Echo Effects Functions and Operations page 10 6 PAN CONTROL The Channel Pan positions the output of the channel in the stereo field of the Master Mix Its constant power design ensures there are no level discrepancies whether a signal is hard panned center stage or somewhere in between 7 PEAK LED INDICATOR The Peak LED illuminates when a channel is going into overload It detects the peak level after the EQ and will light at 3 dB before clipping to warn that the signal is approaching overload You do not want the Peak LED to light except very intermittently during a take or a mix If it does light persistently reduce input gain with the TRIM control 3 8 CHANNEL GAIN CONTROL The channel gain controls determine the output signal level to the Master Mix bus There is no PFL function on the MXE 612 In order to audition any single channel for proper gain you can turn off the gain control of all the other channels fully counterclockwise and set both the auditioned channel and Master Mix control 29 to unity gain 0 dB The LED Output Meter 21 should read around 0 dp CONTROLS AND CONNECTIONS 2 STEREO INPUT SECTION LINE L R 13A L MONO LINE INPUT On stereo input channels 3 6 the 1 4 line inputs are designed for 1 3A stereo or mono line level signals such as those from keyboards drum machines CD players tape decks or samplers However these inputs can also be used as standard mono line inputs by conn
