ALTO OEX600 600W Complete PA system

ALTO OEX600 Details

Alto reinvents the self contained PA system solution with the introduction of the Orient Express. Until now, self-contained PA systems have had limited acceptance among a wider range of performers. Often in the race to limit the size and cost of the overall system, not enough attention was paid to the performance of the individual components. Self-contained PA systems were often limited by low output power, inferior loudspeaker performance, underwhelming low frequency response and limited functionality of the mixer.

Alto set about solving the single system solution with the introduction of Orient Express systems. Available from an ultra-compact 400-watt four-channel package to a 1000-watt solution with 15-inch subwoofer, satellite speakers, 12-channel mixer with integrated DSP. There are Orient Express systems built for public speaking applications, for solo performers, duos, trios through to systems for small to mid size bands needing maximum performance from a single highly mobile packaged system.
