microphones will also operate on a lower voltage.
9.3 PHANTOM POWER CONSTRAINTS: EDB-2 VAP cannot be
powered via phantom power from a mixer, due to insufficient milli-
amps provided. EDB-2 VAP is a multi function device and not a
simple, minimal D.I box and the quality of components used have
NOT been compromised to run at low quality, at a low power
consumption
Valves cannot be run via phantom power (or batteries)
Applying phantom power from a mixer to EDB-2 VAP will not
damage the unit
10.0 NOTCH FILTER CH.1 & CH.2 – ANTI-FEEDBACK / BOOM.
Width at grey knob. Cut at blue knob - Located on top
Sometimes known as a “sweep" the notch filter utilises two rotary
pot controls, an On/Off switch and a channel selector switch. They
apply either to line out and D.I outputs. Control markers are only an
approximate guide to frequency and band width
10.1 NOTCH-Q CONTROLS. “Sharp” to “Wide” bandwidth
application. Sets the bandwidth or spread of notch cut for filter
around the frequency setting of the Notch control rotary pot. Turning
ACW to narrow or “Sharp” reduces width of cut towards minimum
width while turning CW up to “Wide” increases width of notch cut
towards maximum
A “Sharp” width enables you to seek and remove typical narrow but
problematic feedback peaks
