Four-stage Darlington circuit
Delivering a maximum output of 10W while employing the same four-stage Darlington configuration as A-1 ver.2 and A-2 ver.2. Even at low volumes, it demonstrates drive capability, producing air pressure changes.
Newly developed bias circuit
A newly developed bias circuit is adopted. S/N has been dramatically improved.
Enhanced pre-out function
- For the pre-out output, a powerful High mode is selectable, which outputs the loudspeaker output signal directly. A Low mode is also selectable, where the output is attenuated for easier handling.
- When selecting the pre-amplifier, a mode has been applied that outputs the loudspeaker output signal. A mode that cuts off the loudspeaker output is also selectable.
- The pre-out terminals feature both RCA and XLR connectors. The XLR terminals are configured as: [1] GND [2] HotA [3] Floating GND, enabling the noise-cancelling benefits inherent to balanced connections. Using SOULNOTE non-shielded balanced cables such as RBC-1 allows the pre-amplifier to deliver its maximum potential.
Direct mechanical grounding construction
By positioning a foot directly beneath the transformer, its vibration is released directly outside the chassis. Furthermore, employing a three-point support system via spike feet eliminates sound muddiness caused by chassis damping, achieving a vibrant and soulful sound.
