■The CP1H is an ideal headphone amplifier for audio enthusiasts, multimedia/streaming users, and sound engineers in live settings. In addition to general consumer headphones/earphones, it also supports reference headphones and low-sensitivity high-end headphones. It can drive headphones from 15Ω to 600Ω with ease, outputting a smooth and dynamic sound.

■ Overview
- A headphone amplifier with high versatility and connectivity
- Switchable 3-channel stereo input: XLR/6.3mm combo, RCA, 3.5mm mini jack
- Headphone output can be selected from 6.3mm standard jack/3.5mm mini jack
- Uses carefully selected electronic components to achieve clear, high-quality sound
- Smooth rotary control for precise volume adjustment

■ Professional-Quality Design
- The CP1H is a headphone amplifier with reliable quality and reliability, designed for everyone from audiophiles and audiophiles to professionals, including streaming, multimedia applications, and live sound environments.

■ Overwhelming Driving Power
- Supports a wide impedance range from 15Ω to 600Ω. It effortlessly drives not only listening headphones and earphones but also high-impedance, high-end headphones for professional use, achieving a sound that is both smooth and powerful.

■ Extremely Firm to the Original Sound
- Achieves a flat frequency response from 20Hz to 80kHz, minimizing sound quality changes due to impedance differences. With a high signal-to-noise ratio, it reproduces a clear and three-dimensional sound field without the noticeable noise from the power supply or circuitry.

■ The Appeal of the OTL Circuit
- Employs a classic OTL amplifier circuit. Despite its simple configuration, it extracts a natural and information-rich sound, boasting a level of perfection that surpasses its price range.
