ASSIGNING HDMI, AUDIO & VIDEO INPUT CONNECTORS
(continued)
MANUAL
-18 to +12dB
Provides manual adjustment of the 2-channel (and 5.1-channel
when the MAIN ADVANCED
ANALOG BYPASS parameter is set to
OFF) analog audio input levels. Lower levels cause more noise,
while higher levels pose a risk of overload distortion. When manual
adjustments are made, the SDP-40HD automatically sets the ANLG
IN LVL menu AUTO parameter to OFF, deactivating automatic input
level adjustment. Manual input level adjustments are retained when
the AUTO parameter is ON.
Note:
When the AUTO parameter is ON, the SDP-40HD will not make
adjustments that exceed the ANLG IN LVL menu MANUAL parameter
setting.
AUTO GAIN
Indicates the current amount of input level adjustment for the
selected 2-channel (and 5.1-channel when the MAIN ADVANCED
ANALOG BYPASS parameter is set to OFF) analog audio input
connector. This parameter cannot be directly adjusted. When the
ANLG IN LVL menu AUTO parameter is ON, the AUTO GAIN
parameter indicates the amount of automatic input level
adjustment.
When the AUTO parameter is OFF, the AUTO GAIN parameter
indicates the amount of input level adjustment as set by the
MANUAL parameter.
When the AUTO parameter is ON, the AUTO GAIN parameter
continues to indicate the amount of manual input level adjustment
until automatic adjustments have been made.
LEVEL METERS
Indicate fluctuating input levels in the front left (L) and front right (R)
channels for the selected input. Meters are also present for center
(C), surround left (SL), surround right (SR), and sub (LFE) when the
input is set up for 5.1-analog. Like the STATUS menu level meters,
