The same keyboard is used to recall any Memory number to either Playback where the intensity levels can be substituted for the existing levels, or added, or subtracted. The head-up display shows which channels are above zero intensity. The content of either Playback, or the total combined output, can be displayed. The intensity level of any channel is shown on the meter whenever that channel number is selected. There are also auxiliary facilities for direct fader control of ten groups of control channels.
Yellow pins provide a pile-on mode of operation for presentation lighting etc.
Red pins give inhibitor mastering, for example of all the auditorium spotlights, and the means to withdraw any channel from a series of recorded cues. Two different forms of crossfader are available. Either provides a dipless crossfade, while allowing a contoured crossfade whenever is required. The unique joystick version is dipless when operated from side to side, but the contour is variable by movement in any arc above the horizontal, for maximum common levels, or below the horizontal for minimum common levels. Alternatively, the crossfader can consist of two faders side by side, one fader controlling only those channels increasing in intensity, and the other those decreasing in intensity.
