HS Series speakers are the standard in studio monitors, trusted for many years by the worlds top audio engineers, producers, and artists. Now Yamaha has redefined their essence in a compact housing. The HS3 and HS4 are powerful tools to help create a wide range of audio contentfrom music production to video editingthat meets the expectations of creators who have limited space but do not want to compromise on monitoring quality. The HS3 and H34 studio monitors embody Yamaha's legacy of design excellence. No detail has been overlooked. Inside are carefully selected parts such as a high-performance class-D amplifler, a highly resilient MDF cabinet, as well as woofers and soft-dome tweeters that deliver a pure sound faithful to the source - despite their small size. Additionally, the proprietary "Twisted Mare Port" technology delivers crystal-clear bass with minimal turbulence noise, The result is outstanding resolution, sound image, and depth with a flat response across all bandwidths without any colouring of the original sound. The sound produced by speakers can sometimes be affected by the surrounding environment. The rear panels of the HS3 and HS4 are equipped with ROOM CONTROL and HIGH TRIM functions that allow you to make adjustments to achieve the ideal sound for any environment, such as reducing the unneeded, exaggerated low-end that can often occur when speakers are placed next to walls. The rear panel of the HS3 and HS4 is equipped with combination XLR/TRS phone, RCA, and stereo mini connectors, allowing you to connect to a wide range of equipment such as computers, audio interfaces, audio mixers, and electric instruments. The most commonly used featurespower button, volume knob, and headphone connectorare located in the front for easy access. The compact size of the HS3 and HS4 was made possible thanks to the highly efficient class-D amp. Using one amp for two speakers has enabled Yamaha to both reduce the weight of the speakers and simplify the cable connections. They take up little space even in a small bedroom studio, and are easy to take with you on the road.
