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

Ideal Use Cases

The RDL DG-PSP1AF is a gray Decora-style active loudspeaker designed for RDL Format-A audio systems. Its ultra-compact enclosure makes it suitable for installations that require an in-wall or flat-surface loudspeaker without the dimensions of a conventional speaker cabinet. The unit connects to a Format-A sender using twisted-pair cable and receives power from the RDL twisted-pair Format-A sender. Rear-panel selection of signal pair A, B, or C allows the loudspeaker to be assigned to the required Format-A pair during installation. Hemispherical dispersion supports coverage from its installed position.

Why Choose This Model

This model combines a loudspeaker, a 2-watt RMS audio amplifier, and installer-adjustable gain in a Decora-format enclosure. The enclosure is acoustically optimized to deliver fidelity comparable to larger drivers while retaining its compact physical profile. A built-in compressor/limiter prevents clipping, helping the amplifier operate within its available output capability. The DG-PSP1AF is particularly appropriate when the installation already uses an RDL Format-A sender and requires a powered loudspeaker with a fixed, installer-defined output level. Its gray finish provides the specified color option for coordinated installations.

Installation and Integration

The loudspeaker accepts an RDL Format-A input through an RJ45 connection. It uses a switch-selectable Format-A signal pair, with A, B, or C selected from the rear panel. Gain is adjusted with a single-turn audio-taper control and is intended to be set by the installer. The unit can be mounted in a wall or on a flat surface.

The DG-PSP1AF measures 4.12 inches high by 1.72 inches wide by 2.27 inches deep, equivalent to 10.46 by 4.37 by 5.77 centimeters. Its power requirement is 24 Vdc at 55 mA while idle and 100 mA maximum, with ground-referenced power. The listed recommended power supplies are the PS-24AS for the USA and the PS-24AX for international use. The specified ambient operating range is 0° C to 40° C maximum, with 20° C recommended.

Performance Highlights

The integrated amplifier is rated at 2 watts RMS. Maximum sound pressure level is specified at 81 dB, while the nominal frequency range extends from 150 Hz to 20 kHz. Common-mode rejection ratio is greater than 80 dB from 50 Hz to 120 Hz. These published figures provide concrete parameters for evaluating the loudspeaker against the required listening level, frequency coverage, and Format-A system design. The compressor/limiter prevents clipping, and the acoustically optimized enclosure is designed to provide performance associated with larger drivers despite the unit’s compact dimensions.

What Makes It Different

The DG-PSP1AF is built around direct integration with the RDL Format-A platform rather than a general-purpose loudspeaker input. Its RJ45 Format-A connection, rear-panel A/B/C pair selection, and sender-powered operation create a focused installation workflow. The installer-set, single-turn audio-taper gain adjustment allows the output level to be established during setup. The combination of active amplification, clipping prevention, a Decora enclosure, and hemispherical dispersion consolidates the essential loudspeaker functions into one compact wall or flat-surface device.

Final Assessment

The RDL DG-PSP1AF is a purpose-built choice for a Format-A installation requiring a gray, ultra-compact active loudspeaker with installer-level adjustment. Its 2-watt RMS amplifier, 81 dB maximum SPL, nominal 150 Hz to 20 kHz frequency range, and selectable A, B, or C signal pair provide clearly defined integration and performance parameters. With an acoustically optimized Decora enclosure, built-in compressor/limiter, RJ45 connectivity, and power supplied from an RDL twisted-pair Format-A sender, it brings the required amplification and loudspeaker functions together in a compact installed format.
