Product Details

Harrison Labs 12 dB RCA Line Level Audio Attenuator Pair
Attenuators reduce the drive signal to an amplifier so that the input level or gain control can be adjusted in a more useful range. For example, if the line driver has an 8 volt output and the amplifier has a 100mV (0.1V) to 2 volt range of input level, the gain pots would have to be all the way down. A 12 dB attenuator would allow you to adjust the amp's gain control to about 1/2 rotation. Many home A/V receivers and basic amplifiers do not have input level controls and attenuators are also perfect for these applications. Sold in pairs. 24 kt gold over brass construction. One-year manfacturer warranty. Made in the U.S.A.

Harrison Labs 12 dB RCA Line Level Audio Attenuator Pair is rated 4.4615 out of 5 by 26.
Rated 4 out of 5 by from Did the job--Excellent!I purchased these to match input voltage from a DCX2496 to my prepro, and it did the job perfectly. It completely eliminated the clipping problem I was having by overdriving the input signal. I highly recommend these. It would be nice if they were shorter, but they work.

Rated 5 out of 5 by from Excellent productI bought this article, and it solved a problem I had with my home theater setup. This is a great produst!

Rated 5 out of 5 by from Gets the Job Done!I purchased these to better match my tube preamplifier and a high gain solid state amplifier. Worked out great! Significantly reduced the tube hiss/rush heard through the speakers. I can now enjoy the quiet passages in the music with out any distracting noise. I also have more control when making volume level adjustment using the preamp volume knob. I can now really appreciate my new tube preamp. These are kind of pricey but its worth the cash considering my only other alternative would have been to buy a quad of lower gain tubes. Highly recommended.

Rated 4 out of 5 by from Great item, solved my problemAfter years of strugling with a harsh sound and an uncontrolable volume knob, these attenuators solved my problem.In the last five years I tried different kinds of interlinks between my CDplayer en amplifier, different kinds of speakerwire,etc. etc.I could've saved a lot of time, money and energy by buying these attenuators.I'm very happy, but not sure yet if they alter the sound. The higher frequencies sound a bit tempered now, what makes it more enjoyable to listen too.4 stars, because I'm not sure yet if they alter the sound.

Rated 4 out of 5 by from Rugged, look great, and perform as expected!So why four stars? They're a mile long! But I guess that's as small as they can be yet work as transparently as they certainly do. And delivery faster than anticipated.They attenuate so well that it was hard to set an agreeable volume on movies on VHS or DVD. So I ordered the 6dBs which came today and threw them on the back of my receiver Video input. 6dB, contrary to what most will say here, works fine for my situation. Still great sound, and easier to set volume.The 12dBs are now in my CD chain, which means even the LOUDEST CD on the charts ain't clipping my receiver. Music CDs tend to be less dynamic(soft to loud) and thus higher avg. volume(RMS) than DVD movies, so actually putting the stronger pads on them is a win-win: Little or no volume adjustment when the evening turns from music on the Sony changer to a movie DVD. :)

Rated 5 out of 5 by from Harrison Attenuators - work very gooD !!The Wyred 4 sound amps have very high gain ,and my tube pre is sensitive single ended ,this setup amplified the Noise on the modified Dared PreampVolume near the 7 pm position ,and getting a bit of hum threw the speakers.I bought these 12db per octave attenuators now the volume is up near it'sOptimum level on the rotation ,less noise By the attenuation installedOn the amplifier inputs.,Higjly recommended !!

Harrison Labs 12 dB RCA Line Level Audio Attenuator Pair

Mixer has RCA record outs max at +10 dbu and our TasCam DR-5 recorder has max in at -4dbv. With the recorder at its lowest setting I get clipping on music a lot. If I turn the mixer down we lose room quality. What size attenuator should I use a 12 or 20?

Asked by: Cleo
Instead of using a set attenuator you may want to use a balanced to unbalanced converter. Part # 233-168. This will allow you to vary the input as needed.

I was interested in the Harrison Labs 12dB Line Level Attenuator pair. I wanted to connect our Yamaha PSR-433 keyboard's headphone out to the stereo RCA of the stereo system. The headphone out comes out too strong. Will attenuator work?

Asked by: bsl100
You may have to use an adapter to convert the typical 1/4" to RCA type but it will reduce the level by about 12db. The other option would be to use a headphone amplifier to control the output.

Basically, do these reduce the outputs volume level so that it takes less power, or are they so you can turn the volume up louder? Can someone please explain to me the purpose of these?

Asked by: RobbyT
These reduce signal levels into an amplifier. If the signal is too high and causes the input to clip, these will reduce that level and lessen the clipping problem.

This is recommended by Tweek Geek for the M2Tech Hiface USB to SPDIF converter

Where would I install these attenuators? My current set-up is PC's USB to HiFace converter to DAC to Receiver.
Asked by: Kwhardin
Tweek Geek is recommending that one of these goes between the HiFace converter and the DAC. These are directional so they should be used at the DAC input, assuming that you aren't using any gender changers on the RCA cable. Using it in the opposite direction will give you a lower attenuation level. The actual attenuation level that you achieve will depend on the input impedance of your DAC. Some experimentation may be necessary including no attenuators or both attenuators.
