The RU-SM16A is the ideal choice in most applications where audio level metering is to be designed into a system or added to existing equipment. The RU-SM16A has two separate inputs. Each input may be individually calibrated for unbalanced consumer, balanced professional, 8 Ohm speaker line or constant voltage speaker lines (25 V, 70 V or 100 V). All connections are made using detachable terminal blocks. A rear-panel switch selects variable or fixed calibration for 25V, 70V, 100V and +4 dBu sources. In the "variable" position, front-panel multi-turn trimmers adjust the calibrated meter levels. Rear-panel switches allow the installer to set each meter individually for either peak or average audio level display. In stereo applications, either peak or average is typically selected. In monaural installations, it may be advantageous to feed the mono source to both meters, setting one for peak and the other for average. In either mode the upper three LEDs (+10, +14, +18) remain in the PEAK HOLD mode. The RU-SM16A uses bright LEDs for good visibility. Each channel input has a label area for identification of the source or function being metered. Features - Precision Audio Level Metering
