Rolls HR-155 Reviews

Used as confidence a monitor.

A 1 ru small form factor half rack space audio monitor , with unbalanced and balanced inputs. I use the HR155 as a confidence monitor to check for, audio , present , Hum , Buzz , cracklings , etc. The unit is mono output thru two speakers ( not stereo ) refer to circuit diagram. Don,t expect Hi Fi sound , in such a small unit . I purchased 2 units to Monitor my X-AIR , XR-16 digital audio mixer , left and right outputs. I placed these units in my own 1ru I was happy to void my warranty by opening up the unit and placing some acrylic speaker damping material inside , behind the two speakers to make the units sound a little better . The transformer plug pack is 15 volts output with a negative centre pin and a USA pin plug. ( I'am from AUSTRALIA ) But I also have found it will happily run off 12 volts output ( the more common ) keeping in mind the negative centre pin and I use a 1 amp switchmode plugpack on each unit with of course an Aussie pin plug. For performance monitoring I use Behringer MS40 Studio Monitors. Hope you find this review helpfull .

This product is fair but I would not purchase this again and would spend a few more $$$ to get better volume and quality sound.
