The WTSD-MIX41K is a 4x1 analog mic/line mixer featuring four balanced mic/line inputs and one balanced line output. Selection between microphone or line level is made by a DIP switch on the rear panel.  The high-gain microphone inputs feature user-enabled phantom power for condenser microphones and a 120 Hz low-cut filter to eliminate unwanted low-frequency interference. A global mute function can be activated via a local switch. Separate level controls for each input provide control for the required audio mix. Signal and input peak indicators provide a visual reference for setting 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 a 12V DC logic output for remote system muting or power sequencing.

Microphone/line inputs are via a Phoenix connector on the rear of the WTSD. The WTSD-MIX41K can be converted to Dante® digital network audio ^when connects 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 other XLR wall plates. The WTSD-XLR4 can also be used with the WTSD-COVER accessory for outdoor environments requiring security.
