Broadcasting Principles & Practices (AB15) VAN JAYSON H. CASTILLO THE EQUIPMENT & BROADCASTING PROCEDURES Instructor THE RADIO BOOTH THE RADIO BOOTH Part of a radio station where the actual broadcast is produced and transmitted. It is designed to provide an optimal environment for clear sound recording and broadcasting. THE RADIO SET-UP (CONTROL ROOM) where the technical operations of the radio station happen. It ensures that all audio sources are balanced, timed correctly, and sent out at the proper broadcast quality. The role of the control room is to manage sound mixing, recording, and live feeds. THE RADIO SET-UP (CONTROL ROOM) Mixing Console (Audio Board) is the heart of the control room. It allows the sound technician to adjust audio levels, mix different audio sources, and control the overall sound quality. THE RADIO SET-UP (CONTROL ROOM) Monitors & Headphones Monitors are used in the control room to listen to the mix, while presenters in the booth use headphones to monitor their voices and program audio without feedback. THE RADIO SET-UP (CONTROL ROOM) Broadcast Software and Automation Systems Most modern radio stations use automation software to manage the timing and flow of broadcasts. These systems help schedule music, ads, and other content for live shows. RadioBoss, SAM Broadcaster, and NextKast are some popular automation programs that allow pre-scheduled playlists, jingles, and voiceovers to be played seamlessly. THE RADIO SET-UP (ANNOUNCER’S BOOTH) is the on-air room where the radio host or announcer sits during live broadcasts. The room is acoustically treated to provide a noise-free environment, ensuring clear voice transmission. It’s equipped with essential tools for the radio presenter to deliver content smoothly. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Microphone The microphone is the primary tool for capturing the announcer’s voice. High-quality microphones ensure clear and professional sound. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Headphones allows the announcer to hear their own voice, the program feed, and any cues from the control room. This helps ensure that the audio mix is balanced and there are no technical issues. Types: Closed-back headphones are often preferred to prevent sound from leaking into the microphone. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Monitors and Speakers While presenters mostly rely on headphones, some booths may have low- volume speakers for monitoring the broadcast off-air. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Talkback (Intercom) System This system allows the presenter to communicate with the control room or producers without being heard on the air. It’s used for coordinating on-air cues, timing, and instructions, especially during live shows. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Soundproofing and Acoustic Treatment Radio booths are soundproofed with materials such as acoustic foam, heavy doors, and double-glazed windows. This helps eliminate external noise and reverberation. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Program Clock A clock displaying the program’s duration, cue points, and commercial breaks to help presenters stay on schedule. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Soundproofing and Acoustic Treatment Radio booths are soundproofed with materials such as acoustic foam, heavy doors, and double-glazed windows. This helps eliminate external noise and reverberation. THE RADIO SET-UP (ANNOUNCER’S BOOTH) ON AIR warning light An ON AIR sign is a visual indicator that a broadcast is currently being transmitted live. The sign is typically placed outside of a recording studio or control room and is activated when a program or recording session is in progress. The sign is usually illuminated and may be accompanied by other indicators, such as a red light or a "live" graphic on a video monitor. THE RADIO SET-UP (SPECIAL ROOMS) Many radio stations have additional specialized rooms for different purposes. These rooms are used to support production, pre-recording, and editing. THE RADIO SET-UP (SPECIAL ROOMS) Podcast Booths Podcast booths are smaller, more intimate setups designed specifically for recording long-form conversations, interviews, or podcasts. These rooms are optimized for voice clarity, often utilizing advanced condenser microphones and multi-track recording devices for multiple guests. THE RADIO SET-UP (SPECIAL ROOMS) Voice-over Rooms These rooms are used for recording voice-overs or narrations. They are often treated with heavy acoustic materials to ensure zero sound interference and maximum voice clarity. THE RADIO SET-UP (RECORD LIBRARY) is a repository of all audio content, whether music, commercials, or other programming material. In modern radio, it’s not just about physical records but also about maintaining digital assets. THE RADIO SET-UP (SPECIAL ROOMS) Physical Records Vinyl, Cassettes, and CDs: Some traditional radio stations maintain physical collections, especially in specialized music shows (e.g., jazz or classical). THE RADIO SET-UP (SPECIAL ROOMS) Digital Libraries Hard Drives and Cloud Storage: Most modern radio stations use digital files stored on hard drives or cloud servers. The station’s automation system typically indexes and manages this library for quick retrieval. THE RADIO SET-UP (SPECIAL ROOMS) Archiving System Cataloging Systems: Whether physical or digital, radio stations use cataloging systems to organize and manage their audio files. Proper labeling and metadata tagging are essential for easy retrieval during live shows. WORKING TOOLS OF A RADIO ANNOUNCER Mixing Console (Audio Board) is the most critical tool for any radio announcer and the technical staff. It allows the announcer to control multiple audio inputs and outputs, ensuring everything sounds balanced and professional. Mixing Console (Audio Board) 1. Faders (red box) These control the volume levels of each audio input (microphones, music, sound effects). 