SCR(een) Saver:
The AVS500 automatically activates a “bouncing ball”
screen saver after a few minutes of inactivity. This will
prevent burning an image on to the phosphors of a
conventional picture tube or CRT-based projection TV.
Plasma screens may also be damaged by prolonged
exposure to a constant image.
LCD, DILA, or DLP based products do not normally
require the screen saver.
Although we do not recommend it, you may turn the
“bouncing ball” screen saver off. If you decide to
defeat the Screen Saver, do not leave the player on for
extended periods on any paused or still scene. This
includes the AVS500’s logo screen.
SPEAKER SETUP PAGE
Define the type and layout of your speakers, and bal-
ance their levels.
Test Tone:
Use this after you have defined the speaker layout
using the menu selections below. When you select
ON, a short burst of pink noise will be sent to each
channel in turn. When the system is balanced, each
speaker will play at the same apparent level when
heard at the primary listening position. After selecting
ON, let the tone cycle through all of the channels at
least once. If any of the channels appear louder or
softer than the main left and right channels, they
should be adjusted to play at the same volume. The
buttons on the number keypad correspond to the
speakers in corresponding positions on the picture in
the menu.
1 – Left Front
2 – Center 3 – Right Front
4 – Subwoofer
7 – Left Surround
9 – Right Surround
Press the button corresponding to the speaker requir-
ing adjustment. The Tone will stay on this speaker, use
the volume
+/–
buttons to adjust the volume level. The
Tone will stay on this channel for 5-seconds after you
have completed adjustment. Select the next channel to
adjust and repeat the process. Continue until all of the
channels play at the same apparent volume level.
Hint: The adjustment may be made by ear: however, use
of an inexpensive sound level meter such as Radio Shack
#330-2050 may make the adjustment easier.
Center:
Select ON if you have a center channel
speaker (default).
Rear:
Select ON if you have rear channel surround
speakers (default).
Sub Woofer:
Set ON if you have a separate sub-
woofer, or powered speaker system that does not have
it’s own bass management/crossover circuitry. Set OFF
if your powered subwoofer or powered speaker system
provides it’s own bass management (default). The
BassCube 851 and BassCube 821 both provide their
own bass management.
