Rolls PB 224, Mic Power II B, Phantompower-Adapter, Phantompower for 2 Condenser Microphone, 48-V-Phantompower, XLR In- and Outputs, Powered by external power supply included or from battery power 2 x 9v
I bought the Rolls PPB 224 to supply 48v phantom power to my pics in the field. I am working on a recording project collecting nature field recordings from along the length of a river here in the UK. I need to power a pair of Rode NT1a mics as well as a pair of spaced omnis. I'm also using hydrophones. The point of this review is to tell you that even when using the Rodes, with their very low self noise, the Rolls adds nothing I can detect to the signal.. it is dead quiet.
The down sides? None really. It is a little bulky if you're using a handheld recorder. It takes 2 P style 9v batteries rather than 1 but I bought some very long lasting rechargeable so should mean not changing very often.
I would recommend this product over competing products costing less. I have used one of those and it added audible hum to the signal path, which for my. Needs makes it not suitable. The Rolls is solid, well made, and above all audibly transparent.
Thomann provided me with excellent service and fast shipping to the UK, so thumbs up there too.
This is most likely the only portable battery phantom power supply that has good sound quality. It probably doesn't give you the full 48v (like most battery powered units) but it comes close and works with most mic's, as long as you use small condensers. The build quality is good, but the unit is a touch to big to my taste and the on/off switch a bit difficult to reach. But in the end it's the sound that counts. PS: I never used it with the power adaptor, only with battery's.