2. Equalizer (green box) to adjust the balance between the different frequency components that make up a sound signal or changing the timbre of a sound signal. 3. Auxiliary Sends (blue box) These allow the sound technician to route certain audio to specific channels, such as headphones for talent monitoring. 4. Mute/Solo buttons (yellow box) enable/disable all signal routing from the channel strip. Channel strip LED Indicator Level Signal WORKING TOOLS OF A RADIO ANNOUNCER Turntable a traditional tool that has been used for decades, especially in radio stations that play vinyl records. While many modern stations rely on digital formats, some announcers still use turntables to add a classic touch to their shows. WORKING TOOLS OF A RADIO ANNOUNCER How a Turntable Works? Cueing Records Properly cueing (positioning) the needle on the vinyl record is essential for smooth transitions between tracks. The announcer gently places the stylus (needle) at the beginning of a song or specific track. They may "cue" it by slightly rotating the record back and forth to find the exact starting point before releasing it for playback. WORKING TOOLS OF A RADIO ANNOUNCER How a Turntable Works? Turntable Speeds Vinyl records come in different formats that play at specific speeds (measured in revolutions per minute, or RPM). The two common speeds are 33⅓ RPM (for LPs) and 45 RPM (for singles). The announcer must ensure the turntable is set to the correct speed to avoid distorted playback. WORKING TOOLS OF A RADIO ANNOUNCER How a Turntable Works? Turntable Speeds Slipmats allow the announcer or DJ to control the record's rotation without scratching the vinyl. Pitch control adjusts the speed of the track slightly to match the tempo of other music for smoother transitions. DJs can use pitch control to create a seamless blend between songs, especially in music-driven radio shows. WORKING TOOLS OF A RADIO ANNOUNCER Compact Disc (CD) Players is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. WORKING TOOLS OF A RADIO ANNOUNCER Key Features Track Selection - Allows the announcer to choose a specific track or segment from the CD. Announcers can quickly navigate between tracks using the player’s interface or remote control, ensuring the correct song or audio clip plays on time. Cue Function - allows the announcer to pause the CD at the exact point they want to start playing. The announcer cues the CD track before going on air to ensure smooth playback without dead air. WORKING TOOLS OF A RADIO ANNOUNCER Key Features Playback Modes - CD players may have various modes such as repeat, shuffle, or program mode, where specific tracks are played in a prearranged order. Announcers can set the CD player to automatically repeat tracks or play a pre-programmed playlist during their show. Digital Output - Many modern CD players have digital outputs to send high-quality sound to the mixing console or directly into a computer system. This ensures better sound quality when playing CDs through the broadcast system. WORKING TOOLS OF A RADIO ANNOUNCER Microphone it is the announcer’s primary tool for communicating with the audience. Radio microphones need to capture clear and professional-grade sound, and understanding how to use them is essential. WORKING TOOLS OF A RADIO ANNOUNCER Microphone Types Dynamic Mic - These microphones are robust, durable, and can handle high sound pressure levels. They are ideal for live environments and are less sensitive to background noise. Condenser Mic - are more sensitive than dynamic mics and capture a wider range of sound frequencies. They are used in controlled environments, such as pre-recorded shows or podcasts, where clarity and detail are important. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Microphone Techniques and Accessories Pop Filters or Windscreens These accessories reduce plosive sounds (like "P" and "B" sounds) that can cause popping noises in the microphone. Placed in front of the microphone, they act as a barrier, ensuring that the announcer’s voice comes through cleanly without harsh popping sounds. THE RADIO SET-UP (ANNOUNCER’S BOOTH) Microphone Techniques and Accessories Mic Positioning Proper positioning is key to achieving the best sound quality. Announcers are trained to position the microphone slightly off-axis (at an angle) and at a reasonable distance from their mouth to avoid distortion while maintaining voice clarity THE RADIO SET-UP (ANNOUNCER’S BOOTH) Microphone Techniques and Accessories Boom Arms A boom arm holds the microphone in place and allows for flexible positioning without the announcer having to hold the microphone. It keeps the microphone stable and ensures the announcer can easily move the microphone without noise interference. WORKING TOOLS OF A RADIO ANNOUNCER Microphone Techniques and Accessories Gain Control Adjusts the sensitivity of the microphone. The announcer or sound engineer adjusts the gain on the mixing console to ensure the microphone picks up the announcer’s voice at the right level without causing distortion or feedback. DONE
