Model WTSD-MIX41K is a 4x1 Mic / line Analog Mixer that features 4-balanced microphone / line inputs and a balanced line output. Selection between mic or line level is done via dip switch on the rear panel. The high-gain mic inputs incorporate user-enabled phantom power for condenser microphones and a 120Hz low cut filter to eliminate unwanted low-frequency interferences. A global mute function can be triggered via local switch. Separate level controls for each input provide control for the audio mix needed. Input peak and signal indicators give visual reference to set the gain structure for maximum performance. The WTSD-PWBOB comes with each unit and features a balanced audio output with signal, mute, system priority and power LEDs and 12VDC logic output for remote system muting or power sequencing. Mic / line inputs are via a Phoenix-type connector on the rear of the WTSD. The WTSD-MIX41K can be converted into Dante Digital Network audio when interfaced with the optional AtlasIED TSD-DAC2i converter. The WTSD-MIX41K is designed to be used in conjunction with the AtlasIED WTSD-XLR4 input plate or with other XLR wall plates. The WTSD-XLR4 can also be used with the WTSD-COVER accessory for outdoor environments that require security.
