MANUAL

SETUP INPUTS DVD1 ANGL IN LVL MANUAL

-18 to +12dB	parameter indicates the amount of automatic input level
	adjustment.

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.
