A mixing desk allows you to connect microphones and speakers and adjust volume and settings to ensure clear sound broadcast through amplification. A telephone interface and compressor allow calls to be taken and audio levels balanced. Headphones help monitor broadcasts by blocking background noise while microphones allow hosts to speak to audiences. Digital cart walls and play out systems preload content like jingles and ads to play during broadcasts, and soundproofing minimizes interference from outside sounds.

1. Mixing Desk
A mixing desk is a console that allows you to connect the microphone and
speakers to the mixer and adjust the volume, various other settings of these
equipment to ensure they are providing good clear sound. The mixer is able to
control analogue and digital signals, which can be broadcasted and amplified
through sound reinforcement.
Telephone interface/Compressor/Speakers
A telephone interface allows you to take and receive calls from people calling
in the show. This software is similar to talkback system as you are able to see
who is calling into the station and are able to direct them to the specific show
they require to be on. The compressor allows you to have more control of the
microphone, allowing you to have the microphone channel open all the time,
as you don’t need to fade in, making the audio levels balanced. The speakers
allow you to hear what’s going to air without the need for headphones.
Headphone/microphone
Headphones allows the staff to block any background and listen to what being
played through the mixing desk. Doing this allows them to hear cleary what being
played through and allows them to have better control and fine tune the sound.
Headphones are needed as less noise is picked up so it doesn’t interfere with the
microphones. Some radio presenters and DJ’s wear headphones so they don’t
receive feedback, so when the monitors are muted as the microphones are on
the only way to monitor the broadcast maybe through headphones. Microphones
allow the host to speak into the audience and this sound is connected to the
mixer desk so I can be controlled all the time.
Digital cart walls/Play out systems
Cart walls and playlists are resources you gather before the show begins, so
jingles, adverts, and pre-corded things then are loaded into the system to play
during the broadcast. Play out systems form the broadcaster into broadcast
networks that deliver the content to the audience.
Soundproofing
This allows you to keep the sound to a minimum with no interference from
outside of the soundproofed room. The sound bounces of the wall and after
which soundwaves are flattened by the soundproofing reducing interference of
any other sounds.
