[0.1 lb] I am using the A15LA-Line Adapters with a Zoom h4n. In my situation I am using strictly XLR connectors which means mic level into the Zoom (which also means distortion when not balanced properly) The A15LA-Line Adapters allow me to use XLR inputs into the Zoom with clean/no distortion from my signal input. The A15LA's fit in my field bag easily and take up very little space, look and are professional quality, and best of all get the job done right. I have NO criticism what so ever of this product.

[EQ Filter] Filter really makes a bold difference in astro imaging. Noting that the lens sun hood doesn't fit over the knurled edge of the filter. I can live with it since a sun hood is rarely needed at night... if I were to use this filter for artistic reasons during the day I might have another thought

[EQ Filter] Help me out with this. You do event work where you occasionally have to take a feed from a mixer with line level outs. Do you spend at least $400 for your own mixer to knock the feed down to mic level? Or do you buy this great little behind-saver? That's what I thought. Case closed.

[0.1 lb] Finally got to use this for the first time last weekend on Jupiter. Provided nice, sharp images to combine with my Baader RGB filters

[EQ Filter] I live in heavily light polluted skies, yet I can go out in the backyard and look up at the billowing clouds of the milky way. I can actually see meteorite showers when they are happening. This is all possible by using this filter in conjunction with a Gen3 night vision device. This filter blocks out all light below 685nm which is basically all the man made light pollution leaving mostly celestial light for your enjoyment. This does cut out hydrogen alpha light, so you will not be seeing nebulae with this, but a separate band pass filter is used for that purpose.

[0.1 lb] For location interview sound in semi-uncontrolled environments, this cuts the lows without completely compromising voice quality. You don't always have room for a mixer and an extra person so when you are sending a mic directly into a camera, this really streamlines your sound quickly.

[EQ Filter] A friend of mine recommended this to me and I'm greatful. I use this high pass filter to cut low frequencies going to my in-ear monitor and also to cut low hz on side wash powered monitors. I get plenty of bass from my main subs so the Shure A15HP is a good fit for my situation.

[0.1 lb] I film live events using Canon XL2 cameras. The cameras are a great tool, but they do not accept line level audio input. It must be mic level. On one important shoot, I double checked with the audio technician if he would be able to provide mic level input. He told me that he could, but in fact he could not. I showed up to the shoot without audio tie in. I was forced to use my own mic system. At least I was prepared enough to do that. Never again. These little in line adapters do a fine job reducing line level to mic level without having to carry lots of other equipment.

[EQ Filter] I needed to step line level out of a mixer into a mic input because of consumer gear in the setup. After researching db difference between line and mic standards and looking at switchable and static attenuators I ended up picking this one for the name brand and 50db. The step down was spot on, I had all my levels at unity and appropriate gain.

[0.1 lb] It's a plug and play device we use to record in-air cockpit conversation for videos. All I know is that it works with everything from tiny voice recorders to more expensive cameras. Without it you'll get blasting, unintelligible cockpit conversations. It works.
