Viewing and Adjusting the Input Audio Level

Viewing and Adjusting the Input Audio Level

The audio level of each 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 16). The audio level can be adjusted from the front panel or under RS-232 or Ethernet control.
