Hosa ATT-448 In-line XLR Input Attenuator

Bought two of these so the line out from my pro mixer can be fed into the XLR mic-in's of my Zoom H4n recorder. The Shure A15LA line-to-mic adapter cuts the signal by 50dB and only 50dB. That's too much attenuation. These Hosa's give me selectable 20dB, 30dB or 40dB of attenuation. Just right.I send 0dB tone from the mixer's line-out XLR through the Hosa attenuator set at -40dB, and adjust the H4n's input level until the VU reads -20dB on the H4n. This allows me to run the H4n's input at about 37 of its 100 units.If I set the Hosa to the -30dB switch position, the H4n's input level is at 5 units for the VU meter to read -20dB.At these settings, I get 20dB of headroom on the H4n to avoid distortion. I can safely run my mixer to bounce at 0dB and occasionally peak at +15dB or +20dB without fear of driving the H4n into distortion.This also does not require me to run the H4n's input up so high that I start getting noise. Using the Shure A15LA, I had to run the H4n at about 75 units...a little more than I wanted to.And considering I got two of these Hosa's delivered for the same price as one Shure attenuator, I consider this an excellent, high performance deal.The unit is 3/4" diameter and 3-1/2" long when installed, 4" overall (the female XLR connector extends past the main barrel 1/2"). The dB selector slide switch is easily moved. May want to tape or hot glue it in place so it doesn't move accidentally. (Hot melt glue works great for semi-permanent yet removable "locks" as it leaves no residue like tape. Also allows you to see the setting easily.)

Needed to take AUX or Phones out signal from a sound mixer that would feed my Pentax K-3ii mic input for videoing sermons in my church. While mic level is about 0.001v, AUX or Phones out are line level and is 0.5v to 1.0v... a HUGE difference that can damage a DSLR if you input a line level into the mic input without attenuating it!The solution?The Hose ATT448!Took a Hosa XVM-105M Right-Angle 3.5 mm TRS to XLR3M Microphone Cable, 5 feet (https://smile.amazon.com/Hosa-XVM-105M-Right-Angle-XLR3M-Microphone/dp/B0010CTL66/ref=sr_1_1?ie=UTF8&qid=1472781885&sr=8-1&keywords=Hosa+XVM-105M+Right-Angle+3.5+mm+TRS+to+XLR3M+Microphone+Cable%2C+5+feet) on one end of this Attenuator that feed the camera mic input,then...Took a Hosa STX-105F XLR3F to 1/4 inch TRS Balanced Interconnect Cable, 5 feet, from the other end of this attenuator and connected to my mixer AUX output. (https://smile.amazon.com/Hosa-STX-105F-XLR3F-Balanced-Interconnect/dp/B000068NYT/ref=pd_sim_267_3?ie=UTF8&psc=1&refRID=K6Q0J561H3FFC329475C) Set the attenuator to -40, the camera to Auto mic level and my videos have crisp and clear audio!Using these types of cables eliminate adapters (e.g. using a standard XLR mic cable with XLR to TRS adapters) which in turn reduces the number of connections points that can go bad!Anyway, if you have a DSLR with a Mic input for your video this is the thing to get that professional level of sound which is going through a sound board (aka mixer). Whether you are recording sermons, speeches, confereneces, etc. this works like a charm!

Use these in line out of the mixer to send L/R through the house snake down two channels.They work as they should.

I run our video broadcast/youtube stream at church every week. The audio feed from our main sound board up to the video booth has always been a very hot signal and there really wasn’t a way to dial it down the way that particular sound mixer works.I’ve struggled with this for quite a while, as I would run into the audio level getting clipped and peaking at the video system. Finally found this and gave it a try.AMAZING!!! All I needed was a 20dB cut. My levels are perfect now, no peaking and clipping! Zero audio noise from this adapter either. Why oh why didn’t I buy this years ago!

I also own the Audio-Technica AT8202, which is a little more than double the price. Gets the job done just like the AT8202. Only difference this allows for more attenuation up to -40db. The sound quality is the same, very transparent, I can't hear a difference between the two. Where this lacks is the build quality, it defintely feels really cheap. I wouldn't be rough with this, it feels like it won't last long, one wrong move and it'll break. I'd say this is more for home, than professional use.

I'm using this at my church. We hold service in a place that it's not our own and our host recently upgraded their sound system. In doing so, they gave us mic inputs with which to connect our sound board. Our board, of course, has line level outputs. This caused massive distortion as our line outputs massively overloaded the mic inputs.I experimented with the 3 attenuation settings available on this adapter and found the 40db attenuation to provide the best results.I was a little hesitant to buy this attenuator as my use is a bit "off-label" from the item's description, but I thought it would work and, indeed, it does work a treat!It was an excellent purchase.

The very first time I used this it broke.I connected the female side to another XLR. When I was ready to disconnect them, I pushed the button on the male part that unlocks them so you can pull them apart. When I started pulling them apart, the female part of the attenuator started coming out. I looked at the part to see why it wasn't staying in, and it was because the screw that is supposed to hold it in (this is the screw that you see on the left side of the attenuator on the picture on display) was screwed into some broken plastic on the female part.I tested this and it still works, but I don't think it will last very long with the female side the way it is, and it is really crappy to buy something and have it break the very first time you use it.
