MOS-FET switch is mounted on the speaker protection.
Generally, a mechanical relay is used for the power-amp
output for speaker protection.
E-600 replaces a mechanical relay with MOS-FET switch.
As a result, the reliability, Damping-factor and sound
quality is improved.
Super-heavy-gauge edgewise coil is chosen because the
DC-resistance is extremely low.
Output coil is essential for stable power amplifier
movement.
*On-resistance of MOS-FET used for E-600: 2.6mOHM
