Sonance SONAMP UA 2-125 DSP – Compact 2-Channel Amplifier

Product Overview

The Sonance SONAMP UA 2-125 DSP is an ultra-compact 2-channel amplifier for local zone audio, offering both analog and digital inputs with built-in DSP in a chassis small enough to fit inside a structured wiring can or outdoor enclosure. It is intended for integrators who need a flexible, low-profile amplifier for a single room or zone without HDMI eARC connectivity. The combination of digital and analog inputs makes it adaptable to a range of source equipment.

Product Description

The UA 2-125 DSP outputs 125W per channel at 8 or 4 ohms, with a Power Sharing Mode available for 250W to a single zone when higher output is needed. This Sonance amplifier accepts analog RCA inputs alongside Optical TOSLINK and Coaxial S/PDIF digital inputs, both supporting 2-channel PCM audio, with RCA outputs offering volume tracking for downstream equipment. Setup and DSP configuration are handled through the SonARC mobile app, which also manages Audio Sense auto-on and learning IR control functions. The chassis uses the same industry-standard 20mm T-slot mounting as other SONAMP local zone amplifiers, with included surface brackets for flexible placement. It is a good match for in-ceiling speakers in a single zone where a digital source, such as a streaming device or media player, needs to be connected without an HDMI connection.
