The RU-SM16D has four 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.\u003c\/p\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003cp\u003eRear-panel switches allow the installer to set each meter individually for either peak or average audio level display. In monaural installations, it may be advantageous to feed the mono source to two 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. In stereo applications, each channel, left and right, can display both peak and average values. Each of the four meters in the RU-SM16D may be operated separately to monitor four different sources.\u003c\/p\u003e\u003cp\u003eThe RU-SM16D uses bright LEDs for good visibility. Each input has a label area for identification of the source or function being metered.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePrecision Audio Level Metering\u003c\/li\u003e\n\u003cli\u003eDigital 16 LED String Display Indication\u003c\/li\u003e\n\u003cli\u003eFour Mono Meters or  Dual Stereo Metering\u003c\/li\u003e\n\u003cli\u003eLine-Level, Speaker-Level or 25\/70\/100 V Audio Input\u003c\/li\u003e\n\u003cli\u003eSelectable Fixed or Variable Calibration\u003c\/li\u003e\n\u003cli\u003eIndividual Channel Calibration Controls\u003c\/li\u003e\n\u003cli\u003eSelectable Peak or Average Metering\u003c\/li\u003e\n\u003cli\u003ePeak-Hold Display for +10, +14, +18 dB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable class=\"table1\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (4)\u003c\/td\u003e\n\u003ctd\u003eLine level or Amplified speaker level\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 40 k? balanced or unbalanced\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e0 dB Calibration\u003c\/td\u003e\n\u003ctd\u003eFixed or Variable (switch-selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFixed Input Level\u003c\/td\u003e\n\u003ctd\u003e+4 dBu (+4 switch settings, for 0 dB reading)\u003cbr\u003e25 V* (25 V switch settings, for 0 dB reading)\u003cbr\u003e70 V* (70 V switch settings, for 0 dB reading)\u003cbr\u003e 100 V* (100 V switch settings, for 0 dB reading)\u003cbr\u003e*Constant-voltage or low-impedance (4 Ohms, 8 Ohms) amplifier output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVariable Input Level Range\u003c\/td\u003e\n\u003ctd\u003e-24 dBu to +12 dBu (+4 switch settings, for 0 dB reading)\u003cbr\u003e 2 V to 90 V* (25 V switch settings, for 0 dB reading)\u003cbr\u003e4 V to 90 V* (70 V switch settings, for 0 dB reading)\u003cbr\u003e 5 V to 100 V* (100 V switch settings, for 0 dB reading)\u003cbr\u003e *Constant-voltage or low-impedance (4 Ohms, 8 Ohms) amplifier output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMetering Freq.
