How to use

Install the speaker into a standard ceiling cutout, securing the unit with the supplied mounting clamps or screws as applicable. Connect the speaker to the amplifier or paging system using correct polarity and appropriate cable gauge for the installation run. Set amplifier output and any zone-level controls to a moderate level, then adjust tone or EQ minimally to achieve clear speech and balanced background music. Verify secure mounting and test at typical listening positions to confirm even coverage and volume.

Recommendations

For best results, use the CSR-5B with low-impedance or matching commercial amplifiers rated for distributed audio; keep levels moderate for background music and ensure uniform speaker spacing to avoid hot or dead zones. Avoid exposing the speaker to direct moisture or extreme temperatures; for wet or outdoor environments select products with appropriate IP protection.
