KDX / KQX Series
Technical Data
The KDX / KQX series is a range of premium quality, compact size, high power amplifiers designed for live performance use as well as for permanent installations. The KDX / KQX models are based on Class D output circuit controlled by KIND modulator.Thanks to the high efficiency (more than 85%) Class D output circuit, dramatically reduce power distribution demands compared to older high power amplifiers. Other great advantages of this technology are: low heat dissipation, compact size, and KIND sonic integrity. A switchmode technology power supply replace a large heavy AC transformer with a highly efficient and light weight design. Front accessible dust filter for easy and fast unit cleaning. Three input connectors type, as Neutrik Combo™ (XLR and 1/4”jack) and 3-pin detachable Europlug (Phoenix), offers professional, semi-pro and installations connection way. KDX / KQX 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. Protection measures are enabled only when critical thresholds are passed or at start-up. Additionally, a soft-start circuit limits initial current draw when amplifier is turned on.The complete protection / warning suite includes: Short circuit, open circuit, thermal, RF protection, mains over / lower voltage, on/off muting, DC fault shutdown, clip limiter. Under normal use these features are inaudible and all protection methods are independent for each channel. The L.S.C. protection constantly monitors the current at the amplifier’s output. When load’s current exceed the amplifier’s limit, the output voltage will be automatically re-adjusted to keep the amplifier in a security condition. An additional circuit, with automatic reset, shut down the amplifier’s channel if a full short is made between a positive output and GND. The temperature management system sense the output devices temperature. In case of inadequate ventilation or overload, the hi-temp LED start to blinking and a level compensation process will be enabled. This protection safeguard the amplifier and prevent the definitive muting for overtemperature. The KDX / KQX series have an open input architecture and can have as option a Digital Signal Processing board (KIND DSP board-1) and a remote control that allows monitoring of all key amplifier parameters: power on/off, channel mutes, and channel solo functions.
KDX / KQX Benefits • Light Weight and power density: 8.5 kg - 2x1.9kW / 10kg - 4x1250W in a 2U chassis • Proven reliability • Two and four channel versions • Class D output circuit controlled by KIND modulator for high efficiency and sonic transparency • All channels bridgeable • Strong Reduction of kW/hr needed and power distributions demands, this is GREEN POWER • Low Thermal emission (BTU) • Clip Limiters • Two selectable input gains (26 dB, 32 dB) • Selectable low-freq. Filters (30Hz or 75Hz) • Tamper-proof optional DSP board • Balanced Neutrik Combo™ (XLR, 1/4 TRS) and 3-pin Europlug (Phoenix) Inputs per channel • Neutrik Speakon™ (with Bi-Wiring connection) Outputs • Stepped Gain controls Knobs • Continuously variable speed fans • Front accessible dust filter • Modular construction • Craftsmen built in Galliate, Italy • 3 year Warranty
