XZ-U606U Ultra HIFI High Current Portable 4.4mm Fully Balanced Headphone Amplifier Phone Preamplifier

Introduction: XZ-U606U Ultra portable fully balanced headphone amplifier, small size large trust, real balanced input and output interface. The product adopts a truly fully balanced architecture amplifier circuit design, combined with innovative circuit design. The amplifier circuit always operates at a high voltage of 24V, with excellent bottom noise indicators, making it difficult for you to distinguish whether the machine is turned on or not. The noise during startup is like shutting down. It has a wide frequency response range, excellent transient response, excellent purity and transparency, and good dynamic range. Pure analog amplification circuit and pure analog control are designed to provide the most realistic reproduction of the simulated taste of music. The sound field, positioning, and air feel details are super first-class! Enough power to easily drive various commonly used earphones in the market, ranging from 18 to 600 ohms. The XZ-U606U Ultra introduces a 4.4mm balanced headphone jack, and the left and right channels are driven by two independent amplification circuits to avoid crosstalk. Provide higher signal-to-noise ratio, better sound separation, and bring greater thrust. To achieve balanced output, it is necessary to use a 4.4mm balanced input pair recording cable and headphones that support a 4.4mm balanced interface.
