Choosing CD Attenuation
4
CD players have an output level that is 12 dB or more above that of conventional sources
like tuners and tape decks. For that reason, we believe you may find it beneficial to add
12 dB of attenuation in the CD input path. This is especially true if you have very
efficient loudspeakers, like those made by Klipsch.
If you add 12 dB attenuation in the CD path:
You will have better control over the volume at low listening levels, as the
volume control won’t be crowded towards the counterclockwise end.
You will have to advance the volume control more to produce loud playback
levels, but there’s typically plenty of room in the pot travel for that.
If you don’t add 12 dB attenuation in the CD path:
Depending on your speaker efficiency, you may find your volume control
crowded to the counterclockwise end to produce low listening levels.
You won’t have to advance the volume control as far to produce loud playback.
Adding 12 dB of Attenuation to the CD Input
You’ll find the resistors you need in the “CD Attenuation” envelope. If you want to add
12 dB of attenuation to the CD input, the install the following resistor values as indicated
in this table.
Orange, yellow, gray, brown, brown

Adding no attenuation to the CD Input
If you don’t want to add any additional attenuation, then install the following resistor
values as indicated in this table.

I don’t add the 12 dB attenuation, but my case may be kind of special. I have inefficient speakers, and
tend to play CDs at high levels because I play background tracks behind my saxophone practice.
