7 – Making settings on the DTRS units

This section covers the operations which relate to the DTRS units, other than those specifically related to timecode.

7.1 Track operations

The following series of operations relate to indi- vidual tracks of the DTRS units connected to the RC-898.

7.1.1 Track delay

When recording or playing back, tracks on a DTRS unit may be delayed by up to 7200 sam- ples, or advanced relative to other tracks up to a value of 200 samples.

This is possible due to the design of the recording and monitoring heads in the DTRS mechanism.

1)From menu group 0, move the cursor to Delay and press SELECT:

T r a c k D e l a y T i m e

0 1

0 0 0 m s e c

 

 

2)Use either the UP key or the numeric keypad to change the track number by individual track.

NOTE

The track number here may be set from 01 to 48. Tracks refer only to DTRS units, not to any other equipment which may be using the REC FUNCTION switches of tracks 41 through 46.

3)When track 1 is shown, you can press the DOWN key to select the eight tracks of the first DTRS unit. Continue pressing the DOWN key to select the tracks in groups of eight for the subsequent DTRS units (i.e. 9-16, 17-24, etc.):

T r a c k D e l a y T i m e

1 - 8

0 0 0 m s e c

 

 

Any changes to the delay time made when a group fo eight tracks is shown will affect the delay time of all tracks on the unit. This allows you to set the

delay times for different DTRS units in the chain easily (to slip times, etc.).

When track 48 is shown on the display, pressing the UP key will select tracks 41-48. Subsequent presses of the UP key will select the other DTRS units in order, working towards the head of the chain.

4)Move the cursor to the numerical value field and use the UP and DOWN keys or the numeric keypad to enter a value.

The +/– key of the numeric keypad allows you to enter negative values here, as shown by the period after the last digit in the LOCATE TIME/VALUE display.

5)If you prefer to work in sample values, rather than milliseconds, move the cursor to the msec field and change it to sample with the DOWN key.

The delay value is now converted to samples at the current sampling frequency, and is up to 4 digits long.

7.1.2 Track copying

3898 This operation allows the assignment of inputs (either digital or analog) on a track-by-track basis. This facility is not available on DA-88 units. This means that a patchbay is not required to reroute input signals

As well as external inputs, tracks which have already been recorded can be used as recording sources. This feature therefore allows tracks to be copied within a unit.

It does not allow routing or copying of tracks between machines, nor does it allow the combina- tion (“ping-pong” of tracks). For these operations, an external patching or mixing system is required. For further details of this feature, consult section

8.11 of the DA-98 manual, or 4-7 of the DA-38 manual.

1)From menu group 0, move the cursor to Trk Copy and press SELECT:
