HIFI Tube Advanced Digital Decoder Remote Control with Headphone Amplifier
Model No: WVDA-03A
It is a HIFI digital advanced decoder with vacuum tube output and headphone amplifier output, which adopt TI's top-amp chip TPA6120. Digital and digital to analog conversion adopt receiver CS8416 of CIRRUS, TI's PCM1794A and USB part is SA9027, and active crystal to reduce the USB port clock jitter.
The unit adopts U.S. tube of GE5670 with warm and mellow tone sound style. High voltage and filament are regulated DC power supply.
The decoder also has a remote control function to achieve channel switching, volume addition and subtraction, mute, etc., and has a memory function, the next boot automatically shut down when placed in the state. Customized self-reset switch and volume switch 360 degrees, feel good!
Custom miniature remote control handle, practical and lightweight.
In addition to the USB port supports 24bit, 96K, coaxial, fiber optic, BNC really support 24bit, 192K!
1. The unit has four digital signal input switching: BNC, coaxial, fiber optic, USB. And it has two unbalanced stereo RCA output: Normal output, tube buffer output. With convenient tube amp or transistor amplifier, you can get different effects.
2. Main amplifier board with two layer designed, production of fine.
3. The resistors and capacitors do not adopt SMD components, but are of high quality discrete HIFI component assembled, so the sound quality can be guaranteed. The unit uses a lot of HIFI components like as the light tone DALE metal film resistors, Germany WIMA polypropylene capacitors, Suren capacitor, CBB subminiature metalized polypropylene capacitors, monolithic capacitors. Never using of polyester, tiles and other common components. Thus ensuring pure sound, high resolving power, small bass, and a wide sound field and so on.
4. Indicator with blue LED.
5. Uses superior performance of R-type transformer power supply (generally only use high-end models only), although the cost ratio circular, square transformer greatly increased, but high efficiency, small magnetic leakage.
6. Digital and analog part of the independent power regulator rectifier filter to reduce interference.
7. Gold plating for the terminals of RCA analog inputs, RCA line outputs, plated coaxial ports, reduce the contact resistance.
