Question: Can I run an RCA cord from my TV to this amp?  The input/output schematic does not show a TV.
Document: I just got the Pyle PTAU45 amp. This is an upgrade from the Lepai LP2020A+.The Pyle amp is built more solid, and the knobs are of a higher quality. There are various inputs; the typical headphone and MP3 jacks, 3 sets of RCA stereo inputs, even RCA output(record)and a mike input with mixing. The one disappointment is the USB input. It does work, but emits a constant low-level buzzing while playing.
The compact Pyle amplifier works perfectly to amplify input from computer, iPods, and TV out to 2 floorstanding speakers.I didn't need another component sized "receiver" when all I needed was something the size of an external HD/case.This perfectly meets our needs and provides good, clean power to a pair of floorstanding speakers.The only possible drawback is the BRIGHT blue LEDs that show left & right channel activity. May have to desolder those.
I docked 1 star on the overall rating because of the LED light show. The power output BLUE LEDs are REALLY bright and SUPER annoying; currently I simply place a small item to block the lights, but I will most likely open the unit up and disconnect the LEDs. I knew ahead of time that the amp doesn't come with a remote control, but it would definitely be a nice feature to have. I highly recommend this amp.
I needed this amp to power one speaker from my TV audio output. It worked okay other than the very bright flashing twin set of red LEDs. Even duct tape wouldn't block them enough and it was quite annoying while watching TV. Also this has no volume remote control which I now think is necessary for my situation.
20W per channel is really not enough to drive any decent speakers. That's right, the real number is 2x20w not 2x120w as advertised here. I was going to use it with 2 sony speakers for an entry level stereo home theater with the TV as the source but it doesn't deliver enough power for a decent volume. Also there is noise when using a USB stick to play music. Really not even the headphones output is any good, I get better audio quality from the ipod directly than through this amp.
This small amp is great for TV/digital radio applications. Great power and sound. Not powerful enough for phono output.
First one did not work out of the box. Insanely bright , cornea burning bright L/R out put LED lights showed output, but nothing out of spekers. Amazon return was super easy. Second one arrived quickly, worked perfectly out of the box. Both boxes had ORIGINAL tape on outside but, first one was missing baggie on cord, bag on amp was not folded shut like second one, also noticeable oily/chemical smell missing from first one.
This amp is what it is. Nothing fancy, but it doesn't pretend to be. It's great as a accessory amp for MP3 players, flat screen TV, etc. I like having multiple input options and separate bass/treble controls. It's not for audiophiles, but come on, for ~$80, one wouldn't expect it to be. Five stars if it had a remote control. Plenty of power for a smaller area.
This Pyle amp seems to be of good quality, and PYLE is among the very few "low-end" amp manufacturers that provide a USB option. I would love to also have flash card input, such as for Secure Digital (SD) input, but there are very few manufacturers that provide that option at this time.Update: Nov 12, 2011- Very nice amp. I use it for hours each day to power my TV speakers, and for about an  hour per day to listen to music.
This was extremely stupid of Pyle to use such a cheap connector. I split each strand of 16 gauge wire in half (about 20 to 24 gauge wire thickness) and cut off the excess. This seems to fix the popping out issue. As for the blue output LED lights, yes they are very bright and will provide a free blinding light show, but nothing black electrical tape can't fix.
Answer: All 3 inputs are RCA, just pick one :) Just because it says "CD" or "Aux" doesn't specifically mean you must use that device, RCA is RCA. However, I wouldn't recommend purchasing it. Mine died (non smoking house, didn't overheat or push it too far) within 1 month of use. I decided to go with the Dayton Audio APA150, which has been a workhorse since day 1 with no issues and much better consumer ratings than this Pyle of junk. Happy hunting.
