You can also create a different, default input level setting for each analog
source defined in the menu system. If you can generate a 1 kHz, 0 dB ref-
erence signal in the source component (for example, a cassette tape record-
ing of a 1 kHz test tone, with the recording meters showing 0 dB), use this
signal to calibrate the input. With the volume of the AVP turned down, play
the 0 dB test tone, and adjust the input level until the indicator light first
turns on. Reduce the input level setting a few decibels to allow for peaks
above 0 dB, and then press either the
enter button on the remote or the
mute button on the front panel (which serves the same purpose when in
the menu system) to enter this default input level setting for the currently
selected input. (You may repeat this procedure for each analog source.)
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 1 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 AVP
for information on changing the factory default setting.)
13 POWER BUTTON AND INDICATOR
Assuming that the Audio Video Preamplifier’s power cord is connected to
AC power, pressing this latching power button connects the AVP to the AC
mains and turns on the unit. When power is restored after an interruption,
the AVP 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 AVP 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 in
“centered” (favoring neither side over the other), the display will read
< –– EVEN – – >.
