The DD-RN31 is a complete wall-mounted Dante audio network interface. It features two XLR mic or line inputs, one stereo Mini-jack line input, left and right RCA jack inputs and one stereo Mini-jack line output on the front panels, plus two line outputs on a rear-panel detachable terminal block. The module is configured and adjusted using RDL CONSOLE or other network control software. The DD-RN31 fits a standard US dual-gang electrical box or an RDL WB-2 back box for installations in thinner European or equivalent walls. The DD-RN31 is PoE powered, and is available in multiple finishes with optional customized graphics.Main Features:Dante Network Interface for Four Audio Inputs and Four Audio OutputsOne Mini-jack, Two RCA Jacks and Two XLR Front-Panel InputsOne Mini-jack Front-Panel Output; Two Balanced Outputs on Rear-Panel Terminal BlockModule is Configured and Adjusted Using Network Control SoftwareQ-SYS Plug-In Available for Configuring in Q-SYS EnvironmentConverts Two Standard XLR Mic or Line Audio Sources to Dante Network ChannelsEach Input Gain is Selected by SoftwareMic Gain: 35 dB, 42 dB or 59 dBLine Gain: Unity or 12 dB48 V Mic Phantom (P48) Selected by SoftwareEach Mini-jack and RCA -10 dBV Input May Feed One or Two Dante Network ChannelsConverts Four Dante Network Audio Signals to Line LevelMini-jack -10 dBV Stereo Output from Two Specific Dante ChannelsRear Panel Balanced Outputs from Two Specific Dante ChannelsEach Rear Panel +4 dBu Output Equipped with Software Controlled Attenuator in 1 dB StepsStudio Quality, Low-Noise PerformanceHigh Resolution 24 Bit Analog to Digital and Digital to Analog ConversionLegendary RDL Analog Filtering Enhances Superb Audio PerformanceSpecifications:Network Connector: RJ45 with Link and Speed indicatorsDigital Audio Ethernet Protocol: DanteTransmission Rate: 100 MbpsSample Rates Supported: 44.1 kHz, 48 kHz (default)Bit Depth Supported: 24 bitsAudio Operating Level: -18 dBFS = +4 dBuReference Level: 0 dBFS = +22 dBuMic/Line Inputs to Network InterfaceInputs (2): XLR (female)Gain: Mic: 35 dB (LOW), 42 dB (MED), 59 dB (HIGH); Line: Unity (NORM), 12 dB (HIGH)Input Level (for +4 dBu/-18 dBFS): Mic: -31 dBu (LOW), -38 dBu (MED), -55 dBu (HIGH); Line: +4 dBu (LOW), -8 dBu (HIGH)Input Level (maximum): Mic: -14 dBu (LOW), -21 dBu (MED), -38 dBu (HI); Line: +23 dBu (LOW), +10 dBu (HIGH)Input Impedance: > 1.2 kPhantom Power: P48, 48 Vdc, software-selectableStandard for Phantom: IEC 61938: 2013Selectors per input (2): Phantom, Gain, software-selectableFrequency Response: 20 Hz to 20 kHz ( 0.5 dB)Equivalent Input Noise: < -128 dBu (59 dB gain); < -130 dBu A-WeightedNoise below -18 dBFS (20 to 20 kHz): Mic: < -88 dB (LOW), < -82 dB (MED), < -68 dB (HIGH); Line: < -88 dB (NORM), < -88 dB (HIGH)THD+N: < 0.1% (20 Hz to 20 kHz, +4 dBu/-18 dBFS)CMRR: > 65 dB (50 Hz to 120 Hz)Crosstalk: Below Noise Floor (20 Hz to 20 kHz at operating level, any input to any input, max. mic gain)Inputs (4): Mini-jack Stereo (2, L and R); RCA jacks (2, L and R)Input Level (for +4 dBu/-18 dBFS): -10 dBV nominalInput Level (maximum): +8 dBVInput Impedance: > 50 kSelectors: Stereo (L and R)/Mono (summed), software-selectableFrequency Response: 20 Hz to 20 kHz ( 0.2 dB)Noise below -18 dBFS (20 to 20 kHz): < -85 dBCrosstalk: < -85 dB (1 kHz); < -65 dB (L into R, R into L, 20 Hz to 20 kHz)THD+N: < 0.05% (20 Hz to 20 kHz, +4 dBu/-18 dBFS); 0.01% at 1 kHz (typ)Outputs (4): Balanced, detachable terminal block (2); Unbalanced, Mini-jack (2, L and R)Output Level (operating): +4 dBu (nominal) balanced, software adjustable in 1 dB steps; -10 dBV (nominal) unbalancedOutput Level (maximum): +22 dBu balanced; +8 dBV unbalancedOutput Impedance: 150 balanced, 100 unbalancedFrequency Response: 20 Hz to 20 kHz ( 0.5 dB)THD+N: < 0.05%Noise: < -88 dB (bal., below +4 dBu); < -106 (bal., below +22 dBu); < -90 dB (unbal., below -10 dBV)Crosstalk: < -70 dB (bal., 20 Hz to 20 kHz); < -80 dB (unbal., 20 Hz to 20 kHz)Indicators (4): Ethernet Link and Speed (2, rear panel); Sync and Power (2, front panel)Ambient Operating Environment: 0 C to 40 C; 30 C maximum recommendedPower Requirement: PoE Class 0, IEEE 802.3afSpecification Conditions: Gain/Level: 1 dB; Source termination: 150 ; A to D values measured in digital domainDimensions: 3.52" (8.94 cm) W; 4.11" (10.44 cm) H; 2.09" (5.31 cm) DPackage Type: Cardboard BoxPackage Dimensions: 3.625 x 4.625 x 2.125 in.Shipping Weight: 0.92 lbs.WEEE weight: 0.765 lbs.Tariff code: 8543.70.9100
