KV2 Audio has announced the debut of the VHD7000D, a new power amplifier engineered to drive the company’s VHD, ES, and SL subwoofer elements, as well as third-party subwoofers, in large-scale events.
A power management system is designed to enable the VHD7000D to deliver short-term power stated as 7 kW, with peak output up to 14 kW, while operating at a consumption of 3.6 kW from a 16-amp circuit.
An integrated RMS limiter provides long-term protection for loudspeaker components by monitoring average power over time and analyzing thermal behavior to control temperature buildup. Pre-configured within the VHD7000D’s factory presets, it is designed to maximize SPL output, minimize thermal compression at high temperatures, and maintain natural sound dynamics, even during continuous high-output operation.
Another key feature is the tunable notch filter for resonance suppression. It prevents excessive cone excursion that causes distortion, reduced clarity, and shortened lifespan. Essential for touring or permanent installations, it delivers clear, precise, and impactful audio with a balanced low-frequency response and improved definition across the bass range.
The peak limiter provides additional protection, shielding loudspeakers from mechanical damage caused by excessive signal peaks and helping to ensure the cones remain within their safe range of motion. The amplifier also incorporates a high-power switching mode power supply circuit designed to enhance power delivery, onboard overdrive protection for more reliable performance, and remote configuration capability via KV2’s Control and Diagnostics Tool.
