The TX-TPS3C is a three-pair audio/video sending module compatible with RDL® Format-C twisted pair products. It is built in the versatile Max-TX series enclosure. The durable adhesives provided with the TX-TPS3C permit permanent or removable mounting. The TX-TPS3C may be rack or surface mounted with optional TX™ series accessories. The TX-TPS3C module features a BNC NTSC or PAL video input and two audio inputs, one for the left channel source and one for the right channel source. The unbalanced RCA jack audio inputs are designed to receive standard -10 dBV consumer level signals. Balanced +4 dBu audio inputs are provided through a detachable terminal block. The buffered video source is routed to pair A. The buffered left and right line-level inputs are routed to cable pairs B and C. This module drives all three Format-C cable pairs, so it is not equipped to receive inputs from other sender modules. The TX-TPS3C may be powered directly from a 24 Vdc power supply using the front-panel detachable terminal block. Local power connected to the module is also fed to all connected remote modules. The TX-TPS3C may be remotely powered through the twisted pair cable from any other module, signal distributor or RDL power inserter connected to the same twisted pair cable. Module power is indicated by a front-panel LED. RDL Format-C provides quality balanced video transmission over long distances, and features superior audio performance that rivals or exceeds shielded wiring. Design simplicity, ease of installation, unsurpassed flexibility, automatically fused power, exceptional hum rejection, low noise, and low distortion provide designers and installers the optimum choice in economical twisted pair products. | Inputs (5): | Video: 75 Ω; Audio (left and right): 10 kΩ unbal. and 10 kΩ balanced | | Input Connection: | Video: BNC; Audio: RCA Phono (unbalanced); detachable terminal block (balanced) | | Input Level: | Video: 1 V p-p; Audio: -10 dBV unbalanced or +4 dBu balanced | | Format-C Pairs: | A (Video); B (Audio Left); C (Audio Right) | | Gain: | Video: Unity; Unbal Line: 12 dB; Bal Line: Unity | | Output: | RDL TP Format-C | | Output Connection: | RJ45 | | Video Section | | | Video Format: | NTSC or PAL | | Video Bandwidth: | 10 MHz | | Audio Section | | | Frequency Response: | 20 Hz to 50 kHz (±0.5 dB) | | THD+N: | < 0.05% (20 Hz to 50 kHz); < 0.005% (1 kHz) | | Noise below +4 dBu: | < -95 dB | | Crosstalk: | Line to Line: < 90 dB (1 kHz); < 75 dB (20 Hz to 20 kHz);
