[5] RECORD MODE switch

Use this switch to choose between HR(24BIT) and STANDARD. The HR(24BIT) setting records with 24 bits of resolution. The STANDARD setting will record at 16 bits of resolution.

Operating Tip

It is not possible to record a tape partly in HR(24BIT) mode and partly in STANDARD mode (an error message will appear (see 6.5.1, "Warning messages"). If a tape has been recorded in one mode, and it is required to re-record it in another mode, the tape must be rewound to the start, and the new record- ing mode selected using this switch. The RECORD key must be pressed and held, and the PAUSE key pressed. Press and hold the RECORD key once more, and press the PAUSE key. The recording can now take place in the selected mode.

Note that it is not possible to enter input mon- itor mode (see RECORD KEY [17]) if this RECORD MODE switch is set to one record- ing mode and the tape currently loaded in the tape deck is has previously been recorded in another. This helps to avoid the two modes being mixed on one tape.

NOTES

When recording with the switch set to the HR(24BIT) position, the tape moves at twice the normal speed. A tape which is labeled as a 90-minute tape will therefore provide 45 minutes of recording time. The tape time that is displayed in the HR(24BIT) mode is either the ABS subcode, or actual elapsed time, as set in 3.11, "HR time display".

If a tape has been recorded in HR(24BIT) mode, it cannot be replayed on a DAT tape deck that does not support this mode.

When recording digitally from a CD or other material which contains fewer than 24 bits of resolution and this switch is set to HR(24BIT), the lower “extra” bits will be unused.

No setting is necessary to select the bit resolution for playback— the tape deck recognizes the recording mode in which the tape was recorded and adjusts accordingly.

2 - Parts of the tape deck

When the tape deck is in record ready mode, as men- tioned above, turning the DATA dial [20] allows the selection of a program number other than 01, meaning that this recording will start at the selected number, and subsequent programs will be written with numbers automatically incremented from this selected value.

NOTE

Valid program numbers are from 01 to 99. If the above procedure is used to select a pro- gam number at the high end of the range, and the automatic increment procedure takes the number above 99, the number will “wrap” to

00.The number 00 can cause problems when searching and locating, and this should be remembered when setting program numbers.

[6]Fs switch

Use this switch to select the sampling frequency (44.1 or 48 kHz) when making analog recordings. When making digital recordings, the sampling fre- quency is automatically detected.

When playing back tapes that have already been recorded, this switch has no effect. The sampling fre- quency of a recorded tape is fixed, and cannot be changed.

[7] INPUT selector switch

The left (UNBAL) and center (BAL) positions of this switch allow the selection between the unbal- anced RCA jacks or the balanced XLR jacks respectively.

The right (DIGITAL) position allows the selection of the digital input jacks.

[8] DIGITAL INPUT selector switch

When the INPUT switch [7] is set to the DIGITAL position, this switch is used to choose between the RCA COAXIAL and the XLR AES/EBU digital audio input sources.

NOTE

Despite the name of the switch setting and the connectors (AES/EBU), the XLR connec- tors are capable of receiving SPDIF format input, and the RCA COAXIAL connectors are capable of receiving AES/EBU format. The tape deck will automatically detect the input format and adjust itself accordingly.
