If you're going to perform live with a mixer, then you need something that handles like an instrument, and the Keith McMillen Instruments K-Mix is perfect for the job. This combination 8-in/10-out USB audio interface, touch-sensitive control surface, and standalone mixer puts premium sound quality and astonishingly flexible MIDI control in the center of your rig. High-quality, low-noise preamps? The K-Mix has two of them. How about processing and effects? From EQ to dynamics and even reverb, it's all there. And since there are no moving parts onboard the K-Mix, you can count on this control surface/interface to travel well and provide a lifetime of flawless performance. Keith McMillen Instruments K-Mix Performance Mixer/Interface at a Glance:
Virtually indestructible yet incredibly playable
Excellent preamps and connectivity options
DSP delivers onboard tone shaping power
Virtually indestructible yet incredibly playable
With its array of LED-backlit touch strips, buttons, and rotary zones, the K-Mix hardly resembles a conventional mixer or control surface, yet these tactile controls not only cover all of the functions you want to have on hand, they're far more responsive than traditional mechanical knobs and faders. For instance, you can jump between fader levels just by tapping on different locations on a touch strip, and sliding your finger on the rotary control zones is quicker than twisting a knob. And, since all control values are reflected by underlying LEDs, jumping from function to function is instant. What's more, these controls are virtually indestructible, so you can comfortably toss the K-Mix in your bag and go, without worrying about faders falling off or knobs caving in the PCB below. Excellent preamps and connectivity options
The connectivity packed into the K-Mix doesn't just sound great, it's incredibly flexible too. For starters, all of the audio I/O on the K-Mix is on balanced 1/4" TRS jacks, with the exception of the two muPre microphone preamplifiers, which feature combo jacks. These extraordinarily low-noise preamps offer full +48V phantom power and up to 60dB of gain, plus they include hi-Z instrument-level direct inputs as well. On the digital side, 24-bit AKM converters capable of up to 96kHz sample rates ensure that your sound remains pristine throughout processing, recording, or computer playback. What really caught the attention of the performing artists here at Sweetwater is that the K-Mix's full 8-in/10-out I/O is available without hooking it up to a computer, so you can leave your laptop at home and still take advantage of it extensive routing and processing options.DSP delivers onboard tone shaping power
Whether you're using it along with your DAW or in standalone mixer mode, the DSP processing onboard Keith McMillen Instruments' K-Mixgives you a whole lot of extra mileage out of your sound sources. For instance, each channel includes a 3-band semi-parametric EQ with up to 18dB of boost or cut per band. Fully adjustable compressor/limiters allow you to smooth out or punch up your sounds, and you can gate out noise if you need to. On top of that, there's a rich master reverb effect onboard, with dedicated sends for each channel. And, for added versatility on stage and in the studio, the K-Mix also includes four onboard surround-sound processing modes, which turn each of the rotary zones into surround panners.
