4 Channel, Audio Analog Level Meter, 1RU
Product Description

Our LM Series of analog audio level meters are now available with a choice of BBC, DIN, Nordic and VU scales and “PPM Only” has also been added to the user selectable options. Wohler professional level meters are available with 26, 53 or 106 segment bar graphs, providing very high resolution and a wide (>70dB usable) dynamic range in increments as small as 1/2 dB across midscale.Our unique tri-color LED design means we can offer a variety of options such as phase correlation, peak hold, and alternate scales.
These units are optimized for viewing from a distance. Versions are available for analog sources, providing from 4 to 24 channels simultaneously depending on the model, and are available as 1RU or 2RU in-rack units. The standard display mode is set as a single segment PPM “dot” above a VU bar; each segment’s color is fixed according to its position on the scale. Level calibration for analog input versions may be set via dip switches to select one of four different calibration levels (for analog input types) via DIP switch settings.
Ideally suited for use in VTR bays, mobile production vehicles, teleconferencing installations, multimedia systems, satellite link and cable TV facilities and on-air radio studios.
