If the [-2 dBFS] (PEAK) indicator lights red, the input signal has reached the maximum allowable level. If excessive input level is indicated, either reduce the output level of the connected source, or reduce the input level via the appropriate rear-panel [PAD] (34 dB) switch or by using INPUT GAIN. NOTE • dBFS stands for "decibels full scale," and indicates the digital audio level. 0 dBFS is the maximum level. 5 [EQ] button This button opens the "INPUT EQ" dialog box, where you can edit the EQ that is provided on each input channel. This is the same as the BLOCK screen's "INPUT EQ" dialog box; refer to page 20 for details. 6 [F.B. SUP] button This turns the feedback suppressor on/off (MONO INPUT channels only). The on/off state of this button is linked with the Feedback Suppressor check box in the MISC screen. For more about the Feedback Suppressor, refer to page 29. IMX644 Manager Owner's Manual 23
