K18

CLASS A/B WITH REFERENCE SOUND

The K Series amplifiers from KIND offer true professional quality, performance and road-proven reliability. K models are designed to work hard into 2 ohm loads. Every model suited for installation, performing musicians, and mobile entertainers. K amplifiers include a comprehensive set of features including inputs XLR/M, XLR/F for loop-through connectivity and outputs Speakon. All the models feature a Class A/B design. The K Series incorporates comprehensive warning and protection features to safeguard the amplifier and all connected loudspeaker drivers. Front-panel indicators give clear warnings when any potential problems are detected. The protections are inaudible under normal use and all protection circuitry are independent for each channel. The output devices has been protected by limiting the output current in case the load connected is too low (less than 1 Ohm) or the output is in short circuit.The temperature management system constantly monitors the heatsink temperature. If the heatsink reaches an abnormal temperature for inadequate ventilation the load will be disconnected. To protect the connected loudspeakers from DC, a DC detection system monitors independently both output channels. If DC of 5V or higher is present, (due to a fault in the power amplifier itself or due to applied DC on the input), the load will be disconnect immediately. The K series, with his aluminium front panel, have a professional look and a very strong chassis; KIND design and construction has been tested and refined over many years. The circuit board design is modular, because this type of construction greatly improves technical assistance.
