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's the actual wattage output at different impedances?
The PowerStage 100 Stereo delivers 100 watts per channel at 4 ohms (1% THD) and 50 watts per channel at 8 ohms, with continuous output power of 115W at 120VAC/60Hz. Choose your speaker impedance accordingly to match your monitor or reinforcement rig.
Can I use this for both stage monitors and studio monitoring?
Yes. The unit includes dual ¼-inch inputs and outputs for speakers, plus independent XLR balanced line outputs with switchable EQ, so you can run monitors and a studio reference feed simultaneously or switch between setups.
How does the 5-band EQ help me shape my mix?
The parametric EQ offers ±13.2–13.6 dB of cut or boost at five key frequencies: Bass (74 Hz), Low-Mid (389 Hz), Hi-Mid (1.55 kHz), Treble (4.6 kHz), and Presence (11.0 kHz), with independent switching for speaker and XLR outputs so you can dial different tones for each signal path.
Will this work outside the US?
Yes, the PowerStage 100 Stereo supports universal voltage input (100–240 VAC, 50/60 Hz), so it's ready to use anywhere in the world without an external converter.
How compact is it really?
At just 6¼ x 5 x 2½ inches and weighing minimal pounds, the PowerStage 100 Stereo fits into tight racks, wedges under a monitor wedge, or slides into a small road case—Class-D topology and 72% efficiency mean no excessive heat or bulk.
Do I pay sales tax on this order?
We collect sales tax only on orders shipped to California. Orders shipped to any other US state are charged $0 sales tax at checkout when you buy direct from our website. On this item that is roughly $42 less out the door than the same listed price at a national retailer or on a marketplace.
