Fully differential balanced output headphone amplifier

The superiority of sound quality by balanced drive.

Fully differential amplifier
Adopts a fully differential circuit that can obtain high quality balanced output and unbalanced output at the same time.

Various headphone output
3 types of balanced output

Unbalanced output丂

High power output
Balanced output 3.5W/32ohms, Unbalanced output 1W/32ohms

Wideband all-stage direct-coupled DC amplifier丂DC to 250kHz

Headphone protection
Model10 has a protection circuit that protects expensive headphones.
The protection circuit disconnects the headphones under the following conditions.

Discrete configuration
Aiming for high sound quality, Model10 is composed of discrete parts that do not use operational amplifiers.
High quality parts are used.

High quality power supply
Model10 has a built-in high-performance power supply using a toroidal transformer.
Since no power adapter is used, Model10 can be installed in a neat manner.
Equipped with an IEC standard power connector, you can use your favorite power cable.

Sturdy chassis and high quality input terminals
The 8mm thick front panel and aluminum sash chassis provide stable operation and durability.
Gold-plated RCA terminals are used for the input terminals.

Technical explanation
Please look at Model10 technical description about an internal photograph, a circuit diagram, and detailed description.
