CONNECTIONS AND OPERATION

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.

OUTPUT 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.

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-AXIALor OPTICAL LED shows which input has been selected.

If there is no incoming digital data to either input, the CO-AXIALand 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.
