ACTIVE SINGLE PAIR RECEIVER

The RDL TX-TPR1A is an active single-pair receiver for RDL TP Format-A audio. It accepts a Format-A feed through an RJ45 input, allows switch selection of signal pair A, B, or C, and presents the chosen audio on balanced and unbalanced line outputs. The balanced connection uses a detachable terminal block, while the unbalanced connection uses RCA. An RJ45 Format-A loop output and three available power-connection methods give the receiver a clearly defined role in Format-A audio routing.

Ideal Use Cases

This model fits installations where an RDL TP Format-A source must feed equipment with a balanced terminal-block input or an unbalanced RCA input. Pair selection is useful when the required audio signal occupies pair A, B, or C of the incoming Format-A connection. The loop output also suits signal paths that need the Format-A connection to remain available after the receiver. Because power can be connected locally or delivered remotely through RJ45, the TX-TPR1A can be integrated according to the power arrangement established for the Format-A system.

Why Choose This Model

The TX-TPR1A combines pair selection, two line-output formats, an RJ45 loop output, and multiple power connections in one receiver. Its balanced output has a 150 Ω impedance and a specified level of +4 dBu, with a maximum of +22 dBu. The unbalanced RCA output has a 1 kΩ impedance and a -10 dBV output level. These two connection formats allow the selected Format-A signal to interface with equipment using either a detachable balanced terminal connection or an unbalanced RCA connection. A Power In indicator provides a visible indication of the receiver’s power status.

Installation and Integration

Connect the incoming RDL TP Format-A signal to the RJ45 input, then use the switch to select signal pair A, B, or C. Connect the balanced output through the detachable terminal block or use the RCA connector for an unbalanced output. The RJ45 LOOP OUT connection provides the Format-A loop-output path when it is required. Power can enter through the power jack, detachable terminal block, or RJ45 connection. The stated requirement is 24 Vdc at 35 mA plus connected loads. Recommended power supplies are the PS-24AS for USA use and the PS-24AX for international use; a power supply is not included. The receiver measures 3.17 inches wide, 1.76 inches high, and 2.06 inches deep. Its specified ambient operating range is 0° C to 50° C.

Performance Highlights

The specified frequency response extends from 10 Hz to 50 kHz within ±0.1 dB. THD+N is listed at less than 0.005%. Headroom above +4 dBu is greater than 18 dB, while common-mode rejection is greater than 80 dB from 50 Hz to 150 Hz. The published noise specification is less than 90 dB below +4 dBu. Together, these figures provide concrete response, distortion, headroom, noise, and rejection parameters for evaluating the receiver within an RDL Format-A audio system.

What Makes It Different

The defining feature of the TX-TPR1A is its switch-selectable access to any one of the three Format-A signal pairs. The selected pair can be delivered through a 150 Ω balanced terminal-block connection or a 1 kΩ unbalanced RCA connection, while the RJ45 loop output keeps a Format-A output available. Local and remote power options are supported through the power jack, terminal block, and RJ45 connections. This combination is contained in a chassis measuring 3.17 by 1.76 by 2.06 inches.

Final Assessment

For an RDL TP Format-A connection requiring access to signal pair A, B, or C, the TX-TPR1A provides a specific set of conversion and routing functions. It supplies balanced and unbalanced line-output connections, an RJ45 loop output, and local or remote 24 Vdc powering options. Its documented frequency response, low THD+N specification, headroom, and CMRR make its operating characteristics straightforward to assess before integration.
