I am using this for the boom operator in video sound production. One gotcha' is the line/mic setting. If your aren't careful, it can easily get set to line and the headphone amp doesn't give nearly enough volume. Also, I would have liked to have more technical information about the limiter function, like where is the maximum and what is the shape of the amplitude curve?

See any errors on this page?

question

Hi just wondering why the rolls pm355 is priced the same as the pm55 as the 355 is 3 channel does the 55p have any benefits over the 355
Asked by: Dan B.
If you're talking about the PM351, the benefit of the PM55P is that it can be powered by a 9v battery.

question

Will this item work with a condenser boom mic (provide phantom power)?
Asked by: Davin P.
I don't think it provides phantom power but it does allow it to pass through? So send phantom power from the recorder (or TX if going wireless) and you should be good.

question

Is the headphone amplifier RF protected? Time ago I bought a ROLLS PM-55 and I had problems with cellular phones interferences
Asked by: Erick
Yes, a cell phone in close proximity can cause interference. I would recommend using airplane mode.
