I had no way of reducing the strength of the signal going into VinylStudio while recording LPs; it clipped all the time. These reduced the strength just enough.

These attenuators perform as expected, and I have measured an attenuation of exactly 6dB, which is actually not a big trick to achieve with precision. Yes, I could easily build these in my shop for about a dollar each in components, but the packaging and convenience merit the price, in my opinion.Some users have complained that they are "unidirectional", yet this is the case for any passive voltage divider.If you know your use case, these will fit perfectly, as they did for me.

I'm going from a Thorens TD145 with an AT VM540ML moving magnet cart into a Parasound Z-Phono phono pre to a Panasonic XR-55 receiver. Even after engaging a 10db pad on the receiver, the cart / pre combination is just too hot and was making for a ton of clipping when recording to the PC. (My PC sits in the tape loop of the receiver). I already had the line-in slider all the way down in Windows. There is no registry hack. And yes, I checked the ZPhono twice.. it's set to MM, and there is no gain (or cut) switch on Z-Phono.Solution? These 6 db attenuators. But do pay attention, people! They are uni-directional. The way they're made, they ended up on the receiver side of things. I wonder if those who complain here about "muffled" sound simply had these backwards. [source] ---->[attenuator]------>[receiver / pre]. This is the *only* way this will work correctly! Essentially, the attenuator goes on the RCAs going to your receiver / preamp. These things are two inches long, so keep that in mind. I have plenty of room behind the receiver so for me that was no problem.Sound? Still wonderful, but 6db quieter, which is enough for me to finally dump vinyl into my PC with no clipping. I"m serious -- all the "air," "sheen" and all that audiophile jazz is still there.. it's just all 6 db quieter. I played my piano teacher his 1960's Living Stereo LP of Peter Nero doing Gershwin's Piano Concerto, and we were both just transfixed at what was coming out of my Klipsch Fortes (the OG ones from 1987.) Brilliantly explosive, in two words. Superlative, in one word.Thank you, Harrison Lab, for making these... now I don't have to McGyver a solution with a variable pad I have somwhere around here.

Using this between my Oppo UDP-205 preamp and Parasound A52+ amp. Previously I used this with a lower quality class D amp. This does a good job dropping the signal level so I can avoid the problematic lower range of the Oppo digital volume control. 6dB is about perfect for my setup. However, it does affect sound quality. For me, the midrange and overall punch or dynamic range became muffled. Didn't notice this so much on the class D amp. Good for entry level systems, but not so much for mid/high end gear.

These attenuators work fine, though I knocked off a star as they're unidirectional but not labeled or marked as such. For reference, the female side is the input, and the male side is the -6dB out. Had I known this I would have ordered RCA elbow adapters to attach these to the back of my power amp. Now I have to wait two whole days for the adapters to arrive--first world problems, huh?I have attached o-scope screen grabs to show the performance of these attenuators. One shows what happens if they're inserted backwards (no attenuation) and others show the bandwidth throughout the audio range (10Hz to 20kHz). There's a slight delay in the attenuator circuit, which is shown by the marginal phase misalignment in the 40kHz plot. Naturally, the plots show a cut of half the input voltage, which correlates to a -6dB output.

6dB is indeed enough - for my application - padding video and CD inputs on the back of my 80W/ch JVC receiver.I will save my 12dB pad for other inputs.I highly recommend these to the average consumer who does not have a separate pre-amp/amp combination or does not know how to adjust the insides of their gear.Being able to hear ALL the sound, soft to loud, deep bass to tingly top, with smoother volume adjustment, is worth it.Thanks Amazon and Harrison Labs!

Used these to pad a RCA line to my amplifier.It ended up cutting about 7-8 dbs of level with no real appreciable difference in tonal qualities.
