Product Details

Rolls MB15b ProMatch Balanced/Unbalanced Converter 3.5mm/RCA/XLR

One side of the MB15b (labeled 1) has two XLR inputs and stereo RCA outputs. The other side (labeled 2) has stereo RCA inputs and two XLR outputs. Each side has a stereo level control, and an LED indicates that power is applied to the unit. An additional benefit of the MB15b is that it will act as a balanced XLR line level control. By adding a stereo pair jumper between the four RCA jacks (connecting ins to outs), the two level controls may be inserted into any balanced XLR line. Made in the USA.

For more than two decades, those in the know have turned to Rolls for the highest quality, reliability, and value. Rolls is an innovative company specializing in domestically manufactured signal interface accessories, mixers, amplifiers, and processors for the audio professional.

Rated 5 out of 5 by from Pro Audio in Home SystemI have 3 Crown XLS 1000 pushing 6 18" FI Car Audio IB subs. The output was dismal even with gains turned all the way up on amps and on my Denon receiver. I started thinking about the pre-out voltage from my receiver and figured this was the problem.I purchased the Rolls MB15b, hooked it up, turned the gain to half way and BAM! There was the bass I was looking for.I now have amp gains at 90% and my Denon bass gains on -2db only using 3 of the 6 18's.If you are using pro audio amps in your home system, this is a MUST HAVE item. Don't think twice, just order it!

Rated 5 out of 5 by from Great Audio ConverterWe use this gadget in our Function Venue to convert IPOD or Laptop sound from RCA to XLR so we can run the sound through our pro in house sound system. Easy to use and does the job perfectly! Love the product and it is so hard to find a user friendly alternative so this is my second one.

Rated 5 out of 5 by from Made the world of difference !!!i have a crown xls1000 and use it for HT subs , but my receiver puts out the standard -10db output and got a fraction of the wattage. the sound just wasn't there, until i hooked this up. It brought it to life, the difference is night and day. now the sound is incredibly powerful, and very tight, anybody that needs to hook consumer grade stuff up to pro audio stuff i highly recommend this. now i have +4db output and the full potential of the amp and way better sound quality.

Rolls MB15b ProMatch Balanced/Unbalanced Converter 3.5mm/RCA/XLR

Can this be used to match Reciever LIne Outputs to Pro Amp?

I was hoping to use a Crown Amp (XLS 2500) to power a couple subs. Crown rates full power at 1.4v input whereas the maximum output from Yamaha RX820A is 1.0v. Can this unit be used to get maximum output from the Crown amps?
Asked by: War Eagle 81
This item is very good quality, but you may need a "real" preamp to get to "Professional 1.4 Volts RMS". I will include suggestions below. The slam dunk, is a low cost mixer that will take whatever your Yamaha delivers--even a -20db signal and convert it to as high as +20 db [if needed]. I have a few of these Behringer mixers--Real Pro/Low Cost/Quiet. And they look cool!! They are available with 1/4" phone outs or 1/4" + XLR outputs. There is also stereo RCA inputs-1/4" phone and XLR inputs.
