This is a strong buyer’s market for used installation mixer-amps, and the A$350 asking price is a genuine bargain. It sits well below the 25th percentile of A$404 from our recent AUD comps, with a median of A$614 and a 75th percentile of A$1,167, making this a clear value play.
The Australian Monitor ACM250 (likely the AMIS 250P variant) is a robust 6-channel mixer-amp delivering 250W into 4Ω plus 70/100V line outputs, ideal for commercial or multi-zone audio. These units are well-regarded for their reliability and flexible mic/line mixing, and a tested, working example at this price is a rare opportunity. Unless the listing hides missing accessories or untested channels, this is a buy-ready deal for anyone needing solid installation power.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Monitor Audio, a British hi-fi mainstay, traces its origins to 1972 when founder Mo Iqbal established the company in a modest factory near Cambridge, England. Starting with hands-on loudspeaker assembly in a garage-like setting, it quickly professionalized, moving to Rayleigh, Essex, in 1976 for in-house manufacturing. This heritage of meticulous British engineering has endured through expansions, including a 2004 shift of production to China while retaining design leadership in Essex, alongside strategic acquisitions like Roksan in 2016 and Blok in 2019.
The brand excels in loudspeakers across diverse categories, from high-fidelity two-channel stereo models to advanced home cinema systems, architectural installations, outdoor speakers, and lifestyle solutions. Signature innovations like the patented C-CAM Gold Dome tweeters, introduced in the 1980s and continually refined, define its sound. Complementing these are amplifiers, streamers, and integrated audio systems, reflecting a broad portfolio that prioritizes proprietary driver technologies and precise enclosure design over peripheral gear like turntables or headphones.
Positioned as a mid-to-high-end powerhouse, Monitor Audio commands respect for delivering audiophile-grade performance at accessible price points, blending relentless innovation with timeless British craftsmanship. Over five decades, it has solidified its status as a global juggernaut, appealing to discerning buyers seeking refined, dynamic sound without boutique exclusivity or vintage nostalgia.
