Whenthe DA-78HR is turned off, settings will be retainedin memory.2 Tape loading slot and EJECT keyOnly use Hi8 ME or MP tapes as specified in 1.5,“Recommended tapes”. The DA-78HR will automat-ically eject all other tapes.NOTE—I MP OR TAN TDo not use a tape which has been used for recordingvideo. Always use either new tapes or tapes whichhave been used in a DTRS recorder.The EJECT key ejects any loaded cassette. A cassettecan only be ejected when the transport is stopped.3 FORMAT/Fs keyThe FORMAT/Fs key controls the formatting of tapesand allows selection of the sampling frequency usedfor recording (see 5.1, “Formatting a tape” for fulldetails). The current sampling frequency is shown onthe status indicators 6.4 HR MODE keyThis key allows the selection of the recording resolu-tion (16-bit or high-resolution 24-bit). See 5.1, “For-matting a tape” for details.The appropriate indicator 6 will light if the HRmode is selected.5 CLOCK keyThis is used to select the word sync source for theDA-78HR (either internal, WORD or DIGITAL IN, asshown on the indicator 6).6 Status indicatorsThe status indicators show the current status of vari-ous DA-78HR functions. The legends of these indi-cators are abbreviated for reasons of space. Here is alist of their full meanings, together with the pages onwhich the functions are more fully described:7 Tape counterThe tape counter gives the current tape time in hours,minutes, seconds and frames.It is also used to display menus, sub-menus and thevalues of the parameters of the unit, as well as pro-viding information on the current status of the unit.8 PB CONDITION indicatorThere is one more indicator: PB CONDITION, whichlights if there are many errors when reading orrecording the tape. It also flashes when the blockerror rate is being checked (11.1.2, “Checking errorrates”).If this lights frequently, the block error rate can bechecked and the heads cleaned (11.1, “Head andtransport cleaning”).2.2 Tape transport keys andcontrols9 REW keyRewinds the tape at high speed.If this key is pressed during recording, recording willstop and the tape will rewind.A F FWD keyWinds the tape forward at high speed.If this key is pressed during recording, recording willstop and the tape will wind forward.NOTEWhen either REWor F FWDis pressed for the firsttime after powering up, or loading a tape, the unit firstconfigures itself for the reel hub diameter of the tapein use, during which the tape advances at lowspeeds.
