The RDL RU-SM16A 2-Channel Audio Meter is a 1RU 1/3 rack module designed for precise metering of up to 2 channels of audio. The unit can be used for either 2 channels of mono metering or stereo operation and is designed to be integrated into new and existing setups.
Each channel utilizes sixteen LED indicator lights and may be individually calibrated for unbalanced consumer, balanced professional, 8 Ω speaker line, or constant voltage speaker lines (25V, 70V, 100V). The rear panel features terminal blocks for connections and variable or fixed calibration for 25V, 70V, 100V, and +4 dBu sources. When placed in the "variable" position, a set of front panel multi-turn trimmers can be used for calibrating the meter levels.
Each meter on the unit can be set to either peak or average audio level displays. In monaural applications, a mono source can be fed to two meters for both peak and average metering.
