Model WTSD-MIX31K is a 3x1 Mic/line/Aux /Bluetooth Analog Mixer that features a balanced microphone/line input and an auxiliary 3.5mm and Bluetooth summed input with a balanced line output. The WTSD-MIX31K utilizes commercial grade Bluetooth technology featuring ultra-low noise levels, long range connectivity, no auto-connect and a quick disconnect bump feature. The Bluetooth Discovery ID name can be customized using the installers renaming app. Selection between mic or line level for the XLR input is done via front panel switch, accessed thru a pinhole. The high gain mic inputs incorporate user enabled phantom power for condenser microphones and a 125Hz low cut filter to eliminate unwanted low frequency interferences. A local mute button mutes output to the bus and a system priority button can mute building wide BGM systems to isolate the room. An adjustable VOX feature allows for AUX input background audio to be muted when announcing is present. The AUX input is a stereo 3.5mm jack and is electronically summed to achieve the best audio performance. Separate level controls for each input provide control for the audio mix needed.

The WTSD-PWBOB comes with each unit and features a balanced audio output with signal, mute, system priority and power LEDs and 12V DC logic output for remote system muting or power sequencing.

The WTSD-MIX31K can be converted into Dante® Digital Network audio when interfaced with the optional AtlasIED TSD-DAC2i converter.
