PRODUCT DESCRIPTION
The KPA series amplifiers are specifically designed for
fixed installations where high sonic performance and
ease of installation and management are paramount.
Each KPA amplifier is equipped with analogue and
K8 bus digital inputs. Used in conjunction with
Klein+Hummel K8 products, the KPA series amplifiers
provide a flexible, easy to manage signal and power
train for houses of worship, performance halls, arenas
and stadiums.
