AKG B48 L Instructions d'installation

Please read the manual before using the equipment!

The B48 L is a battery powered one channel phantom power supply

for P48 condenser microphones. The 48V power supply is for those

applications when a condenser microphone is used where no

phantom power from a mixer is available. The additional mini-XLR

audio output and the included mini-XLR to mini-XLR connection

cable support a direct connection to all AKG body-pack

transmitters. The phantom power of the audio input supplies

microphones with 48V and meet the P48 standard. B48 L is

designed to meet the demand of lowest noise level even in

operation with high-end condenser microphones for professional

applications in theater or touring applications.

Insert two batteries into the battery compartment, aligning the batteries with the

polarity symbols inside the battery compartment. The B48 L provides a polarity

protection. If you insert the batteries the wrong way, the B48 L will not be

powered. Press the ON/OFF button
