Finally presentations without disturbing noises! It happens to all of us:
At home the sound was clear and clean, now humming in the lecture room and chirping it over the speakers. There is no time left for troubleshooting. The Palmer vils, a Line Isolator Box, provides a reliable solution that separates the ground potentials of laptop or media devices and public address system.
The Palmer vils has two unbalanced phono inputs. To connect to the laptop's headphone output, you can use a commercially available Y-cable with a 3.5 mm jack plug. The vils sums up both stereo channels to mono, so you only need a free microphone input for connecting to the sound system.
The Palmer vils is extremely simple in handling Because of its passive mode of operation, it does not require a power supply; for an optimum adjustment of level and impedance, a resistance network and a transformer which simultaneously balances the signal are provided. Thus there are no disturbances even for longer cables.
With the Palmer vils you can finally rely on your presentations in the lecture room to sound just as clear and clean as at home.
