*Tips
- Do not cover newspapers, tablecloths, curtains, etc. on the machine, as this may prevent heat dissipation. If the temperature inside the machine is too high, it may cause a fire, damage the machine, or cause personal injury.When using switches, knobs or cables, do not use excessive force.
- Only use the voltage specified by this machine. Using a voltage higher than the specified value is dangerous and may cause fire, damage to the unit, or personal injury.
- Do not attempt to modify or repair this unit by yourself. If you need any service, please contact the MUSICIAN after-sales team through the official website.
- If you plan not to use the machine for a long time, disconnect the power cord from the AC wall outlet. To strengthen the protection of this product, unplug the power cord from the wall outlet during lightning, or when no one is managing it, and when not using it for along time. This will prevent the product from being damaged during lightning and power grid surges.

Technical Highlights Fully Balanced Class A Headphone Amplifier
Andromeda headphone amplifier is a matching entry-level headphone amplifier
launched by MUSICIAN for Pegasus DAC. It also uses the same good technology of
pegasus DAC-automatic switching of power supply voltage to quickly restore the
ultra-low noise linear power supply.
Andromeda and Pegasus have the same chassis width and depth, no matter in size
or sound quality, they can match very well.
The circuit design of the whole machine adheres to the shortest audio path,
and the sound quality is the main concept.
The power supply has been continuously optimized and improved. The O-type
single crystal copper transformer used can provide higher dynamic range and
sound performance. The built-in aluminum heat sink can achieve heat
dissipation and make the operation more stable.
It can easily drive any headphones with an impedance of 150-6000, and can
continuously output 350mW of undistorted power to a 600Q load, meeting the
needs of difficult—to—drive headphones.
