KV2 Audio launches D Series amplifiers with on-board control and diagnostics

Globally recognised for its analogue engineering, KV2 has developed a range of D Series amplifiers featuring on-board control and diagnostics. Five new amplifiers – the ESR 3000D, ESR 2800D, ESP 2000D, SL3000D and VHD 3 – incorporate a range of topologies including a Class-AB design for enhanced high-frequency response, a unique high-current switching topology on low frequencies and hand-wound toroidal transformers that ensure consistent power delivery.

In terms of control, the D Series amplifiers offer the option to set up gains, operate mutes, configure the limiters, or select filter, EQ and bridge modes depending on the model. Supporting the increasing need of monitored loudspeaker systems in public spaces, the diagnostics section provides information on the temperature of heatsinks, mains voltage, real-time health checking and the output levels relative to limiting. Made in the Czech Republic, the amplifiers may be set up individually or in groups using the new KV2 Control & Diagnostics software tool, including saving and recalling presets or show files. Configuration and monitoring are accessible either via the front panel or remotely via any Windows or macOS device.

“Finally, our users can now benefit from control without compromise as well as real-time monitoring and system diagnostics – elements that are vital when running large systems,” commented KV2 Audio founder, George Krampera Sr. “Our customers no longer have to rely on third-party solutions which inevitably affect the sound. By embracing digital technology for control where it is suited, but maintaining the fastest, highest-quality analogue electronics for the audio path where it is needed, we have developed a revolutionary hybrid solution that offers user-friendly operation while maintaining the integrity of audiophile reproduction.”
