8 TASCAM DM-24 2.0 release notesDM-24 version 2.0—Release notes—I/O setup changesIn high sampling frequency mode, only aux sends 1through 4 (AUX1-4) can be selected here.Stereo mix output via TDIF This allows aTDIF connection (TDIF-3) to output the stereo mix.This can be useful when working with a DAW fittedwith a TDIF interface.Additionally, this stereo mix can also be output fromthe ADAT and SLOT 1 and SLOT 2 outputs.Support of TDIF optional slot cardThe TDIF optional slot card is now supported for usewith the DM-24. However, this does not mean that32 channels of TDIF digital input are simultaneouslyavailable for mixing.Instead, it means that you now have the ability tochoose between different sets of TDIF inputs. Forexample, with a DTRS recorder and an MX-2424both connected, it is now possible to select either ofthese as the TDIF input source, using the DM-24 ineffect as a digital patch bay.The extra TDIF output channels can also be used ifyou already have 24 channels of TDIF input that youare mixing in 5.1 format, and you need surroundmonitoring fed by the extra channels.Note however, that in the above example, there isnow a “Y”-splitter cable available (CU/PWSPLIT)which can be used to perform a similar function,splitting the TDIF signal into individual INPUT andOUTPUT. In this example, the INPUT comes fromthe MX-2424 and the OUTPUT is assigned to theDA-78HR.NOTEWhen a DTRS unit is connected to the DM-24 in thisway, it may sometimes happen that the DM-24’s displayis illuminated, even with the power turned off, becauseof power being fed through the connection from theDTRS units. If any difficulty is experienced when power-ing up a system configured in this way, we recommendthat the DM-24 is powered up first.Also note that the DTRS remote terminal on the slotcard is not operational. Use the DM-24’s built-in remoteterminal for control of all DTRS units connected to theDM-24.New input optionsPreviously, channels 25 through 32 were input-only,but from this version, they can be used either as inputor as return channels.However, you should note that this does not provide32-channel digital track mixing (although only 24returns can be assigned, you can now decide wherethey go).For example, channels 1 through 16 can be used asinput channels whose direct outs are used for track-ing, and channels 17 through 32 can be used as tapereturns.Also note that sources within a block do not neces-sarily have to be assigned to channels in order (it ispossible to “cross over” a pair of input sources, forexample). A source may also be assigned to morethan one channel.In addition, if a block has been assigned as a returnblock, sources from this block may also be usedwithin a channel block. For example, if TDIF 1 andTDIF 2 have both been selected as return blocks,channels 1 through 8 may now contain returns fromboth TDIF 1 and TDIF 2 (previously a group of eightchannels could only accept sources from one block ata time).
