[MARGIN] (0.0 to +12.0 dB)
MENU > AFB mode » AUTO/DYNA >
When the Auto function is searching for a feedback point
(in other words, during operation of the Auto function), the
output level can increase by only the level set here.
When the Auto function is exited, the level returns to its
original value, providing a margin against feedback.
Dynamic Function
Like the Auto function, the Dynamic function is also pro-
vided with independent parameters. To guard against sud-
den feedback, however, its settings are normally different
from the Auto function. The step is larger, the response is
set closer to "FAST," and the threshold is set higher to pre-
vent operation from being triggered by an input signal (an
ordinary signal other than feedback).
[STEP] (0.5 to 40.0 dB)
MENU > AFB mode > AUTO/DYNA >
[RESPONSE] (SLOW1 to FAST 10)
MENU > AFB mode > AUTO/DYNA >
[THRESHOLD] (—60.0 to +20.0 dB)
MENU > AFB mode >» AUTO/DYNA >
Diffuse Function
This makes the settings for the Diffuse function. Because
the frequency at which feedback occurs is normally deter-
mined by the distance between the mike and the sound
reinforcement device, feedback can be eliminated by mov-
ing the microphone. The Diffuse function creates this effect
electrically.
[CYCLE] (0.1 to 20.0 sec)
MENU > AFB mode > DIFFUSE >
This adjusts the cycle.
[DISTANCE] (0.01 to 14.0 m)
MENU > AFB mode > DIFFUSE >
This adjusts the distance.
Mute Function
[MUTE LEVEL] (— ~ to 0.0 dB)
MENU > AFB mode > MUTE >
This sets the amount by which output will be attenuated
when the Mute function is on.
Editing in the PEQ Mode
HPF and LPF Settings
The same procedure is used in each mode to make the set-
tings for the HPF and LPF. See "HPF and LPF Settings
(Common for All Modes)" (p. 20) for a description of this
procedure.
Initializing the PEQ Mode
This initializes the PEQ mode.
[LINK] (ON or OFF)
MENU > PEQ mode > LINK >
This makes the setting for linking the channels,
ON:
The two channels operate in the same way.
OFF:
The channels operate independently. Because all set-
tings are independent, separate settings are made for
each channel.
e When Link Is Switched from OFF to ON
This sets which channel -- left or right -- will serve as the
basis for the settings that are applied commonly to both
channels when Link is set to ON.
L CH:
The settings for the left channel become the com-
mon settings for both channels.
RCH:
The settings for the right channel become the com-
mon settings for both channels.
e Operation When Link Is Set to OFF
Because the channels act independently when Link is set
to OFF, the following settings are possible.
Selecting the Displayed/Manipulated Channel
This selects the channel whose settings are shown and can
be manipulated in the Analyzer/Filter screen.
L CH:
Settings for the left channel are displayed/become
manipulable.
RCH:
Settings for the right channel are displayed/become
manipulable.
To change the channel setting, move the cursor to the
channel and press [ENTER]. This switches you to the set-
ting screen for the channel.
