Frequently Asked Questions
It's functional, but lacks the sophisticated parameter control of higher-end duckers; it’s a more basic, ‘on/off’ type of reduction.
No, the DU-30B does not provide phantom power, so it’s unsuitable for condenser microphones requiring 48V.
It leans towards clean, but there's a subtle warmth – not a colored preamp, but not entirely sterile either.
