General Operation
Turning the unit on/off
Turn on the Power Switch (POWER) on the left side, the display will show PRIMALUNA Premium CD,
and the unit will perform a self-check. When the display shows READING, the self-check has been
completed and the unit is ready to read the disc.
Playback
• Press the Stop/Open Button on the front panel or the remote control to open the disc tray.
• Place the compact disc in the disc tray label-side up.
• Press the Stop/Open Button on the front panel or the remote control to close the tray.
• Once the display indicates the number of tracks on the disc and the total time of the disc, press
the Play/Pause Button on the front panel or the remote control to start playback. If the disc tray is
open when you press the Play/Pause Button, it will close automatically and start playing.
Normally, the disc will start playing with track 1. However, you can select a different track by pressing
the Skip Buttons.
Track Search
• During playback or in STOP mode, you can select a track to play by pressing the Skip Buttons.
• Press the Forward Skip Button to advance to the beginning of the next track. If the current track is
the last one, pressing this button will return the player to track 1.
• Press the Backward Skip Button to reverse to the beginning of the previous track. If the current
track is the first one, press this button to reverse to the beginning of the last track.
Pause
During playback, press the Play/Pause Button on the front panel or the remote control to temporarily
pause playback.
Press the Play/Pause Button again to resume playback.
When the player is in PAUSE mode, the disc motor is still spinning. Since leaving the player in this
condition can shorten the lifetime of the motor, do not leave the player in PAUSE mode for a long
period of time.
In PAUSE mode, after advancing or reversing to the next track, the unit will still be paused.
USB Input
For use of the M2Tech USB input, please go to page 14.

The SuperTubeClock
This is where the magic happens... the SuperTubeClock replaces the solid state oscillator normally
found in a CD player’s digital clocking device with a mini triode vacuum tube.
When you reclock a cd-drive, any noise that is generated here appears unfiltered and unattenuated at
the input of the decoder chip in the cd-player and injects jitter, which from then on is an
undistinguishable part of the digital audio stream. No amount of cleaning will ever be able to remove
this noise once it reaches this point; it has become part of the audio signal. There is a distinctive loss
of dynamics, tonal purity, intertransient silence, and sense of timing. We call this “noise modulation.”
When the clock is used to clock the DAC chip, a similar situation occurs as described above: the noise
appears at the location where the digital audio stream is converted to successive steps in a staircase
wave, which represents the analog audio signal. Each step has to be EXACTLY 1/441000th,
1/96000th, 1/176400th, or 1/192000th (depending on whether there’s oversampling or upsampling, CD
or DVD). The injected noise introduces a deviation in time which is the exact replica of that noise. This
means that the audio signal at the outputs of the DAC chip has the noise riding on it, again as an
inherent part of the signal. No amount of filtering will remove the noise once it reaches this step. Again
we experience that smear and detail masking, with that distinctive loss of dynamics, tonal purity,
intertransient silence, and sense of timing.
By replacing the standard solid state oscillator with a tube, we have significantly lowered the amount of
jitter and noise, resulting in superior detail retreival. This in turn yields superior detail and dynamics
from top to bottom, and improved overall musicality.
