The VHD7000D is a high powered single channel rack-mounted subwoofer amplifier. The unit contains one 3500 W long-term RMS amplifier with a high current switching mode power supply, housed in a single 4U rack chassis. The design of its unique and innovative power management system enables the amplifier to deliver a short term power output of up to 14 kW, whilst operating at a modest consumption of 3.6 kW from a 16 A circuit.
The unit incorporates an over specified energy reservoir, enabling it to deliver peak output power beyond the capacity of the mains supply, and for longer durations than other comparable subwoofer amplifiers often quoting the same output power or more.
The unit acts as a standalone unit, or as a slave for other KV2 audio system and control amplifiers. The VHD7000D powers associated VHD subwoofer systems, as selected and is configurable from either the front panel, a web browser or by using KV2’s Control and Diagnostics Tool. The VHD7000D is equipped with variable gain, a low-pass filter, internal delay line, a notch filter and adjustable protection settings.
Specifically designed to drive all VHD, ES and SL subwoofer elements, with high power, exceptional control and advanced setup options utilising KV2’s Control and Diagnostics Tool
