Conformal Coating
A conformal coating is a protective chemical coating to safeguard electronic circuits from harsh environments that may contain moisture or chemical contaminants. It provides a barrier to airborne contaminants from the operating environment, such as salt-spray, thus preventing corrosion.

Circuit Separation Construction
Separated circuit boards of the Pre-amp and Power-amp sections contribute to a reduction in radiation noise.

Large LPF Coil
The large LPF coil provides stable, high quality sound with no distortion even when playing at high volume.

Variable HPF & LPF
Incorporates a rotary type HPF and LPF which enables fine adjustment. Compared with fixed type switching, more precise sound adjustment is possible to match your preferences.
