For anyone serious about maintaining top-tier audio quality across various setups, the Shure A85F is an investment that will pay off in reliability, clarity, and seamless integration.

Device works as expected...no noise or hum on 50 yr old vintage equipment. Thank you SURE !

Works great. I'm using it to turn a lo z mic into a hi z mic and it is clean as can be

Works as it should. I needed an adapter (transformer) to connect a microphone to my guitar amplifier in order to use the amp a PA system. This did the trick.

Thing does exactly what it says! Passive gain boost, and now I can run a 57 or 58 through guitar pedals without having to use a preamp on my board. Very clean, well made, can;t recommend it enough!

Epic purchase ! Thank you Shure

Worked well, durable and quiet, would buy again. I had several, one the plug separated from the stem inside an amp input and I can't get it back out, which is a hassle.

it worked with my pick-up, it provides good level to connect your pick-up to an amplifier or sound recorder

A bit too expensive -but show good quality. Have used my first one for 20 years. The transformer circuitry is stable and reliable -but produces a significant decrease in sound levels.

Très bien. Produit de bonne qualité.

Excellent product. Gives impedance matching and 24db boost to the signal so I can now run a microphone pickup through my guitar pedals. The only thing I would prefer is if the jack end had a lead attached as it’s rather long for plugging in when an xlr cable is attached to the microphone end. I purchased an extension lead myself to solve this problem.

Working well as expected

Appears to be well constructed. It works, unfortunately, it adds some slight humming noise.
