OVERVIEW OF CHASSIS
Also on the front panel, there are six sets of controls related to inputs, such as
pans, faders, and trims.
Fader (1-6)
Pan (1-6)PFL (Left: 1-6, Right: 7-12)
Trim (1-6)
PFL status / Activity LED (1-6)
HPF (1-6)
Feature Description
PFL Switch By default, this switch has dual-functionality. It activates
Pre-Fade Listen (PFL) and displays Input Settings screen for
input 1-6 (slide left) and 7-12 (slide right). Slide again to
deactivate. The functionality of this switch may be altered
via the Main menu’s Inputs > Input Mode.
Does not affect Master Output signal. For momentary ac-
tion, hold the switch for one second or longer. The input LED
ashes yellow when an input’s PFL is active.
iBecause the CL-6 accessory provides separate PFL switches
for inputs 7-12, when the CL-6 is attached to the 664, the
dual-functionality of the six PFL switches on the 664
changes. Slide left activates PFL and slide right displays
Input Settings for inputs 1-6 only.
Fader (1-6) Adjusts fader level for inputs 1-6.
HPF (1-6) Adjusts corner frequency (-3 dB) of high-pass lter for in-
puts 1-6. Full counter-clockwise position (detented) deacti-
vates HPF. Range is 80-240 Hz, 12 dB/oct to 6 dB/oct.
Trim (1-6) Adjusts trim level for inputs 1-6.
Pan (1-6) Adjusts pan between L and R tracks.
PFL status / Activity LED (1-6) Indicates PFL status and input signal activity.

The LCD and User Interface
Meter Views
The LCD display is the primary source
of information when operating the 664.
All settings are congured via the LCD
display. All signal level meters can be
displayed on the LCD display.
This chapter describes meter views,
including the Main screen which is
displayed when no other screens
are active, the Main menu, and LCD
Daylight mode.
Other screens are described where
applicable throughout the guide.
The 664 displays important metering information at a glance on its LCD. All
meter views provide various combinations of input, track, and return meters. By
default, the rst of three meter views is shown. This view is known as the Main
screen.

Using Meter Views
Although the rst meter view is known as the Main screen, there are other
screens, which may appear on the LCD, such as the Main menu or the Input
Settings screen.
Regardless of what screen is visible, returning to the Main screen and its meter
view is easy.
To return to the main screen at any time:
XPress the METERS button.
You can also easily switch to any of three different meter views.
To toggle between the three meter views:
XPress the METERS button. Each press of the button switches the display to
the next view.
Customizing Meter Views
While the 664 provides three meter views by default, all three may be custom-
ized to display the information you deem most important. The second and third
meter views may also be turned off so that only one meter view is shown as the
Main screen at all times.
To customize the meter views:
1. Press MENU.
2. Turn and press the Headphone encoder to select SYSTEM > Meter Views.
3. Select the meter view you would like to change.
4. Select the display option for that meter view.

ments, including some where lighting is an issue that requires adjustments to
the mixer. With some System settings, you can modify the brightness levels of
the LCD, the brightness levels of the LEDs, and even enable or disable the LCD
Daylight mode.
To set the LCD brightness level:
