Microphone mixer (PZA )

4x2 Mic/Line Mixer with Priority Sensing and Remote Control

The AtlasIED TSD-MIX42RT 4x2 mic/line mixer is ideal for applications where paging, priority music override, and/or remote input selection with level control is required. Use it alone or in conjunction with amplifiers in meeting rooms, digital signage, luxury suites, and other applications requiring versatile stereo or mono mixing control of multiple sources.

The unit includes a balanced microphone/line input via a removable Phoenix-style connector and three 3.5mm stereo inputs. Switchable phantom power is provided for the microphone input to facilitate condenser microphones. High-quality, low-noise internal microphone preamps ensure clarity and quiet operation without unwanted coloration. A 12 dB/octave high-pass filter at 125 Hz is also available on the microphone input to minimize bass rumble and low-frequency feedback.

The TSD-MIX42RT can be used in conjunction with a WPD-MIX42RT decorator-style wall plate designed for remote activation of the TSD-MIX42RT mic/line mixer. The WPD-MIX42RT features a sliding audio source selector as well as a source volume control. The unit includes an LED indicator to indicate which source is selected and whether it is active. The unit fits into a single-gang electrical receptacle and utilizes an 8-conductor interface connection that includes a removable 4-position Phoenix connector and dual 2-position Phoenix-style connectors. When connected to the TSD-MIX42RT and Juke Box Override, any call made through the system will override the selected source so the call can be heard clearly.

Priority paging can be achieved by contact closure or VOX trigger on Input 1 which will mute Inputs 2, 3 or 4 (assignable). The remote level control feature allows the use of the AtlasIED AAVC-10K or WPD-VC10K decorative wallplate control for convenient remote adjustment of the entire master mix bus or inputs 1, 2, 3. A variable output limiter provides system protection by reducing clipping and distortion, which is especially useful when mixing microphone and/or line sources with different volumes.

The unit requires a power supply sold separately to operate properly; multiple TSDs can be powered with one power supply depending on current requirements. Click here to use the TSD Power Calculator and find the right power supply for your application.
