RACOON SG100A 24Bit/96KHz High-Quality USB DAC Headphone Ampliifer

Description:
Amp / amplifier separately two modules, power supply independently, without disturbing each other influence;
Plug in your headphones, amplifier output is disconnected, the status indicator lights red, unplug the headphones, the amplifier output is automatically connected, the status indicator shows green;
USB DAC part of the mainstream TE7022L, CS4398 and other specialized chips, enabling you to enjoy high-quality sound effects;
Amp part is not tasteless, using an independent power supply, the mainstream TPA6120A2 power amp chip to do the main thrust powerful, high enough to push the full 300 ohms headphones;
Amplifier with built-in switching power supply, NXP TFA9815T high-efficiency Class D digital power chip, 550KHz/600KHz two different carrier channels designed to achieve high-fidelity conversion while avoiding interference, 0 dead zone design and a perfect protection function: overheating , overcurrent, overvoltage, undervoltage, power comes detection protection, output power: 18W * 2,4 ohm load;
Power input section perfect EMI and safety regulations designed instant boot limiting protection, lightning surge protection device, CLC filtering radiation designed to ensure the supply of pure;
Amplifier output inductor using magnetic shield against electromagnetic radiation quality material design, the current foot 4A, not hot, provincial consumption is very low, so that the power output signal quality, efficient.

Features:

24Bit USB DAC chip uses high-quality professional integration TE7022L TENOR chip, support the highest rate of 96KHz output, the chip wide frequency response, high resolution, I2S digital signal by the high-frequency filter chip DAC decoding transferred to the subsequent stage, the computer transmission of digital base noise to a minimum.
DAC decoder chip used CIRRUS LOGIC company's top digital / analog converter CS4398 chip, its up to 120dB signal to noise ratio and dynamic range parameters, providing a high level of audio resolving power, and supports up to 24Bit/192KHz perfect digital signal D / A Solution tone.
Amp power chips using current hot Texas Instruments TPA6120A2, the chip with extremely low distortion and high conversion speed and supports a variety of high and low impedance headphones, headphone impedance range is 8-1000 Europe, output power peak - peak range is 2.7W -100mW, strong thrust, easily drive all headphones.
Amplifier using NXP TFA9815T high-efficiency Class D chips, 550KHz/600KHz two different carrier channels designed to achieve high-fidelity conversion while avoiding interference, 0 dead zone design and a perfect protection function: overheating, overcurrent, overvoltage, undervoltage, power comes detection protection, output power: 18W * 2,4 ohm load.
Fast boot and shutdown time delay relays disconnect function, completely avoid momentary switch circuit imbalance, causing shock SPEAKER DC output, thus extending the life of horn speakers, but also to avoid the harsh plosive generation.
Usb Digital Analog Line with two input signal selection.
Insert the headset into the 3.5mm jack, the amplifier output is automatically disconnected from the outlet 3.5mm headphone plug, automatically connect the amplifier output work, avoiding the amp and amplifier mutual influence, to ensure a good listening environment.
DAC, preamp, amp using conventional EI type transformer power supply, pre-amp output and low noise; amplifier section with built-in switching power supply, fully regulated power supply and protection circuit design, power amplifier more stable.
AC power at the local EMC EMC circuit design, in full compliance with electrical safety standards, in line with UL, CE, CCC national and regional safety standards, to avoid electromagnetic radiation of the machine and the use of external security, to make your personal health security is guaranteed.
