Cartridge incorrectly wired.

cartridge selection.
Cartridge incorrectly wired.
Input connector plugs not
fully pushed in.

fully pushed in
Cable fault.
Unsuitable Cable
(e .g . cable grounds
not connected).
High gain of Nu-
Vista Vinyl 2,
amplifying normal
circuit transients.
Cartridge and/or tone
arm not aligned properly.

needle. Dirt on record.
Line outputs of Nu-Vista
Vinyl 2 plugged into
PHONO amplifier inputs
of following amplifier.
Remedy
Plug in securely into unit's IEC socket.
Check audio input and output lead connections.
Check cartridge wiring.
Use MM setting for MM
cartridges. Use MC setting for
MC cartridges.
Check turntable tracking weight and cartridge
setup. Check plugs are inserted fully and
securely.
Check turntable earthing lead is connected to earthing post.
Disconnect earthing lead from earthing post.
Investigate for earth loops elsewhere in system.
Insert plug securely and check cable is connected at both ends.
N .B . some esoteric cables have internal wiring intentionally
disconnected/ modified. For best results on all inputs AND
outputs, please use good quality screened coax; fully
connected signal-to signal, screen-to-screen.
Not a fault. It is recommended that the volume level on
amplifier is turned down if switching the Nu-Vista Vinyl 2 on or
off; or pressing option switches whilst connected.
Carefully follow turntable instructions to correctly re-align tone
arm and cartridge.
Replace needle or cartridge.
Clean dust and dirt from
