The VHD LD4 is a four-channel line driver designed to maintain audio signal integrity over long cable lengths. As cable lengths between mixers and amplifiers increase, the length of the cable creates a high capacitance load that many mixers have difficulty in driving. The LD4 eliminates standing waves and signal impurities, resulting in the delivery of a high-quality audio signal no matter what the cable length. The VHD LD4 was built as a part of KV2 Audio’s VHD product philosophy - focused on delivering very high-definition audio. Each channel features an individual transformer-based power supply with insulated grounding. Circuitry is designed to provide excellent resolution of signal with very high dynamic content, as found in live sound applications.
