The EPAK™ 2500 is a four-way, active control and amplification system specifically designed for the KV2 Audio ES Series modular loudspeaker systems. It not only houses all signal processing and amplification but also controls allocation of power depending on the number of bass modules employed. Unlike other active speaker systems, the EPAK allows placement of critical (and heavy) electronics on stage - instead of inside the speaker modules (which may be flown or stacked where access is not possible.)
