Bit Trade One Current Feedback Type Headphone Amplifier Assembly Kit

Item Descriptions:

It is a current feedback type portable headphone amplifier that maximizes the performance of headphones.

Characteristic

.Current feedback amplifier circuit

Express fidelity of bass and treble without being influenced by impedance fluctuation of headphone

· Optimization by resistance

Optimization for all headphones.

By changing the adjustment resistor, we optimize for headphones using the current feedback circuit and maximize the performance of the headphones.

· Two evolved technologies

OCL (Output Capacitor-less) technology: No output coupling capacitors are required for power amplifier output.

Bass performance is greatly improved and pop noise is also reduced.

LIFE (Load Impedance Independent Engine) technology: faithfully reproduced from bass to treble without being influenced by headphone impedance change.

It will be a special commentary.

A thin aluminum case outstanding for portability is included.

The thickness is just 2 cm, the kit's completed weight is also 147 g, which is super lightweight.

By adjusting according to the headphones to be used, it is possible to maximize the performance of the current feedback system.

Adjustment is done by changing metal film resistance.

(Adjustment resistor is socket type)

It is possible to produce it with only a simple work using a soldering iron.
