the other switches (3-10) in the down position. For a moving coil cartridge, the typical load would
be 100 Ohms. Move switches 9 and 10 to the up position keeping all the other switches (8-1) in
the down position. You can also see some other groupings on the back panel. For example, 60
Ohms can be achieved by placing switches 7,8,9,10 in the up position while all others are down.
600 Ohms can be achieved with switches 3,4,5,6 in the up position while all others down.
If you are only using the NPC for phono, you can skip this next bit and go directly to connecting its
outputs up. If you are also - or only - connecting a flat analog source to the NPC, such as a tape
deck, tuner, iPod, VCR analog outputs, etc., then this next part is for you.
If you are planning on using the NPC for analog sources other than a turntable, you will connect
the source to the left and right inputs labeled Line In. Line In is a single ended RCA input that
can accept the output from just about any analog source such as a tuner or tape deck. The input
impedance is a fairly easy load of 47k Ohm which should accommodate a tube, solid state or
transformer coupled output with ease. Again, make sure these inputs are connected to the correct
channels for proper left and right reproduction. Maximum input voltage is 3v
rms
and the bandwidth
extends to 80kHz.
It is fine to have both the Phono Inputs as well as the analog inputs connected at the same time.
Selection of the two inputs is chosen from the front panel display.
There are two analog outputs on the NPC: balanced XLR analog output and unbalanced, RCA
analog output. You may connect either or both of these outputs to any preamplifier or analog
mixing console you wish. They may be used separately or at the same time if needed. Only the
phono input will come through the analog outputs.
There are 4 digital connectors on the rear panel of the NPC. From left to right as you face the rear
of the unit those connectors are labeled: Firmware, S/PDIF, I
2
S, USB.
The firmware connector is used only for firmware updates SHOULD there be any released from us.
To use this input you will insert a USB memory stick containing the firmware update, power cycle
the unit and it will take care of the rest. With the NPC rear panel power switch in the off position,
insert the USB firmware memory upgrade if you are ever instructed to do so (normally you will not
need to do this). Once inserted, turn the rear panel power switch to the ON position and refer to
the front panel display. Do not remove power until the front panel blue logo light stops flashing
or the unit reboots. The new firmware will be installed. Once installed, turn the rear panel power
switch to the OFF position, remove the USB memory stick, and return power to the unit.
S/PDIF is a digital output that can be used to feed a DAC (Digital to Analog Converter), digital
mixing console or computer sound card. This output uses the S/PDIF (Sony Phillips Digital
Interface) standard and will send either PCM and DSD to any compatible receiver. PCM can be
sent from 44.1kHz/16 bit through 192kHz/24 bit and all standard variations between these two
extremes. DSD is sent using the DoP protocol (DSD over PCM) and produces single or double
DSD rate. The DoP protocol maintains the original DSD data without corruption to the original
source. To do this, it breaks up the DSD stream into smaller individual packets that resemble
PCM. Your DSD capable DAC will recombine these packets back together to give you perfect
