Wilson Audio WATCH Center Series 3 - Manual (Page 33)

Section 5.3—Integrating the WATCH System
Note: Many processors offer a setup guide that steps you through the integration of each
of the speakers, specifically, setting speaker distances, delays, and phase rotation. These
adjustments are made via internal electrical adjustments. We have found that actual
geometric changes, that is, moving the speaker location and rotation, offer improved
results when integrating speakers. We recommend that you follow the steps outlined
below, evaluate your system performance, and then make adjustments in the processor.
Ultimately, you will, of course, need to make level adjustments via the processor.
Integrating the WATCH Center
The next step in the setup process is to fine tune the location and rotation of the
Center channel. Do as follows:
• Place the Center channel centered between the main speakers and even
with the front inner edge. Set the spikes as indicated in Section 4.
• Follow the processor instructions on level adjustment. Adjust the level on
the Center channel so it matches in level with the left and right channels.
Do not be surprised if the Center channel requires 5-7 dB lower adjustment
than the left and right channel.
• Make sure that only the front Left, Right and Center channels are connect-
ed.
• Determine the Center is connected with correct polarity. Using a pink noise
generator, play pink noise through the Center channel together with al-
ternating Left and Right channels. If the polarity is correct on the Center
channel, you will hear the pink noise centered between the Center chan-
nel and either the Left or Right speakers. If the polarity is incorrect, you
will hear two point sources that are unfocused and located at each speaker
playing.
• With the Center channel spiked, put on a multi-channel audio track or mov-
ie scene with which you are familiar.
• Play the selection and listen for the integration with the main speakers. As
the audio moves across the three front speakers, listen for a smooth tran-
sition from one speaker to the next. You should not hear any voids in the
sound stage.
• Make 1/2” changes in front to back location until you find the Center chan-
nel location that offers the best integration.
Image Height
Check the image height. Does the dialogue of a movie have the correct height? Is it
too low or too high?
If needed, adjust the amount of rotation until the image height is correct. On a stand
or floor mounted Center channel, raising the front spikes will raise the image height; lower-
ing the front spikes will lower the image height. Where possible, we recommend that you
add or remove a spacer to get the correct image height. This will allow the PDC to be reset
using the tables in Section 10.
Center Rotation
Our testing has shown that a
stand-mounted Center channel, at lis-
tening distances greater than 2-3 me-
ters, requires the front of the Center
channel to be raised about 1”. This is
because the effects of comb-filtering
are more noticeable the further you
are away from the Center channel.
This comb-filtering reveals itself as a
