I couldn't believe my ears! This little amp has the sound of a full size amplifier. I connected a mini sound mixer,a turntable and a 5 disc CD player plus a pair of Bose 201 Series lll Speakers. WOW! This mini amp is a little Beast! PYLE built an amazing Mini Amplifier. I decided to return the little amplifier for a 75 watt per channel Pyle PCA3 Mini Amplifier for a little more power.

Seems cheaply made, but does its job. Not sure how long it will last, but it seems to stand up so far. The lack of quality in the build of the amp is a bit concerning for long term life but time will tell.

I bought this as a backup for a small PA. I attached it to an 8 ohm PA speaker and plugged in a dynamic mic. I found the output to be inadequate. I happen to have a small preamp, so I plugged the mic into the preamp, then into the Pyle amplifier. Now the output was acceptable. Since I already have the preamp, and the setup works, I will keep this amplifier.

I purchased this to drive 4 speakers in my dual Arcade 1up RasberryPi. Sound quality was quite good as far as I was concerned - keep in mind most audio im playing is from classic (retro) games. The speakers attached were a cheap set from an old RCA surround system and a set that came stock on the Arcade 1up systems. Bass and treble levels are noticeable when adjusted so those work on the amp. Sound level can go very high even though the speakers are of low quality. I have really tested the mic or "mp3" inputs but the composite L/R work perfectly. Definitely a great little amp for your DIY projects.

Como era para alimentar unas bocinas para mi habitación, la potencia es excelente, a pesar de de que las bocinas pueden más alcancen un nivel de volumen y nitidez de sonido muy bueno.Lo unico malo son los leds del potenciometro de control de volumen, por lo cual bajo mi responsabilidad y riesgo, abrí el amplificador y retire los leds de la placa base y listo!

Es excelente la verdad por el precio y por lo pequeño mis espectativas eran mucho menos y sorpresa que me lleve al conectarlo a mi laptop pues el sonido es genial no al nivel audiofilo pero si para un buen oído el bajo es profundo da mucho bajó por cierto con el botón bass sin embargó el sonido lo podemos equilibrar por medio del botón treible eso sí depende la fuente de música u el orígen de esta si es música de YouTube es digamos es un audio aceptable pero si el orígen es ,Spotify, Amazon música , radio online o música guardada en la compu se escuchará genial.

Great little receiver I used to power some outdoor speakers. Drilled holes in side wings to mount on wall. Works like a charm. Connected a Chromecast Audio DAC to it and stream to my back porch.Wish they would produce one with Chromecast/Spotify Connect built in.

La potencia me pareció excelente para su tamaño y precio. Sobre la fidelidad, hay quie decir que tiene controles de graves y agudos que no funcionan bien pues provocan distorsiones muy desagradables. Afortunadamente, ya que los fabricantes saben lo anterior, lo dotaron de un botón para eliminar esos controles y que la señal pase directamente. De ese modo la calidad del sonido es muy buena. SUGIERO ELIMINAR LOS CONTROLES QUE NO SIRVEN y de ese modo bajar aún más el precio, que ya es muy bueno

