B48 L battery power supply offers more than 20 hours of performance 10/04/13
AKG has launched the successor to its B18 condenser microphone battery power supply with the introduction of the B48 L. They say that, with its very low noise level, a frequency response of 20Hz – 24Hz and an inverse polarity protection feature against incorrect battery insertion, the B48 L Battery Power Supply provides users with more than 20 hours of use on only two AA batteries.
When phantom power for a condenser is unavailable from a mixer, the B48 L phantom power supplies microphones with 48V and meets the P48 phantom power standard. Additionally, B48 L's mini-XLR audio output and included mini-XLR to mini-XLR connection cable supports a direct connection of condenser microphones to all AKG bodypack transmitters. A low battery LED light illuminates if phantom power drops below 40V.
Wolfgang Fritz, Product Marketing Manager – Tour Sound, AKG, told us, "We've designed B48 L to replace our original B18, which required two expensive 9V batteries and didn't support P48 standards. Many of our more advanced microphones, including the C414 do not allow for voltage lower than the P48 standard. Now, we can be sure to accommodate all users so their AKG microphones have proper power and provide the quality and reliability we strive to offer professionals around the world."
