Viewing and adjusting the TP input audio level

The audio level of each twisted pair 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 (figure 3-50). The audio level can be adjusted from the front panel or under serial port or Ethernet control. The default audio level is 0 dB.
