SDP-3 Digital Surround Processor/ControllerSystemConfiguration15Input ConfigurationThe SDP-3 has eight inputs, each of which can be associated with anyof the eight video and eight digital audio inputs. Selecting Input Configu-ration from the Setup menu displays a sub-menu which lists these inputsand allows you to select them individually for adjustment. Each input hasan identical parameter sub-menu. V-DISC is shown below as anexample.SPEAKER CONFIGOUTPUT LEVELSLISTENER POSITIONLOCK SETTINGSSETUP MENUINPUT CONFIGInput Gain (Analog Inputs Only)For optimal performance when using analog inputs, the unit must bedriven to its full input level without clipping. Despite industry attempts atstandardization, different analog sources have a wide range of outputlevels. To compensate for this, each of the eight SDP-3 analog inputscan be assigned a different input gain, assuring optimum performanceregardless of the source. For use with a calibration tone, the Dolbyreference point is indicated by an enlarged tick mark on the Input Levelmeters.The SDP-3 GAIN function can be set to AUTOMATIC to monitor theanalog input level and automatically optimizes the input gain. If thesignal level is too high, input gain is automatically decreased to a pointwhich does not cause clipping. When the signal level remains low(>12dB below clipping for 2.5 minutes), the input gain is increased in1dB steps to maximize dynamic range.When MANUAL is selected, the display shows the last auto levelsetting. (If the auto level feature has not been used, the display showsthe last manually entered level.) The auto level setting indicates theoptimum input level value as determined by the unit. The ▲ and ▼buttons increase or decrease the input gain in 1dB increments for theselected input over a range of -18dB to +12 dB. The setting is displayedin dB along with horizontal bargraph meters on the on-screen display toindicate incoming signal level.Note that if a level is set manually, then AUTOMATIC is engaged, thelevel will not go above the last value entered manually.INPUT CONFIG MENUVCRDVDTVAUXCDTUNERTAPEV-DISCThe GAIN control is only availablefor analog inputs.
