Introduction Welcome! Thank you for making the Alesis iMultiMix 8 USB a part of your studio. Since 1984, we've been designing and building creative tools for the audio community. We believe in our products, because we've heard the results that creative people like you have achieved with them.
Introduction About the iMultiMix 8 USB The iMultiMix 8 USB mixer is the latest in the large family of Alesis audio mixers. We’ve come a long way since the 1622 mixer we first built in 1989. Since that time audio technology has grown in leaps and bounds, pushing up quality and driving down prices.
Chapter 2: A Tour of the iMultiMix describes the iMultiMix 8 USB piece by piece. This chapter also features diagrams of the mixer to help you find each component as you read about it.
We realize that some of you who have purchased the iMultiMix 8 USB are fairly new to the art of mixing, and we’ve written this manual with that in mind. We also designed the iMultiMix 8 USB to be both powerful and easy enough to use that even a beginner can quickly pick up the basics.
Getting Started Hooking up the iMultiMix 8 USB This diagram will help you get the iMultiMix 8 USB hooked up and ready to go. The equipment you use depends on personal preference and on whether you’re performing live or recording.
Getting Started Using Proper Cables When connecting instruments and other equipment to the iMultiMix, it’s important that you use the appropriate types of cables. Here are some simple but important guidelines: For the mic inputs, use XLR cables. For the line inputs and all other 1/4” connections, use 1/4” mono TRS cables.
Patchbay At the rear portion of the top of the iMultiMix 8 USB, you’ll find the patchbay. This is where you plug in instruments, signal processors, multitrack recorders and other devices. In the following paragraphs, we tell you all about the inputs, outputs, switches and knobs you see in this section of the mixer.
A Tour of the iMultiMix USB Line Inputs (Channels 5 – 8) Unlike channels 1 – 4, the line inputs on channels 5 – 8 are stereo inputs that have left and right inputs. If you’re using one of these channels as a mono input, plug your instrument into the left input.
A Tour of the iMultiMix USB Channel Strips The eight channel strips are virtually identical to each other, with the only difference being that channels 1 – 4 are mono and channels 5 – 8 are stereo. Each channel strip contains the following components. Level Control The level control knob controls how much of the signal from the mic or line inputs is sent to the channel.
A Tour of the iMultiMix USB The iMultiMix gives you three bands of EQ per channel. Using these knobs, you can tailor the channel’s signal by boosting some frequencies and cutting others. The LO and HI controls are shelving controls with fixed frequencies of 75 Hz and 12 kHz respectively.
AUX RETURN A. EFFECTS / AUX RET B LEVEL If you are using one of the iMultiMix 8 USB’s internal effects, this knob controls the effect level. If AUX SEND B is connected to an external device, this knob controls the level for AUX RETURN B.
A Tour of the iMultiMix USB iPod Section The iPod section contains the controls for your iPod. With the iMultiMix you can not only play content from your iPod, but you can also record your mix directly to it. Please note that not all iPod models are compatible for playback and recording from the iMultiMix –...
Power Supply Unit This unit provides 18.5 VAC at 1000 mA, more than enough to keep your iMultiMix 8 USB running smoothly. As with nearly all power supply units, this one tends to get warm when left on for a while.

Digital Effects Processor Onboard your iMultiMix 8 USB™ is a powerful effects unit that has 100 preset programs. We offer a few tips on where to use these, but don’t limit yourself to our suggestions. We recommend that you experiment with these effects to get a good feel for how they can improve your mixes.
Digital Effects Processor CHORUS These create the effect of multiple voices (or instruments) sounding at once from a single input. FLANGE These create a sweeping, swooshing sound effect that you will probably recognize. DELAY These effects are based on a discreet repetition or echo of the input.
Applications Your iMultiMix 8 USB can be used in a wide variety of ways in both live and recording applications. You have several options for bringing sound into and out of the board. And when it’s brought in, you can route it to various parts of the mixer for certain desired effects, or even send it to an external processor or tape deck and back.
Using Additional External Audio Sources The iMultiMix 8 USB gives you 8 audio inputs in all. If you want to bring external audio sources into a recording or live mix, you can do it in several different ways. Using the 2-TRACK IN, you can add a tape deck, ADAT, CD player or other source to the mix.
Applications recorder—or use dedicated Digital Audio Workstation software— to record and play back CD-quality audio within your computer. A 2-meter USB cable is included. If you need to connect the Multimix across a longer distance, we recommend that you purchase a longer USB cable, as using hubs and other extenders with USB audio often causes glitches and other problems.
