Mains Power Input on Nu-Vista PRE PSU
Check the Nu-Vista PRE
PSU back panel mains switch is set to “OFF”. Connect the supplied mains lead to
the 16A IEC socket on the back panel. Connect the other end to a mains power socket. Be sure to leave the
mains switch in the “OFF” position.
CONTROL, LH and RH Power from Nu-Vista PRE PSU to Nu-Vista PRE pre-amplifier unit
Connect the 4-pin XLR cable between the CONTROL output on the Nu-Vista PRE PSU and the CONTROL
input on the Nu-Vista PRE pre-amplifier.
Connect both 5-pin XLR cables between the LH POWER & RH POWER outputs on the Nu-Vista PRE PSU
and the LH POWER & RH POWER inputs on the Nu-Vista PRE pre-amplifier. There are powering the pre-
amp stages.
Important notes:
-
Only switch the Nu-Vista PRE PSU on once ALL connections are made.
-
Only connect or disconnect power cables when the ON/OFF switch on the Nu-Vista PRE PSU
is set to OFF!
-
If the LH and RH POWER cables are wrongly or not connected, the Nu-Vista PRE display will
show
“Output DC present” and mute the unit. Turn the Nu-Vista PRE and then the PSU off and
check the cables again.
Trigger Input and Output
Triggering input and outputs are available to allow the amplifier to be turned on automatically by other
equipment or turn on other equipment automatically when the Nu-Vista PPRE is turned on. This is a 2-way
3.5mm jack on the back of the unit labelled “TRIGGER”. It requires 5 to 12V (either polarity) to switch the
amplifier on.
Mounting optional Spike Feet
The Nu-Vista PRE and PRE PSU can optionally be used with spike feet. We recommend to ask a second
person to help you lift the amplifier and PSU units for mounting the feet or felt pads.
If you want to use the standard mounted feet, you can attach the big felt pads to those feet (remove the small
rubber feet first if necessary).
To mount the spike feet, screw the threaded rods into the spike feet so that the allen key side is inside the foot
(this way, when you want to remove the foot from the amplifier again, you can unscrew the foot and then
unscrew the threaded rod from the amplifier with an allen key, should it be too tight to unscrew by hand). Then
screw the feet into the amplifier (remove the small rubber feet first if necessary). Attach the small felt pads to
the bottom of the spike feet cups and place these cups under the spike feet.
