CD-2 Operation Notes
The precision machined and polished
turntable axis is designed to center the
magnetic puck for stable rotation, mini-
mizing a potential source of low frequen-
cy jitter. This axis is polished to prevent
scratching of the CD surface because of
contact with the axis when placing or
removing a CD from the turntable.
You can store the magnetic puck either
on the top surface of the CD-2 top cover
or on the turntable axis when not play-
ing a CD.
You could use a blank CD-rom as a
cover over the CD mechanism when not
using the CD-2.
Because of the comprehensive de-jitter
circuitry in the CD-2 we have found that
the CD-2 is not sensitive to ambient light.
The low level jitter of the audio output
data stream is primarily dependent on
the Ultra-Clock jitter specification.
There will be low level pops on the ana-
log outputs when disconnecting or re-
connecting the external power supply.
The CD-2 incorporates a hard mute cir-
cuit to minimize these pops but there is
some residual level. To avoid any pops
mute the preamplifier or power down
the amplifier that the CD-2 is connected
to whenever attaching or disconnecting
the power supply for the CD-2.
Note that mechanical noises from the
CD-2 linear tracking mechanism are nor-
mal when changing tracks and that there
is a very low level motor noise while
playing the CD. The CD rotating speed
also will change as the CD plays to the
outside tracks. The CD rotation slows on
the higher numbered tracks.
