CONNECTIONS AND OPERATION
Issue 2: Feb 2004
BEFORE SWITCHING ON
Plug the accessory IEC mains lead into the
rear panel socket, then the other end into a
wall outlet.
Turn the volume control low on your audio
system, and switch on its power.
OPERATION
Press the
POWER button on the Tri-Vista
21 DAC - the power indicator LED on the
front panel will light confirming that the
unit is now ready for use.
Start the required digital source playing.
The
LOCKED data indicator LED on the
front panel will light to show that the Tri-
Vista 21 DAC has sucessfully locked on to
the incoming data stream, and either the
CO-AXIAL or
OPTICAL LED shows
which input has been selected.
If there is no incoming digital data to
either input, the
CO-AXIAL and
OPTI-
CAL LEDs will flash alternately, and the
LOCKED LED will flash more rapidly.
The appropriate
96kHz or
192kHz light
will indicate which sample rate is in use,
but this can be changed by pressing the
SELECTOR
push-switch at the rear of the
unit as required.
Now adjust the volume control on the
audio system to obtain the preferred sound
level.
All input, output and power connections
should be made with the mains power
switched OFF.
INPUT
CONNECTIONS
The Tri-Vista 21 DAC will convert digital
data from any CD, SACD or
DVD-audio
source to analog audio, but not data from
AC3, Minidisc, or MP3 formats.
However, the digital output socket will
loop any selected digital source for
external processing if required.
Connect the digital output from your CD
or DVD player (or other digital source) to
one of the Tri-Vista 21 DAC’s inputs.
The Tri-Vista 21 DAC has two inputs, one
an optical “Toslink” and the other an
S/PDIF* co-axial RCA socket. Either one
is automatically selected by the presence of
a digital signal, but if both are accidentally
connected at the same time, priority is
given to the first of the two inputs present-
ed.

CONNECTIONS
Using good quality co-axial audio leads,
connect left and right audio outputs from
the analogue output sockets on the back
panel of your Tri-Vista 21 DAC to any line
level input in your amplifier system, for
example the CD or auxiliary sockets.
The co-axial RCA digital output can also
be connected to suitable external digital
equipment if required.
