Dayton Audio APA150 150W Stereo / Bridgeable Amplifier
The Only Amplifier You'll Ever Need
Amplifiers today need to be multi-faceted to keep up with the task at hand, and versatility is the foundation upon which the Dayton Audio APA150 is built. When configured in stereo mode, 75 watts of amplification is provided to a pair of speakers for stereo or surround playback. Select bridge-mono mode and the APA150 is ready to power a center channel speaker, or a subwoofer/tactile transducer with 150 watts when used with the on-board low pass filter. Full-range line-level outputs allow for daisy chaining amplifiers for a multi-room whole house audio system or for bi-amp applications. The APA150's smaller chassis consumes less space than conventional amplifiers, making placement options virtually limitless.
Standard features of the APA150 include high current, discrete power transistors (used in premium amp designs), a hefty toroidal power supply transformer, low-noise forced air cooling, and complete protection against electrical shorting and thermal overload.
The APA150 was designed for heavy duty use, including subwoofers. An 18dB/Oct low-pass filter can be set from 50Hz to 150Hz or run it in full range for higher powered speakers!
The APA150 has the ability to bridge the stereo outputs to combine both channels for extra power with a single mono/stereo switch.
When the APA150 detects signal at its input, it can automatically turn itself on. Once the music has stopped playing, the APA150 will turn itself off automatically to save power. No fuss and no more reaching over your expensive equipment!

This amp is a mostly unknown "sleeper" in the audio enthusiast, world, but sells-out quickly when new stock arrives ... it basically has no measurable self-noise, a better than decent slew-rate amp; transient response time amp; i personally enjoy it's capability to instantly switch it to the mono-bridge, mode amp; also utilizing it as subwoofer amp, using it's onboard pass-filter

I love this amp. I have one powering a pair of deck speakers fed by a Chromecast audio device. I bought another to power in-ceiling Klipsch speakers, again fed by a Chromecast. It feels high quality and provides solid, clean, crisp sound without a bunch of unnecessary driving circuitry.

This is a great amp for the price. I'm using it to drive a 12" Velodyne (formerly) powered subwoofer whose amp had given up the ghost. I like that you can adjust the frequency of cut-off. It really thumps, too, as good as the original. Amp has an auto-on which is nice. The LED on it is searingly bright, but I keep the amp in the closet so doesn't matter much. All in all, a great amp for the money.

Owned this amp for 10 years and use it to power Dayton Audio IO655WT 6-1/2" 2-Way 70w outdoor Speakers. Clean sound.
