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

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.
