1962 OPERATORS’ MANUAL
5
outputs of the 1962 to the patchbay. If such measures are necessary, balanced operation
is recommended. Various signal cable earthing options may have to be tried to achieve the
most hum-free connection.
STEREO MIX IN/OUT
The Stereo Mix In/Out sockets are stereo TSR jack connections which simplify connection
of other 1962 units, stereo sends from a mixer, or similar line level device(s). The wiring
convention is: ring, right channel, tip, left channel and sleeve ground. These signals are
unbalanced and operate at a nominal +4dBu level.
Stereo Mix In/Out connections are provided so that other high quality analogue sources may
be combined with the output of the 1962 prior to digitisation. Furthermore, in systems
comprising of multiple 1962s, only one need be fitted with a D62 digital converter. This
option saves on cost and also provides a convenient method of mixing, especially where no
digital mixing facilities are available.
DIGITAL CONNECTIONS
(Only where D62-T or D62-A module is fitted)
DIGITAL CLOCK SYNCHRONISATION
When clocking the D62 from an external, master clock source, there are two possible
methods of termination. When using the TEAC® TDIF-1 Digital Interface protocol, which
uses a 25 pin D-sub connector system, or ADAT
® optical system, the Input Select button
should be in the Out position. Alternatively, external synchronisation may be achieved via
the 75Ω BNC connector, in which case the Input Select button should be set to its IN
position. The operation of the D62-A version is identical, except that the multitrack interface
is ADAT. When the unit is suitably connected, observe the Input Select LED status to
confirm the following clock conditions:
