Introduction ESR series Thank you for purchasing this KV2 Audio, ESR series system, consisting of the ESR2800 stereo controller/amplifier unit, two ESR212 speakers and optional variants of subwoofers. The ESR range has been developed for a particular niche in the market, where an all in one box is needed to give clear detailed reproduction over a wide area. The ESR212 and 215 are three way full range enclosures with wide dispersion characteristics.
Overview Features s Houses all signal processing and amplification as well as providing control for external subwoofer cabinet configurations. s External subwoofer is powered by the external subwoofer amplifier (VHD3200).
Getting started Cooling ESR2800 The ESR2800 Amplifier has a comprehensive cooling system featuring chassis sealed PCB board mounting and shock mounted, speed controlled fans. This means that the cooling system never drives air across PCB boards, connectors or components, ensuring prolonged electronic component lifespan and minimizing maintenance cycles.
Features Front panel 2 3 4 ESR2800 1 LIMITER SIGNAL PRESENT POWER ON / THERMAL (AUTO RESET) ESR2800 1) AC Mains Switch The ESR2800 Amplifier has a combination AC Main switch/circuit breaker on the front panel. If the switch shuts off during normal use, push it back to the ON position once. If it will not stay on you should take the unit to qualified service personnel to have it serviced. 2) LIMITER Yellow LED, indicates that the audio limiter has been activated.

Overview FULL RANGE MODULE The ESR212 is a dedicated Full Range System. Incorporating Patent Pending-Proprietory components, specifically matched to bespoke electronics. Exceptionally flat frequency response and Very High Defnition sound system. Emphasizes every detail and nuance of a performance and transfers the atmosphere to each and every audience member.
ESR212 Technology The ESR212 is a 3-way high output, active-driven, full range Loudspeaker module. It is designed as part of a sound reinforcement speaker system that includes the ESR2800 system control and amplification system. The ESR212 Loudspeaker system benefits from being designed exclusively to operate above 40 Hz. By optimizing the ideal operating band pass of each system component, the ESR212 can achieve extremely high output levels consistently and safely.
