Decora-Style Active Loudspeaker-Format-A-White-Installer Level Adjust

The RDL D-PSP1AF is a white Decora-style active loudspeaker designed for compact installations using the RDL twisted-pair Format-A system. Its acoustically optimized enclosure combines a loudspeaker and 2-watt RMS audio amplifier in an ultra-compact format. The unit connects to a Format-A sender through an RJ45 twisted-pair connection and receives its operating power from the sender. Installer-set gain, selectable signal-pair routing, and integrated compressor/limiter protection support controlled system setup.

Ideal Use Cases

This model is intended for installations that require a compact, wall-integrated loudspeaker connected to an RDL Format-A sender. It can be mounted in a wall or on a flat surface, making it suitable where a Decora-style enclosure is preferred over a larger conventional loudspeaker. Hemispherical dispersion helps distribute sound from its installed position, while the white finish supports coordination with compatible architectural wall hardware.

The D-PSP1AF is particularly appropriate when the system design calls for installer-controlled level adjustment. Its gain control is a single-turn audio-taper adjustment set during installation rather than a prominent user-operated volume control.

Why Choose This Model

The D-PSP1AF concentrates amplification, signal reception, and sound reproduction into a compact Decora-format assembly. Its internal amplifier delivers 2 watts RMS, and the integrated compressor/limiter prevents clipping. RDL describes the enclosure as acoustically optimized, with fidelity comparable to larger drivers despite the unit's compact dimensions.

Format-A compatibility is central to this model. The loudspeaker accepts an RDL Format-A input through an RJ45 connector and can use signal pair A, B, or C. A rear-panel switch selects the required pair, giving the installer a direct way to match the loudspeaker to the system's twisted-pair signal assignment.

Installation and Integration

The D-PSP1AF connects to a compatible RDL Format-A sender using twisted-pair cable. It is powered from the RDL twisted-pair Format-A sender and requires 24 Vdc at 55 mA while idle or 100 mA maximum. The power connection is ground-referenced. Recommended power supplies listed for the system are the PS-24AS for the USA and PS-24AX for international use.

During setup, the installer selects Format-A signal pair A, B, or C on the rear panel and sets the required gain with the single-turn audio-taper adjustment. The enclosure supports installation in a wall or on a flat surface. It measures 4.12 inches high, 1.72 inches wide, and 2.27 inches deep, equivalent to 10.46 by 4.37 by 5.77 centimeters.

The specified ambient operating range is 0 degrees C to 40 degrees C maximum, with 20 degrees C recommended. These requirements should be considered when selecting the installation location and configuring the associated Format-A equipment.

Performance Highlights

The active loudspeaker has a nominal frequency range of 150 Hz to 20 kHz and a maximum sound pressure level of 81 dB. Its common-mode rejection ratio is greater than 80 dB from 50 Hz to 120 Hz. The compressor/limiter prevents amplifier clipping, while the acoustically optimized Decora enclosure is designed to provide fidelity comparable to larger drivers.

When mounted in a wall or on a flat surface, the driver provides hemispherical dispersion. This dispersion characteristic, combined with the compact enclosure, defines the D-PSP1AF as a focused solution for Format-A installations requiring sound coverage from a small wall-mounted assembly.

What Makes It Different

Unlike a passive wall speaker, the D-PSP1AF includes its own 2-watt RMS amplifier and operates as part of the RDL Format-A twisted-pair platform. It receives both its Format-A connection and operating power through integration with a compatible sender. Rear-panel A, B, or C pair selection adds routing flexibility, while the recessed installer-oriented gain adjustment keeps level configuration tied to system commissioning.

The combination of Decora dimensions, an optimized enclosure, clipping prevention, and hemispherical dispersion distinguishes the model from larger-format loudspeaker options. Its design prioritizes compact installation without separating the amplifier from the loudspeaker assembly.

Final Assessment

The RDL D-PSP1AF is a purpose-built white active loudspeaker for RDL Format-A systems. It offers a 2-watt RMS amplifier, RJ45 input, selectable signal-pair operation, installer-set gain, and compressor/limiter protection in a compact Decora enclosure. With an 81 dB maximum SPL and nominal 150 Hz to 20 kHz response, it provides clearly documented performance for compatible in-wall or flat-surface installations.
