Palmer vils Channel Merge Line Isolation Box
At home the sound was crisp and clean but during thepresentation it hums and buzzes and there is no time to figure out the cause.
Here is where the Palmer vils comes in handy as It’safelyisolates the ground potentials of the laptop, media devices and PA systems fromeach other. (Calm returns and the audience and you can concentrate fully onyour presentation again.)
The Palmer vils has two unbalanced RCA inputs. You can use astandard Y cable with 3.5 mm jack to connect to the headphones output on thelaptop. The vils sums both stereo channels to mono so that you only require onefree microphone input for the connection to the PA.
The Palmer vils is extremely easy to use and its passiveoperation means it does not need a power supply. A resistor network and atransformer, which simultaneously balances the signal, ensure an optimal adjustmentof level and impedance. This means that there is no interference even withlonger cable runs.
With the Palmer vils, you can be sure that yourpresentations are as crisp and clear as they sound at home.
