To remove lows, turn theknob counterclockwise past the center. To change the high-frequencycontent, follow the same procedure; turn the TREBLE knob right to addhighs, turn left to diminish them.The BASS and TREBLE knobs on the A-16CS send control data to thehost A-16R rack.Master VolumeThe overall system volume is controlled by the M ASTER volumecontrol. Turn it counterclockwise for a full off setting. As a generalsuggestion, start with the Master volume knob at a low setting, andraise the volume slowly from that point to a comfortable level.Note: Always use caution when adjusting any audio systemcomponent to avoid potential hearing damage.The A-16R volume control is a true Master volume control, even whenthe A-16CS Control Surface is connected. Incoming volume messagesfrom the A-16CS Control Surface are scaled by the A-16R front panelvolume control.The A-16R’s front panel volume control is active at all times,regardless of the position of the R EMOTE /L OCAL switch. The MasterVolume knob provides overall volume adjustments of the main mixlevel without having to switch to L OCAL mode on the front panel of theunit.This feature allows an engineer to set the maximum safe volume levelat the A-16R and know that the user with the A-16CS Control Surfacewill never be able to exceed that amount.Note that switching from remote to local control with the R EMOTE /L OCAL switch may cause an increase in the overall volume, since thisremoves the A-16CS Control Surface from the signal path.
