Palmer RIVER vils - Channel merge line isolation box
We’ve all experienced the same thing before:
At home the sound was crisp and clear, but during the presentation it starts humming and buzzing, and there’s no time to find the cause.
This is where the Palmer vils comes into its own, reliably isolating the ground potentials between laptop, media devices and PA systems. (Peace returns, and you can once again focus fully on your presentation.)
The Palmer vils has two unbalanced RCA inputs. You can use a standard 3.5 mm jack Y-cable to connect to the laptop’s headphone output. The vils sums both stereo channels to mono, so you only need one free microphone input for the connection to the PA.
The Palmer vils is extremely easy to use, and its passive operation means it doesn’t require a power supply. A resistor network and a transformer, which also balances the signal, ensure optimum matching of level and impedance. This means there won’t be any interference, even over longer cable runs.
With the Palmer vils, you can be sure your presentations are just as crisp and clear as they sound at home.
