Neumann USA is introducing the N248 Power Supply at the 117th AES Convention in San Francisco. The N248 supplies one stereo microphone, or two mono condenser microphones with 48V phantom power (P48). All connectors are of XLR 3 type. The audio signal outputs are DC-free. The five directional patterns of the TLM127 and TLM170R can be remote controlled with rotary switches.
The remote control operates by varying the nominal phantom voltage of 48V over a range of 3V (patented). As in standard operation, cable lengths up to 300 meters are permissible. Set to P48, all conventional microphones can be used as well.
Even mixed operation is possible, with one-channel remote controlling a TLM127/TLM170R, while the second output supplies a conventional microphone.
