NuWave Phono Converter
Phase and stereo/mono select choices apply ONLY to the phono stage and not the analog inputs.
The choices of phase and stereo/mono will be presented on both the pure analog outputs and the
digital outputs of the NPC.
The INPUT screen offers two menu choices: Analog/Phono and Play/Mute. The top SELECT
button chooses between the two available inputs, ANALOG and PHONO.
The Analog Input accepts any analog output up to 3v
rms
input level (a direct analog output from
a CD player, for example, is typically 2v
rms
) at up to 80kHz. The bottom SELECT Button chooses
between PLAY and MUTE. PLAY and MUTE functions are active only on the Analog Outputs and
do not affect the digital data stream output of the NPC.
The A/D Mode screen offers two menu choices: PCM/DSD and USB Disabled/Enabled. The
top SELECT button chooses between PCM and DSD and the bottom SELECT button chooses
whether USB is disabled or enabled.
Selecting PCM (Pulse Code Modulation which is commonly referred to as Digital Audio and is
the standard for CD’s) or DSD (Direct Stream Digital which is sometimes referred to as SACD) will
determine the digital output stream of the NPC. The three available connections for the digital
datastreams are I
2
S (through a rear panel HDMI connector), COAX (through a rear panel RCA
connector) and USB (through a rear panel “B” type USB connector). Whichever format is chosen
on the front panel display, PCM or DSD, will always be available at the I
2
S and COAX outputs.
USB will only be active when it is enabled.
USB is a type B output, meaning it is a slave device and suitable to connect to a computer only.
You may not connect the USB output of the NPC to a USB input on a DAC. Enabling the USB
output from the NPC front panel should only be done if you are actually connecting to a computer.
Once enabled, the next screen on the NPC display, that selects the sample rate of the chosen
audio format, is disabled. To change the sample rate of the NPC when in the USB Enabled mode
you must use your connected computer as the User Interface. Please refer to the section specific
to USB setup and recording in this manual for further details.
If you have selected PCM as the digital output audio format (and USB is disabled), the next screen
available by pressing the UP on MODE is the PCM SR screen. The choices on this screen are
FREQ and BITS and these control the SR (Sample Rate) and bit depth.
The upper select button toggles through the available frequencies:
• 44.1kHz
• 48kHz
• 88.2kHz
• 96kHz
• 176.4kHz
• 192kHz
