Sonance SONAMP 275 SE 2-Ch Power Amplifier DSP BBE SAT Sound Enhancement
The Sonance SONAMP 275 SE is a 2-channel DSP power amplifier designed for whole-home and distributed audio systems. It features a factory-installed BBE SAT (Sonic Attitude Technology) module and a high-current amplifier topology capable of driving loads as low as 2.66 ohms, making it well suited for in-wall speaker installations and multi-room audio setups. Introduced in 2006 with an original MSRP of $600.

Applications
The SONAMP 275 SE is part of Sonance's line of architectural audio amplifiers, built for permanent or semi-permanent installation in residential and light-commercial distributed audio systems. It is commonly used to drive in-wall or in-ceiling speakers in whole-home audio setups, where the amplifier is installed in an equipment rack or AV closet and feeds speakers throughout the listening area. The defeatable high-pass filter is specifically designed to protect passive in-wall volume controls from over-excursion at low frequencies — a practical feature in multi-room installations where passive volume controls are used at each zone. The BBE SAT processing module provides psychoacoustic enhancement intended to improve perceived clarity and definition in distributed speaker systems, which often deal with longer cable runs and varied room acoustics. Auto-on signal sensing allows the unit to power up automatically when a source signal is detected, a convenience common in background-music and whole-home audio installations.
This Sonance SONAMP 275 SE 2-channel DSP power amplifier has been tested and confirmed in working order at our facility. We fed line-level audio into the balanced input terminal block on the rear panel and connected speakers to the banana connector speaker outputs — the unit produced clean audio on both channels. Note that output volume is controlled from the source, not the amplifier itself. The unit is in good used cosmetic condition consistent with normal wear on pre-owned electronics.
