Feature
●Innovative circuit design, adopting DC 5-20V wide input working voltage, amplifier circuit can always operate at 26V high voltage and background noise indexes are excellent
●Adopts original TI-NE5532 classic opamp, transistor extended current circuit, using 1300mA large current output transistor that operates on Class A status, ultra low distortion, and the sound is warm and delicate. Plug-In Opamp Socket Design Upgrades a variety of optics amplifiers
●The U3 linear headphone amplifier features higher functionality than portable and incorporates unique circuitry for better sound quality. You can connect it to your PC or TV to watch movies, videos and games with more dynamic sound. Strong drive power makes it easy to drive most high impedance headphones such as: (HD580 / HD600 / HD650 / K701 / K702 / Q701 / DT880 / T70 / T90/SR225 / SR325 / RS1e)
●Note: This product does not come with a power adapter. Please use a power adapter that is at least 1A for DC5V, and for DC 12V, please use a power adapter that is above 0.5A
