Section 7.2 - Unit-related functions

7.2.12 Confidence mode

98The DA-98 allows off-tape monitoring while recording (confidence mode). This can be switched on or off on a per-machie basis.

However, since there is a slight delay between the input signal and its replay in confidence mode, you should not use confidence mode in the follow- ing circumstances:

•When making punch recordings, as you will not be able to hear the exact timings for punch operations.

•When operating a mixed chain of DA-98s and other units. The delay introduced by confi- dence mode on the DA-98 will make these tracks appear to be out of time with the other tracks.

However, confidence mode can be very useful when making test recordings so that you can instantly hear the effects of different dither set- tings (see 7.2.11, “Dither”), or to monitor possible clipping at high recording levels on a test take, allowing you to “back off” the level a little before making a final recording.

1)From menu group 9, move the cursor to ConfdMod and press SELECT:

C o n f i d e n c e M o d e

M a c h i n e 1

o f f

2)Use the UP and DOWN keys to select between the three states: off, ready and on.

Confidence mode is selected using this three-state switch to prevent accidental switching of the unit into confidence mode, which might otherwise cause confusion when performing monitoring operations.

7.2.13 Reference levels

98 The reference level for analog I/O on the DA-

98 can be set to one of three standard values: European, TASCAM and SMPTE. These levels correspond to:

Standard

2) Use the UP and DOWN keys to select between

-16,-18 and -20 dB.

The appropriate reference level indicator(s) next to the meters on the DA-98 unit will light. See sec- tion 8-7 of the DA-98 manual for further details of reference levels.

7.2.14 Meter modes

98 On the DA-98, the peak hold time and the decay ballistics of the meters can be changed.

1) From menu group 2, move the cursor to

MeterMode and press SELECT:

F a s t

 

 

 

2)Move the cursor to the Peak Hold setting, and choose between the following values: 0 through 9 seconds (in 1-second increments) and continue.

The continue setting sets an infinite peak hold time. The peak levels can be reset by setting the time to 0 seconds.

3)Move the cursor to the Release setting, and choose between the following release times:

Fast, Medium and Slow.

The meter functions are described in section 8.8 of the DA-98 manual.

7.2.15 Sine oscillator

98 The DA-98 incorporates a sine oscillator for line-up purposes at either 440Hz or 1kHz. The level of the oscillator is a full bit +16dBu (but can- not be compared to transient signals, on account of the constant nature of a sine-wave oscillator).
