Product Details

Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output

Lepai's LP-168AH 2.1 amplifier is the perfect computer partner—it provides up to 40 watts of power output to stereo speakers, in combination with a dedicated subwoofer output capable of up to 68 watts of amplifier output. To connect a subwoofer simply hook them up to either the left pair or right pair of bottom row spring terminals; both are the same because they are wired in parallel.

Bass, treble, and volume controls on the front of the amplifier let you adjust your music for the best possible sound from your speakers. The discrete subwoofer output is controlled separately from the stereo output, with controls for level adjustment and crossover adjustment found on the amplifier's face.

Audio source connectivity is provided via a front-mounted stereo 3.5 mm jack, or a stereo pair of RCA jacks on the rear of the amplifier. A rear-mounted USB port enables charging of devices such as smartphones and MP3 players. The wide input voltage range of 9 to 14.4 VDC allows the LP-168AH to be used in automotive or mobile applications. A 12VDC, 3A power supply is included.

Specifications: • Stereo power output: 2 x 40W max (power output dependent upon power supply) • Subwoofer power output: 1 x 68W max (power output dependent upon power supply) • Power requirements: 9 to 14.4 VDC, 3A • DC power input jack: 2.1 mm x 5.5 mm • Bass and treble control • Stable down to 2 ohms • Minimum THD: <1% • Signal-to-noise ratio: >80 dB • Frequency response: 20-20,000 Hz • Adjustable subwoofer crossover: 50-200 Hz • Dimensions (including mounting flange): 7" W x 4" L x 1-3/4" H.

Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output
Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output is rated 4.0351 out of 5 by 57.
Rated 4 out of 5 by from Monsoon replacement.So I have a few of the trouble prone Monsoon computer plainer systems. The amp died on one of them and I went through the options. Add a new sub, build a new system around the satellites and a bunch of others. After some thought I thought I would start with this and go from there. Gutted the powered sub and sealed it back up adding some fill to it. Used a passive HP crossover to the plainer speakers and hooked the mess up to this amp.After a little tweaking it is OK. I think there was some electronic crossover tweaks in the original amp but I am happy. Going to add a better PS but at least I have my planers back for the computer. Yes I control the volume with the computer but after setting it up it is not bad. The amp will produce plenty of volume for what I am using it for.

Rated 2 out of 5 by from Okay - but nothing spectacularI knew when buying this that the price was low enough to not expect anything spectacular. The output for the stereo speakers is fine. Powerful enough and of acceptable sound quality to make my 6.5" MB Quarts in a boombox sound nice.The subwoofer output is another story. It makes an extremely distorted sound at all volume levels. I checked by reversing wiring such that the subwoofer is driven off of one of the stereo channels, and the sound is fine (so it is not the driver).At this point, the subwoofer output is pretty much useless. The distortion is so bad that I hear it over the stereo channels. I'm looking for another alternative now.

Rated 4 out of 5 by from A good amp for a 2.1 applicationI built a 2.1 set of speakers for my daughter and I was looking for a small amp until she buys (can afford!) a good 5.1 receiver... So I found the Lepai LP-168HA 2.1 mini amp. A decent amplifier, runs barely warm after hours of testing. Not a five star because of the master volume not a master... Found it needs more juice so I replaced the 3A 12VDC unit with a 5A for better low end support. This unit feeds a set of two FE83 as full range left & right with a Peerless SDS-135F25CP08-08 5 1/4inch as the sub. The daughter has this in her apartment bedroom and is happy with the 2.1 setup. Good dynamics with defined voice and wide range. Not a high power application but enough for the occasional rock and roll.

Rated 2 out of 5 by from MisleadingThis amp doesn't come close to the wattage claimed.The distortion level is extremely high at upper volume range.It only delivers 7 or 8 watts before it starts distorting.So if you can live with distortion or low wattage, go for it.Other wise, save up more money, and buy something of better quality.

Rated 5 out of 5 by from Jack it up to 12V-5A and it's a winnerWith its included 3A power supply, the Lepai LP-168HA is an adequate little desktop amp. And, considering you bought it for the price of a Happy Meal - and momentarily disregarding this little amp's quirks - adequate is okay. But swap out Lepai's 3A power supply with a 5A number, and you can say goodbye to adequate and say hello to something completely unexpected. Loud.No, it won't be molar-rattling loud. But it will be loud. Loud enough that you'll want to ratchet the volume down on the iPad (or whatever) and set the amp to "5" or so before daring to flip the switch. Forget, and there's a good chance the neighbors will come knocking. And with a separate volume control for the sub, forgetting comes easy. Which is one of this amp's initially annoying little quirks.The master "volume" knob doesn't do sub. The sub control is off to the left, next to the microscopic 50Hz to 200Hz "X-Over" dial-ette. This bipolar configuration and its particle-sized knobs will eventually grow on you and, oddly, begin to make some sort of sense. Until it's 5 a.m., the family's asleep and you once again forget. Just remind them what you paid for the thing.As to the important stuff, the amp out-performs just about anything else you won't find at this price point. The sound is remarkably clear. And those two otherwise choosy 80 watt yard sale GC Electronics bookshelf speakers seem to like the thing. It even arouses the 200 watt JBL sub (especially when it's 5 a.m. and you once again forgot to crank down the mini-dials). And while the mileage seems to vary on this one, the cross-over works as advertised. The USB charger doesn't, but who cares? Either does the "manual," unless you're fluent in Mandarin. But again, who cares?A final note for those who still aren't convinced. I rigged this amp to temporarily power the 16 ohm Alnico "tweeter" that feeds the upper rotary horns on a recently overhauled vintage Leslie organ speaker cabinet. It somehow managed to keep up with the 300 watt bass speaker bolted-on down below. And it did it without a whimper, remaining at room temperature despite having to overcome all those 60-year-old ohms. Score one for our friends in the People's Republic.

Lepai LP-168HA 2.1 2x40W Mini Amplifier + 1x68W Sub Output

For those who own both this amp and the Lepai LP-2020A+... How does this amp compare? It is rated at twice the watts per channel, but is it significantly louder? Is the sound as good as the LP-2020A+?

Asked by: billbill
I have 2 of these amps, one works fine and the other one has a bad sub output. it has a distorted crackling sound. the Lepai LP-2020A+ is much louder and a little better sound quality than these

Can a powered subwoofer be connected to this amp or is it meant for a passive sub? If yes, would it reduce the amount of watts going to the right and left speakers?

Asked by: billbill
This can be connected to a powered subwoofer as long as the sub has speaker level inputs and outputs. It will have no effect on the output to the other speakers.

I found that the sub out only gets signal from the left channel & that the bass from the right channel is discarded.  Is this by design or is my amp malfunctioning? I tested by plugging headphones into my source and got bass in both channels.

Asked by: wdhays
This is not the case. The sub output is a combined signal of both the left and right channel. It can favor one side due to inconsistencies in the resistor values that combine the signals on the input. They need to be perfectly matched for it to be balanced. I have several of these amplifiers and between the 3 that I have there are 2 different board designs. The first one that I had perfectly matched values and the second two needed to be replaced to get a balanced input.

How would I hook this amplifier up to my computer? Is that an Aux in on the front of this amp? If yes, Can I run a 3.5mm cable from the sound card to this amp? Also, would this work OK with Dayton B652's since they are 6 ohm speakers?

Asked by: billbill
This amp has line level RCA's on the back so you can use a cable thats in the link below to connect for a computers output. Yes this will work fine with B652's.
