Produkto aprašymas
Naim DAC-V1 keitiklis su pradiniu ir ausinius stiprintuvu dažnių juosta: 10Hz – 20kHz, +0.1/-0.5dB, THD: <0.002% | Nemokamas Pristatymas
Nuo šiol turite galimybę sujungti ir atnaujinti beveik bet kurią iš Naim Audio sistemų, šis DAC turi daug bendro su mūsų CD grotuvais nei bet kurie kiti DAC keitikliai. Tai "Burr-Brown" keitiklio mikroschemos kurias galima pamatyti ir mūsų aukščiausios klasės CD grotuve - "CD555". Šis DAC iki minimumo sumažina visus iškraipymus kurie galimi standartiniuose skaiteminiuose įrenginiuose.
Verčiant signalą iš skaitmenos į analoginį yra pasitelkiamos "SHARC DSP" mikroschemos pagrindas. Tai unikalus Naim Audio kodas, kuris nustato naujus standartus šioje klasėje. Mūsų DAC dabar suderinamas su DSD formatų atkūrimu ir gali atkurti 64 bitų (2.8MHz sample rate) ir 128 bitų (5.6MHz sample rate) failus. Atnaujinimas reikalauja ypatingos DSP branduolio optimizacijos kuri pagerintų garso kokybę.
Features

- Five S/PDIF inputs for digital sources like games consoles, set top boxes and hard disk servers
- Selectable fixed or variable analogue outputs (DIN or RCA)
- Naim Audio digitally controlled analogue volume control for performance and precision 40bit SHARC DSP chip handling filtering and oversampling
- Single-ended class-A headphone amplifier output
Technology & Craft
Asynchronous USB Explained
Digital audio isn’t just about the data – 0s and 1s – and ensuring that each sample value is accurately converted into a corresponding output voltage. Also vital to achieving the highest fidelity is ensuring that each successive sample is reproduced at a precise time interval from those around it. If that time interval varies – an effect known as jitter – then the output waveform will be distorted. To prevent this, the master clock that controls the process should, ideally, be placed right next to the digital to analogue converter circuitry, not remote from it. Asynchronous mode USB provides for this because it allows data to be ‘pulled’ from the source as required, whereas in other modes the data is ‘pushed’ down the interface under control of the far inferior and distant clock in the computer.
World class headphone amplifier
The single-ended Class-A headphone amplifier of the DAC-V1 cleverly uses the pre-amp output amplifier for headphone drive. The moment headphones are plugged in, the output current drive is automatically turned up five times to give dynamic drive for all headphone impedances. The amplifier runs from a high voltage power supply so has the ability to drive high impedance headphones with the voltage swing they require for open and dynamic sound. The result is the audio stages are kept as simple and pure as possible for both normal and headphone modes.
