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 AFB Mode
This initializes the AFB mode. There are parameters that
initialize the entire AFB mode, as well as parameters that
initialize individual functions.
[FILTER RESERVE: Number of Reserved Filters]
(AUTO: 0 to 18, DYNAMIC: 0 to 18)
MENU > AFB mode > RESERVE >
The number of filters that can be used simultaneously is a
total of 18 bands for each channel. This parameter sets
how the 18 bands are allocated to the three functions (A —
Auto, D ~ Dynamic, and M — Manual). The number of filter
bands that can be set with each function is within the
value set here.
[LINK] (ON or OFF)
MENU > AFB 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.
«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.
eWhen Link Is Switched from ON to OFF
This sets which channel ~ left or right — is affected by panel
operations for the Auto or Dynamic functions.
L CH:
Settings affect only the left channel.
RCH:
L+RCH:
Settings affect both the left and right channels.
Settings affect only the right channel.

¢ 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 Channel to Edit
This selects the channel affected by panel operations. The
current setting is shown on the Analyzer/Filter screen.
L CH:
Panel operations affect only the left channel.
RCH:
Panel operations affect only the right channel.
L+R CH:
Panel operations affect both the left and right chan-
nels.
To change the channel setting, move the cursor to the
channel display ("L CH," "R CH," or "L+R CH"), and press
[ENTER]. This switches you to the setting screen.
Filter Operation During a Quick Edit Session
The channel ("L" or "R") appears to the left of the filter num-
ber.
Auto Function
This perform initialization when using the Auto function.
[STEP] (0.5 to 40.0 dB)
MENU > AFB mode > AUTO/DYNA >
This adjusts the amount of change in the level that takes
place at one time for the filter suppressing feedback (howl-
ing). If the amount of change is small, some time is
required to suppress feedback, but changes in sound quali-
ty can be reduced. A large amount of change allows feed-
back to be suppressed quickly, but sound quality may
change considerably.
[RESPONSE] (SLOW1 to FAST10)
MENU > AFB mode » AUTO/DYNA >
This adjusts the time until a signal above the threshold is
recognized as feedback (howling). Settings close to "Fast"
result in signals above the threshold being recognized as
feedback in a more immediate manner. Conversely, set-
tings close to "SLOW" result in a slower response. If you
should obtain undesirable results, such as when there is
frequent noise at the mike, it can be set to "SLOW."
[THRESHOLD] (-60.0 to +20.0 dB)
MENU > AFB mode >» AUTO/DYNA >
This adjusts the level at which the Auto function recog-
nizes the input signal as feedback (howling).
If the input level rises above the threshold, the input signal
is considered to be feedback and the frequency response is
corrected.
