The KA7 350-Watt Class D Stereo Power Amplifier with DSP Controls by K-Array adds to its extensive feature set with a lightweight, efficient, and rackmountable build.

The KA7 has balanced XLR inputs with a switchable ground lift and a rotary input pad ranging from unity gain to infinity. It provides a USB output as well as dual RS485 jacks for PC connectivity. Built for daisy chaining, the KA7 has XLR link outputs for program signal, and a PowerCon output to link power. A dip switch on the rear panel allows up to 30 unique ID assignments for remote controlling arrays via software. The Speakon outputs provide solid, locking connections to speakers. An optical limiter automatically protects the system from dangerous peaks.

The K-Array KA7's most intriguing feature is, without a doubt, the built-in DSP input processing. The eDSP software installs on your Windows PC from the included CD-ROM and connects to the amplifier via USB or RS485. eDSP boasts real-time controls for EQ, dynamics, and signal level. The software's 4-band parametric equalizer is enough to manage a problem space, or just make simple sonic enhancements. The EQ, and a level control ranging from -infinity to +6dB, can be stereo-linked or controlled separately per input channel. The dual-channel compressor utilizes global settings for both input channels, providing dynamics control in addition to the amplifier's built-in limiter.

The KA7 by K-Array is designed for touring and installation applications in which a large amount of power and maximum flexibility are needed.
