Nobsound TDA1541-2.0P OS/NOS DAC Digital Audio Decoder 2nd PLL USB/Coaxial/Optical
Description
- Receive AK4113 (software mode) + control CPU + PCM2706 USB input, and add a 2nd PLL circuit before the SAA7220 and 1541 chips.
- It adopts imported high-precision 10PPM, low phase noise and local crystal oscillator with jitter value of 0.52PS.
- In order to ensure high precision and high phase-to-noise ratio of the clock, some components of the 2nd PLL are simplified to use only three main components, to avoid the deterioration of the clock signal by using too many components.
- The current mirror technology is used for current amplification, and then the IV+JFET tube is used for buffer output. The advantage is that there are very few small signals lost, and thus the reproduction of the audio signal is very good.
Reasonable Component Matching: The digital-analog power supply is composed of discrete components. The digital receiving and filtering part of the 2nd-PLL is powered by a set of vertical components + op amp servo precision voltage regulator circuit. TDA1541 power supply +5V, -5V and -15V use three independent discrete parts regulated power supply. Analog output power supply also uses two-component vertical parts + op amp servo precision voltage regulator circuit This machine uses up to 7 components of the regulated power supply Adopt 50W-R type transformer Sound Features: In the medium frequency, the extension of the two ends is wider, the resolution is higher, the details are complete, the medium frequency is gorgeous and round and full, the words are clear, the low-frequency details and the sense of volume play the symphony level clearly and dynamically. The sound field created is stable and the sound field is accurately focused. Front Panel: The left side of the front panel is the channel selection button with light. When the signal is received and locked, the blue indicator light is on, no signal it will flash. On the right, there are three input channel indicators. The selected one is orange, and the other is green. Parameters: Chassis material: all aluminum Chassis size: (W)190mm*(H)70mm*(D)320mm Working Voltage: 110V/220V Receive signal frequency: 44.1KHZ Input: coaxial / optical / USB Output: Stereo L/R RCA Packing List: 1*Digital Audio Decoder
