon Music, and other streaming services if you are using Android devices. Analog input options, including four RCA, seven 3.5 mm, and two optical connections, ensure you can use virtually any input source from TVs to media players and additional Bluetooth adapters.


The output flexibility that the DAX88 provides lets you choose your speaker system or integrate the DAX88 into an existing design. With six stereo amplified zones and two stereo preamp zones, the DAX88 gives you the option to use any speaker combinations as well as additional amplifiers. Using the preamp zones with different amplifiers such as 70V commercial-grade amplifiers, the DAX88 instantly provides app-controlled and Wi-Fi streaming options to your 70/100V audio system.


If you need quick, accessible zone control, the DAX88 gives you the ability to access total command of the DAX88 via in-wall keypads. You can connect up to eight keypads throughout your home or business that give you direct control over volume, power, bass, treble, mute, and source selection. The keypad has a built-in IR target for use with the DAX88 remote. Also, the keypad has an external IR target terminal if you want to use an additional target in another location.


The DAX88 allows you to connect up to eight control keypads per device. With the DAX88HUB, you can connect all of your keypads to the DAX88 with one ethernet connection. Each keypad connects directly to the DAX88HUB via an ethernet cable. The DAX88HUB then connects to the DAX88 with a single ethernet cable to simplify installation and reduce wire clutter.


Teensy 4.0 & 4.1's I2S port has a total of 5 data pinswhich may each transmit or receive stereo digital audio. This6 channel input may be used together with the I2S stereo orquad channel I2S output, but may not be combined with otherswhich use the same physical pins.

The windowed (Kaiser window) sinc-function is used as resample filter (i.e. to interpolate the incoming signal). The longer the filter, the better the quality of the resampled signal. However, a longer filter has a higher group delay and increases the processor usage. The sinc- filter also serves as anti-aliasing filter if the input sample rate is larger than 44.1kHz. The filter length is automatically increased at high input sample rates to reach the specified attenuation. However its half length is restricted to 80. 32bit floating point arithmetic is used at the resampling stage and the resampled signal is transformed to 16 bit integers afterwards. Here it is possible to apply triangular shaped dither and noise shaping to increase the perceived signal-to-noise-ratio.


Low impedance (strong) drive is required. The ADC pin picks upa lot of noise from inside the chip. A strong signal isneeded to overcome this noise coupling. DO NOT leave theinput pin disconnected. Strong noise will occur if theADC input pin is left floating!


analogRead() must not be used, on Teensy 3.x because AudioInputAnalogis regularlyaccessing the ADC hardware. If both access the hardware at the samemoment, analogRead() can end up waiting forever, which effectivelycrashes your program.


Noise coupling from digital circuitry inside the chip is always a problem when usingADC inputs pin. It's never as quiet as the audio shield and any good qualityaudio ADC chip. Stong low impedance drive to the analog input pin is criticalto minimizing noise coupling. If an opamp is used, connect a low value resistor(eg, 100 to 1000 ohms)between the opamp output and ADC input pin, and a 1nF capacitor from the ADC pinto GND or AGND. The capacitor lowers the impedance for high frequency noise,and most opamps require a resistor to avoid oscillation when driving acapacitive load. Strong drive from an opamp, 100 ohm resistor and 1nFcapacitor can greatly reduce the digital noise coupling.
