AudioPack Pro delivers turnkey background music and paging infrastructure for commercial environments where consistent sound quality and ease of installation determine project success. The system pairs a FreeSpace IZA 190-HZ integrated zone amplifier with FreeSpace FS in-ceiling transducers, pre-matched for tonal consistency and reliable voice intelligibility across retail, hospitality, and corporate installations.

Class D amplification provides 90 watts at 70V or 100V, with dual channels supporting independent source routing and page priority. Built-in DSP presets align amplifier response to FreeSpace loudspeaker models, while Opti-Voice EQ optimizes paging clarity without external processing. Front-panel controls manage input selection, tone shaping, and master level; rear DIP switches configure amplifier mode and loudspeaker equalization for specific transducer models.

FreeSpace FS loudspeakers feature 2.25-inch woofers in engineered-plastic baffles with integrated steel backcans, designed for plenum-rated ceiling installations. Rotatable, removable logos and perforated steel grilles maintain visual discretion in customer-facing spaces. The system scales to business requirements with available package configurations and supports expansion when additional coverage zones are required.
