  • Page 21: Chapter 1: Getting Started

    Getting Started Hooking up the Multimix This diagram will help you get the Multimix 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 22: Setting Levels

    Getting Started For the S/PDIF Digital out, we suggest that you use a coaxial cable that is specifically designed for S/PDIF applications. These cables are better suited for high frequency (digital) signals and are unbalanced, shielded coaxial cables with shielded RCA connectors on each end. Better to get the high quality S/PDIF cables and save yourself some unnecessary grief.

  • Page 23: Chapter Two: A Tour Of The Multimix

    (Multimix-12FXD and Multimix-16FXD only) 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 25: 2-Track

    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 26: Pan Or Bal

    A Tour of the MultiMix 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 27: 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 28: Hdph / Ctrl Rm

    A Tour of the MultiMix 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.

  • Page 29: Led Meters

    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.
