53-Segment LED Bargraph Specifications
Standard 53-Segment Bargraph Analog Scale
53-Segment LED Bargraph Description
The 53-segment type of tri-color LED bargraph display has a total length of 2.24" (56.8 mm) and uses relatively
small segments. This high resolution segment size is easy to accurately monitor, visually, for distances up to six
feet (1.8 meters). Segment size is 0.158" (4 mm) x 0.04" (1 mm). Segment pitch is .039" (0.99 mm).
Each LED bargraph display section visually indicates the dynamic changes within the audio signal source(s) being
monitored. Each bargraph section is always comprised of two vertically oriented bargraph "trees", representing
two channels, with the scale markings located between the two "trees". The VAMP-24 uses two of these bargraph
pairs to monitor a total of four channels at a time. All bargraph LED segments are of the tri-color type (green,
amber, red). Ballistics for these meters are factory set to display a single floating PPM 'dot' (continuous decay of
20dB in 1.5 seconds) above a VU bar; each segment's color being fixed according to its position on the scale.
Level gain is set at +4 dBu. Dynamic range for these 53-segment meters is 65dB.
