Product Description
RDL D-PSP1 Decora-Style Active Loudspeaker
Overview
The D SERIES-PSP1 is a compact active loudspeaker that delivers rich, detailed sound in Decora-compatible wall or chassis mounts. The input accepts either a -10 dBV unbalanced or a +4 dBu balanced signal on the rear-panel detachable terminal block. Amplification is provided by a high-efficiency Class D power stage with audio filtering tailored for crisp, pleasant audio clarity. The high-efficiency Class D output stage produces negligible heat for all levels of expected voice or music modulation. The amplified output level is controlled by a front-panel volume control. The -PSP1 includes an analog compressor/limiter that makes higher sound output levels possible without clipping.
The driver is constructed of materials found in premium larger speakers. The unique steel enclosure provides full baffling in a tightly sealed rigid structure. This produces sonic presence within an extended frequency range expected from larger speakers. Internal filtering rolls off out-of-band frequencies to reduce distortion and increase peak power capability. Dispersion covers a spherical area of nearly 180 degrees with the speaker mounted in a wall.
Models are available with grills in black (DB-PSP1), white (D-PSP1), gray (DG-PSP1) or stainless steel (DS-PSP1).
