DIGITAL DATA

Three digital data output formats are supported by the D62 digital interface.

AES/EBU:  via an XLR connector designed to be used with standard balanced

microphone cable (20 metres maximum), wired pin 1 screen, pin 2 and 3
balanced data, and the XLR shell connected to the chassis. Having many
short cables joined together is not advisable as each connector can cause
undesirable signal reflections. The AES/EBU output is enabled when the
Output Select button is in its Out position. The status LED illuminates to
confirm this mode has been selected.

The output socket fully conforms to the EMC standards; if the unit is to be
used where it may be exposed to high levels of disturbance, such as found
close to a TV or radio transmitter, it is suggested that the screen of the
data cable be connected to the chassis connection on the XLR type
connector rather than to pin 1. If ground loop problems are encountered,
never disconnect the mains ground, but instead, try disconnecting the
signal screen on one end of each cable connecting the outputs

S/PDIF: 

via a high quality RCA type phono jack where the data conforms to the
Sony™  Phillips™  Digital InterFace format. Because this connector only
provides an unbalanced termination, the recommended maximum length
for this cable is 3 metres, even with very high quality cable. This socket is
enabled when the Output Select button is set to its

 IN

 position; the status

LED illuminates to confirm selection of this mode.

TDIF:

(Where the D62-T is fitted). This is permanently enabled and presents the
digital data in the standard paired formats. If connection is to a Tascam™
DA88 or DA38, we strongly recommend using the Tascam accessory
Dubbing cable PW-88D which is 1metre in length. We have also
successfully used the 5 metres cable PW-88DL, but external interference
might make digital data or timing signals unreliable.

ADAT:

(Where the D62-A is fitted). This is permanently enabled and presents the
digital data to the standard Alesis™ format, where the stereo signal is
available on all eight tracks for the operator to choose which tracks to
record. If connection is to a Alesis™ ADAT it is suggested that
professionally terminated optical cables are used.

For additional information, refer to the documentation accompanying the
TDIF or ADAT compatible recording or storage device to which this socket
is to be connected.
