Viewing and Adjusting the Input Audio Level (Audio Models)
On models with audio, the level of each analog audio input can be displayed and adjusted
through a range of -18 dB to +24 dB to ensure that there is no noticeable volume difference
among sources (see figure 38). The audio level can be adjusted from the front panel or
under remote control. The default audio level is 0 dB.
