Global zero feedback circuit designed by Airtech (SeGeSTA configuration).
All stages of the amplifier are on independent and fully balanced boards, dual-mono configuration and discrete component circuits.
Power stage with 12 bipolar transistors per channel, filter capacity 81600uF per channel.
Oversized military resistors to minimize thermal distortion.
Audiograde components, microcontroller management.
Volume adjustment with four curves selectable according to the sensitivity of the speakers.
LED brightness adjustable on three modes.
Internal wiring with conductors in pure solid copper 7N OCC, golden copper output connectors.
Available in RR version with analog volume attenuation based on relays and resistors for a further improvement in every parameter of the sound performance.
Solid aluminum remote control supplied, finishes available: natural aluminum or satin black.
