CONNECTIONS
LOUDSPEAKERS
To get a realistic soundstage and full
dynamic range from your Nu-Vista 300,
use it with loudspeakers of a reasonable
efficiency and high power handling. We
reccomend power handling of at least
200W. An average rating for a loudspeaker
these days is about 88dB. This should
mean that for an input of 1 watt, measured
at 1 metre distance, the sound pressure out-
put will be 88dB. This is the minimum
efficiency that we recommend you should
use.
CONNECTIONS
All connections should be made with the
power OFF, i.e. before the mains lead is
plugged in and the unit switched on.
PSU to Amplifier Connections
The Nu-Vista 300 is supplied with three
power supply connecting leads.
Two of the leads are identical.
a)
One of these leads connects the
right PSU output to the right PSU input on
the amplifier.
b)
The other one connects the left PSU
output to the left PSU input on the
amplifier.
Push the connectors into the sockets and
twist until they click in to place.
c)
The third lead supplied is to con-
nect the control PSU output to the control
PSU input on the main amplifier. Push the
connectors into the sockets.
The Nu-Vista 300 can be used with a pre-
amplifier or any line level source which
has a volume control. We highly recom-
mend the matching Nu-Vista preamplifier.
How to connect your Nu-Vista 300 for
Normal Stereo use.
Connect the Left and Right outputs from
your pre-amp or other line level source to
the phono inputs on the back panel marked
as Left and Right Audio Inputs. For the
best results we recommend that you use
Musical Fidelity Nu-Vista interconnect
cables for this connection.
Connect your loudspeakers to the loud-
speaker terminals situated on the back
panel marked as Left and Right
Loudspeaker Outputs. We recommend that
you use Musical Fidelity Nu-Vista O.C.C
speaker cables for this connection.
Once these connections are made, plug in
the IEC type mains lead supplied with the
unit.
RECHECK ALL THE CONNECTIONS
BEFORE SWITCHING ON.
DO NOT TOUCH THE SPEAKER TER-
MINALS WHEN THE UNIT IS OPERAT -
ING.
The NU-VISTA 300 is a very powerful
amplifier and is designed to supply high
voltages and high current through the loud-
speaker terminal
