Starting up Nativ Wave for the first time.
When you turn on the Nativ Wave DAC for the first time it will walk you through the most important settings.
The Up/Down/Left/Right and Center button refer to the capacitive touch buttons on the glass surface right to the two OLEDs:
Use the Up & Down buttons to navigate between the different setting options and the Left & Right buttons to adjust each setting option. To confirm each setting navigate to the CONFIRM option and then tap on the Center button.
1. Display Settings
The display settings allow you to define what you want to see on the left and right OLED.
The settings are as follows:
Define if the 2 OLEDs should always be on or off.
Left and Right Display
You can decide which information will be displayed on the left and right OLED. The following options are available:
a) Audio Signal Data
Provides details about the incoming audio signal.
If MQA music is played the OLED will inverse its colors:
b) VU Meter and Spectrum Analyzer
You have the option to show the Spectrum Analyzer or VU Meter for both channels (Left + Right) or for one channel only. Both channels makes sense if you want to show the information on only one OLED, separate channels is more useful if you want to show for example the left channel on the left OLED and the right channel on the right OLED.
Note: VU Meter, Spectrum Analyzer and MQA support might be implemented later and not be available in Version 1.0. You will be able to update the software of your Nativ product via USB stick to add these features for free.
2. Filter Settings
Nativ Wave DAC provides several Finite Impulse Response (FIR) filters to allow you to adjust the sound performance to your equipment. The available filters are: Linear Phase, Minimum Phase, Slow Roll-Off, Fast Roll-Off, Standard Attenuation and Anodizing Attenuation*.
3. Gain Settings
Depending on the type of Amplifier or Headphone you can set the gain to either 2.0 VRMS (standard) or 7.5 VRMS.
Note: The volume control on the Nativ Wave DAC & Headphone Amplifier works for both the analog outputs and the headphone output. The gain settings are for the analog outputs only.
4. Input Settings
Define which audio input is the default for your Nativ Vita DAC. Options are USB (Default), AES/EBU, RCA (S/PDIF 1), BNC (S/PDIF 2) and Optical/Toslink.
5. Upsampling Settings
Process the audio bit-perfect or turn on the DSD upsampling (to 128x Fs).
6. Volume Settings
The volume on the analog outputs and headphone amplifier can be adjusted with the + / + + and – / – – buttons inside the 2 circles on the front side of the Nativ Wave DAC. The + / – buttons adjust the volume with a finer graduation of 1dB per tap, the + + / – – buttons adjust the volume in bigger steps of + / – 5dB per tap.
* Want to know what these Finite Impulse Response filters do? Here is a short description of each filter category. Sorry, it is written by one of our engineers so it might be a bit hard to “digest” for the less technical among us:
- Linear Phase filters only affect signal amplitude. The phase response of the filter is a linear function of frequency and consequently there is no phase distortion. However such filter response introduces moderate amount of pre-ringing and post-ringing.
- Minimum Phase filters only add post-ringing artifacts, but show a higher amount of post-ringing than that of a Linear Phase filter with the same frequency response. Furthermore Minimum Phase filters introduce a slight phase shift that increases with frequency.
- Apodizing filters are designed for a full attenuation at the Nyquist frequency, in order to avoid any aliasing artefacts. The cut-off frequency is slightly lower compared to a non-apodizing filter.
- Fast roll-off filters offer an optimal spectrum with a high attenuation of the high frequency noise. Slow roll-off filters offer better transients while having less optimal spectrum linearity and high frequency attenuation.
