RDL SF-TPRS12A Twisted Pair Format-A Line-Level Sender and Receiver

RDL SF-TPRS12A Twisted Pair Format-A Line-Level Sender and Receiver The SF-TPRS12A is a Format-A chassis that provides four three-pair audio sending sections and four three-pair audio receiving sections. Sending Section The SF-TPRS12A provides four audio sending sections compatible with RDL Format-A twisted pair products. Three +4 dBu balanced line-level sources may be connected to each section on a detachable terminal block. That section converts and transmits those signals on pairs A, B and C of the associated RJ45 connector. The SF-TPRS12A feeds all three signal pairs in the twisted pair cable. No other sending modules may be connected on the same cable with each RJ45 output. Receiving Section The SF-TPRS12A provides four audio receiving sections compatible with RDL Format-A twisted pair products. Each section receives up to three audio sources and provides three outputs corresponding to signal pairs A, B and C. A studio-quality buffer amplifier feeds +4 dBu balanced outputs through a detachable terminal block. The SF-TPRS12A features bridging inputs, allowing it to be connected to the LOOP OUT jack of other receivers. The bridging input circuits used in all FORMAT-A twisted pair receivers allow connection of up to 10 receiver outputs for each cable pair. Common The SF-TPS12A may be powered directly from a 24 Vdc power supply using either the power jack or the detachable terminal block. Local power connected to the module is also fed to all modules connected to the eight RJ45 jacks. Power for each RJ45 connector is protected against wiring faults by an automatically resetting fuse. Front-Panel green LEDs indicate valid module power on each RJ45 Key Features Four Separate Three-Pair Format-A Sender Sections Four Separate Three-Pair Format-A Receiver Sections Up to 24 Audio Channels, 12 Sender; 12 Receiver +4 dBu Balanced Audio Inputs and Outputs Local Audio Connections on Detachable Terminal Blocks Utilizes All Three Format-A Pairs Local Power Feeds all Modules Connected to RJ45 Connectors Wiring Fault Protection by Automatic Resetting Fuse Local Power Input on Terminal Block or dc Power Jack Green LED per Section Indicates Validity of Module Remote Power Studio-Quality Precision Active Balanced Circuitry Technical Specifications Sending Section Inputs (12)20 kΩ balanced Input Connection Detachable Terminal Block (Balanced) Input Level +4 dBu Bal.; +22 dBu Max Format-A Signal Pairs Used (3) A, B, C Output RDL TP Format-A Output Connection RJ45 Frequency Response 10 Hz to 50 kHz (± 0.1 dB) THD+N < 0.005% Noise Below +4 dBu < 90 dB Crosstalk < 85 dB (20 Hz to 20 kHz) Headroom above +4 dBu > 18 dB CMRR > 60 dB (50 Hz to 150 Hz) Receiving Section Inputs (4) RDL Format-A Input Connections RJ45 Format-A Signal Pairs Used (3) A, B, C (per section) Outputs (12) 150 Ohms Balanced Output Connection Detachable Terminal Block (Balanced) Output Level +4 dBu Bal. nominal, +22 dBu Max Frequency Response 10 Hz to 50 kHz (± 0.1 dB) THD+N < 0.005% Noise below +4 dBu < 90 dB Headroom above +4 dBu > 18 dB CMRR > 80 dB (50 Hz to 150 Hz) Common Power Connections (2) Power Jack; Detachable Terminal Block Ambient Operating Environment 32 Degrees to 131 Degrees F (0 Degrees C to 55 Degrees C) Power Requirement 24 Vdc @ 400 mA plus connected loads (1.6 A max) Dimensions (W x H x D) 8.74 x 1.68 x 5.78” (22.2 x 4.27 x 14.68 cm) Package Type Cardboard Box Package Dimensions 9.5 x 2.25 x 17.8 (24.1 x 5.71 x 17.8 cm) Shipping Weight 2.65 lbs WEEE weight 2.31 lbs Tariff code 8543.70.9960 Item Includes 1x SF-TPRS12A Line-Level Sender / Receiver
