    Rolls RA53B reviews

    RA53B - 5-Channel Headphone Amplifier is rated 5.0 out of 5 by 7.
    Rated 5 out of 5 by from Versatile little box! This is probably the best solution for a portable, pro headphone amplifier at the $ price point. What sold me about this unit was its wide range of input configurations and the fact that it does have both size headphone output jacks, which is perfect for working with clients who have their own headphones but not the adapter. These amps have plenty of clean, quiet gain. More than you will need and enough to blow up cans. It doesn't have an input trim so you ought to have some gain control at your source output. Your best bet is to run signal into this thing at unity gain. It is built very well and has a solid, steel chassis. Built in the USA, too.All in all a great piece of equipment that will save the day for only $

    Rated 5 out of 5 by from Perfect! So nice sounding and extremely well made. Nothing extra and having the little outputs for consumer headphones is a plus when mixing. Love this thing!

    Rated 5 out of 5 by from Great device. I use this for my internet radio show, so that my guests all have a headphone. This device is made well and does a wonderful job.

    Rated 5 out of 5 by from Versatile, easy to use, and affordable! It's been a few years since being in need of a new headphone amp. I've owned an older version of a Rolls headphone amp and I really liked it for my professional recording studio... so much so that I bought 4 of them for all my sound rooms. It's been several years since I left the recording industry but over the last year I've been podcasting with some friends of mine and I'm getting my new (tiny) home studio up while upgrading equipment when I have the extra cash to do so. I ran across this beauty that has everything I need, plus more! This is a major step up from the ones I owned in the early 90's. The biggest plus and difference is being able to use other 1/4 or 1/8 jack on the front. It saves me from making sure I have the correct adapter if someone brings his or her own headphones or earbuds. It also has the LINK/JOIN capability of which I have used on previous models and comes in super handy if daisy chaining more than one box together. Works in either mono or stereo. You can't pan but that's not really the purpose for which this was designed. If you need more individual control as opposed to a stereo or mono headphone signal, I'd suggest buying a small 4 channel mixer. It's quiet and discrete, I don't hear any extra added component hum or buzz even when linking two or more boxes. It's not having to drive a bunch of wattage so the unit itself doesn't radiate any measurable heat to the touch. My signal chain: I have my Soundcraft Signature 12MTK headphone out (stereo) TRS 1/4 to 1/4 split L/R into the headphone amp. I drive the Soundcraft headphone out gain about three-quarters to full. The headphone amp takes care of the rest of the gain. No hesitation in purchasing another one of these. No hesitation in recommending this headphone amp to others. I've owned other and less expensive headphone amps but none of them have all the functionality and solid workhorse longevity as the Roll RA53B.

    Rated 5 out of 5 by from stupid good headphone amp plugnplay. Gobes of clean LOUD sound. I bought this rolls headphone amp to use on the tv in the bedroom, so my wife and I could watch movies in the evening/night and wake the kids. I find myself using it all the time day or night. I can listen as loud as I like and the wife doesn't nag the the volume is too loud.

    Rated 5 out of 5 by from This is a great buy and worth every penn This is a great little headphone amp and worth every penny. I use it for remote broadcasts and it is a perfect fit for my application. Five headphones sounds like a lot but we fill it up very quickly. I highly recommend Rolls products. We use Rolls in all of our applications.

    Rated 5 out of 5 by from Love it! I use this instead of my stereo for my headphones. You can adjust the volume and it works great when playing my drums. Needs a longer power cord. I would highly recommend this!!!
