Lowell 25LVC-RM 25W Mono Volume Control with Adhesive Dial Scale - Rackmount

The 25LVC-RM is a professional-grade mono autoformer attenuator volume control engineered for precise level adjustment in 25V and 70V distributed audio systems. Designed for reliability and installation efficiency, this rackmount-ready control delivers dependable performance in commercial sound environments such as paging systems, background music, and multi-zone audio applications.

With a 25-watt power rating, the 25LVC-RM provides smooth, consistent attenuation at 3 dB per step, including two 6 dB steps before the off position. This stepped attenuation design allows for accurate, repeatable volume adjustments while maintaining signal integrity across the speaker line. The autoformer-based architecture ensures low insertion loss and clean audio performance, making it suitable for both speech and music program material.

Installation is streamlined through Phoenix-style plug-in screw termination strips, enabling convenient pre-wiring and simplified servicing. The termination design accommodates wire up to 14-gauge, supporting robust connections for commercial-grade installations. An adhesive dial scale with a protective pocket is included, allowing integrators to insert custom paper labels for zone identification or user guidance. The unit is finished with a black rotary knob for a clean, professional appearance that integrates seamlessly into rackmount systems or custom panels.

Manufactured in the USA using U.S. and global components, the 25LVC-RM meets stringent compliance standards. It is ETL Listed and Trade Agreement Act (TAA) compliant, making it suitable for government and institutional projects that require certified products.
