Operation
8685 Front Panel
• Headphone Jack allows you to monitor various outputs of the processing
through headphones. Headphone impedance should be 75Ω or higher.
• You can switch the headphone feed to emit the following processor output sig-
nals: LF, RF, C, LS, RS, LFE, LB, RB, STEREO L, STEREO R, L DOWNMIX, R
DOWNMIX, LF/RF, C, LS/RS, LB/RB, STEREO, DOWNMIX. The first 12 signals are
monophonic and are sent to both earpieces. The remaining signals are stereo.
This control is located on the I
NPUT/OUTPUT > OUTPUT 5 screen.
• Headphone Level Control (the small blue control knob to the right of the jack)
adjusts headphone output level.
• The red Enter button allows you to choose pop-up menu items, icons and but-
tons. If you are in the Preset screen, it allows you to put a Factory or User Preset
on-air once you have selected it.
If you edit a Factory Preset, you must save it as a new User Preset to re-
tain your edit permanently. Even if not saved, your edited preset will be
retained automatically even if the 8685 is powered down and will be re-
stored on-air upon power-up. If not saved, your edited preset will appear
in the RECALL list of available presets as the name of its parent present
prefixed by the abbreviation “modif” (for “modified”).
However, if you edit another preset, your old edited preset will be lost—
the 8685 automatically retains only one “modified” preset. Therefore, it
is wise to rename and save any edited preset you wish to keep, using the
8685’s SAVE main menu item. This ensures that your edited preset will
not be overwritten accidentally.
• The green joystick, labeled Locate, is a pointing device that allows you to locate
to settings and controls on each screen. Some main menu items require multiple
screens to show all controls. When multiple screens for a given main menu item
are available, pressing and holding the knob left or right moves you between
screens.
• A yellow Escape button allows you to navigate quickly to underlying screens,
higher-level screens or the Meters screen and displays the pop-up menu.
