OPTIMUS, the leading Spanish company in the design, manufacture and distribution of public address (PA), voice alarm (VA) and intercom equipment.
The PM-804A is a matrix mixer with 8 audio inputs and 4 audio outputs. The first four inputs have selectable sensitivity (microphone / line) and three band EQ, and the other four are with line sensitivity. All eight inputs are dynamically assignable to any output from the front panel, with individual volume and tone adjustment. In addition, the mixer can be remotely controlled from a four-zone microphone desk for live message delivery (PM-4Z), from wall-mounted controls that accept a microphone or line audio input (WP-1), or from pre-recorded message managers with zone selection and time control like SMM-8SA.
