Optimal Audio Zone 4P Four-Zone Powered Audio Controller

The Optimal Audio Zone 4P combines four-zone audio routing, digital signal processing and four integrated amplifier channels in a two-unit rack controller. Each amplifier channel is rated at one hundred watts into four or eight ohms. Bridged operation is specified at two hundred watts into a minimum eight-ohm load or for seventy-volt applications; this is not a native one-hundred-volt output on every channel. Two microphone inputs provide forty-eight-volt phantom power, alongside four stereo line inputs and two HDMI inputs for television or video sound. The browser-based WebApp supports configuration, loudspeaker presets, programmable settings and timed events. Four line outputs allow connections to additional amplification where required. This is the powered Zone 4P rather than the unpowered Zone 4. Compatible loudspeakers, audio sources, network access and any optional ZonePad controllers are separate. Speaker loading and bridged connections must follow the manufacturer installation instructions.
