The Headphone Amplifier v1 circuit design uses parallel amplifier stages to deliver enhanced power and reduced distortion. The Headphone Amplifier v1 has a clean and transparent sound, even at high gain levels and when driving low-impedance headphones.

The power and audio input connectors are screw terminals, allowing you to attach the necessary jacks without the need for soldering. Additionally, multiple Headphone Amplifier v1 units can be daisy-chained together to create a multi-channel headphone amp setup.

The soldering kit includes:

• 2 x 220u capacitor
• 2 x 110u capacitor
• 4 x 100u capacitor
• 1 x Pink LED 3mm
• 1 x Screw Terminal x2
• 1 x Screw Terminal x3
• 1 x Audio Jack 6.35mm Neutrik NMJ6HFD4
• 1 x 10k Resistor
• 4 x 4k7 Resistor
• 2 x 1k Resistor
• 2 x 2k2 Resistor
• 4 x 1R Resistor
• 1 x 10k Potentiometer Alps RK097
• 2 x NE5532

Electrical characteristics:

• Input Impedance: 20kΩ
• Current Draw: 10-20mA
• Gain: 0-10dB (customizable)
• Power Supply: 9 to 44VDC
