Wohler 2U Level Monitor 8 aud chan, Deembed SD/HD-SDI - LM53-8M
LM3-8M
The LM53-8M is 2U level metering unit for visual monitoring of eight audio channels available for deembedding from digital HD-SDI or SD-SDI signals.
The unit features two unbalanced HD/SD-SDI inputs with an impedance of 75 Ω (ohm) and one re-clocked output, all on female BNC connectors.
The input accepts either SD-SDI or HD-SDI digital signals.
The input level is adjustable for gain via rear panel DIP switch modules.
Signal lock status is indicated by two separate LEDs on the front panel; one for SD-SDI signals and one for HDSDI signals.
The eight vertical audio level meters are 53-segment high-resolution tri-color (red/amber/green) LED bargraph displays with a wide dynamic range.
Bargraph meters in groups of four may be adjusted for a number of parameters, including Display Mode, Peak Hold, PPM Ballistics, Alternate Scales, and Phase Correlation via rear panel and internal DIP switch modules.
The Display Mode is factory set as a single segment PPM ‘dot’ above a VU bar; the color of each segment being fixed according to its position on the scale, but other modes are also selectable.
A recessed trimpot on the front panel is used to adjust the brightness of the eight LED bargraph displays
