SETTING LEVELS
The CS-3X, Jr. comes from the factory set up for unity gain levels. This means that
whatever levels are going in are also the same levels going out. This is probably
adequate for most situations. However, there are trimpots provided for adjusting
the levels of each individual channel. In addition, there is a volume adjustment
knob (marked CENTER FILL) on the front panel for setting the rear wall (CS) speak-
ers’ volume relative to the Left and Right Surround volume. Typically, the CS
channel volume is set about 3dB higher than the Left and Right Surround chan-
nels. You may want to experiment with the CENTER FILL control to get the best
effect in your particular listening room.
Also, there is built-in pink noise which can be used to help balance the levels
between the surround channels if any adjustment is needed. To activate the pink
noise, push down the DIP switch marked ON. Then to send the noise to a particu-
lar channel, push down the DIP switch corresponding to the desired channel. Be
sure to push all the Pink Noise DIP switches back up when you are finished with
the pink noise.
There are six OUTPUT LEVEL trimpots which are used to adjust the output levels
if needed to balance the levels between the various surround channels. In most
cases, these can be left at the factory settings. If you need to adjust these, use the
supplied alignment tool or a small jeweler’s type screwdriver. These trimpots are
muti-turn types. If you turn them all the way to one end, they will click slightly as
you continue to turn them. You cannot damage them by turning too far.
This picture of the back of the CS-3X, Jr. shows the connection points, controls
and switches which are used in setting up the product for proper operation. The
SP MONO DIP switch is for setting the SP1 and SP2 outputs for mono operation.
It is used for future formats only.
