Introduction
We at would like to thank you and congratulate
you on investing in the Broadcaster.
Like its name suggests, this microphone was
specifically designed for ‘ON-AIR’ applications where
wide frequency response and low distortion are
demanded.
Winner of the Radio World/US National Association
of Broadcasters (NAB) ‘What’s Cool’ award, the
Broadcaster has become an industry standard when
studio sound quality is required for on-air applications.
Utilising an Australian designed and manufactured
1” externally biased condenser transducer, the
Broadcaster features a switchable high-pass filter to
remove low frequency rumble.
A unique ‘ON-AIR’ LED indicator can be switched on
or off by shorting contacts on the five pin audio
connector. This feature allows console operators to warn
the ‘Talent’ that the mic is live. More information on
integrating this feature is available in this user manual.
Please take the time to visit www.rodemic.com and
register your microphone for a full ten year warranty.
While there you can view studio tips and techniques, as
well as browse the comprehensive range of accessories
for microphones.

• The Broadcaster is a phantom powered
microphone. To operate correctly it requires a 48V
phantom supply from the mixing console or other
source.
• It is recommended that you use a high-quality
microphone lead, and keep it as short as practical
for your stage set up. This will ensure the highest
quality sound reproduction.
• The Broadcaster is an ‘end address’ microphone,
so should be addressed with the microphone
mounted lengthways, talking directly in to the
head.
• Please ensure all cable connections are secure
before applying power to the microphone, and
allow a few moments for the microphone to
stabilise after the power is turned on.
• 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 around the microphone is our
recommended initial approach for obtaining the
best sound quality.
Setting the High Pass Filter
• The High-Pass Filter setting can be used to
reduce the microphone’s sensitivity to low
frequency sounds, and is useful when you wish
to avoid additional noise and vibration from
outside traffic, air conditioning and machinery,
foot tapping etc.

• While the broadcaster’s 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 LED 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 LED is active. If you do not wish to
switch the LED via a console or separate mute
button, then the LED 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 broadcaster’s ‘On-Air’ indicator.
• Remember, the LED 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.

• 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 two wire screened
plus two extra control wires if the LED is to be
switched.
