The Lepai TA2020 mini Hi Fi audio amplifier is a compact power packed machine.
I could not believe the quality of the amplifier for the money I paid.
This must be the best £20 I have spent this year.
I bought it to play my Ipod through and boy was I impressed with the result.
This little baby really produces a clarity and is perfect for my Ipod.
I have also tried attaching it to my computer and Home cinema system and it's is perfect for this use.
The LED gives off a blue glow which radiates throughout the room , which I have heard upsets some people , but I fling this really cool
The tone controls are pathetic , but in all honesty you don't really need them as the
Sound is fantastic without using them.
If you are buying this for a realistic purpose then you will not be disappointed!
Your probably looking at this product with the same thought that came to mind when I first found this which is 'what is it' and 'what does it do?'..
Well basically this is a 'mini-amplifier' unit which can basically be used to create additional volume output whilst using and maintaining a low current, the unit operates at 12v DC which means it can be powered by a 12v car battery or AC/DC power converter attached to UK mains.
A little bit about why this product came in to my life..
After spending a few years on a GO-Kart project I had manage to assemble and produce a powered motor vehicle with all the mods and cons but to make it stand out it had to have some form of musical device attached, having spent a fair £1 or 2 already I realized my budget had to be adhered to. Having fitted two rear car speakers in my cart and already having a couple of 12v battery's attached I decided to grab an inverter and this little gadget to go with it.
It easily mounted to my kart with screws through the chassis slots on the edge of the unit and safely powered up all working fine. Result! The mini-amp doesn't provide enough volume to fulfill a festival or like but it does give a constant flow of 20 Watts output which enough to hear the music clearly given the circumstances. The unit connects easily to a mini-jack lead which allows the use of a smartphone, ipad or other musical device to be attached to the unit.
The unit has built in volume, bass and treble controls so you can tweak till your hearts content to get your perfect listening experience and of course the beauty is the price at just £20 you really cant go wrong. Touch Wood,, I haven't had any issues with my unit as of yet and my project is now complete thanks to the TA2020.
Thanks for reading.
The sound of this thing is so good that it may be better sounding than my high cost Yamaha AV receiver. I have on order a switch so that I can do rapid switching between both amplifiers to help with the listening tests. I have tried this little amp on three different set of speakers, two of which are 8 ohm and one set is 6 ohm. The 6 ohm set are my audiophile quality speakers; Norh 9.0 marble. The sound is fabulous with great weight to the bass, sparkling treble and clear midrange. The sound has great detail and resolution. The power is plenty for the sound levels I use. I'm never again going to think that high power ratings are important.
The build quality is adequate but certainly not high. No banana plug receptacles for example.
I actually bought the amp for use on the job (outdoors). It performed with high efficiency not completely draining my 12 amp hour 12 volt rechargeable battery car jumper setup I bought for it, in two days of use.
I love how it sounds at home on the Norh 9.0 marble speakers.
This model is the only one available with tone controls which is very important to me because some of the music I listen to has too much bass and occasionally too little.
If your unit has the light on but outputs no sound the problem could be with the supplied power adapter. The amp has an over voltage protection circuit that shuts off the amp when it receives too much voltage. The Ktec model KSAS0241200200D5 with 2 amp output works great.
For 24 punds this amp is a good deal. However, the included power supply is rather weak. In the specs section, it lists 12v 6a input (power supply included). I think most people reading that would expect the power supply to be rated for 6A. At most, the supplied adapter limits the output to 12 watts total. The $8 2A adapter from Parts Express bumps that to 24 watts total. That is still well below what the unit is capable of producing.
This incredibly neat little amplifier can transform almost anything with a headphone socket into an audio device capable of powering a pair of medium range hi-fi loudspeakers. It's powerful enough to fill our living room and also suitable for a car, caravan or boat (if you're lucky enough to have one). While maybe not quite up to the exacting standards of hi-fi purists, the sound quality seems amazingly good for such a low price.
I ordered this from Amazon for under £25 when one of the speaker channels on our Denon audio system (reviewed some time ago) suddenly stopped working. Everything appeared to be functioning apart from the final audio stage powering one of the speakers. The digital radio, cd player and USB etc. were all fine. Crucially, the headphone socket still worked and both speaker units were ok, so with a bit of lateral thinking it occurred to me there might be a simpler solution than attempting a repair to the Denon itself. There had to be something designed for use with MP3 players, phones, laptops or tablets, and indeed there was - in the form of the Lepai mini amp.
INSTALLATION, SETUP AND USABILITY
Connecting this to the headphone socket and speakers was simplicity itself, using the 3.5 mm stereo input jack and the spring terminal speaker connectors. The controls are equally straightforward. The tone controls can be bypassed, leaving only a volume control to adjust for optimum level. There's very little to go wrong.
Without going into too many technicalities, this device can be powered from a 12 volt DC (battery) supply or from the mains using the international adaptor supplied. This does seem to be a bit of an afterthought and somewhat cumbersome but it is at least serviceable - and note that some suppliers appear to sell these without any power adaptor. So beware!
Once connected, with tone controls bypassed and volume set, there's really nothing further to do. You just have to switch on manually.
The sound and power output may largely depend on the audio source and the quality/impedance of your speakers, but I remain impressed with both, especially considering the low price.
Don't ask me about signal-to-noise ratio, frequency response, channel separation or all that 'buff stuff' these days - what I will say is that this little amp produces a nice clean sound from a decent original source, especially if you select the direct mode that bypasses its bass/treble tone controls. I can't say I've noticed any distortion but for some further information, please see technical details reproduced below.
DESIGN AND CONSTRUCTION
This Chinese manufactured audio component is straightforward in design, functional and solidly constructed. The integrated circuit board, controls and sockets are enclosed in a light alloy body which feels reasonably robust and looks smart enough. The bright blue LED power indicator that surrounds the volume control might seem a bit intrusive to some but doesn't particularly bother me.
While this may be designed at least partly for in-car mounting, it sits well next to our existing home hi-fi units. It's certainly unobtrusive with a remarkably small footprint. (See dimensions below)
DOCUMENTATION AND HELP
In a nutshell: strictly limited! All you get with this is the briefest of user manuals, but to be fair that's probably all you'll need for this simple device. (Just as well, as the lepai.com website appears to be in Chinese!)
This workaround avoided a potentially expensive repair to our main hi-fi system. But, more to the point for this brief review, I've been so impressed with it that I'm considering buying more for use with our new TV and possibly with laptops and tablets. It could also be used with iPods and other devices.
My only minor quibble might be with its lack of remote control, though there are possibilities at least for remote control for on/off power switching.
