Seymour Duncan PowerStage 100 Stereo, 120V
The PowerStage 100 Stereo is a compact Class-D power amplifier engineered for home studio monitoring, mixing referencing, and multi-destination routing. Its diminutive footprint—just over 6 inches wide—delivers serious output without consuming rack space, making it ideal for producers and engineers building flexible monitoring systems and submix chains in limited studio real estate.
Power Output & Studio Routing
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 feed both speaker loads and XLR balanced line outputs, allowing you to build stereo monitoring chains, distribute stems to reference systems, or maintain parallel processing paths without external routing hardware. 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 monitoring coloration. The switchable analog cabinet simulation lets you audition different speaker voicings or add character to submixes, while the 97.6 dB SNR on balanced outputs and 89.5 dB SNR on speaker outputs preserve detail and separation across both signal paths. Bandwidth extends to 15 Hz–22 kHz ±3 dB, capturing the full spectrum for critical mixing and mastering work.

Frequently Asked Questions
What does 100 watts per channel actually mean for my monitoring setup?
The PowerStage 100 delivers 100 watts per channel at 4 ohms impedance with less than 1% distortion, or 50 watts at 8 ohms; continuous output is 115W at 120VAC/60Hz. This is plenty of headroom for studio monitor speakers, in-ear wedges, or stage monitor cabinets without needing a larger, hotter amplifier.
Can I run both speaker and XLR outputs at the same time?
Yes. The PowerStage 100 has dual ¼-inch speaker outputs and XLR balanced line outputs, and you can independently switch the 5-band parametric EQ for each path, allowing you to send different EQ'd signals to speakers and XLR destinations simultaneously.
What makes the Class-D design better than traditional amplifier topologies?
Class-D topology delivers 72% power efficiency, meaning less heat output, lower power draw, and a smaller physical footprint without sacrificing clean amplification; combined with the 97.6 dB signal-to-noise ratio on balanced outputs, you get transparent, virtually noise-free monitoring in a genuinely compact package.
Will this amp work internationally or on different power standards?
Yes. The PowerStage 100 supports universal voltage from 100–240 VAC, 50/60 Hz, so it operates anywhere in the world without a power converter.
What frequencies does the parametric EQ cover?
The 5-band parametric EQ covers Bass (74 Hz), Low-Mid (389 Hz), Hi-Mid (1.55 kHz), Treble (4.6 kHz), and Presence (11.0 kHz), each with a range of ±13.2–13.6 dB, giving you surgical control across the entire spectrum; the switchable analog cabinet simulation adds further tone-shaping options.
