Format-A Multiple Location Audio Sender-Black (Compatible with Guest Room Audio System)

The black RDL DB-TPS8A is a multiple-location audio sender designed for RDL TP Format-A systems and compatibility with guest-room audio systems. It accepts an unbalanced stereo source through a front-panel mini-jack and assigns the left channel to Format-A Pair B and the right channel to Pair C. Rear-panel RJ45 connections support Format-A output, signal and power pass-through, remote powering, and connection of additional TPS8A senders.

Ideal Use Cases

The DB-TPS8A is suited to guest-room audio systems and distributed audio installations that need local stereo source connections at multiple locations. Its front-panel input provides a convenient connection point for a nominal -10 dBV unbalanced source, while the rear RJ45 input accommodates additional TPS8A senders. Daisy-chain compatibility with single-pair senders further supports layouts in which multiple Format-A devices share a twisted-pair path.

The unit is especially applicable when the left and right source channels must occupy defined Format-A pairs. The left input feeds Pair B, and the right input feeds Pair C, making the channel assignment explicit for system planning and integration.

Why Choose This Model

The DB-TPS8A combines accessible source input, specified pair assignment, and RJ45 pass-through functions in a compact enclosure. Its front-panel mini-jack accepts stereo audio, while the rear-panel RJ45 architecture carries the Format-A signal and power connections. Signal and power pair pass-through allows compatible devices to remain connected along the same installation path.

• Unbalanced -10 dBV stereo mini-jack input
• Left channel assigned to Format-A Pair B
• Right channel assigned to Format-A Pair C
• Rear RJ45 input for additional TPS8A senders
• RJ45 signal and power pass-through
• Remote power through twisted-pair cable
• Daisy-chain support for single-pair senders

Installation and Integration

Source audio connects through the mini-jack on the front panel. The rear panel provides the RJ45 input and output connections used for the RDL TP Format-A signal path and power connection. The two specified Format-A signal pairs are Pair B for the left channel and Pair C for the right channel. Input impedance is listed as 10 kΩ for the unbalanced stereo input, and the input level is nominally -10 dBV with a +10 dBV maximum.

The module requires 24 Vdc at 30 mA and can receive remote power through twisted-pair cable via RJ45. The recommended power supplies are the PS-24AS for the USA and the PS-24AX for international use. Its enclosure measures 1.33 inches deep, 1.72 inches wide, and 4.11 inches high. The specified ambient operating range is 0° C to 55° C.

Performance Highlights

Studio-quality precision active balanced circuitry supports a frequency response of 20 Hz to 50 kHz within ±0.5 dB. Gain is specified at 12 dB, and headroom above +4 dBu is greater than 20 dB. THD+N is below 0.1% from 20 Hz to 50 kHz.

Noise is specified at less than -85 dB below +4 dBu. With as many as 10 TPS8A modules connected, the listed noise figure is less than -75 dB. Published crosstalk figures are less than 85 dB at 1 kHz and less than 75 dB from 20 Hz to 20 kHz. Together, these specifications define the module’s operating performance for Format-A analog audio distribution.

What Makes It Different

The distinguishing feature of the DB-TPS8A is the combination of a local stereo input and multiple-location expansion through its rear RJ45 connection. Rather than treating the stereo signal as an unspecified pair assignment, it directs the left and right channels to Format-A Pairs B and C. At the same time, signal and power pair pass-through, remote powering, and daisy-chain compatibility provide several integration options within a compatible RDL TP Format-A system.

Final Assessment

The RDL DB-TPS8A is a focused solution for adding an unbalanced stereo source to an RDL TP Format-A installation. Its -10 dBV mini-jack input, defined Pair B and Pair C routing, 12 dB gain, RJ45 pass-through, and remote-power capability directly address multiple-location audio distribution requirements. For guest-room audio systems or other compatible Format-A applications, it provides clearly specified audio, connection, power, and environmental parameters in a black enclosure.
