FEATURES
Green Class A
Plug in your headphones and Amp mini will deliver optimal performance. It smartly shifts from Voltage mode to Current mode to match your headphones’ sensitivity and impedance. This maintains excellent Class A linearity, while minimizing heat — a real breakthrough in sound quality and energy savings!
Variable Tube Drive
Class A is so squeaky-clean, it will satisfy the hard-core fans of sonic purity. But watch what happens when you add some old-timey tube warmth to your favorite tunes! The Drive dial delivers the slick growl without raising the volume. Crank it up and don’t be surprised if you feel transported back in time!
8W of Balanced power
Up to 8W of output power to drive all planar headphones. Pitch-black noise floor. Super-low audio distortion of 0.001% THD. Balanced and unbalanced headphone outputs. 1/4″ single-ended and 4.4 mm Pentaconn output jacks to accommodate any headphones on Earth.
Fly-by-Wire Controls
The large volume knob delivers a smooth, satisfying feel thanks to the internal hydraulic pressure-absorbing system. The channel balance will stay the same at any volume level. Everything inside Amp mini is microprocessor-controlled (fly-by-wire), meaning silent adjustments and precise control.
Tube Rolling
Enjoy High-Res content as you work at your desk! Amp mini™ stacks with our DAC mini™, as well as Mac Mini™ and Mac Studio™ from Apple™, creating a slick desktop system your friends will envy. Ready to customize? Roll the tubes using either 12V or 6V models, such as 12AX7, 6BC8, etc.
Green Class A™ is an adaptive amplifier technology that delivers optimal amount of clean power to your headphones. Sensitive headphones require less energy and less heat. All you do is turn a knob to indicate your headphones’ sensitivity. Amp mini will self-adjust to your headphones, saving power whenever possible. With sensitive headphones the amp will actually run cooler, while still delivering stellar performance. This is not possible with traditional Class A designs, which waste a lot of energy no matter what headphones you use.
Green Class A puts you in control of the amplifier’s power consumption, by letting you correctly identify your headphones. The amp does the rest, as it configures itself for lowest environmental impact. This is a real breakthrough in sound quality and energy savings. Enjoy your music even more, knowing you are helping to make the world a cooler place!

Please be careful with Balanced Armature, In-Ear and sensitive Dynamic headphones.
The HP Sensitivity control is similar to a gain range knob. It works in tandem with the volume control, but it does more under the hood. The end result of turning HP Sensitivity dial is louder or softer audio, but it comes from reconfiguring the power delivery infrastructure for optimal energy use.
Think of it this way: The volume dial deals with audio volume. The HP sensitivity dial deals with energy consumption. It changes the amount of power delivered to the Class A stage to match the needs of your headphones and optimize heat dissipation. It’s like a gearbox on a race car. And the Volume knob is like a gas pedal. Both contribute to how fast the car is going, but they do it differently.
Headphones’ sensitivity depends on the transducer type and typically ranges from 115dB (efficient) to 85 dB (inefficient). This data is available on the manufacturer’s website or in the user manual for your headphones.
Using the sensitivity value for your headphones, adjust Amp mini’s HP Sensitivity dial to match. That calibrates it for optimal performance. Amp mini will then deliver correct amount of energy to the headphone jack and manage the amount of generated heat. Traditional Class A amplifiers don’t care about the headphones used and always run at maximum power. Amp mini’s Green Class A technology can adjust to your headphones in order to lower the heat and save energy.
A note of caution. With the total amount of 8W of available power, you need to exercise care in using Amp mini with sensitive headphones, and especially with in-ear-monitor headphones (IEMs). If Sensitivity is set improperly, it can cause very high output levels, which are bad for your hearing. High output levels can also damage some IEMs.
Setting the HP Sensitivity dial to 115 dB will result in the lowest power. That’s the safest setting and a good place to start. That’s also why the HP Sensitivity knob appears to have the numbers going “backwards” — to match the volume knob. As you turn the dial clockwise, power goes up, on both dials.
Always start the amp with the Volume knob completely down (set to MIN) and then gradually turn it up until sound is heard. Never start the amp at maximum volume AND low sensitivity, such as 85 dB. At those settings Amp mini will deliver highest amounts of power, which is very dangerous to your headphones and to your hearing. Amp mini was designed for using planar headphones, which are notoriously hard-to-drive and require extra power. Use extreme caution when using IEMs with Amp mini. Think of it as a powerful race car. It can rip things apart of not used correctly.

Let’s face it — Class A is a controversial technology in a sustainable world. For years, Class A was considered the best option because it delivers the lowest audio distortion. But this benefit comes at the expense of wasted energy. Traditional Class A amps produce a lot of heat, even when no music is playing. These amps continuously waste power and the extra heat is not good for the environment. Centrance wanted to improve on this and invented an alternative. We call it Green Class A™.
