RDL RU-LB2 Line-Level Bi-Directional DANTE Network Interface

RDL RU-LB2 Line-Level Bi-Directional DANTE Network Interface The RU-LB2 modules are Dante audio network interface products compatible with line-level audio equipment inputs and outputs. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in commercial/industrial installations. The RU-LB2 converts two Dante audio channels to balanced line level. Each output provides +4 dBu balanced for a network digital audio level of -18 dBFS. The professional output directly interfaces with other professional and commercial equipment without the need for additional gain. Crosstalk is below the noise floor between all outputs across the entire audio spectrum. The noise floor is better than 80 dB below operating level. Key Features Converts Standard Line-Level Audio Sources to Dante Network Channels Line-Level Inputs Accept Unbalanced -10 dBV or Balanced +4 dBu Signals with > 18 dB Headroom Front-Panel Gain Adjustment with Dual-LED VU Meter for Each Audio Input Converts Two Dante Network Audio Signals to Balanced Line Level Line-Level Outputs Provide +4 dBu with > 18 dB Headroom Signal LEDs Indicate Audio for Each of the Received Network Signal Channels Interfaces Two Dante Inputs and Two Dante Outputs High Resolution 24 Bit Analog to Digital and Digital to Analog Conversion Legendary RDL Analog Filtering Enhances Superb Audio Performance LED Indicators Show Network Sync Status Normal or Hot-Standby Operation from PoE (Model RU-LB2P) Equipped for Rack Mounting or Surface Mounting Technical Specifications Network Connector RJ45 with Link and Speed indicators Digital Audio Ethernet Protocol Dante Transmission Rate 100 Mbps Sample Rates Supported 44.1 kHz, 48 kHz (default) Bit Depth Supported 24 bits Audio Operating Levels -18 dBFS = +4 dBu Line Inputs to Network Interface Section Inputs (2) Balanced, detachable terminal block Input Level for +4 dBu -16 dBu to +12 dBu, +22 dBu maximum Frequency Response 20 Hz to 20 kHz (- 0.5 dB) THD+N < 0.05% Noise below +4 dBu < -80 dB CMRR > 60 dB (50 Hz to 120 Hz) Crosstalk < 85 dB (20 Hz to 20 kHz) Headroom above +4 dBu > 18 dB Network to Line Level Interface Section Outputs (2) Balanced, detachable terminal block Output Level +4 dBu (nominal) Frequency Response 20 Hz to 20 kHz (- 0.5 dB) THD+N < 0.05% Noise below +4 dBu < -80 dB (output active); < -95 dB (outputs muted) Crosstalk < 85 dB (20 Hz to 20 kHz) Headroom above +4 dBu > 18 dB Indicators (11) Power In (1); Output Signal LEDs (2); Input Dual-LED VU Meters (4); Network Sys and Sync (2), Ethernet Link and Speed (2) Power Connections (2) Power Jack; Detachable Terminal Block Ambient Operating Environment 0 C to 40 C Power Requirement 24 Vdc @ 120 mA plus connected loads, or PoE (RU-LB2P) PoE (RU-LB2P) Class 0, IEEE 802.3af Dimensions 5.8" (15 cm) W; 1.7" (4.3 cm) H; 5.2" (13.2 cm) D Package Type Cardboard Box Package Dimensions 6 x 6 x 2.625 in.
