The FreeSpace® DXA 2120 digital mixer/amplifier provides signal processing, mixing, routing, paging and two-channel amplification all in one component for commercial applications such as conference spaces, retail stores, hotels and restaurants. The DXA 2120 digital mixer/amplifier offers three versatile operating modes. Host small events easily with up to four microphone inputs or music sources in mixer mode. Use dual mono select mode to create one or two listening environments in your facility — each with two separate program sources. For spaces where stereo music is part of the environment, the stereo select mode lets you create a single zone with two selectable program sources. Each operating mode is easily configured using the controls on the front panel, no external computer is required. Two wall-mounted user interfaces provide volume control or volume control with dual source selection. The DXA 2120 has six inputs: four selectable mic/line inputs, one page input and one direct input, which automatically overrides all other sources when a signal is detected. Opti-voice® paging ensures intelligible announcements at proper sound level in selected areas. The DXA 2120 digital mixer/amplifier has an integrated 24V DC backup power connection for added reliability and emergency paging during a main power outage. It is engineered and tested for business environments and backed by a two-year transferable limited warranty.
