[3 x 1 x 1"] We use these on all our Audio installs to provide a user friendly option for all customers input needs!

[3 x 1 x 1"] The cable worth every penny! It's not Cheap but superb. Like it a lot

[3 x 1 x 1"] used for audio power point presentations and it works great for controlling output volume

[-30 dB] Very useful in knocking down the audio from mixer to camera

[-30 dB] Excellent right out of the box. Very sturdy and delivers what it promises. I am a small local magicial entertainer and needed a device that I could hook up my Sony CD/IPOD player to my Fender Passport amplifier and speakers. Since I travel to many different types of locations, this seemed the ideal product to use...after trying other avenues. You wont be dissappointed in its performance.

[Attenuator/Pad] I use this cable to connect our show audio computer to the sound board. Great sound quality and takes the abuse of plugging and un-plugging constantly moving from the tech table to the booth.

[0.1 lb] I needed to connect a sub-mixer into the house system at a church for a special program. When I plugged the mixer into the sytem I got a huge amount of static and HF noise. When I turned on the mixer I got a local radio station broadcasting a basketball game! I inserted the AV1 and everything went away but some 60 cycle hum. Flipped the handy ground lift switch and silence. Zero noise! The difference was amazing, beyond my expectations. I highly recommend this product!

[-30 dB] I purchased this nifty piece of audio equipment after I saw it used by AV pros. I do a lot of Powerpoint presentations that include video clips. Sometimes the audio in the clips is too low to hear, which makes them worthless. This unit boosts the sound level up to normal levels, saving the day. What a wonderful life saver. Worth every penny.

[3 x 1 x 1"] Works perfectly for patching an i-pod and/or laptop into pro sound systems in theaters with great results. Plus the added bonus of stereo output! Must have for any sound F/X playback or music streaming in theater settings. Build is tough and durable... absolutely no 'chince'-factor!

[Attenuator/Pad] I wrote a review earlier for this product, that it worked very well in removing noise from a setup plugging a mixer into a noisy church building system. I recently found another, unexpected use for this item. I also play guitar in a band. Those out there who may play an electric guitar with single coil pickups know that these instruments are subject to noise. My practice space has got some pretty noisy electrical wiring (mainly from multiple light dimmers), and I have always had problems with noise when playing my single-coil-equiped Stratocaster. I have done several things to reduce the noise, with variable amounts of success. The other day while playing, and experiencing a noisy condition, I had the idea of using this interface between the guitar and amp. Bingo! Quiet! Hard to believe, and it doesn't color the tone, either (not that I could notice, anyway). If guitar players get wind of this, sales of this product should skyrocket! (funny they don't advertise this -- Pro-Co makes guitar effects, notably the Rat overdrive pedal) At any rate, I will be including this from now on as part of my regular guitar setup.
