Section 7 – Monitoring modes

7.1.3 Shuttle monitoring

In addition to these modes, there is one further

control,[20], that affects monitoring, but only in one special case – shuttle mode. Usu- ally, when shuttling the tape, you will want to monitor off-tape. However, if a track is armed, you may want to listen to the source input signal, rather than the off-tape recording.

NOTE

ALL INPUT overrides any shuttle monitoring selec- tions described below. Any shuttle monitoring while ALL INPUT is on will always be source monitoring.

The SHTL MON key has no effect when AUTO MON is off. While shuttling, you can use tracks’

switches (regardless of arming

status) to change between source and off-tape monitoring.

When the AUTO MON and SHTL MON are both on (the indicators will light), the output from all armed tracks will be the source input. This cannot be changed.

NOTE

You can always (regardless of any other status except ALL INPUT) use the INPUT MONITOR switch of unarmed tracks to switch between source and tape monitoring.

If AUTO MON is on, but SHTL MON is off, all armed tracks will monitor off-tape in shuttle mode. This cannot be changed.

NOTES

You can also disable off-tape shuttle monitoring with the Shuttle Mute function (see 8.6.2, “Shuttle muting”) .

Shuttle monitoring is attenuated by 12 dB compared with other monitoring modes. This helps to avoid dam- age to tweeters, etc. when shuttling fast.

7.2 Confidence mode

When actually recording in a studio, it is usual to monitor the input signals, rather than the tape. This allows accurate synchronization between stu- dio events and the actions of the control room staff. If a “glitch” is later discovered in the record- ing, or it is discovered that a signal has been

wrongly routed, resulting in an unwanted record- ing being produced, it is a relatively simple matter to re-record the take.

In a live recording situation, this luxury is not pos- sible. One can hardly ask an orchestra giving a concert to repeat a movement of a symphony for re-recording purposes!

For this reason, the DA-98 includes a confidence mode which permits off-tape monitoring on a track-by-track basis while recording is in progress.

Confidence mode provides monitoringoff-tape while recording for all tracks, except those tracks

whoseswitch is active. The monitoring of these tracks will be the input source, not tape.

The actual mechanics of how this is accomplished internally are quite complex, but the result is that off-tape signals are delayed by about 240 millisec- onds relative to the input signal. This means that it is not recommended that you perform punch-ins, etc. in the confidence mode.

In the confidence mode, overdubbing will be out of sync with previously recorded tracks, as well as with the input source.

We suggest you use confidence mode only when laying down long takes of basic tracks which will not need punching for correction (e.g. laying down tracks from a video worktape, or classical live recordings). You may also choose to use con- fidence mode when you are dubbing from another audio multitrack tape to the DA-98, to ensure the quality of the transfer.

Another use for the confidence mode is when you are recording using dither (see 8.13, “Dither”). You may want to check the effects of dither on the re-quantized recording as the tracks are being laid down.
