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

The RDL DB-PSP1AF is a black Decora-style active loudspeaker designed for RDL Format-A audio systems. Its ultra-compact enclosure combines a 2-watt RMS audio amplifier, installer-set gain, and an integrated compressor/limiter that prevents clipping. The loudspeaker receives its audio input through an RJ45 connection and can be powered from an RDL twisted-pair Format-A sender, supporting a streamlined connection between the sender and loudspeaker.

Ideal Use Cases

This model is suited to fixed installations that require an active loudspeaker in a Decora-format opening or on a flat surface. It is especially appropriate when the system already uses an RDL Format-A sender and twisted-pair cabling. Because gain is set by the installer, the DB-PSP1AF works well in applications where the listening level should be established during setup rather than adjusted from the front of the loudspeaker.

The compact form factor also makes it useful where a larger loudspeaker enclosure would be difficult to accommodate. RDL describes its fidelity as comparable to larger drivers, while the acoustically optimized enclosure and hemispherical dispersion support coverage from an in-wall or flat-surface mounting position.

Why Choose This Model

The DB-PSP1AF integrates the loudspeaker and a 2-watt RMS amplifier into one Decora-style assembly. This removes the need to specify a separate local amplifier for the loudspeaker. Its compressor/limiter prevents clipping, helping the compact amplifier manage incoming audio without clipped output.

A rear-panel switch selects Format-A signal pair A, B, or C. This gives the installer control over which available pair the loudspeaker uses. The single-turn audio-taper gain adjustment is also located for installer setup, allowing the operating level to be established as part of system commissioning.

Installation and Integration

The loudspeaker accepts an RDL Format-A input through an RJ45 connection and connects to a Format-A sender using twisted-pair cable. It can receive power from the RDL twisted-pair Format-A sender. The specified power requirement is 24 VDC at 55 mA while idle and 100 mA maximum, with ground-referenced power. Recommended power supplies are the PS-24AS for the USA and PS-24AX for international applications.

The enclosure can be mounted in a wall or on a flat surface. Overall dimensions are 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°C to 40°C maximum, with 20°C recommended.

Performance Highlights

• 2-watt RMS integrated audio amplifier
• Maximum sound pressure level of 81 dB
• Nominal frequency range of 150 Hz to 20 kHz
• CMRR greater than 80 dB from 50 Hz to 120 Hz
• Compressor/limiter designed to prevent clipping
• Hemispherical dispersion when mounted in a wall or on a flat surface

These specifications define a compact active loudspeaker focused on Format-A system integration. The frequency range extends to 20 kHz nominally, while the 81 dB maximum SPL establishes the model’s stated output capability. Its greater-than-80 dB CMRR specification applies across the stated 50 Hz to 120 Hz range.

What Makes It Different

The DB-PSP1AF combines several installation-oriented functions in a single Decora-format product: an active loudspeaker, Format-A receiver connection, selectable signal-pair assignment, installer-adjustable gain, and clipping protection. Its ability to obtain power from an RDL Format-A sender further distinguishes it from a conventional passive loudspeaker that requires a separate amplifier connection.

The rear-panel A, B, or C pair selection makes the product specifically adaptable to the Format-A signal structure. At the front of the installation, the acoustically optimized Decora enclosure maintains an ultra-compact footprint while providing the stated hemispherical dispersion.

Final Assessment

The RDL DB-PSP1AF is a focused solution for adding a black, Decora-style active loudspeaker to an RDL Format-A system. Its RJ45 input, sender-powered operation, selectable signal pair, and installer-set gain simplify integration within its intended platform. A 2-watt RMS amplifier, compressor/limiter, 81 dB maximum SPL, and nominal 150 Hz to 20 kHz frequency range provide clearly defined performance in a compact in-wall or flat-surface enclosure.
