Clean Power You Can Feel

Drop the NC 2125v2 into your system and the whole presentation tightens up. Voices lock center‑stage, bass gets punchy (not boomy), and big moments hit with the kind of ease that turns casual listening into “just one more track.”

Designed for real‑world rigs, this compact 2U, Class‑AB workhorse delivers 150 W x2 into 8 Ω, 225 W x2 into 4 Ω, and bridges to 400 W mono. It’s THX Ultra2 certified, adds dual A/B speaker outputs with a front‑panel lockout, and is happy with tough loads thanks to 35 A peak current and a high‑current toroidal transformer. Integration is simple: Gold-plated RCA input jacks, 12 V trigger or audio‑sense auto‑on, and a switchable 20/40 Hz high‑pass filter to protect smaller speakers or squeeze more headroom.
