NEW arrive remote control xiangsheng DA-02AII double 1794 audio decoding headphone preamplifier Product specifications: ★ Dimensions: Width 260mm, Depth 167mm, Height 55mm (excluding knobs and machine) Foot and connector dimensions ★ Frequency response: 20Hz~30KHz ★ Signal to Noise Ratio: Normal output: 110dB; Gallbladder output: 90dB ★ Harmonic distortion: Normal output<0.001%; Gallbladder output<0.1% ★ RCA output level: 2000mV ★ Dynamic range: 120dB ★ Input impedance: 5 ohms ★ Output impedance: 600 ohms ★ Net weight: approximately 1.75KG
Characteristics● Has 4 inputs: USB coaxial, fiber optic, BnC (with Bluetooth occupying BNC). ● It has two sets of RCA outputs: operational amplifier output and gallbladder output, making it convenient to connect the gallbladder machine and the stone machine to obtain the desired output Same tone color. It is also designed with independent headphone output. Aluminum alloy wire drawing process front panel, thin steel plate spray box, well shielded. Built in R-N power supply, not a small box with an external switch power supply. ● Digital and analog are truly independent: transformer independent winding, independent rectification and filtering, independent multi-stage Stabilize voltage. ● Dual core PCM1794 A decoder+C58416 receiver+D2256 electronic volume+SGM4809 headphoneLet it go. CD2256 is a CMO chip with internal step resistor control for volume, featuring high separation and low distortion Long lifespan without noise. SGM4809 can output 158mW/16 ohms with comprehensive protection??? Turn off mode. Operational amplifier: 2 pieces of 0PA612AIDRGR, 1 piece of OPA2604AU Vacuum tube: 1 6N3 electron tube. Bluetooth with optional Qualcomm OCC3084 module, supports LDAC, APTX-HD lossless High definition format. You can contact customer service to pay for upgrading to Qualcomm QCC5124/5, SCR675, etc.
