Gemini’s MM-2400 provides a feature-rich solution for DJs looking to incorporate a premium, cost-effective mixer into their existing rack setup. This 4-channel 19-inch mixer combines flexible connections, comprehensive features and preset sound effects in a 5U rackmountable design, making the MM-2400 a dynamic and powerful addition to any DJ rack or club installation.

Ideal for mobile DJs, wedding DJs, along with bar, restaurant and club installations, the MM-2400 boasts an extensive input/output section featuring seven line inputs, three microphone inputs and two phono/line convertible RCA jacks. In addition to a ¼-inch balanced Master output, the unit also includes Master, Record, Booth and Zone RCA outputs for connecting external equipment like amplifiers and recording devices.

To help you craft a unique and expert performance, the MM-2400 offers a host of professional features. Dual 10-band graphic EQ with LED indicators allow you to fully adjust your sound for varying situations, while dedicated Echo and Sound Effects sections give you the ability to get creative with adjustable delay and six pre-programmed samples like Applause, Scream and Scratch. A microphone EQ also lets you control the high and low frequencies of your mic signal and a convenient Talkover switch allows you to quickly decrease the main output so the microphone can be heard over the music.

Of course, a mixer’s effectiveness hinges on fine-tune control, which is why the MM-2400 provides controls for Zone, Booth and Cue volume, as well as Microphone, Channel and Master volume. A tight, smooth Rail Glide cross fader also allows you to mix evenly from one source to another, while a cross fader assignment rotary lets you designate which two channels will be controlled. And for even greater convenience, the MM-2400 includes a VU meter for monitoring decibel levels and a BNC lamp port for connecting a gooseneck lamp, ensuring that even in dark club settings, you can command your mix with ease and comfort.

If you’re looking for a reliable and professional yet easy-to-use addition to your rack, the MM-2400 offers an ideal way to elevate your performance with functionality and precise control – all while keeping your existing setup organized and streamlined.
