15 – High sampling frequency—Channels, etc.TASCAM DM-24 Reference Manual 113DUAL-LINE is a “parallel” method, in which a pair ofAES/EBU cables send two channels of high sam-pling frequency audio data.HIGH-SPEED uses one AES/EBU cable to send twochannels of audio data at twice the standard data rate.In this screen, the output format of the four AES/EBU input streams available to the DM-24 can beselected to be either high-speed or dual-line, depend-ing on the capabilities of the other equipment con-nected to the DM-24.This choice also applies to devices connected to theDIGITAL IN and DIGITAL OUT ports of the DM-24,as shown here.The high sampling frequency format of DIGITAL INand OUT 1 and 2 must be altered together (they can-not be set independently) and the MODE choice (at thetop of the screen, highlighted here) is either NORMAL,DUAL-LINE or HIGH-SPEED.NOTEThese settings can also be made in normal sampling fre-quency mode, but the frequency conversion must be setto in for this to apply.Channels, etc.When high sampling frequency has been selected,the number of channels available is halved, from 32to 16.The first sixteen physical faders 1 through 16 areused for this purpose. The fader layer 17-32 has nomeaning in the high sampling-frequency mode.Twelve channels are available for mic/line input, anda further four for channel input.The number of aux sends is also reduced, from 6 to 4.However, the number of busses is unchanged at 8.Also note that the number of AES/EBU channelsavailable on any installed slot cards is now halved.The number of onboard compressors and dynamicsprocessors, etc. is also reduced.However, the functionality of the components thatmake up the modules (EQ, etc.) is not impaired orreduced.