Hi-Fi meets D/C and it's love at first sound.It's rare to find low power in tandem with clarity in an amplifier.The punishment for purchasing entry grade equipment is often compromised, off-the-shelf components.This unit however, started life as a sound card chip that never managed universal adoption or notoriety and ended up seeing use by various manufacturers as a cost saving audio application. The PA200 is realistically 10 watts RMS/channel before it starts to lose headroom, but that translates into some serious volume levels with audible clarity and impeccable separation. If you are a connisuer and truly enjoy separating the musical nuances in a performance, then this chip's for you. Pye has made good effort packagng this Eco-amp friendly with hum/hiss-free stand-by and bass/treble controls which really come in handy for desktop applications.This is a super amp for a mere $30.00 folks! The benefits of running on 12 volts makes this unit so versatile in a host of environments. Low power consumtion, extremely small package, short output protected,light weight and minimal heat losses have filled a long overdue niche for a portable amplifier. It's so efficient it doesn't even need heat sinks but it delivers shimmering sibilance and amazingly controlled bass without wandering or runaway. The black extruded aluminum case should hold up well in mixed humidity use, where steel would make it look like your snowblower in a few years. A smart inclusion is a 1/4 standard mike jack on the rear and 2 RCA inputs and a 1/8 stereo on the front panel. Some users of these amps find there's not enough power or a lot of line noise but Pye has made their version with quality circuitry and connectors and mine is whisper quiet on Max connected to an iPad. The clarity of this amp easily reveals the lack of MP3's and AAC compared with CD.There are better sample rates amongst MP3's of course but any subtractive compression method in order to save storage, is dropping a lot of musical info. If I play the same music from the two different sources, the difference is dramatic. An iTunes download compared with a CD is far grainier and the bass smuggier, the composites of musical white noise is audibly truncated compared to the silky presentation from a CD. And once again, the level inputs are far higher and produce cleaner signal to noise levels at partial volume. Turntables can be notorious for rumble and hum but if your shielding is good,this amp will redefine all that old vinyl of yours, bringing out the best of analog sources. As an off-grid application this unit won't drain your deep cycle batteries for days...it's either Steppenwolf or eye-to-eye "really talking" on this two day, rained out trip. I have a Pioneer 7.1 system that would shut down the system by the time Frodo intercepts Gandalf on Bibo's birthday if hooked it to an inverter. 12 volt power packs come in a lot of different sizes to provide hours of decent amplification that you could strap to your body or facilitate a campfire group. The key is in it's flexibility and non fatiguing clarity. Nice job Pye, just don't get cheap on us "... That was Hammond's mistake".

The PFA 200 amplifier is a Class D (Class T) with BTL output which is non-inverting input to output with the “direct” button engaged (inverting with direct/tone switch in “tone”) with a RMS output power into 8 Ohms of about 4 watts. The PFA 200 is an example of the effect of aggressive output filtering to eliminate the switching noise on the Class D (Class T) output. The application note for this Class T IC warns against aggressive filtering. This amplifier provides a useful comparison to the Lepai 2020A+ which uses moderate output filtering. This filtering will be largely not noticed up to 2kH and noticed as a degradation of transients and frequency response above this point due to gradually decreasing response with frequency from this point to 20kHz where the response is down 34dB. The effect on musical transients will probably be noticed by critical listeners with good headphones or speakers. The effect on frequency response will be noticed by most. Subjectively I rate the overall effect of this amplifier as “good” since decrease in frequency response with frequency is a typical “room response” technique, as well as using a “loudness” curve when listening at low volume levels.There is significant distortion on the sine wave output from 2kHz to 8kHz. I assume this is an artifact of the digital processing and filtering. The waveform is still basically a sine wave but not smooth. This introduces varying levels of harmonic distortion. Since this is a BTL amplifier, slight crossover distortion is visible over most of the frequency spectrum due to slight mismatch of the Class T IC outputs. It is probably not audible. The slight phase distortion in the Bass region will probably not be noticed.Because of the aggressive output filtering I rate this amplifier as not as free from amplitude and phase distortion as the Lepai 2020A+. Subjectively the PFA 200 will have less “clarity”. The recovery of bass information is slightly better in the PFA 200 than the Lepai 2020A+.There is good volume action in the PFA 200 (not overly sensitive) with no potentiometer noise.With the tone control engaged the best 1kHz square wave presentation is with the Bass knob at minimum and the Treble knob at 50%. Under this condition the rise time is visibly degraded due to the output filtering, and the ringing of the waveform from the CBS 1 CD test disk signal is visibly filtered. This presentation is very similar to the presentation with the “direct” engaged except that the output gain with the “direct” engaged is greater. Subjectively, listening with the “tone” engaged imposes a “room response” on the output and will probably sound subjectively “good” or natural especially at low volume levels. Engaging the Tone button imposes increasing bass boost below 225 Hz combined with increasing cut at all frequencies above this point.With the direct button engaged, the response is basically flat from 17 Hz to 1kHz, with the phase error at 17 Hz of about 20 degrees and the phase error at 1kH about 8 degrees. The phase error becomes 90 degrees at about 8kHz. Above 1kHz there is a gradual decrease in frequency response of about (-)3dB at 10kHz and (-)34 dB at 20kHz (due to aggressive output filtering).Subjectively this means that you will probably notice a difference in musical transients and musical “sparkle”, but I judge the overall effect as “pleasing”.
