Seymour Duncan PowerStage 100 Stereo, 120V

Seymour Duncan PowerStage 100 Stereo, 120V

The PowerStage 100 Stereo is a compact Class-D power amplifier built for gigging musicians, sound engineers, and venue operators who need serious amplification in a footprint that fits in a gig bag or monitor rig. At just over 6 inches wide, it delivers 100 watts per channel without eating up valuable stage or rack real estate, making it the go-to choice for stereo monitor mixes, powered wedge cabinets, or split-signal setups at small-to-medium venues and studios.

Power Output & Connectivity

This unit delivers 100 watts per channel at 4 ohms/1% THD (or 50 watts at 8 ohms), with continuous output power of 115W at 120VAC/60Hz. The dual ¼-inch inputs and outputs accommodate both speaker loads and XLR balanced line outputs, allowing you to run stereo monitoring rigs or split signals to multiple destinations simultaneously. Universal voltage support from 100–240 VAC, 50/60 Hz ensures operation anywhere in the world.

Tone Shaping & Signal Management

A comprehensive 5-band parametric EQ with individual switching for speaker and XLR outputs gives you surgical control over your signal path. The switchable analog cabinet simulation lets you dial in the exact character you need for your setup, while the 97.6 dB SNR on balanced outputs and 89.5 dB SNR on speaker outputs ensure a clean, quiet signal across both paths with minimal noise floor. Bandwidth extends to 15 Hz–22 kHz ±3 dB, capturing the full spectrum your source material and monitor mix demand.
