STEP 1 – Connecting the analogue outputs
Choose one of the following two sections:
Using a preamplifier
•
Set the preamplifier volume control to a low level.
•
Connect either the balanced (XLR connectors) or unbalanced (RCA phono connectors) outputs on
the player’s rear panel to matching line level inputs on your preamplifier (probably labelled CD or
AUX).
•
Turn the player’s rotary control clockwise to set the
Volume
to maximum (
- 0.0dB
on the display).
•
Slowly increase the preamplifier volume until the music is at the right level.
•
If the preamplifier volume setting for a comfortable listening level is too high or too low, you may
need to change the
Output Level
setting.
•
Press the buttons in this sequence:

Setting the
Output Level
to
6V
can cause some preamplifiers to distort. For this reason,
we recommend the
2V
setting if a preamplifier is used.
Using a power amplifier directly
•
Set the player’s
Volume
to around -40.0dB as shown on the display.
•
Connect either the balanced (XLR connectors) or unbalanced (RCA phono connectors) outputs on
the player’s rear panel to matching inputs on your power amplifier. Switch on the power amplifier.
•
Turn the player’s rotary control slowly clockwise until the music is at the right level.
•
If
the
Volume
setting for a comfortable listening level is higher than
–10.0
or lower than
–30.0
, try
changing the
Output Level
setting.

Balanced Outputs
!
The most common fault reported when using our balanced outputs is hiss, unstable levels
and a thin sound on both channels. This is caused by connecting the player’s balanced
output stage to an unbalanced input on an XLR connector with pin 3 left unconnected.
This does not work correctly with a balanced and floating output stage – you must connect
pin 3 to pin 1 (ground) to complete the signal path.
Another possible cause of this fault (probably on one channel only) is a broken cable.
Figure 1 – Output connections for the Vivaldi One
The Vivaldi One has independent balanced and unbalanced output stages, you can connect them to
different amplifiers if you wish.
