Atlas Sound MIX42RT – 4x2 Mic/Line Mixer Priority Sense Remote Control

Product Overview

The Atlas Sound MIX42RT is a compact 4x2 mic/line mixer designed for applications where paging, priority music override, and remote input selection are required in meeting rooms, digital signage environments, and commercial audio installations. With one balanced mic/line input and three unbalanced stereo 3.5mm line inputs, this priority sense mixer handles multi-source scenarios in conference rooms, luxury suites, and distributed audio systems. Remote level control compatibility with the WPD-VC10K wall plate and built-in VOX/contact closure priority triggering make the MIX42RT a practical signal routing solution for installations requiring hands-free or automated source management.

Product Description

The TSD-MIX42RT accepts one balanced mic/line signal via a removable Phoenix-style connector and three stereo 3.5mm unbalanced inputs, supporting stereo or mono output configurations. Switchable 24VDC phantom power enables use of condenser microphones on the mic input without an external preamp. The high-quality, low-noise internal mic preamp delivers 46 dB of gain with a flat frequency response from 20 Hz to 20 kHz (+/- 1 dB) and a signal-to-noise ratio of 78 dB mic-to-line and 85 dB line-to-line. A 12 dB/octave high-pass filter at 125 Hz on the mic input reduces bass rumble and low-frequency feedback in speech-oriented applications. Priority paging is triggered via contact closure or VOX on Input 1, which automatically mutes Inputs 2, 3, or 4 as assigned. The variable output limiter reduces clipping and distortion when mixing sources of varying levels. The WPD-MIX42RT companion wall plate (sold separately) provides remote source selection and volume control at the room level, and connects via an 8-conductor interface. The optional AAVC-10K or WPD-VC10K wall plate control provides remote master mix or individual input level adjustment. Power is supplied externally at 24VDC, 60mA. Dimensions are 1.5" x 4" x 5.2" and weight is 13 oz. Certified RoHS compliant with a 3-year limited warranty.

Key Features

• Priority Paging via VOX or Contact Closure — Input 1 can trigger automatic muting of Inputs 2, 3, or 4, enabling clear priority announcements without manual intervention.
• Switchable 24VDC Phantom Power — Powers condenser microphones on the balanced mic input, eliminating the need for an external preamp or phantom supply.
• 12 dB/Octave High-Pass Filter at 125 Hz — Defeatable filter on the mic input reduces low-frequency feedback and background rumble in voice applications.
• Remote Level Control — Compatible with AtlasIED WPD-VC10K or AAVC-10K wall plate for remote master or per-input level adjustment.
• Variable Output Limiter — Prevents clipping and distortion when mixing sources with widely varying signal levels.
• Stereo or Mono Output — Flexible output configuration supports both stereo and mono distributed audio system wiring.
• WPD-MIX42RT Wall Plate Companion — Optional decor-style wall plate provides in-room source selection and volume control via an 8-conductor interface.
• RoHS Certified — Compliant with environmental requirements for commercial AV installations.

Frequently Asked Questions

Q: Is a power supply included with the MIX42RT?

A: No. The MIX42RT requires an external 24VDC, 60mA power supply, which is sold separately.

Q: Can the mixer be used without the WPD-MIX42RT wall plate?

A: Yes. The TSD-MIX42RT operates as a standalone mixer. The WPD-MIX42RT decor wall plate is an optional accessory that adds in-room source selection and volume control.

Q: How does VOX priority paging work?

A: When a signal above the VOX threshold is detected on Input 1, the mixer automatically mutes the assigned inputs (2, 3, or 4), allowing the priority signal to pass clearly without manual intervention.

Q: Can the MIX42RT support condenser microphones?

A: Yes. The balanced mic input includes switchable 24VDC phantom power, enabling use of condenser microphones without an external phantom supply.

Q: What is the maximum output configuration?

A: The MIX42RT supports 4 inputs summed to 2 outputs, configured in either stereo or mono, suitable for connection to a downstream amplifier or zone controller.

Q: What wall plate controls are compatible for remote level adjustment?

A: The AtlasIED WPD-VC10K and AAVC-10K decorative wall plate controls connect to the MIX42RT for convenient remote adjustment of the master mix or individual input levels.
