The performance characteristics:
- The machine has a 5 ways switch signal inputs :
Analog part : 2 x RCA inputs, you can connect your CD playeror another RCA sound source, let DAC-01A improve or control your sound source.
Digital part : Coaxial, Optical, USB.
- The machine has two stereo RCA outputs :
OP-amp normal output OR Tube buffer output . convenient tube amp or transistor amp, to get different effects.
- main amplifier board with dual-panel design , production of fine .
- The machine is also designed with headphone amplifier output , the circuit reference classic lines , the use of integrated operational amplifier + discrete pieces in the form of the power flow on the tube expansion , late -stage amp current amplification using emitter follower , because pushing the headset , the current does not like amplifier that requires a lot of current, so do not have a small emitter resistor values , which can increase end -stage feedback , reduce distortion and improve stability. Joubert and add a network to prevent high-frequency self-excited oscillation .
- To protect the headphones, plus there is the output resistance and output capacitance , in order to ensure that the sense of hearing , the use of large -capacity electrolytic capacitor in parallel with the small-capacity monolithic way to make high low-end signal coupling smooth.
- With a variety of headphones actual audition , driver well structured, clear details , the intensity is good, there will be improvements to upgrade the op amp for playing machine sent Shaoyou provides headroom.
- The digital part is not entered automatically muted
- The machine headset promote and isolation buffer using National Semiconductor 's LF353N ( FET input dual op amp , warm and delicate )
- The machine resistors, capacitors are of high quality discrete component assembly fever , so the sound quality is guaranteed , but also easy to replace the friction drive components .
- The machine uses a lot of fever quality components : 1/8W metal film resistors, Germany WIMA polypropylene capacitors , CBB subminiature metallized polypropylene capacitors, monolithic capacitors. Never use of polyester , tiles and other common components. Thus ensuring pure sound , high resolving power , small bass , a wide sound field and so on.
- knobs and buttons are made of metal knobs and buttons.
- indicator with blue LED.
- Using superior performance of R-type transformer power supply ( generally only the high-end equipment will be using ) , although the cost ratio circular , square transformer greatly increased , but high efficiency, small magnetic leakage . Digital and analog part of the independent power regulator rectifier filter to reduce interference.
- Volume potentiometer make in Taiwan .
- In order to ensure a limited budget , get a good musical , the machine saves the display portion dispensable .
- Block RCA analog inputs , RCA line outputs seat , plated coaxial ports , reducing the contact resistance.
- The machine tuning cf desktop CD models: Octopus HD-22, the sound Ya S-10CS, Zhu Lida JD100 and so on.
- The machine tuning cf similar products : lezhibang MD-10, lezhibang SVDAC05, Ian Van ZERO decoders .
