sockets. Control markers are only a rough guide to
frequency and band width
10.1 NOTCH-Q CONTROL
: Sharp to Broad Band Width
Application
Sets the bandwidth or spread of notch cut for the filter
around the frequency setting of the NOTCH Control
Rotary Pot. Turning ACW to "Sharp" reduces width of cut
towards minimum width while turning CW up to "Broad"
increases width of notch cut towards maximum
A sharp width enables you to seek and remove typical
narrow but problematic feedback peaks
10.2 NOTCH FREQUENCY SELECTOR: 50Hz - 6kHz
Sets the approximate centre frequency from 50 Hz (low
bass) - 6kHz (treble) via a Rotary Pot to which the "Q"
Pot sets a broad or narrow notch cut either side of the
position
10.3 NOTCH FILTER SWITCHES
i) 2 Way Slider Switch determines whether the Notch
Filter is In or Out. This enables you to instantly determine
whether you like the application set "ON" or "OFF"
without altering settings. The LED indicator illuminates
BLUE when filter is applied
ii) 2 Way Slider Switch applies Notch Filter to Ch. 1 or
Ch. 2 alternately
10.4 NOTCH FILTER IN USE
This is a versatile, supplementary tone control which can
be used quite subtly at the "Sharp" end or severely at the
"Broad"/Wide end. It is the most precise and effective
