Massive passive? – Au contraire. The icOn4 is petite but includes two Slagleformer magnetic volume controls whose taps are actuated in 40×1.5dB steps with super-fast Fet switches controlled by MCU firmware. There's ±7.5dB balance, mute, input selection, AV bypass, night mode and more via pre-paired Apple remote. In a far smaller casing, this machine takes over where the John Chapman passive left off when its designer stopped production due to overwhelming OEM work. The icOn4 can be configured for 3:2 or 4:1 RCA i/o upon order time.
