RDL RU-SM16A - 2-Channel Audio Level Meter - 16-Segment LED Display

The RDL RU-SM16A is a precision 2-channel audio level meter designed for professional AV, broadcast, and sound reinforcement systems. It supports stereo or dual mono metering with selectable peak or average level display for each channel, making it ideal for both monitoring and system calibration.

Each input can be individually calibrated for line-level, 8 Ohm speaker-level, or constant voltage speaker lines (25V, 70V, 100V). A rear-panel switch allows selection between fixed and variable calibration modes, with front-panel multi-turn trimmers for fine adjustment. The bright 16-segment LED display provides clear visual feedback, with the top three LEDs operating in peak-hold mode at +10, +14, and +18dB.
