7. Microphone technique, or how to get the
sound you want, requires experimentation.
Moving closer to the microphone increases the
perceived ‘warmth’ and ‘bass’ (Proximity
Effect). Try to get the sound you want by
placing either reflective or absorbent panels at
various angles adjacent to the source.
Changing the acoustic properties of the space
the microphone is in, is our recommended initial
approach for obtaining the best sound quality.
The BROADCASTER ‘ON-AIR’ INDICATOR:
While the BROADCASTERS’ output connection
and On-Air Indicator control is a very simple
operation to perform, we suggest that unless you
are familiar with cable connections and audio
installations in general, that you have an
Audio/Electronics Technician perform this task to
assure optimum performance.
The On-Air Indicator L.E.D. is switched either On
or Off by applying an open or closed circuit
across Pins 4 and 5 of the output connector.
When ‘open circuit’ (no connections across Pins 4
and 5), the L.E.D. is active. If you do not wish to
switch the L.E.D. via a console or separate mute
button, then the L.E.D. will be active continuously
whenever the microphone has P48V (Phantom
Power) applied.
Most professional consoles have switches that
provide both open circuit or short circuit outputs.
These are usually called ‘Channel On” or
‘Channel Mute’ controls and actually mute the
audio signal as well as providing external
contacts. These external contacts are usually
used to mute audio monitors and switch On-Air
lights at the same time as microphones become
active. These contacts can also be used to
activate the BROADCASTERS’ ‘On-Air’ indicator.
Remember, the L.E.D. does not interfere with the
audio circuit, and has no other function than that
of an indicator. The microphone does not mute
itself! The indicator is simply that; an indicator of
the status of what another device is doing.
(Console Muting).
A 5 Pin female connector is supplied, and you
can use a four-core screened (Quad) microphone
cable which is readily available from most
professional audio suppliers, or you can use any
cable which is a two-core screened plus 2 extra
control wires if the L.E.D is to be switched.
