Product Details

Dayton Audio SA100 100W Subwoofer Plate Amplifier

Small but mighty! The Dayton Audio SA100 high performance subwoofer plate amp module packs big-amp features into a compact chassis that is ideal for installation into cabinets that can't accommodate bulky old-style amps. We made it small, but included everything that you need to connect the amp to your system and get maximum performance. Input/output connections are through your choice of either line level RCA connectors, or speaker level banana jacks. A stereo input signal is summed to mono and sent to the internal low pass crossover, which is selectable from 40 to 180 Hz; the input gain sensitivity is fully adjustable as well.

The SA100 also includes a phase reverse switch, which helps you to achieve the best acoustical match with the rest of your speakers. An Auto On/Off switch keeps the amp standing by, waiting for an input signal to turn it on. A large surface area heat sink is combined with internal overload, thermal, and short circuit protection so that you can expect years of reliable operation.

Specifications: • Measured power output: 75 watts RMS into 8 ohms @ 0.1% THD, 100 watts RMS into 4 ohms @ 0.2% THD • Signal to noise ratio: 90 dB (A-weighted) • Dimensions: 7-1/2" W x 8-11/16" H x 4-3/4" D • Enclosure cutout: 6-1/2" W x 7-1/2" H • Power requirements: 120 VAC, 60 Hz, 210 watts • Net weight: 7.6 lbs.

Rated 4 out of 5 by from Great product!I bought Dayton Audio SA100 to replace my dead PSB 5i. I am pleasantly surprised by great sound power and quality. Installation was easy and smooth. There are minor drawbacks:1) Speaker connectors were different sises and I have to replace them.2) There is loud click first time you power it.

Rated 5 out of 5 by from A Lot for the MoneyDon't let the power rating turn you off. The Dayton SA100 subwoofer amp is a serious performer. In the pictured build which I did (a downfiring subwoofer build) this combination produces very deep bass. It can get quite loud in my room, but my goal is deep accurate bass at normal listening levels.

Rated 5 out of 5 by from Perfect fit for my KLH subwooferRather than replacing my KLH subwoofer, I replaced my burnt out Plate Amplifier for this one. It fit perfectly down to the screw holes. So is it made by the same company who supplied the original one, who knows? All I know is that it saved me over $100 to buy another subwoofer.

Rated 1 out of 5 by from poor reliabilityThis is my third amp in three years, within warranty once, repaired and failed. Auto on feature burns out over and over. I hope this newer design is a better experience. Great when it powers up. I don't feel like building a new enclosure to fit a different amp at this point.

I see that the amp has left and right high level output making a nice 2.1 speaker system if I understand. There is little information for using the unit to power itself and external. About what power percentage go to each of the three outputs?

Asked by: jschex
The speaker level outputs are not powered, they are pass-throughs from the source amplifier driving this amp. Only the subwoofer output is powered.

Could I run this amp on a 8" sub on one channel AND a small transducer on the other at the same time?

Asked by: JeremyF
This is actually a mono amp and only has a single output channel.

I am in the UK and will probably purchase this amp in conjunction with 2 aura sh shakers.  I am concerned about mains voltage.  Will this amp operate at 230v? If not is there a 230v alternative or should I be looking at a 120v step down transformer?

Asked by: arknox
This particular amp requires a step down transformer in order to work on 230V. Our Yung SD100 or SD200 models have switchable input voltages so those might be another option for you.
