Description
Equipped with C3g
Equipped with the ultra-reliable C3g developed by Deutsche Telekom for telephone repeaters. The thin grid lines and large distance between electrodes enable high linearity amplification. The C3g is soldered directly onto the board to reduce noise at the contact point.
Proprietary transformers
Proprietary transformers are used for the input and output. The transformer is an important part that influences the performance of distortion, S/N ratio and input/output impedance. Therefore, the core material, wire material, winding thickness, and winding ratio are meticulously designed and manufactured.
Power supply for each left and right
Independent power supplies deliver power to the left and right channels as well as control circuits. Using all of the characteristics of the components together, we are able to preserve silence.
Resistance switching ladder attenuator
In a variable resistor that slides on a resistor, noise is generated by a point-contact diode, which can be a source of distortion. This unit is a crossbar twin structure. A gold and platinum contact relay switches the resistance and attenuates from 0 dB to -60 dB.
