The D SERIES-PSP1 is part of the group of versatile wall-mounted products from Radio Design Labs. The standard mounting case can be directly fastened in North American
electrical boxes or in RDL International wall boxes.

APPLICATION: 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).

 Front-Panel Gain Adjustment
 Acoustically Optimized Decora Enclosure
 Fidelity Comparable to Larger Drivers
 Hemispherical Dispersion Mounted In Wall or Flat Surface
