Shure A15AS Switchable Attenuator (15, 20, 25 dB), Passes Phantom Power

This lives up to the Shure brand. Construction and feel are solid. It works perfectly and no sign of any signal degradation. Mixer board XLR out is line level, and typical XLR feeds to house systems are mic level. This attenuator does the job. I've pretty much set it to -25 and plan to leave it there. Pro line level is +4. consumer line level is -10. My equipment is pro so I need the full -25db. Not that I can imagine consumer level with XLR but if you come across it you may use one of the other 2 settings.

These were a GAME CHANGER for my simple 2.1 home theater setup. Before I got the Shure A15AS, I had to turn my sub volume basically to max in order to match the main speakers. Now that this level mismatch has been fixed, I can turn the sub volume back down to around 0dB, and not only is the system more balanced, but the bass hits harder since the sub is now much louder in comparison to the mains. This also gives me the flexibility to turn up the sub even more for music or films that lack low end, whereas before there was no way to turn it up further. These are also built like a tank and will probably last a lifetime. Highly recommended!

Awesom and works as advertised Shure is at top of there game

Works great for padding the signal of a home-made subkick style woofer microphone for drums.

Sometimes there is not enough volume and you need a preamp, but sometimes the problem is just the opposite and there is too much volume. For this kind of problem, this little thing is a great solution. It seems to work great with the Zoom H4n, which has really "hot" premaps. Line in was blaring if the volume wasn't way down, so this seems to bring the volume down to a reasonable level. The mic seems to clip a little too, so if I keep the Zoom H4n, I might need to get another one of these. What is nice about this little gadget is that it is switchable. I don't always need the highest setting so it's nice to be able to choose a setting that works for my set up. So far I am happy with this product.

Only had to use it once so far but it behaved exactly as expected. It gives me piece of mind to know it's sitting there in my kit waiting for the next time someone hands me a ridiculously hot signal.

Great for API 512c preamp that doesn’t have an output control. I stick mine on the output to converter and now can use DI boxes better. On my API512C I noticed just because it hits red doesn’t mean clipping! This is the go to for API 512c preamps! I just set it at the lowest option and was good enough to turn up and hit no louder than -12 to -6 or so. I wasn’t able to turn my API up more than 9 o’clock before this. Now I can go noon or more for the mojo of that preamp.

Two of the several DIs I use for bass guitar put out signals that are way too hot for the boards I feed. This attenuator fixes that. The ability to adjust attenuation is a great feature. And yes, it really does pass phantom power. Both DIs I tested it with run on phantom power, and both ran fine with this unit in the signal path. Great quality, too. Feels well-made, including the slide switch. Tip of the day: Don't cheap out on things like this. Spend the money and buy the good stuff. Shure knows what they're doing.

マイクレベルの入力しか受け付けない会場の音響装置にラインレベルの出力機器を接続する際に使用しています。 本体が長いので、XLRケーブルの中間に挟んで使いました。

Lo compre por que uno de mis micros sonaba demasiado fuerte y no traia pad pero al poner el adaptador si suena mas despacio pero distorsionado y conste que ya lo probe con muchos micros.

very useful device if your running from your own mixer and stage speaker set up and you want to run a line into the house mixer and speakers for additional set up and volume this is ideal it has 3 different db settings via a mini toddle switch this prevents your mixer line out from overloading the house mixer input preventing overload and distortion its not cheap but worth having in your cable box

I had trouble connecting my XLR output from my Ampeg Micro VR to my UR22 interface because the levels were too hot. I had to set the level control on my interface at about 0.5 to control peaking. After trying several cheaper options I settled on this Shure A15AS and it does the job perfectly! I had to set the attenuator to -25 to get the levels I needed.
