?<strong>Description:</strong> <br>TA-01 is a mini headphone AMP that consists of USB DAC and tube AMP. It supports up to 24bit/192KHz asynchronous USB DAC function. It adopts 12AU7 tube for pre-amp with warm timbre£¬ the post-amp is adopted OP+transistors for class A buffer£¬ built-in +/-15V for OCL(output capacitor-less) circuit£¬ so that it has not only soft nature sound but also not lose sense of speed. Its power supply is DC12V adapter£¬ through professional boost circuit£¬ make sure that tube is worked at its best condition. <br><br><strong>Features:</strong> <br>1. It adopts XMOS chip for USB signal input£¬ works at asynchronous transmission mode£¬ provides I2S interface for decoding£¬ can support up to 192KHz/24Bit USB signal£¬ can support WASAPI£¬ ASIO£¬ KS Kernel Stream Mode. <br>2. It adopts 3X Clock structure design£¬ ensures the DAC to obtain a first class sound performance. 3 correspondence level clocks are high precision £¬ individually control multiple of 44.1KHz£¬ multiple of 48KHz and USB signal transmission£¬ dedicated for USB asynchronous transmission£¬ and reduced Jitter to undetectable level. <br>3. It adopts the professional DAC chip WM8740*2; Built-in tube for pre-amp£¬ transistors for class A buffer. it has not only soft nature sound but also not lose sense of speed. <br>4. Built-in +/-15V for OCL(output capacitor-less) circuit. It uses 12V DC adapter for power supply£¬ through professional boost circuit£¬ make sure the tube is worked at its best condition; built-in 2-Setting Gain£¬ suitable for matching with different headphone. <br>5. built-in overvoltage / overcurrent protection£¬ so that it can be prevented damage to the amplifier if the input voltage / current exceeds the limit value; built-in mute circuit when turn on amplifier to avoid POP noise and make sure the tube is worked at its best condition; Use aluminum-shielded case to prevent external interference noise. <br><br><strong>Specifications:</strong> <br>Brand Name: XDuoo <br>Model Number: TA-01 <br>Technical Parameters: <br>Power Source: DC12V adapter <br>Output Power: 2100mW (32? load) <br>Compliant OS: Win XP£¬Vista£¬Win7£¬Win8 (must install driver) <br>? ? ? ? ?MAC OS X (do not need to install drivers) <br>Supported sampling: USB input: Maximum 192kHz / 24bit <br>Frequency Range: Audio In: 10Hz~100KHz(¡Â0.5dB) <br>USB In: 20Hz~20KHz(¡Â0.5dB) <br>Gain: +6/+17 dB <br>THD+N: 0.03% (1KHz)? <br>S/N: 110dB <br>Suitable Headphone Impedance: 16?~600? <br>Plug: US plug? <br>Color: Black <br>Size: 140 * 80 * 82mm / 5.51 * 3.14 * 3.22in? <br>Weight: 410g / 14.46oz? <br>Package Size: 20 * 18.6 * 11cm / 7.87 * 7.32 * 4.33in <br>Package Weight: 1032.5g/36.42oz <br><br><strong>Packing lists:</strong> <br>1 * XDuoo TA-01 Headphone Amplifier <br>1 * AC 100-240V Power Adapter <br>1 * A USB cable <br>1 * Compact Disk? <br>1 * English User Manual? <br>1 * USB Driver Installation Instruction
