The Palmer vils at a glance

At home the sound was clear and clean, now in the venue it hums and chirps over the speakers. There is no time for troubleshooting. The Palmer vils, a passive mono merge line isolation box that separates the ground potentials of laptop respectively media devices and sound system, provides a reliable remedy.

The Palmer vils has two unbalanced RCA inputs. To connect to the headphone output of the laptop, you can use a standard Y-cable with a 3.5 mm jack plug. The vils sums both stereo channels to mono, so you only need one free microphone input for connection to the sound system.

The Palmer vils is extremely simple to use. Due to its passive operation, it does not require a power supply; a resistor network and a transformer, which simultaneously balances the signal, ensure optimum adjustment of level and impedance. This means that no interference occurs even with longer cable runs.

With the Palmer vils, you can finally rely on your presentations sounding as clear and clean in the lecture hall as they do at home.
