The TA-900MULTI is a perfect solution for residential as well as commercial installations in restaurants, pubs, shops, conferencing rooms, fitness clubs for both background music and voice playback systems.
A single TA-900MULTI amplifier allows to build a cost-effective multi-room audio installation and play different music in each of 4 zones (from 3 inputs) with independent volume and sound control for each, and to broadcast voice messages to selected zones simultaneously.
It can be used as part of an expandable ecosystem, allowing users to add additional amplifiers, active subwoofers and speakers to accommodate larger homes or more rooms.
High and constant power is delivered by an oversized, audiophile grade toroidal transformer.
The TA-900MULTI integrated amplifier offers the finest music performance at this price level and perfect matching with most speakers available in the market.
It utilizes advanced materials, state of the art engineering and innovate design by an international team of professional designers.
It delivers pure and distortion-limited power as well as rich sound performance with stunning accuracy, soundstage and sensational dynamics.
