4.3 Connectors
For both safe use and performance reasons, do not modify the standard cables supplied.
4.3.1 Interconnect Cables
Naim interconnect cables that share the same connector on each end are marked with a
band to establish correct orientation. The band denotes the end that connects to the signal
source. Naim Super Lumina interconnect cable will provide the best results.
4.3.2 Signal Outputs
The NVC TT Phono Stage features audio outputs on 5 pin DIN and RCA outputs, and an 8
pin DIN power supply input (NSC 222, NAC 332 or NPX TT), making it easy to connect to a
variety of Naim and other manufacturers' equipment. Always use high quality interconnect
cables to connect the phono stage to the amplifier inputs.
4.3.3 Mains Connection
Connect the NPX TT Power Supply to a mains power socket using either the mains lead
supplied or a Naim Power-Line.
4.4 Powering Up/Down
Once all your input and output connections are made, connect the supplied mains lead to
your NPX TT and then to a mains power source.
Ensure your sources - your turntable, for example - and any associated external power
supplies are switched on before you switch on your NPX TT.
Always use the power switch on the product rather than a mains outlet switch for both
powering and on and off.
A "thump" may be heard from the loudspeakers as power amplifiers are switched on.
This is normal, will not cause any loudspeaker damage and does not point to any fault or
problem. A mild "pop" may also be heard shortly after equipment is switched off.
4.5 Standby Power Settings
The NVC TT Phono Stage powers down into a sleep mode after 20 minutes as its default.
In this sleep mode ('Auto Standby') the system consumes less than 0.5W of power. The
'Instant On' feature sets your system to a mode that leaves the sensitive audio circuitry
permanently powered for the best sound quality.
The standby power setting on the NVC TT phono stage is only applicable when it is
powered by the NPX TT power supply. The standby power setting on the NVC TT phono
stage depends on the power supply used. It needs to be powered by a pre-amplifier which
can control the standby settings.
4.6 Cartridge Selection
The NVC TT Phono Stage features adjustable settings to enable the best performance of
a connected cartridge. It is possible to adjust both gain, capacitive and resistive load for
Moving Coil (MC) cartridges. The adjustment switches do not apply for Moving Magnet
(MM) cartridges as they typically have a much higher output.
The NVC TT is preset to MC mode with cartridge loading values of 100ohms and 1000pF
and the high gain setting. The gain and loading can be adjusted using the rear panel
switches to match your cartridge choice. Check with the cartridge manufacturer for the
recommended values. They can be adjusted for personal preference.
