Gustard Audalytic HP70 Fully Balanced Discrete Headphone Amplifier, LME49720 Dual OP-Amps Class A Amp, 2xRCA /XLR Input 4.4mm Balanced /6.35mm Single-End Headphone /Rear XLR Preamplifier (Silver)

Features

• Fully Balanced Discrete Class A Amplifier: It utilizes 4 pairs of power transistors to ensure ample driving power and superior control. The use of discrete components offers greater flexibility, allowing for precise fine-tuning of each stage to achieve optimal performance
• This design approach also provides enhanced development potential. Distortion characteristics are more manageable, enabling the circuit architecture to deliver a wider range of sonic characteristics with greater versatility
• HP70 Headphone amplifier has 2 sets RCA and 1 set XLR Balanced Input, 4.4mm Balanced(TRS) and 6.35mm Single-Ended Output. Not only can it be used as a headphone amplifier, but also a preamplifier
• Preamp: The preamp utilizes two socketed LME49720 dual op-amps. Preamp output can be disabled for seamless switching between headphone and speaker
• Input Stage: Fully balanced topology: Single-ended to balanced conversion circuit allows RCA inputs to benefit from full balanced drive performance
• Multi-stage voltage regulation: Lower ripple noise and reduced interference for cleaner audio reproduction
• R-2R Relay Volume Control: Lossless precision adjustment with guaranteed channel matching across all 4 paths
• Built-in 30VA low-noise power supply. Also accepts an external 15-18V DC power input
