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.
