Key Features of Soulnote A0 V2 Integrated Amplifier
TO-220 type Transistor
For the output stage, TO-220 type transistors with low Cob and excellent high-frequency characteristics have been implemented in a single push-pull configuration. By deliberately limiting the maximum output to 10W, A-0 VER2 achieves uncompromising quality in a high-end design.
Four-stage Darlington Configuration
Although the maximum output is 10W, it employs the same four-stage Darlington configuration as flagship models, delivering precise and dynamic drive that lets you feel even the subtlest air-pressure changes at low listening levels.
A fully discrete, non-NFB Circuit
Aside from adding a selector and volume control, the A-0 VER2 maintains an extremely simple design—just like flagship A-3 and other top models.
A newly developed Bias Circuit
The S/N has been improved by the newly developed bias design.
Variety of Output as Preamplifier
The “pre-out” now offers a selectable High mode, which outputs the loudspeaker signal directly with full strength, as well as the Low mode, where the output is attenuated.
Enabling / Disabling Loudspeaker Output
When using the preamp function, an additional mode allows the loudspeaker output to remain active, while another mode disables the loudspeaker output.
RCA and XLR Connections for the Pre-out Terminals
The XLR terminals are configured as 1. GND, 2. Hot, 3. Floating GND.
