Lectrosonics LE Series - Manual (Page 5)

FRONT PANEL DESCRIPTION
ACTIVE/BYPASS SWITCH - The Active/Bypass switch provides the user a means to bypass both the equalization
and notch filters in the LE8. All other functions and controls are active (consistent, of course, with the position of
the Operate/New Setting switch). When the Active/Bypass switch is in the Bypass mode, the Link Out signal is
brought to logic low.
ACTIVE LOGIC INPUT DISPLAY - The Active Logic Input LEDs indicate the Logic Input whose associated filter
parameters are currently loaded. The Active Logic Input LED will continue to
be on until another Logic Input is active. Note that the LEDs stay on even if
the previously active microphone is no longer in use, until another Logic Input
becomes active. The LEDs will blink if the Active/Bypass switch is switched
into the Bypass mode.
EQUALIZER (TREBLE, MID TREBLE, MID BASS, BASS) - The Equalizer
buttons select which of the equalizer filter functions is currently active. The
LEDs associated with the buttons serve to indicate which function is active
after the button is pressed. Once a filter function has been selected, it may
be adjusted using the Adjust control. Note that these buttons are active only
when the Operate/New Setting switch is in the New Setting position.
NOTCH FILTERS (1, 2, AND 3) - The Notch Filter buttons select which of
the notch filters is currently active. The LEDs associated with the buttons
serve to indicate which filter is active after the button is pressed. Once a
filter function has been selected, it may be adjusted using the Adjust control.
Note that these buttons are active only when the Operate/New Setting switch
is in the New Setting position.
NOTCH FREQUENCY/EQ LEVEL DISPLAY - The Notch Frequency/EQ
Level display indicates the particular setting of the selected filter function.
When one of the equalizer filters is active, the LEDs indicate the amount of
cut or boost of the selected filter function. Adjustment range for the equalizer
filters is +/-10dB in 1dB steps. When one of the three notch filters is
selected, the LEDs indicate the frequency nearest the center of the selected
filter.
OPERATE/NEW SETTING - The Operate/New Setting switch controls the
operational mode of the LE8. In the Operate position, the LE8 scans the
Logic Inputs and Link In. If an active Logic In is detected, and if Link In is at
logic low, then the appropriate filter set is loaded into the programmable
filters. All user controls except the Active/Bypass switch are ignored in the
Operate mode. In the New Setting mode, operation is identical to the
Operate mode with the exception that all user controls are active.
STORE SETTING - The Store Setting button provides a means for saving
the filter parameter of the currently active filter to the non-volatile memory
associated with the currently active Logic Input. Pressing the store setting
button will store the setting of the currently active filter functions only and
cause the currently active filter function LED to blink once to indicate
successful filter value storage. Note that the Store Setting button is only
active when the Operate/New Setting switch is in the New Setting position.
TO RESET MEMORY - To restore the original factory settings, hold down the
NOTCH FILTER 3 and STORE SETTING buttons while turning on the MAIN
POWER SWITCH on the AC1, EC1, or SC1. The EQ and NF LEDs will
blink. Now turn the MAIN POWER SWITCH off, release the buttons, and
turn the MAIN POWER switch back on. Memory is now reset to original
factory settings.
