Palmer RIVER vils Channel Merge Line Isolation Box

Description:

We've all had the same experience before:

At home the sound was crisp and clean but during the presentation 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 safely isolates the ground potentials of the laptop, media devices and PA systems from each other. (Calm returns and the audience and you can concentrate fully on your presentation again.)

The Palmer vils has two unbalanced RCA inputs. You can use a standard Y cable with 3.5 mm jack to connect to the headphones output on the laptop. The vils sums both stereo channels to mono so that you only require one free microphone input for the connection to the PA.

The Palmer vils is extremely easy to use and its passive operation means it does not need a power supply. A resistor network and a transformer, which simultaneously balances the signal, ensure an optimal adjustment of level and impedance. This means that there is no interference even with longer cable runs.

With the Palmer vils, you can be sure that your presentations are as crisp and clear as they sound at home.

Features:

Noisless sound for presentations
For connecting a laptop or consumer audio device to a professional microphone input
