with a color-bar test pattern from a test disc or other source on the tv screen, you can
make the following adjustments:
• the color intensity setting on your tv.
• color adjustments using the color bars, which may be (left to right) black, white,
• color adjustments using the color bars, which may be (left to right) black, white,
yellow, cyan (turquoise), green, magenta, red, blue, black.
• the color transition, seen as sharp separation of the bars.
• the performance of the color circuits in your tv (with video signals); bar edges
• the performance of the color circuits in your tv (with video signals); bar edges
should show no vertical crawling dots.
use the gray scale and the black/white fields in the test pattern to adjust the brightness
and contrast.
Brightness Adjustment
1. turn down the color control on your tv until the color bars appear in black and white.
2. Adjust the contrast to the lowest level where you still can see all gray-scale bars
1. turn down the color control on your tv until the color bars appear in black and white.
2. Adjust the contrast to the lowest level where you still can see all gray-scale bars
separately and clearly.
3. Adjust the brightness so that the bars in the gray scale are all visible. the bar farthest
to the left has to be as black as possible rather than gray, but the next gradation must
clearly be distinct from it. the bars in the gray scale should gradually and evenly
change from black to white.
Contrast Adjustment
1. Adjust the contrast on your tv until you see a bright white bar in the lower right corner
1. Adjust the contrast on your tv until you see a bright white bar in the lower right corner
of the screen and a deep, dark, black bar to the left.
2. If the brightness of the white bar no longer increases when the contrast is turned
up or the borders of white letters bloom (overlight) into the black areas (drastically
decreasing the sharpness of the letters), the contrast has been turned up too much.
reduce the contrast until these effects disappear and the video still looks realistic.
3. If you are watching tv with ambient daylight, adjust the contrast so that a normal
video picture looks the same as the surroundings in your room; that way the eye is
relaxed when watching the tv picture. reduce the setting when the surrounding light
is dimmed to improve the sharpness of the picture.
4. the gray scale in the middle line should retain the same distinction between each
bar as before the contrast adjustment. If not, repeat both Step 3 of the brightness
Adjustment and the contrast Adjustment.
Color Adjustment
1. when the brightness and contrast are set optimally, adjust the color control. Set the
1. when the brightness and contrast are set optimally, adjust the color control. Set the
level so that the colors look strong but still natural, not overdone. If the color level is
too high, depending on the tv, some of the bars will seem wider or the color intensity
will not increase when the control is turned up. test the color intensity with a video of
pictures of faces, flowers, fruit and vegetables.
2. refer to a large white bar in your test pattern to tweak the warmth of the picture using
the tint control on your tv.
Sharpness Adjustment
contrary to intuition, the picture will appear sharper and clearer with the sharpness
contrary to intuition, the picture will appear sharper and clearer with the sharpness
backed off from the maximum setting. reduce the Sharpness setting on your television,
and the setting on the Avr, if necessary, to minimize the appearance of any white lines
between the bars in the gray-scale portion of the test screen.

speakers or the manufacturer’s web site for their frequency-range specification. Although

meter purchased at a local electronics store will provide greater accuracy.

without using the ezSet/eq process, the Avr can’t detect how many speakers you’ve
connected to it; nor can it determine their capabilities. consult the technical specifications
for all of your speakers and locate the frequency response, usually given as a range, e.g.,
100hz – 20khz (±3db). write down the lowest frequency that each of your speakers
is capable of playing (100hz in the above example) as the crossover in table A3 in the
Appendix. note: this is not the same as the crossover frequency listed in the speaker’s
specifications.
for the subwoofer, write down the transducer size. the Avr’s bass management
for the subwoofer, write down the transducer size. the Avr’s bass management
determines which speakers will be used to play back the low-frequency (bass) portion
of the source program. Sending the lowest notes to small satellite speakers will result in
bad sound and may even damage the speakers. the highest notes may not be heard at
all through the subwoofer.
with proper bass management, the Avr divides the source signal at a crossover point.
with proper bass management, the Avr divides the source signal at a crossover point.
All information above that crossover point is played through your system’s speakers,
and all information below the crossover point is played through the subwoofer. this way,
each loudspeaker in your system will perform at its best, delivering a more powerful and
enjoyable sound experience.
