Parasound ZC ZAmp VO.3 Integrated Amplifier

Small Amp, Big Personality

Drop the ZAmp v0.3 into your setup and small speakers wake up. Voices snap into focus, bass gets taut instead of boomy, and the whole presentation feels lively and effortless—even in tight spaces.

In a slim 1U chassis, it delivers 45 W x2 into 8 Ω (60 W x2 into 4 Ω) or 90 W bridged mono, using a fully discrete Class‑AB design with a toroidal transformer. Everyday integration is easy with 12 V trigger and audio‑sensing auto‑on, plus a front‑panel headphone jack and looping line outputs for flexible zones or bi‑amping.
