Starting
Once all connections are made, switch on the
Nu-Vista PRE PSU
unit, using the
POWER
switch on the back
panel. The
Standby
LEDs on both the
Nu-Vista PRE and PSU
will light up. The
Nu-Vista PRE
amplifier unit
may now be switched fully on using the
POWER/STANDBY
button on the front of the amplifier or the remote
control (see page 10). The display will now light up and the
POWER LEDs
on both units
will light up. The LEDs
illuminating the Nuvistor valves will light up
RED
. This means the outputs are muted, and will remain in this
state for about 12 seconds, so no sound will be heard from the speakers. Once the delay is up, these LEDs
go
ORANGE
, indicating the unit is ready for use, and any source material selected and playing will be heard.
For the first 15 mins or so, the Nu-Vista valves are still warming up, and their LEDs stay
ORANGE
. After
approx. 20 mins the valves will have reached full thermal equilibrium and are at their best performance, which
is indicated by their LEDs turning
BLUE
.
Switching Inputs
Switch through the inputs by rotating the
SOURCE
selector. Switching inputs can also be achieved by pressing
the corresponding button on the remote control (see page 10).
Volume Control
The volume should be adjusted for normal listening levels. This is done by turning the volume up/down knob
on the front panel. Adjusting the volume can also be achieved using the remote handset, using the volume
up/down buttons (see page 10).
+ 6 dB Gain
With the
+ 6 dB
button on the front panel or remote control (see page 10), you can 6dB of extra input
gain, which is stored for each channel individually. You can use this to bring single ended RCA inputs up to
the level of the XLR inputs or match different sources (turntable source vs. streaming source).
Mute (Remote Control only)
The output may be muted by use of the
MUTE
button on the remote control. Press once, and the LEDs will
light
RED
indicating muted state. No sound will be heard from the speakers. To return to listening, simply press
the
MUTE
button again.
Display Controls
Access the
display controls
by pressing the
DISPLAY
button once and then:
Change the
theme
between black/white, VU meters on/off by pressing the
DISPLAY
button.
Change the
brightness
by pressing the
POWER
(brightness down) and
+ 6 dB
(brightness up) buttons.
Display controls
will automatically exit after not pressing any buttons for a few seconds.
Pressing and holding
the
DISPLAY
button for a few seconds will
turn off
the Nuvistor LEDs. This only works
after the valves have fully warmed up and their LEDs changed from orange to
BLUE.
If the valve
LEDs are turned on
, you can recognize this by a thin blue line that is shown at the top of the
display screen.
If the valve
LEDs are turned off
, this thin blue line is
not shown
.
The display can also be controlled by pressing the corresponding buttons on the remote control (see page 10).
POWER OFF CAUTION:
The correct power off procedure should be followed in order to prevent unnecessary power surges on the
mains line and to protect the Nu-Vistas. The
Nu-Vista PRE
amplifier itself should be switched OFF first by the
POWER/STANDBY
button on its own front panel or the remote control (see page 10). Only then turn off the
Nu-Vista PRE PSU
on its back panel. For day-to-day operation both the
Nu-Vista PRE and PRE PSU
can
simply be switched to ON or into STANDBY using the
POWER/STANDBY
button on the Nu-Vista PRE front
panel.
