BehringerMiniAmp AMP800 4-channel Headphone Amplifier

Funciona perfectamente. Tengo 3 años usándolo y nunca me ha dado problemas.

I can't help but be amazed with what you can buy these days for so little money and just have a great time listening to. The fact that the Behringer AMP800 has two independent stereo inputs was important to me because I have two PCs in my setup. The output power is more than adequate. The Sennheiser Headphones in the HD 515 and 595 I recently just bought are 50 ohms and are driven so easily by this amp that the input lights on the amp barely even come on at loud volumes. Out of the box for PC use you will need some adapters. It is marketed for pro use as it uses 1/4" mono connectors for the inputs and the output to separate amp. (It can be a second Behringer AMP800 or a different type of amp altogether as I'll explain) You can order the RCA female to 1/4" mono adapters right here at Amazon.com or get them at a Radioshack. For the headphone outputs we have 1/4" stereo connections and the same applies for 3.5mm stereo female to 1/4 stereo adapters. They are also readily available.I'll describe exactly how I have it connected and for what purpose before I discuss the actual sound quality. It really is a super versatile piece of equipment.On input A I have my PC connected to the Behringer AMP800 from an older Soundblaster X-Fi Extreme Music. I'm running a 3.5mm stereo cable from the left/right/main output that breaks out into two RCA cables with RCA female to 1/4" mono adapters on the end connected to input A left and right. I'm running two 1/4" to RCA adapters connected to the left and right output running a stereo RCA cable to my Gemini XG 3001 stereo amp. So in short you can run headphones from the AMP800 with input A and when you turn off the AMP800 you can run your stereo power amp to power speakers when not using headphones for the same source. Pretty awesome stuff right there. That capability is only possible on input A.On input B I have my other PC connected using a USB Sound Card from Sabrent that uses a C-Media chipset that offers 24 bit 96khz audio in Windows 7. It is a simple connection of a 3.5mm to stereo RCA cable and two female RCA to 1/4" mono adapters. To activate input B you press button on the headphone channel you are using until the green light comes on and turn up the volume dial for input B. Its as simple as that. Now how does it sound with my gear...Compared to the output of various receivers and the headphone output of the sound cards I'm using that don't have a built-in headphone amp the sound is really good. I've tried a lot of combos including the Soundblaster Live 24 bit, Soundblaster Xtreme Audio, Soundblaster X-Fi Surround USB, Asus Xonar DS, and various C-Media based USB sound cards of which I will review separately. You have to try different things before you understand the sound signature of an amp and can judge its performance. The AMP 800 does a great job keeping mids and highs very pronounced while having good bass output and provides absolutely no audible noise. It really has a very good soundstage with my Sennheiser HD 515s and even more so with the Sennheiser HD 595s. The 515s can be harsher and the 595s are more neutral and I can listen for hours on end with this amp. I also bought the FiiO E9 and a Soundblaster X-Fi HD USB and that combo aint that much better than this. For the price the Behringer AMP800 is a great start to headphone bliss with headphones that are reasonably priced and reasonably easy to drive. To call this amp versatile is an understatement as I did not even discuss the uses for musicians.

I bought this little amp to use with my laptop PC, so I could connect it to PC speakers, headphones, and my surround sound system. It could use a little more gain, but at the maximum settings it's just barely enough. The output from the PC is too low a level to work with my surroundsound system. Also I have a ground loop, which causes hum and picks up RF interference. The best feature of this amp is the differential inputs, which should (theoretically) eliminate the hum and noise problems. I thought it would be a problem that the differential input requires the use of 2 stereo 1/4" plugs, one for right and one for left, with the tip and ring being the differential signal! In all my 40 years of working with audiovisual and musical equipment, I've never seen a plug wired this way. Behringer says they don't know where I can find one either, so I tried using a stereo 1/8" plug from my PC to 2 1/4" Mono plugs, and so far it has worked just fine. No problems with hum or other interference. I wish I could find a smaller amp with more gain and 1/8" stereo in and out at a comparable price. The Behringer has lots of bells and whistles, input level controls, LED sound level meters, and two separate inputs. Each output can be selected for input channel 1 or 2. The level meters are handy, but could be annoying in certain circumstances. Overall, I'm satisfied with this product.

Hi Folks... My wife and I are the executive producers of a radio show and online TV show. I have constantly had an issue routing audio to headphones through a device that worked perfectly and offered options for an additional 2 outputs we could control. There are several pricy devices available - and buying two to handle our needs... too much equipment on the desk. Then I found​ this little gem.A few reviews sounded critical, but I figured for the price, why not try it. I'm glad we did! This is a champ! It is quiet running - no hiss when no signal is present. And with individual level controls for each headphone (or in our case 2 headphones and 2 audio monitors) you couldn't ask for anything better. why buy a more expensive device? This is well made, a little light but so what... and it performs! That's the best part!If you are looking for a device like this and wondering (like we did) I know you will be very happy with this. We are, and would buy another if the need arises.

They were hard to find (I bought my first mic preamp in Belgium!), but these simple equips are truly good, high quality, and this MiniAmp is very flexible and complete with whole LED control. Two stereo inputs lead to Four Stereo Outputs.

It's loud and clear and has great metering, multiple inputs and solid plastic build. For under $40 this thing is a steal! I share it with my studio partner who uses the A channels and I use the B channels. You can switch your headphone outputs to either get signal from the A or B inputs. Since we share a common vocal booth with 2 different control room set ups we are able to both use this device because of the two inputs. Very handy indeed!! In a pinch you can use the additional 4 headphone outputs on the back of the unit. It has TRS inputs so that you can run a long balanced signal to it. That's a definite pro feature and important if you ask me. I am truly a gear snob when it comes to buying pro audio equipment but I am not ashamed to have this unit in my studio. It works! It works well!!
