North Star Essensio Plus

De North Star Essensio Plus 192 kHz-32 bit USB DAC is het muzikale hart van uw digitale systeem. Vijf S/PDIF digitale ingangen voor coax en Toslink aansluitingen en een hoge snelheid (480MBit/s) asynchrone USB-ingang die streamt tot 192 kHz-32bitis. Alles wat je nodig hebt om alle digitale media op uw hifi-installatie af te spelen. 
Maar de Essensio Plus is meer, een multifunctionele bedieningsknop laat ingangsselectie en de volume-instelling voor de analoge lijnuitgang en hoofdtelefoon uitgang. De hoofdtelefoon wordt aangedreven door toegewijde kwalitatieve versterker. Een configuratie menu voor het perfect matchen van de Essensio Plus met elk versterkersysteem .

 

Volume Control:

The ESSENSIOplus offers a high quality circuit design without to add any additional part for the volume control.
So the volume control is made in two ways. In the ESSENSIOplus setup it is possible to fix the analog overall gain in 3 positions:
Gain 1 4Vrms 0dB
Gain 2 2Vrms 0dB
Gain 3 1Vrms 0dB

This is possible using an analog switch in the analog stage. This is the main analog volume setting.
The customer needs to match gain regarding the headphone sensitivity or the connected power amplifier or the connected powered speakers.

The fine volume setting is made in the digital domain via the DAC. The PCM1795 DB allows to fine setting, 0,5dB step, the attenuation of the analog output. So matching the right overall gain and the minimum attenuation you can have the better volume control. This system is similar to some preamplifier that have a double volume control, main and fine. In this DAC the main volume control is analog and the fine is digital.

The advantage of this system is:

  1. The perfect matching between the channels.
  2. Benchmark is using a volume control with an analog potentiometer.
  3. This system could be potentially better but for high attenuation the channels are not balanced.
  4. There could be a difference of up to 5-6 dB between the channels.
  5. This solution need also an additional stage with respect our solution.


Jitter Cancellation:

Apart the USB input that use asyncrhonous transmission and clock reconstruction on board, also the other input have a similar system at the upsampling section. The unit (like the Essensio), made the upsampling at 192/32 on any input. But this section made also a jitter reduction at a very low level (2-3ppm at the 25°C) since the clock use like a reference for the upsampling have a very high precision on the thermal range 10-55°C.
