RDL FP-MX3R Remote Controlled Line-Level Mixer

Keep audio control centralized and secure with the Radio Design Labs FP-MX3R Remote Controlled Line-Level Mixer — ideal for security, surveillance, paging and commercial AV installations. This pro audio mixer provides three channels of VCA-controlled mixing with per-input gain trims and a full 20 Hz–20 kHz frequency response, delivering clean, consistent level control for microphones, music sources, or paging equipment. Balanced and unbalanced inputs plus both balanced and dual unbalanced outputs make connectivity to amplifiers and monitoring systems straightforward. Remote control via RJ45 twisted-pair lets operators adjust levels from a control location while the mixer stays locked in a rackroom, and audio-detect outputs automate amplifier muting and energy savings. The FP-MX3R runs on 24 V DC, mounts easily in a FLAT-PAK rack space, and includes a visible dual-LED VU meter for quick level checks. For integrators and system managers needing reliable remote volume control in security or AV monitoring environments, the FP-MX3R streamlines installation and operation — contact us to specify it for your next project.
