  • Page 10 "Effects," many other names also describe these features. They are sometimes called "Busses, Foldback, Echo or Monitor" sends. Although any of these names are perfectly appropriate, the MX2488 uses "Cue" and "Effects" for simplicity and ease of set-up. Usually the "Cue" sends will be used for headphone (Cues), and the "Effects"...

(i.e. All channel CUE #1 channel controls are summed together at the CUE #1 Master Output).
  • Page 13 allows individual channels to send more or less signal depending upon their "Cue" or "Effects" settings (in relation to other channels). These "Relative" signals are then electronically summed (maintaining their relative volume differences) at the "Send Master" controls. The Send Master controls then adjust the overall signal level to drive either a signal processing device or amplifier.
  • Page 14 It operated on 6 volts and provides an excellent source of light. It may be positioned to see back panel connections or front panel controls in dimly lit areas. The mini-light is offered by Carvin & may be purchased for $25.00 dollars. (Model #G-12)
  • Page 15 The "Slate" switch feeds a talkback signal to all of the Main Outputs of the MX2488. This feature is usually used to Cue tapes or for audio labeling of each recording.
  • Page 16 The control room "select" switches directly below the Solo Level control will allow you to access the signals appearing at the (2) Track Outputs, (2) Track Playback (Inputs), Cue Outputs, and Effects Outputs connections at the rear panel of the console. By depressing any of these switches, or groups of switches, their signals will be fed to the control room outputs (after adjustment by the Control Room Faders) for subsequent amplification to the control room monitors.

  • Page 20 This is an input with far greater sensitivity than the "Line Input". Line Inputs typically accomodate input voltages of 200 millivolts to 2 volts, whereas Mic Inputs will accomodate input signals of 10 to 100 millivolts. This input is sometimes called a "High gain" input, because It is designed to amplify low level signals.
  • Page 21 channel direct outputs may be used to directly route signals to appropriate channels on the multi-track tape recorder. Simply leave the channel assignment switches in the "up" or unassigned position. This will interrupt the signal flow to the eight main outputs while still offering the signal at the channel direct outputs.
  • Page 22 These connections are pre-amp connections intended to drive a power amplifier - subsequently powering your control room monitor speakers. As with all inputs and outputs of the MX2488 you are advised to use good quality shielded cable. This will provide the best possible quality and lowest noise.
