AtlasIED TSD-MIX31RL x Mic/Line Mixer

Designed for reliable paging, monitoring and background music in security and AV environments, the AtlasIED TSD-MIX31RL 3x1 mic/line mixer delivers clear, low-noise performance where intelligibility matters. This compact pro audio mixer from AtlasIED accepts two balanced mic/line inputs plus a stereo RCA summing input, and offers switchable 24V phantom power for condenser microphones. Priority paging via VOX or contact closure on Input 1 mutes the designated channel for instant announcements—ideal for security control rooms, houses of worship, schools, and restaurants. A user-adjustable output limiter reduces clipping when mixing varying source levels, while a 125Hz 12dB/octave high-pass filter minimizes bass rumble and feedback. Remote level control capability lets you mount decorative wall plates for convenient local adjustment of the mix bus or a dedicated BGM input. With a 20Hz–20kHz response and energy-efficient aluminum construction, the TSD-MIX31RL is built for dependable 24V DC installations. Add this AtlasIED pro audio mixer to your surveillance, monitoring or paging system for crisp voice reproduction and simplified control.
