D62 OPERATORS’ MANUAL

REPLAY A, B, C, D:

The four positions A, B, C and D (in yellow) are used for playback from a

digital multitrack recorder to the AES/EBU and SPDIF outputs, 16bit or

High resolution mode will be automatically selected.

Which specific tracks are replayed are detailed at the bottom of the table

on the following page.

If high resolution tracks are replayed with any of the tracks missing

audible distortion will be heard.

RECORDING NOTES

The multitrack tape must be pre-formatted at the required sample rate with

Emphasis Off before recording from the D62.

When recording to a multitrack machine, the SAMPLE RATE should be set

to EXT CLK and the rear panel INPUT SELECT set to TDIF/ADAT as the

multitrack tape machine must supply the master clock.

Note: On the DA88/DA38 the ‘Fs’ LED will flash, it does not affect the

recording.

High resolution recording:

When the required resolution is greater than that of the multitrack

machine, the 1962 splits the 2 digital signals into 3 channels, where the

3rd channel is used to store the remainder bits. For example, when using

a 16bit multitrack machine to record a stereo 24bit signal, tracks 1,2, and

3 (or 5,6 and 7) must be selected. The third channel sounds like white

noise and is used to reconstruct the 24bit signal on playback. With the

availability of 20bit and 24bit machines, there is no need to split signals

below the word length of the machine, so 3 software versions are available

to ensure full compatibility.

16bit version.

When 'WORD LENGTH' is set to 16 bit, signals are recorded to multitrack

without splitting, so all 8 tracks are available.

If 'WORD LENGTH' is set to 18, 20 or 24bit signals are split into 3 tracks

(1+2+3 or 5+6+7).

20bit version.

When 'WORD LENGTH' is set to 16, 18 or 20 bit, signals are recorded to

multitrack without splitting, so all 8 tracks are available.

If 'WORD LENGTH' is set to 24bit, signals are split into 3 tracks (1+2+3 or

5+6+7).

24bit version.

With this version, there is no need to split the signals, so whichever

resolution is selected, signals are recorded directly, leaving all 8 tracks

available for use.

It is important to remember that for any high resolution recording to be

successful, the (tape) operator must enable recording on ALL of the

tracks of the chosen output group (1+2+3 or 5+6+7).
