Volume

The input sensitivity is adjusted (counte rc loc kwis e red uce s sensitivity) with the rear panel

mounted Volume control. Adjustment range is from -30dB to +6dB. Factory preset gain is +6dB. You may

need to adjust this to match the level of your monitors.

Adjustment

Low-Pass Frequency adjustment is performed through a coninuously variable adjustment. The range is from 50Hz to 130Hz. If you are

using the Subwoofer Line Outs for the monitors, you will want to place this at the 80Hz position (see additional information in the Installing Your Monitors section).

Phase Switch

Functionally, the Phase switch is a polarity inversion mechanism whose position affects the phase relation of the subwoofer output to the other speakers in your room. The proper switch position of 0 or 180 degrees depends on a number of variables. These variables include, the distance of the subwoofer from the listening position and monitors, as well as the

system's absolute polarity and the bass response of the room (refer to the Subwoofer Setup and Placement section in order to determine the correct switch position for your monitoring system and room).

Using the Ground Lift

Engaging the ground lift switch can sometimes reduce ground loop noise in your system. By providing an AC mains ground on the KRK10s and proper installation in a 'quiet studio' environment, the system is happily quiet. However, noise will be induced if the monitor is installed in less than desirable settings (i.e. audio cables run alongside power cables, behind

refrigerators, near florescent lighting, older buildings with bad wiring), or with certain equipment with lots of RFI (lap-top supplies, PCs, generator supplied AC lines). This is because there is a ground loop through the sub panel, mains wiring, source, and back to the subwoofer on Pin-1 of the Audio inputs. Ground currents traveling through this loop impose different voltages along the path at different gain stages within the circuitry, thus creating noises.

The Ground lift switch does not affect the AC mains/panel safety ground. It does not 'open' the connection thru Pin-1 to the panel, but increases the resistance (from zero ohms to one thousand ohms) to reduce the ground current and induced noises. Safety is not affected.

10S specifications

The KRK 10S is a powerful subwoofer designed specifically for professional studio and home audio applications, offering a compact solution for enhancing low-frequency performance in music production and mixing. Renowned for its exceptional sound quality, the KRK 10S is an ideal companion for KRK's renowned studio monitors, delivering deep, accurate bass that enriches both music and audio editing experiences.

One of the standout features of the KRK 10S is its impressive 10-inch woofer, which has been engineered to provide an expansive low-frequency response. This ensures that users can hear every nuance of their music, from the thundering lows of bass instruments to the subtle details in the mix. The subwoofer boasts a frequency response range of 29 Hz to 133 Hz, enabling it to reproduce the most profound bass frequencies with clarity and precision.

The KRK 10S also incorporates advanced technologies designed to optimize performance. One such feature is its built-in limiter, which helps prevent distortion and ensures that the subwoofer operates within safe limits even at high volume levels. Additionally, the subwoofer comes with a rear-panel volume control, phase switch, and a low-pass filter that allows users to tailor the bass response to their specific acoustic environment. This level of customization is crucial for achieving the best possible sound, as it enables audio professionals to match the subwoofer's output precisely with the main studio monitors.

Another significant characteristic of the KRK 10S is its robust construction. The cabinet is made from high-quality, durable materials that minimize unwanted vibrations and standing waves, enhancing the overall acoustic performance. The enclosure is designed to be both lightweight and sturdy, making it easy to transport while ensuring longevity in any studio environment.

The subwoofer features balanced XLR and TRS inputs, making it compatible with a wide range of audio interfaces and mixers. This versatility allows users to easily integrate the KRK 10S into their existing setups without any hassle.

In conclusion, the KRK 10S is a professional-grade subwoofer that excels in delivering deep, accurate bass for both studio and home listening applications. With its combination of exceptional sound quality, advanced technologies, and robust construction, the KRK 10S significantly enhances the audio experience for music producers, sound engineers, and audiophiles alike.
