  • High-Gain Mic Preamps Deliver Clean, Low-Noise Amplification For Condenser And Dynamic Mics
  • Switchable Phantom Power Enables Condenser Microphone Use On Both Mic Inputs
  • VOX And Contact Closure Priority Muting Enables Hands-Free Paging Over Background Music
  • Variable Output Limiter Protects Downstream Equipment When Mixing Uneven Signal Sources
  • Remote Level Control Supports Wall Plate Adjustment Of Full Mix Or BGM Input Independently
  • High-Pass Filter On Each Input Reduces Low-Frequency Rumble And Feedback
  • Removable Phoenix Style Connectors And Security Covers Simplify Install And Prevent Tampering

The AtlasIED TSD-MIX31RL is engineered for installed audio environments where reliable mixing of microphone and background music sources is required in a compact, rack-mountable form factor. System integrators deploying paging, BGM, or distributed audio in commercial spaces will find the priority muting, remote level control, and Phoenix-style connectors directly aligned with the demands of permanent installation work.

Input flexibility covers two balanced mic/line channels with high-gain preamps suited for condenser and dynamic microphones, plus a stereo summing RCA input for line-level sources such as music players or zone amplifiers. The VOX and contact closure priority trigger on Input 1 mutes Input 3, enabling hands-free paging over background music without a separate controller. A variable output limiter protects downstream equipment when mixing sources with widely varying signal levels — a practical safeguard in multi-zone commercial installations.

Remote level control via the AAVC-10K or equivalent wall plate keeps user adjustments off the rack, and the 12 dB/octave high-pass filter at 125 Hz reduces low-frequency rumble on any channel. The unit draws only 60 mA, allowing multiple TSD devices to share a single TSD power supply — sold separately — which simplifies multi-room deployments and lowers rack overhead. Security covers on all front panel controls prevent unauthorized tampering in public-facing installations.
