    Introduction How to Use This Manual This manual is divided into the following sections describing the various functions and applications for the Multimix consoles. While it's a good idea to read through the entire manual once carefully, those having general knowledge about mixing should use the table of contents to look up specific functions.
  • Page 11: A Few Words For Beginners

    A Few Words for Beginners We realize that some of you who have purchased the Multimix USB are fairly new to the art of mixing, and we’ve written this manual with that in mind. We designed the Multimix to be both powerful and easy enough to use that even a beginner can quickly pick up the basics.

  • Page 13: Chapter 1: Getting Started

    Getting Started Hooking up the Multimix USB This diagram will help you get the Multimix USB hooked up and ready to go. The equipment you use depends on personal preference and on whether you’re performing live or recording. For example, you’ll see below that the MAIN MIX OUT can be routed to a recording device for recording, or to a PA system for live performance.
  • Page 14: Setting Levels

    Getting Started Use a USB cable to connect the USB port to a computer. Do not use a USB hub, as hubs can introduce timing glitches in USB communication. For the S/PDIF Digital out, we suggest that you use a coaxial cable that is specifically designed for S/PDIF applications.
  • Page 15: Chapter Two: A Tour Of The Multimix

    A Tour of the MultiMix USB In this chapter, you’ll learn all about the MulitMix’s components (except for the digital effects processor, which is explained in the next chapter). Please refer to the diagrams as you read each section to see which components we’re talking about. Patchbay At the rear portion of the top of the Multimix, you’ll find the patchbay.

    Digital Output Jack The digital output jack is used to send the 44.1 kHz stereo audio signal to an Alesis Masterlink or any other recording device such as a DAT recorder or a PC with an S/PDIF enabled sound card installed.
  • Page 17: 2-Track

    A Tour of the MultiMix USB 2-TRACK The 2-TRACK IN and OUT jacks are standard RCA jacks. You’ll use the OUTs for mixing to a tape deck or other recorder. With the INs you can bring in a signal, which can be monitored and even added to the main mix via the 2TK TO MIX switch in the master section of the mixer.
  • Page 18: Pan Or Bal

    A Tour of the MultiMix USB troubleshooting. PFL stands for “pre-fade listen.” In other words this switch lets you hear the signal before it is affected by the fader. This switch is post-EQ. PAN or BAL This control—labeled PAN on the mono channels and BAL on the stereo channels—lets you assign the channel to a particular spot within the stereo spectrum.
  • Page 19: Master Section

    Master Section The Master Section is the heart of the mixer, where the channel inputs and aux returns all are mixed together and routed in various ways. Main Mix Fader The signals from all channels and aux sends—excluding those that are muted—are sent to the main mix.
  • Page 20: Hdph / Ctrl Rm

    A Tour of the MultiMix USB HDPH / CTRL RM The HDPH / CTRL RM knob controls the level of the signal being sent to the CTRL RM OUT and the PHONES output. The level of this signal is represented by the LED meters. The switches to the right of the HDPH / CTRL RM knob determine the source of the control room mix as explained below.
  • Page 21: Led Meters

    A Tour of the MultiMix USB LED Meters These are the two rows of yellow, green and red lights you see in the master section of the mixer. They are very versatile, allowing you to view the signal level of the main mix, individual channels (both pre- and post-fader) and aux returns depending on which signal you have routed to the control room mix.
