tip: saving input level settings
As a shortcut, you may save the current input level setting for the currently-
selected input by pressing and holding the input level button for a few sec-
onds. This serves as a shortcut to the menu item for the current input.
12 M U T E
Pressing the
mute button will reduce the main output level of the preampli-
fier by a user-modifiable amount, ranging from 0.5 to 60 decibels. Pressing
the mute button a second time without adjusting the volume will return it
to its previous setting.
If you adjust the volume with either the front panel buttons or the remote
control while in the mute mode, the preamplifier will adjust its volume
from the muted volume and disengage the mute function.
The factory default setting of the mute circuit is -20 dB. (See Using the
AVP2 for information on changing the factory default setting.)
13 POWER BUTTON AND INDICATOR
Assuming that the Audio Video Preamplifiers power cord is connected to
AC power, pressing this latching power button connects the AVP2 to the AC
mains and turns on the unit. When power is restored after an interruption,
the AVP2 will enter standby after a few moments delay to allow its circuits
to stabilize.
If AC power is being supplied to the Audio Video Preamplifier, the LED
above the power button is amber. Naturally, when AC power is discon-
nected, the LED is off.
14 MASTER
Normally, any adjustment made with the volume knob will be applied to all
loudspeakers equally, including Center, Rears, and Subwoofer(s), thus raising
or lowering the overall volume without changing the relative balance of the
various speakers. This is the default mode of operation for the volume con-
trol, to which the AVP2 automatically returns after you make other adjust-
ments (after a brief delay).
If you have changed the relative volume by adjusting balance, center, rear,
or subs, and wish to return more quickly to the normal master volume
control, pressing this button will override the usual delay and return you
immediately to master volume control operation.
15 BALANCE
Pressing this button followed by adjusting the volume knob will alter the
relative volume of the Front Left and Front Right speakers. The direction of
the perceived image shift is indicated by the arrowhead indicators in the
main display, as well as by the on screen display. When the balance is cen-
tered (favoring neither side over the other), the display will read
< –– EVEN >.
Turning the knob clockwise in the balance mode will shift the image to the
right; turning the knob counterclockwise will shift the image to the left.
