Premium sound quality from a reliable, high quality Class-D amplifier designed to expand sound systems for loudspeaker installations

Expandable amplification allows for easy system expansion when coupled with a FreeSpace IZA 250-LZ or IZA 190-HZ integrated zone amplifier. The two amplifiers will function together as one system

Compact, lightweight design enables the FreeSpace zone amplifier to be placed out of the way—on a table, desk, counter, shelf or in an equipment rack using the optional Rack Mount Kit accessory

Two models available, 4/8 Ω or 70/100 V output, allow for better fit options for specific installations
