Tonelux VU4 VU Meter

The Tonelux model VU4 metering module allows inserting a metering system between any signal in the Tonelux modular setup. The VU4 will not load the signal significantly, as it has an input impedance of over 100K. With the ability to accept two separate signals from two sources, the VU4 can be used as a “Source/Tape” metering system with external control over the switching of all meters.
