2 - Basic operational concepts : Utilities Utilities There are four UTILITY screens, accessed with the UTILITY key. The first of these (PARAM COPY) provides a method of copying values between channel parameters. This is explained in "UTILITY copying" on page 30. The second (EXT. SW) determines the function of the external footswitch. SWITCH utility When a footswitch is connected to the rear of the unit, it can be set up using this screen in the following way: Figure 2.43: UTILITY external switch settings Talkback The footswitch can be set to act as a hands-free talkback switch, with the destination being set from the following options: TO STUDIO & TO SLATE, TO STUDIO, and TO SLATE. In these cases, the footswitch acts in "smart mode" (see "Smart keys" on page 19). Machine Control Especially in cases where the artist is also the recording engineer, the following GPI settings The DM-4800 allows you to send 8 output signals from the GPI port ('D' sub 9-pin connector) on the rear panel, and control external devices from the DM-4800. The DM-4800 allows you to assign different trigger settings for GPI signal output to each of the GPI ports. The third (SYSTEM) allows CF card management and date setting. These have already been described in "Formatting a new card" on page 32 and "Setting the date and time" on page 35 and are not described again here. The last allows the setup of the GPI control protocol from the DM-4800. hands-free transport operations can be very useful: Punch In/Out, Direct Locate [n], Play/Stop. See "Remote operation" on page 105 for full details of how these functions operate. In these cases, the footswitch operates in the same way as the front panel keys. Other functions The following functions duplicate commonly-used keys. SHIFT duplicates the use of the SHIFT key (to the left of the unit). Automation KEEP performs a keep operation (see the separate Automation Manual for details). Increment Direct Library Recall and Decrement Direct Library Recall allow direct stepping up or down through the current bank of the current library (see also "Recalling library entries" on page 39). Tap Tempo for Effects allows the footswitch to be used for tapping in the tempo used for a synchronized Effects (useful if both hands are busy playing an instrument!). Mute On/Off for Mute Group [n] provides easy hands-free mute grouping for a specified group, and the EQ On/Off for Current CH allows easy A/B comparisons of EQ settings versus flat response. Polarity This is not a function assignment, but allows the switch's polarity to be reversed (the DM4800 expects a push-to-make momentary switch, but by flipping the polarity to INVERT, a push-to-break switch can be used instead). You can choose the trigger source to be one of the following: a fader, MUTE key control, transport control, machine control key status and its operation, or a timecode value.
