Flexible Inputs Optics - Use it to connect your TV, gaming system, or high-end audio device. The digital connection ensures a clean signal that can be controlled with a remote control. RCA- For connecting almost any device with analog audio output. Many televisions and other devices have RCA outputs. Those who don't, can use an inexpensive converter from the output to the RCA. S/PDIF - For connecting computers and home theater equipment. Like Optical, this is a digital input that guarantees pristine sound and can be controlled with a remote. XLR- For connecting professional audio equipment and connecting the MM-6 when used as a stereo pair. If you purchase these units as a pair, a 10-foot XLR cable is included. Sound Quality The MM-6 is acoustically identical to our best-selling studio monitor, the LP-6. Kali's studio monitors are used in the best studios around the world. Its precision, performance, and detail make it the first choice for Grammy Award-winning musicians and producers, film and television studios, and creators working with immersive formats such as Dolby Atmos. If you've listened to music, watched something on TV, or gone to the movies in recent years, you've likely heard something that was made on Kali Audio studio monitors. This means that when you listen to the MM-6s, you hear exactly what the creator intended. Nothing is suppressed, nothing is exaggerated. Everything is communicated with perfect clarity so you can immerse yourself in the experience and enjoy it to the fullest. Control and Connectivity The MM-6 features boundary EQ settings, allowing you to dial in the perfect sound whether the speaker is placed on a stand, desk, counter, or on a bookshelf. Whether your speakers are placed against a wall or in the center of the room, you can get clear sound with the push of a button. You can also add or remove bass and treble to further refine your sound. The included remote works with digital inputs, so you can easily control the speaker's volume even if the connected device doesn't allow you to turn it up or down.
