Small Room? No Problem.

We all know that a subwoofer is an essential tool for production, mixing, and mastering. Without a subwoofer, there’s a good chance you’re not hearing what’s happening in the lowest octaves of your music. This can lead to out of tune kick drums and excessive low-end build up, which eats up your headroom and pushes your monitors harder than you need to. Of course, this is a two-way street. If you’re working in a smaller mix room, home studio, or post-production suite, the low-end can build up and cause more harm than good. This is where the Neumann KH 750 comes in.

Neumann KH 750 – Ultimate Low-End Control

Four Routing Modes, 8-Position Phase Control, Continuous Low-Cut, and Parametric Equalizer – the Neumann KH 750 has it all! Tune your low-end to your room with extensive controls to eliminate room modes and excessive low-frequency build up. The inclusion of Neumann.Control allows you to modify and control a wide range of features directly from your iPad. These include control over volume, preset levels, dim, mute all, logo brightness and more. Where Neumann.Control really shines is when integrating the KH 750 in your studio.

Integration with Any System

In addition to standard operating controls, the Neumann.Control app is incredibly useful when adding the KH 750 to your monitoring setup. If this is your first time installing a subwoofer, use the Guided Alignment tool to get the most from your sub. If, on the other hand, you prefer more hands-on control, switch over to Manual Alignment. This gives you total freedom over an 8-band fully parametric EQ, levels, and delays for each monitor or sub in your system. This is especially handy when working with multi-speaker setups, with support for up to 9 speakers or subwoofers. The inclusion of Digitial I/O and Network Connection via IP gives you ultimate flexibility for working in networked studios and production houses.

Legendary Neumann Quality

Of course, the Neumann KH 750 maintains the brand’s legendary build quality and sonic integrity. If you’ve ever used the Neumann U67 or KH 310 Monitors, you’ll know exactly what this means. Sturdy construction for years of use paired with reliably natural sound to get your mixes right where you need them. By taking the strain off of your main monitors, you’ll actually get more power, less distortion, and a longer lifespan from your monitoring system.
