4 – Routing & assignment : Routing48 TASCAM DM-3200 User’s ManualTIPNote that linked modules allow you to select indepen-dent sources.Also note that while the same source may be routed tomore than one destination layer (you might want to tryrecording a vocal line with different compression set-tings, for example), a destination layer can only acceptone source (of course!).Batch routing It may be a little troublesome attimes to select eight consecutive inputs and thenroute them to eight separate consecutive destinations.To set up eight input/destinations at one time, movethe cursor down to the batch setup area at the bottomcenter of the screen (3 in Figure 4.2, Routing inputs).The destination is on the right and the source is onthe left.1 Move the cursor to the destination field anduse the dial and ENTER key to select eight des-tinations (not in dynamic trigger layer selec-tion).2 Move the cursor to the input source selectionon the left.3 Use the dial to select a group of eight inputsfrom the input source selected using POD 3(some input sources have only eight inputsanyway and in double-frequency mode somesources may only have four inputs). You canuse POD 3 to select another input source.4 Press ENTER. When you press ENTER, theeight input sources are assigned in order to theeight destinations.Flipping the channels It is possible to “flip”channel inputs between the input and return sources(so that the “input” source becomes the “return” andvice versa) on an individual basis within the MODULEscreens (see “INPUT/RETURN selection” onpage 70), but it is sometimes convenient to be able todo this for batches of eight channels at a time.This is done from this INPUT screen using the BATCHSETUP at the bottom of the screen. Of course this canonly be done for channels 1 through 32, as these arethe only ones for which the input and return sourcesmay be selected.1 Use the dial to select the destination field (theleft field) and confirm with ENTER.2 Move to the on-screen button SOURCE INVERT(inverts the sources) and press ENTER. Apopup appears asking for confirmation. PressENTER again to flip the selected eight chan-nels (a cursor key cancels).Loopback options The loopback options provideeven more flexibility in internal routing, but theyshould be approached with caution.They allow the sixteen busses, aux 1 through 8 or ste-reo buss, or the direct channel outputs of the first 32channels (similar to direct outputs on an analog con-sole) to be used as input sources to channels.The display shows Bx/Dy (x can be from 1 through 16and is repeated twice, while y is from 1 through 32,e.g. B1/D17) or BUSS 1 through BUSS 16 or AUX 1through AUX 8 or STEREO L or STEREO R when a loop-back routing is selected.When a channel has a direct output selected, thedirect output from that channel overrides the corre-spondingly-numbered buss.The direct option allows the selection of only thedirect module outputs (1–32) as sources. Note thatthe selection of DIRECT as a channel destination,using the selection keys, removes the channel fromthe busses.WARNINGAs the name of these loopback options suggests, theyallow flexible internal repatching, which could result ina loop whereby the output of a buss also acts as aninput to the same buss, resulting in a feedback loop.When monitoring, this can result in damage to hearingand monitoring equipment.Before using these options, we suggest that you workout on paper what exactly you are trying to achieve,and it may help if you draw a diagram to help you workout the ultimate sources and destinations of the routingin your system.Digital input selection At the bottom right ofthis screen, the physical connector (XLR or RCA) foreach of the stereo digital inputs can be selected.
